TITLE: AN AUTOMATED METHOD AND PROCESS OF CONTINUOUSLY
REGENERATING A CLEANING ELEMENT WORKING IN A CLEANING
DEVICE
BACKGROUND OF TIlE INVENTION-FIEtD OF INVENTION
This invention relates to surface cleaning apparatus. more particularly and not construed to, cleaning apparatus For extended surfaces such as floor surfaces and vehicle paintwork surfaces in the domestic.
industrial and commercial markets.
BACKGROUND OF THE INVENTION-PRIOR ART
The present invention relates to surface cleaning apparatus, and more particularly, to an automated self-cleaning or self-regenerating surface cleaning device. In particular, the method and process of the self-regenerating surface cleaning device that includes a cleaning element configured to continuously clean and dry a surface while moving thru a regeneration module configured to apply a clean fluid onto the cleaning element and thereafter remove the mixture of the spent cleaning fluid and waste liquid and debris collected from the cleaning surface by the cleaning element.
The self.regenerating surthcc cleaning device may be configured to have other separate cleaning regions, a first cleaning section having cl9aning components configured to loosen and scrub conlaminants from a surface and prtceded by a second cleaning section having cleaning components configured to rinse and dry the surface being cleaned by the cleaning device disclosed herein. The self-regenerating surläce cleaning device may also include at least two containers for collecting waste particulates and liquids, and the other for storing cleaning fluids. The self-regenerating surface cleaning device may also have passive storage and support elements for supporting it on a surface being cleaned.
Wet cleaning apparatus for washing floors and vehicle surfaces are well known. These products come in a wide variety of different categories, types, styles, uses and designs. According to the present invention, wet cleaning products or devices fail short of sufficiently removing or wiping dry the cleaning liquids that they utilize in cleaning a surface. Also they fall short of performing microbial screening operations on [he waste material collected from surfaces. More aspects of this invention disclosure and its extensive scope of related product add-ability are discussed in various sections below.
Below, and not restricted to, are groups of various cleaning apparatus and methods divided into tvo main topics of discussions that the present invention can be subsumable to; (1)methods of manual and eJectronie car cleaning devices and (It)methods of manual and electronic floor cleaning devices for the domestic and industrial markets. Definitions of some of the terms used frequently in
this patent disclosure are hereby described.
The term surface' refers to any extended surface or object with a substantially wide external or internal surface that is painted or non-painted e.g. floor, wall, ceiling, window panes, tables, carpet, rug, airplanes, boats, body skin, vehicle paintworks-trucks, bus, train carriages, cars, motorcycles etc. A surface may be cleaned in order to free or disconnect it from dirt adhered on it.
The term washing and cleaning' refers to the action or process of using a clean cleaning fluid to agitate or scrub an object or surface in order to rid it of harmful or unwanted contaminants, then rinsing and drying it thus leaving it in a substantially clean state. Cleaning refers to the activity of making things or objects clean.
l'he term scrubbing' in cleaning refers to the combined use of agitating cleaning components and cleaning fluid to remove or free an object from dirt or impurities by rubbing. In most cleaning operations, scrubbing is usually the initial process carried out. Scrubbing is usually done by using a variety of cleaning components like brushes, sponges, abrasives. scourers, mitts, cloths, wools, synthetic cleaning materials etc. Scrubbing is generally done in conjunction with a cleaning fluid to remove, agitate or further dislodge or loosen contaminants from the surface or object being cleaned.
The cleaning fluid may be a soapy solution or soap added to the clean fluid before scrubbing commences.
The term clean fluid' refers to any liquid at whichever state, stage oVa cleaning operation, procedure or process it may be therein and that can dissolve and dislodged impurities from a surface or object, for example, a fresh or clean fluid e.g. water. A clean fluid is devoid of impurities and is capable to be used in removing and or dissolving undesired substances from a surface or object prefcrred in a clean state.
The (cnn cleaning fluid' refers to a liquid solution made from mixing a clean fluid such as water and a dissolved detergent or soap therein. This term may also represent any form of cleaning fluid or solution. Cleaning agents and products come in different forms and purposes, for example, in detergent, tablet, powder, stain remover, cleansers, soap, b'eaches, washing powders, washing up liquids, whilst other cleansers may come with additional or specific applications and purposes such as disinfectant, germicide, bactericide, sanitizer, purifiers, herbicides, antiseptic, antibacterial, biocides, microbicides etc. The most basic cleaning agents and methods are used for emulsifying, dissolving and corroding, in order to breakdown bonds of unwanted contaminants from an object desired to be cleansed, or the appearance further enhanced.
The term rinsing fluid' refers to a pure, plain or clear liquid free or devoid of any form of impurities such as elcaning agents. particulates orcontanlinant dirt. TI-ic term may represent a clean fluid such as water which is generally used to perform the act of rinsing. Generally, rinsing is to wash something lightly by dipping it in a pure liquid, cspecialL' clean water, or by running liquid over it usually as a second application of liquid so as to remove contaminants such as dirt and soap solution used in a preceding operation olserubbing a surlce or object desired to be cleaned. The rinsing fluid releases, loosens and dissolves contaminated fluid solution and particles of dirt from a surface or object that is being cleaned. The rinsing fluid may be a pure or plain liquid such as water with a mixture such as additives like antibacterial, disinfectant, bleach and drying agents added therein. The rinsing fluid may also be used to rinse-off contaminant fluid solution from a cleaning article such as a mop, sponge or brushes used during a rinsing operation on a surface, -by lightly soaking the cleaning article into the rinsing fluid and wringing-out the rinsing fluid from the cleaning article, thereby flushing or expelling contaminants from the cleaning article that may then be used again to further wipe and dry the surface of the object being cleaned. Rinsing fluid may also be a solvent such as spirits, hydrogen peroxide, iodine, chlorine, hydrides, bleach, vinegar etc., capable of dissolving other substances.
The term waste liquid' refers to a resultant solution consisting of clean fluid mixed with soap and dirt impurities held within a liquid suspension. Thus, waste liquid solution is a creation of spent liquids resulting from agitated and dissolved contaminants removed from a surface or object being cleaned via a preceding scrubbing and rinsing.cycle. Rinseate or rinse-olf liquid is a resultant waste liquid that is a lower concentrate mixture of clean fluid and or cleaning fluid, and contaminants dislodged from a surface or object during a cleaning operation.
The term regenerate' refers to the cleaning or renewal of a degenerated cleaning component that is used repeatedly to clean a dirty surface, whereupon, the regeneration of the degenerated cleaning component is performed by way of soaking the degenerated cleaning component into a clean fluid such as water, then rinsing the degenerated cleaning component to loosen and detach contaminants and then wringing the degenerated cleaning component to expel the contaminant or waste liquid held within the cleaning component thereby transforming the degenerated cleaning component into a regenerated cleaning component that is capable of being reused again to continuously make clean and or dry a dirty and or wet surface. Other ways of regenerating a constantly degenerating cleaning component during a cleaning operation may include suctioning, blowing, vibration, centrifugal force, and beam ray, etc. The term dirt antI contaminant' as used herein broadly refers in any foreign matter such as road salt-grit, sand, road-film, insect remains, mud, grime, stains, clay, particles and particulates to be removed from a surface or object to be cleaned. Contaminants may also include the mixture of dirt and a used cleaning agent.
METHODS OF MANUAL AND ELECTRIC FLOOR CLEANING DEVICES
Cleaning is the broadest and most widespread activity performed around the entire world by all forms of living things. Thus, the cleaning industry is one of the most robust few areas of industry least affected by the economic recession because it has a major advantage over most other industries as A. buildup of dirt never stops. The cleaning industry sector is an essential commodity and regardless of economic set-backs, clean hospitals, clean homes, clean schools, supermarkets, restaurants, cars, airports, offices, streets, trains and among others are always need regular cleaning, making the market recession-resistant. Therefore, maintaining standards of hygiene to protect against maladies caused by infection contributes towards wider health outcomes and benefits by reducing unnecessary morbidity and mortality. With the current health threats and emerging contagious diseases, the importance of hygiene is becoming more appafent as it is no longer a case ofjust keeping the surfaces of objects looking clean, but for (he health ofa community, society and the entire nation.
Therefore, with approximately over 18,000,000 domestic houses in the UK, and a similar or larger number of homes in most developed countries of the western hemisphere, and a similar or much larger number of homes in most developed countries of the western hemisphere, south America, southern Africa, Australasia and Japan, a wide variety of manual and electronic floor cleaning apparatus and cleaning products that have emerged over the past years. Thus, there are a variety of manual and electronic floor cleaning apparatus available in the market, namely wet floor cleaning apparatus. Wet floor cleaning in the home has long been done manually, but recently, more electrical apparatuses are increasingly being used in the home floor cleaning arena.
The most common traditional manual method used for cleaning floor surfaces has long been done using a wet mop made from several strands of fluid absorbng material or a block of fluid absorbing sponge attached to the end of an elongated hapdle.
The mop or sponge is dipped into a container filled with a cleaning fluid, to absorb an amount of the cleaning fluid into the mop or sponge, and then moved over the surface to apply a cleaning fluid onto the surface. The cleaning fluid interacts with contaminants on the surface and may dissolve or otherwise emulsify contaminants into the cleaning fluid. Thereafter, the same sponge or mop is used to absorb the waste liquid from the surface. While clean water can be effective for use as a cleaning fluid applied to floors, most cleaning is done with a cleaning fluid that is a mixture of clean water and soap or detergent that reacts with contaminants to emulsify the contaminants into the water.
Additionally, it is known to clean floor surfaces with water and detergent mixed with other agents such as a solvent, a fragrance, a disinfectant, a drying agent, abrasive particulates and the like to increase the effectiveness of the cleaning process. It is possible to perform more than one successive cleaning stage, step or process on a floor surface depending on, and among other factors the concentration of dirt on a particular floor surface or floor temperature. The sponge or mop may also be used as a scrubbing apparatus lhr scrubbinEhe floor surface, and especially in the areas where the contaminants are par icularly diflicult to remove from the floor. The scrubbing action serves to agitate the cleaning fluid Ibr mixing with contaminants as well as to apply a friction force for loosening contaminants from the floor surface. Agitation enhances the dissolving and emulsifying action of the cleaning fluid and the friction force helps to break the bonds between the floor surface and the contaminants.
One major drawback with contemporary manual floor cleaning methods or prior art is that after cleaning an area of the floor surface, the waste liquid must be rinsed from the mop or sponge, which is usually done by dipping the mop or sponge back into the same container filled with cleaning fluid.
This rinsing step contaminates the cleaning fluid with waste liquid and the cleaning fluid becomes more contaminated each time the mop or sponge is dipped back into the container with the rinsing liquid. As a result, the effectiveness of the cleaning fluid deteriorates as more of the floor surface area is cleaned. Thusly, no actual cleaning takes place. Some cleaning containers have been made with double-buckets that keeps separate the cleaning fluid and rinsing fluid, but eventually suffer the same liquid deterioration as described above.
While the traditional manual method is effective for floor cleaning, it is labour intensive and time consuming. Moreover, it's cleaning eFfectiveness decreases as the cleaning fluid becomes contaminated. Thus, this cleaning method and related devices lacks other functionalities, benefits and
features identified in the present disclosure.
Floor cleaning mops with refill' sponges, pads, wipes or absorbent micro-fibre cloths require the absorbent or wiping element are not any more different in use or cleaning methodology to the conventional manual bucket and mop cleaning apparatus as they; require to be consistently manually replaced during in between a cleaning operation which is a time consuming and wasteful, expensive as it adds to countless rinsing cycles and washing machine cleaning of the refills. Furthermore, they expose people's hands and fingers to direct contact with hazardous cleaning chemicals, bleaches and microbial contaminants whenever the refills' need the regular handling manual changing. Changing refill mops at such close range to the face can be perilc'is duc to the hazardous chemical fume emissions and risk of possible chemical splaies, such as bleach to the mouth and eyes during the manual releasing of the mflll mops From the frame cleaning head. Thus, this demanding refill mops can be frustratingly tedious to work with which can be a recipe For carelessness when manually changing the micro-fibre or sponge refills, constant wringing, rinsing, and reattaching them to the frame of the cleaning head, Also, the wringing of sponge mops and some mierofiber mops have a wringing system usually comprising a lever attached to the collapsible cleaning head where the sponge or microfiber is attached, and by twisting or forcefully pulling or pushing the lever on the handle boom towards or away from the user, so as to rinse and flush the cleaning head can be a repetitive and gruelling task. Thus, the degree of drying and general hygienic level of the cleaning surface depends on the strength of the user. The same backbreaking tasks are common to users using container buckets that have a cleaning mopping head wringing system comprising a lever connected to a clamping configuration generally attached to the rim of a bucket, for flushing or rinsing out contaminants and cleaning fluid from a cleaning mopping head. Thus, these types of cleaning mops are not any more different in usc or cleaning methodolog;' to the conventional manual bucket and mop cleaning apparatus which is as hand wrenching and gradual cleaning fluid deterioration occurring, among other disadvantages spreads germs easily across a floor surihce being supposedly cleaned. A further drawback is that prior to washing ihe floors, vacuuming the floors is carried out first using vacuum cleaners doubling or tripling tasks on a given floor area which is not only tiresome but wastes time. On Tuesday, July 20" 2010, an article on page 43 of the Daily Mail newspaper shows a leading London osteopath discussing health issues regarding use of heavy vacuum cleaners which can easily cause injury to spinal discs, muscle cartilage or other soft tissue as one hangs over stooped in the mid-stance posture-which our bodies are not designed to be in for any length of time especially if one has an existing back problem. This can help trigger catastrophic back pain. The osteopath encourages people to look for the lightest vacuum cleaner possible and keep movements close to the body so as to minimise any stooping and stretching, and also encourages smooth floors such as the wooden floors (which he has in his house) as one is less likely to sustain a back injury.
Thus, above floor cleaning methods and related devices lacks other functionalities, benefits and
features identified in the present disclosure.
A need exists in the art for an improved method for wet cleaning a floor surface. That is; a device that is easy to usc and lightweight to work witic; a device that automatically performs the tasks of (i)scrubbing, (ii)rinsing and (iii) drying olany cxtcnded floor surfaces in one single instant, stroke or pass; a floor washing device that does not leave hiatus by wasting vital time intervals between scrubbing, rinsing and drying since dislodged contaminants and bacterium can dry up on a surface being cleaned, or drip, soak and sip further into tiny unreachable crevices or grout-lines on the floor surface being cleaned. Also, to provide an affordable lightweight, easy to use and maintain floor cleaning apparatus for automating wet floor cleaning in the domestic and industrial markets.
Electrical floor cleaning apparatus are well known and are gradually penetrating the domestic market.
A recent improvement in the electrical wet floor cleaning apparatus in the home is disclosed in U.S. Pat. No. 5,968,281 by Wright et at., and assigned to Royal Appliance Manufacturing and entitled Method for Mopping and Drying a Floor. The disclosure of the 281 patent is herein incorporated by reference to its entirety. Disclosed therein is a low cost wet mopping system disclosed by Wright et at,. comprises a manual floor cleaning apparatus having a handle with a cleaning fluid supply container supported on the handle. The devic6 includes a cleaning fluid dispensing nozzle supported on the handle lbr spraying cleaning fluid onto the floor and a floor scrubber sponge attached to the end of the handle for contact with the floor. The device also includes a mechanical device for wringing waste liquid out of the scrubbing sponge. A squeegee and an associated suction device are supported on the end of the handle and used to collect waste liquid up from the floor surface and deposit the waste liquid into a waste liquid container, supported on the handle separate from the cleaning solution reservoir. The device also includes a battery power source for powering the suction device. While Wright et al., describes a self-contained wet cleaning apparatus as well as an improved wet cleaning method that separates waste liquid from cleaning fluid, the device is manually operated I. which makes it laborious and repetitive intermissions when the device is in the suction mode. It may only take a moment or two before one has to repeat this cycle each time and adds-up to countless tasks and a lot of time wasted during an operation. Furthermore, while the scrubbing component is continually used to pick up waste liquids, the scrubbing component is not rinsed or sanitized, thus degrading the efficiency and hygienic competence of the cleaning operation, also allowing for the transmission of microbial elements. It lacks other functior.alities, benefits and features identified in
the present disclosure.
A similar suction squeegee for removing cleaning liquid from a floor surface is disclosed in U.S. Pat. No.5,067.199. However, this suction squeegee does not eliminate the various manual tasks and processes involved in floor cleaning because a conventional mop and bucket must be used prior to use of the suction squeegee device. In addition, this suction squeegee has the disadvantage of requiring three or four separate devices to perform the cleaning operation; including the suction squeegee, a mop, a mechanism to wring dirty water out of the mop, and a bucket. Therefore, since the same mopping element is continually used to pick up waste liquids and is not rinsed or sanitized. It deteriorates the efficiency and hygienic proficiency of the cleaning operation and can also allow for the transmission of microbial elements. Thus, it lacks many features, capabilities, and functionality of the present invention described further herein.
The robot is circular in shape thus incapable of reaching room corners. l'hus, the robot is limited in undertaking. scope and appears overstretched, haphazard and unpredictable to work with.
Furthermore, it lacks many features, capabilitIes, and functionalily of the present invention described further herein.
With regard to the above problems discussed in this section, there exists a need in the art for an affordable floor surface cleaning device that can successively perform all the above. elementary cleaning operations and stages thereof at once. That is, a new generation of surface cleaning device that automatically sanitizes a surface whilst performing the progressive stages ot (1) scrubbing, (2) rinsing and (3) drying of any extended surfaces, and in this case, to clean floor surface in one single instant, stroke or pass. A floor surface cleaning device that is stylish, easy to use, time saving, safe and comfortable to hold, tidy to work with, durable, portable lightweight and has a cordless option, use minimum water and electrical resources, and affordable to the domestic market as well as being cost effective to use and maintain, ecological to manufacture and maintain. That need is addressed by the present invention in this patent disclosure. The various functions, features, and benefits thereof are described in more detail further below.
METHODS OF MANUAL AND ELECTRIC CAR CLEANING DEVICES
With over 30,000,000 cars in the UK, and a similar or much larger number olcars in most developed countries of the western hemisphere, south America, southern Africa, Australasia and Japan there are a vast variety of manual car cleaning and electronic car cleaning apparatus and cleaning products
S
available in the market today. The most usual basic common manual method of cleaning an ordinarily sized family car is commonly referred to as the buckee' and sponge method which can be carried out by using at least one sponge and bucket Ill led with clean water. However, it is much easier to have at least one set of each, for the soap and rinsing cleaning stages consecutively. To carry out the operation, one of the two buckets of water is mixed with soap. Then, following the basic steps of cleaning; (I) scrubbing with a soapy liquid solution, (2) rinsing with clean fluid generally water and (3) drying or wiping the car using a soft clean material are performed.
The methodology and processes involved in this type of car washing will be described below in a more detailed manner whilst citing out its main disadvantages.
A common domestic manual method of car ashing is done by use of water delivered via garden hosepipes. This method of cleanirj a vehieJe is similar to the well-known conventional bucket-sponge car washing method, minus the buckets. The surface of the vehicle paintwork is scrubbed using sponge and cleaning fluid and the contaminant liquid on the vehicle bodywork rinsed down by water emitted from a hosepipe. The process of washing cars in this manner is exceedingly wasteful due to the vast and excess amounts of water resources wasted away. Similarly, using the jet washing method discussed hereby to wash vehicle paintwork is equally wasteful, messy, labour intensive and un-ecological. It also adds up to the water utility bill.
Another common type of electrical car washing device is the high-velocity jet-stream pressure washers, more commonly know-n as jet-washer, consisting of an electronic motor that is fed in with water from an ordinary hosepipe then pumping and releasing the water at high velocity into a narrow wand or sprayer that is controlled by depressing a trigger gun on and off by hand. Although this process is similar to using the hosepipe. hereby, the velocity of the water is highly increase by a powerful electronic motorised water dispenser which forces out a jet of' water at high velocity from the distal end of the narrow pole handle. Some petrol stations advertise this type of car washing as touch-less for customers who are not keen in taking their vehicles into tunnel carwashes. These self-serve car wash jet washers in petrol stations are operated by coins, credit cards or tokens.
A disadvantage of this self-serve car wash bays is the inherent race against time one has to go thru in order to complete washing the vehicle before a certain time allocated by the amount of money inserted into the machine elapses thus turning off the machine, which requires more money in order to be turned on again. Another disadvantage is a rationed cleaning agent such as shampoo. A disadvantage of this method of washing a vehicle is the messiness involved by being sprayed back by the dirty water reflecting from uneven vehicle paintwork, dirty wheel and sudden headwind carrying the jet wash mist and contaminants therein into a customer's face and clothing. These machines are thus expensive and lack many features, capabilities, and functionality of the present invention described further herein.
Another type of ear cleaning plants developed specifically because vigorous gantry car washing brushes harmed peoples vehicle paintwork is the touch less or no-touch car washing tunnels which consist of an alTangement of jet wash type nozzles fixed around an arch like support structure that rolls back and lbrth to clean a stationary vehicle by expelling a high velocity jet stream of powerful detergents formulas and rinsing liquids. There is no contact with friction so the likelihood of any damage is reduced. However, the touch-less carwash does not clean nearly as well as a frictional application.
The main disadvantage of jet-washer, self-serve car washers and touch-less or no-touch car washing tunnels is that the cleaning is dependent entirely on the chemical action of the strong soap and the high velocity jet-stream to remove dirt-film. While it might clean off a covering of dust or light dirt, this type of wash leaves a dirt-film residue when a heavy road-film is present. Thus, they cannot be used entirely on their own since further work of scrubbing on the car surface by sponge, brush as well as final wiping by chamois has to be carried out manually. Also, light fittings like skirting design tapes and rubber seals can be plucked offtheir fitting due to the powerful velocity of the liquid thrust from the electronic motors. Rusty or weak paintwork areas can be exacerbated by the force of the jet stream as well. Thus, as is with garden hoseipes, jet washers waste substantial amounts of water resources and electricity which is un-ecological and adds up to the utility bill. More disadvantages related to cleaning vehicle paintwork surfaces using electronic jet washers and manual garden hosepipes will become more apparent from further discussions below. Thus, the above methods and devices for cleaning vehicle paintwork surface lack structure, proficiency, and practicality of the present invention described further herein.
Another type of car cleaning apparatus similar to thejet wash is a rotating brush fixed at one proximal end or head of a pole and is turbine-power-rotated by the force of the water coming into the pole via a garden hose-pipe from the other distal or opposite end of the pole or powered electronically, and a water ejecting orifice or nozzles located at the stationery or rotating brush mechanism and being adapted to scrub and apply fluids on the surface of the car being cleaned.
For example, U.S. Pat. No. 6.748.619 by Quach, entitled Hand Held Electrical Cleaning Device, discloses a complex car cleaning apparatusAvhich consists of a lengthy adjustable elongated pole with a rotating brush assembly attached to one end and a handle assembly that includes a battery housing and a hand-grip assembly with a brush control switch and a hose connector fitting for a water conduit disposed inside the elongated pole and terminates in the brush assembly to deliver water to the brush assembly and a soap delivery system to deliver soap to the water conduit. Water models similar to the device disclosed in the patent 619 have the same disadvantages are expected from the water-powered pole brushes known in the market. Another disadvantage seems that this device is prohibitively expensive to manufacture whereas its results are non-different from using the readily available water-powered brush and pole cleaning apparatus available in the market. Furthermore, -ft these devices use and splash more water and as their brushes and bristles wear out, the more they scratch vehicle paintwork. Scratching or accidentally hitting a vehicle paintwork surface with the long pole, motor housing and shrouds at the brushing area is another disadvantage. Also, there is no provision for a high-velocity jet-stream of water to hydraulically run-offa large portion of dirt before using the brush to clean only the remaining dirt film; thus, when the brush is placed directly to a heavy coating ol' diii without an initial water run-ofl nec-dless paint scratching occurs due to the friction between the brushes and the parti;les or granules of dirt on the paintwork. Equally objectionable, it is difficult to run-olithe loose dirt and soap by using rinse-water while the brush is in the way and much time and water resources are wasted because the scrubbing, rinsing and the drying operations must be done separately-one process after the other. Thus, it Jacks many features, capabilities, and lunctiunality of (he present invention described further herein.
An example of a mechanised drying device in the car cleaning industry is that of (iS. Pat. No. 6,571,586 by Michael Ritson eta!., entitled Portable Wringer, discloses a leather chamois drying device comprises a support structure with a pair of rollers attached to it and a manual crank handle, whereby the support structure carries a suction device for attaching the device on a vehicle body. This device although only removes the task of wringing a leather chamois by hand, it does not address the need for removing the laborious other tasks associated with car cleaning namely; scrubbing, rinsing, carrying buckets of water, splashing, timing and drying a vehicle by hand. Furthermore, a device of this nature perched on its own unattended may drop causing damage to vehicle bodywork or the user.
It may also become a tripping hazard. Thus, is_lacks many features, capabilities, and functionality of the present invention described further hereiji.
Gantry commercial or in-bay automatics type car cleaning plants more commonly known as car-wash machines in the UK and often seen in service station area consist of a large movable chassis or framework along a track or rail and adapted to roll back and forth over a stationary vehicle. Affixed upon the support chassis is an automatic washing machine with rotating brushes and liquid dispensing nozzles for cleaning the external painted surfaces of cars and are normally seen operating in petrol stations bay areas. Another Less common car washing type plant in the UK are the tunnel washes more common in the USA and continental European countries, which use conveyors to push or pull the vehicle through a series of fixed cleaning mechanisms. These plants are very expensive to purchase and build since they require architectural planning, public control, excavation etc., and consume vast amounts of electrical energy and water resources. Generally, tunnel type car washing plants are industrial machines which operate on a 3-phase electrical interface of4l5volts and consume up to litres of water just to clean a single vehicle leaving a negative environmental footprint. Thus, one of the main disadvantages of this type o[car washing plants is an ecological or environmental factor since this ear wushing plants consume disproportionate amounts of electrical and water resources just to clean a single car. Another ecological disadvantage is the contamination of surface waters, soil and groundwater through chemical and contaminants leaching. Contamination of surface waters arises from the rinseate contaminants discharging to storm drains, which subsequently drain into rivers and lakes, thus disrupting hydrological, hydrobiological and hydrographical cycles and balances in the soils which deplete soil nutrients, contamination of water tables and inhibition of the growth of plants nearby and near riverine vegetation areas and water catchments thereof. The main pollutants found in wash waler from such carwash plants include oil, grease, phosphates and lead. Also, since these machines usually operate in dark or poorly lit claustrophobic enclosures, the cleaning nature of this plants coupled with vigorous shuddering is not a favourite to most people, and especially young children who tend to get frightened easily. Because these car washing plants treat every single car as though it were the dirtiest portion of the dirtiest car, even though the car is not very dirty, they inherently cause needless extra paint scratching thus many people have rejected gantry car washers lhr this reason alone as they tend to leave arrays of scratches in the shape of a bristle Filaments commonly known as brush niarks, on the vccle's paint. The scratching or hazing is worst when a rotating brush holds sand or grk from a previous car and then scratches the following cars. Thus, due to the nature of these heavy duty carwash plants. powerful motors, strong detergents, soaps, unyielding industrialized brushes and bristles therewith, vehicles begin to show an array of hair-line or hazy scratches all over their paintwork's lustre only after a few visits to these car washing plants.
Thus, hazy brush marks scratches are especially visible on reflective rounded surface areas of the vehicles paintwork causing vehicles to lose their enhanced aesthetic appeal. Furthermore, because petroleum based paints are becoming phased-out in the near future to comply with Environmental Protection Agency regulations, vehicle manufacturers are now adjusting to various options of paints such as water based acrylic latex paints laminated in a protective layer of a protective pristine skin of synthetic glossy coating that is similar to clear varnish. The glossy lacquer of this type of protective coating is much delicate than the sturdier traditional vehicle oil-based paints. Thus, abrasions from car washing plants, general frictions and washing using prior art hand held car cleaning apparatus on this new type lacquer shall rapidly become more apparent from just a few washes. To that, these gantry plant car washing machines are expensc to use and are not flexible enough to do the cleaning job of washing and drying vehicle paintwork well enough for every single difterent make of vehicle's paintwork that they wash. Moreover, the vigorously rotating industrial brushes are known to break or disjoint vehicle fixtures like wind shield wipers and washer nozzles, outside mirrors, drip moulding, radio antennas, roof-racks, spoilers, 4x4 spare wheel protective covers and relative attachments. This car washing plants are also known to be incompetent in cleaning inwardly and lower inwardly curved lower vehicle body side mouldings. Industrial car washing plants are also known to be incompetent in drying vehicle bodyworks thoroughly. Finally, and among further disadvantages, they cannot see therefore cannot repeat a task if a portion of the painted bodywork is left unclean or untouched. Other disadvantages related to the automatic or gantry type car wash plants will become more apparent from further discussions below. Gantry commercial type car cleaning plants therefore lack many features, capabilities, and functionality of the present invention described further herein.
Another rare type of car cleaning is (lie waterless or hydrophobic car wash or dry wash technique.
This method involves the non-use of water to clean a vehicle by using a mixture of various emulsifying ingredients in successive turns of thorough intensive application by hand to the vehicle paintwork. The FOCCS5 is difficulL extrerdely laborious and time consuming because of the demanding spot cleaning and rotations ol cycle per variety of different chemical applications undertaken during the cleaning ofa vehicle. A main disadvantage of this kind ofdirt removal from a delicate vehicle surface is that causing abrasion to the paintwork of the vehicle is apparent through the vigorous rubbing of contaminants, grit and dirt against the paintwork. Thus, it lacks many features, capabilities, and functionality of the present invention being described herein.
Flexible cleaning blades or silicone wiping blades are available in the common market although rarely used by the occasional car cleaner. They consist of a thin flexible, usually rubbery blade that is laminated or fixed to a handle, and are normally about a foot in length. Although they are usually advertised as better a substitute for the tedious leather chamois, they fall short of wiping a vehicle surface adequately since they leave stretches of streak marks on vehicle paintwork and are unable to mould to vehicle surface contours and curvatures leaving the need for manual intervention using a semi-dry chamois or other cleaning material. Fifth Gear, a British motor vehicle enthusiast's programme aired on Channel Five at 8pm.en the 5d January 2009, showed intensive detailed disadvantages and various adversc effects left on a vehicle paintwork cleaned using flexible silicone blades. Thus, it lacks many Ibatures, capabilities, and functionality ol' the present invention being described herein.
Therefore, it is not surprising that the most common and yet complex manual car cleaning method is done using the conventional widely accepted method consisting of a pair of sponges and buckets filled with water, soap and a semi-dry cloth commonly known as a leather-chamois in the carwash business.
l'o carry out this task, the person cleaning the vehicle surface utilizes the well-known elementary universal procedure of cleaning an object, that is; a first step or stage of scrubbing. Scrubbing removes unwanted dirt from an object. Unwanted dirt or contaminants mixed with solid tiny particles are loosened and separated from thc object desired to be cleaned by use of soap or detergents. A scrubbing component such as a sponge, brush, scouring pads and microfiber mitts can be used; a second step or stage is rinsing. Rinsing is done to let loose or free the object from contaminants looscncd by the scrubbing action in Ihe first step. Rinsing is done using a fresh or pure rinsing liquid like water; a third and usually final step in cleaning an object is the step or stage of drying the object.
Drying the object removes spent liquids from the above two preceding steps.
Drying can be done by air drying, wiping or blowing. In the vehicle cleaning or car cleaning industry, these fundamental three steps are used to clean the surfaces of any vehicle paintwork. Drying is usually done by wiping runoff water from the vehicle bodywork as it further enhances shine appeal.
Blowing powerful thrusts of air at high velocity is also used by gantry car washing plants. Thusly, the three basic cleaning steps or stages of cleaning an object are (I) scrubbing (2) rinsing and (3) drying.
These three steps or stages used in cleaning a vehicle as mentioned above shall now be discussed below in their basic categorical processes and capacities as generally undertaken by one wishing to clean the painted surface ofa vehicle's bodywork manually.
SCRUBBING
Tlictirst step or stage undertaken when IManually c!eaning a vehicle's external bodywork or paiinwork is the scrubbing task. A person tills at least one or two buckets with fresh or clean fluid, in this case water, then dispenses a small amount o[detergent or soap, ordinarily known as car shampoo into one of the buckets of fresh liquid of which the person uses this soap fluid solution or cleaning fluid to clean a car in the first or initial cleaning stage only.
The person begins by removing unwanted contaminants or dirt particles from the surface of the vehicle paintwork by immersing one of the two sponges in the bucket containing the shampooed or cleaning fluid in order to absorb and retain a sufficient amount of the cleaning fluid into the sponge's permeable pores. The person then moves the sponge over the surface of the vehicle's paintwork, applying the cleaning fluid onto the surface of the paintwork in the preferred circular or longitudinal scrubbing movement, [he scrubbing serves to agitate the cleaning fluid for mixing with contaminants from the vehicle paintwork surface. Agitation enhances the dissolving and emulsifying action tin the creaning fluid, The friction three herps to break bonds between the vehicle paintwork surface and the contaminants.
As the person continually scrubs the vehicle palutwork surface, the cleaning fluid within the sponge's pores is gradually being transformed into a mixture of waste liquid. This waste liquid includes a combination of the cleaning fluid and contaminants from the vehicle's surface being cleansed, and are held in suspension within the sponge's permeable pores. At this particular moment, the sponge is not effectively cleaning the surface of the vehicle. Therefore, the person has to re-immerse the sponge that has within it suspended contaminants back into the bucket of the cleaning fluid whilst simultaneously maling tight grasps using the fingers against the submerged sponge. The finger grasping action against the submerged sponge forces the contaminated liquid and solid particulates in the sponge to leave thru the permeable pores of the absorbent sponge. This action simultaneously replenishes the sponge with a fresh measure of the cleaning fluid. However, each time this sequence is done, the soapy water is further contaminated. Eventually the gradual transfer of contaminants via the sponge from the vehicle paintwork surface saturates the bucket of cleaning fluid into a dirty solution. Thus. ti-cre is no further effective cleaning action taking place and the dirty cleaning fluid has to be rcnewcd. Carrying out ihe tasks in this first stage is tedious, repetitive and messy.
Stubborn stains like caked bird marks and insect's carcasses more commonly known as bugs are usually stuck on the frontal lamp, grill and side mirrors areas of a vehicle and are particularly strenuous to remove. The task of removing bugs requires more liquids, scrubbing force and detergent.
Sometimes, people are distressed after realising that an intense fit of concentration to remove a usually small hardened or caked bird dropping off their vehicle paintwork leaves a much larger and permanent scouring mark. Other semi-permanent or missed marks are also removable using various vigorous approaches which involve exerting a great deal of pressure on the feet, knees, back, shouLders, hands, wrists and fingers tbr grasping the sponge tightly whilst persuasively rubbing the stubborn stain using by rotational or lateral repetitive motions in order to force-free the stain. Thus, due to the laborious nature of manual car washing, it can be a perilous job for senior persons or anyone else who suffers from various cardiovascular orjoint disorders due to the heavy lifting and ferrying heavy buckets of water. To healthy people, this back-breaking tasks can be frustrating, difficult, and leaves them out of breathe and exhausted. Furthermore, it can be risky where a person is in an awkardly bent position and scrubbing the same time. There are many cases whereby people have been known to twist or wrench their backs, hips and ankles white cleaning their vehicles manually. It is also uneconomical since a lot of rinsing liquid is required and wasted which adds up to the utility bill. Furthermore, the tasks of car washing are inherently messy since dirty liquids are splashed all over the person's body, feet and floor surface.
RINSING
The second step or stage is the rinsing task when manually cleaning a vehicle's external bodywork or paintwork. Here, the person uses the other of the two buckets by filling it with rinsing fluid, preferably water, and this time not administering any cleaning shampoo. This procedure is similar to the first task of scrubbing since the equivalent cleaning pattern or action is repeated but this time with lesser pressure applied on paintwork surface since the contaminants have already been loosened by the scrubbing action done in the first cleaning stage. To do this, a clean sponge is dipped into the rinsing fluid in order to absorb and retain the rinsing fluid suspended in sponge's pores, then passing the sponge over the vehicle painiwork surface in a continuous motion of circles, horizontal or vertical movements depending on the area and surface of the vehicle being cleaned. Nudging the sponge with a moderate grasp allows more rinsing fluid to spread on the loosened contaminants. This action forces Lifting of the contaminants and mixes them with the rinsing fluid thus into a weaker diluted solution which readily drips off or runs-off the surface of the vehicle paintwork with ease. Once the rinsing fluid has been dissipated from the sponge, the sponge is no longer rinsing effectively. Therefore, the sponge is once again dipped into the rinsing fluid whereby held contaminant particles and dirt inside the sponge's pores are rinsed off using a light restrained grasp on the submerged sponge. This action expels the contaminants and particulates held in the sponge's liquid suspension in exchange for a fresher amount of rinsing fluid. However, the effectiveness of the rinsing fluid deteriorates further each time the sponge is rinsed. Thus, the need for a new refill of fresh rinsing fluid is required since the continual submersion and replenishment of the sponge to-and-from the vehicle pairitwork surface gradually transforms the rinsing fluid in the bucket into a more contaminated solution.
During hot or warmer weather, cleaning fluids plus dislodged contaminants dry up very rapidly during the first stage of cleaning vehicle paintwork. When commencement on the second stage begins, the process is made more arduous andtomplicated because the loosened dirt and particulates loosened in the first stage of cleaning become dried up and stick on the surface oF the vehicle's paintwork. Quickened drying can also be increased by windy situations.
Therefore, by the second stage of rinsing, the person has once again cleaned around the perimeter and roof of the vehicle at least twice; i.e., once (or more times) in the first stage of scrubbing it, and at least once again in the second stage of rinsing the vehicle. This portrays a picturt of the tasking and unnecessary repetitions involved.
DRYING
The third step or stage is the wiping or drying task undertaken when manually cleaning a vehicle's external bodywork or paintwork. In this process, the person needs to swiftly dry the run-off of the rinsing fluid holding onto the surface of the vehicle paintwork before it dries up. To conduct this operation, the person submerges a semi-dry cleaning m?teriaI commonly known as a leather or chamois into a bucket of rinsing liquid, in thi case water and shakes it whilst its submerged so that particles and contaminant solution is released. The person then removes the chamois from the bucket of rinsing fluid in order to rid the chamois off excess retention liquid. To do this, the person folds the wet chamois in an ideally tubular shape, then fold it to itself so that they can manageably wrap their hands and fingers tightly around either of the two longitudinal ends, then applying a firm grasp of force in their hands whilst simultaneously wrenching or twisting the wrists of at least one hand at the opposite direction of the longitudinal axis of the folded chamois. This intense compressing action on the chamois forces the retained liquid held within the chamois' permeable pores to become expelled and thus extracted out of the wrenched and compacted chamois. The chamois is then unfolded and spread out on the surface of the vehicle paintwork surface being cleaned, before continuing to wipe or rub the wet surface of the vehicle being dried. The tighter the wrenching grasp is for purging liquid off the chamois, the more improved is the chamois absorbent capacity and drying result on the vehicle paintwork surface. However, it is not long before the straining effort of wringing the chamois has to be repeated again since the chamois quickly becomes soakr.d with liquid scattered across the surface of vehicle paintwork in just a few shun stroke of the arm. Not only is the wringing operation a hard task when carried cml by hand anti bearing in mind that chamois tend to he slippery by natural occurrence, it is difficult to obtain an even degree of dryness ofthe chamois and consequently that of the vehicle paintwork surface being dried. Moreover, tight actions of grasping, wrenching, compressing and twisting the chamois during wringing can cause chafing of the hands, muscle cramps and fatigued joints. Using protective gloves to wring a chamois in order to avoid ehaffed hands is impractical since the gloves slip and stretch between the fingers which is displeasing and requires double the effort to attain the same degree of wringing without gloves. Additionally, the wrung-out water can find its way to the clothes or feet of the person cleaning the vehicle as well as the floor surface posing a slipping hazard.
Finally after the vehcte surface has been satisfactorily dried, the person has walked around the vehicle periphery at least three times; scrubbing it, rinsing it, and drying it. It not only is manual car cleaning a wearisome task, it is highly time consuming. Furthermore, during hot or warmer weather, the second cleaning stage dries quicker. Therefore, before one embarks upon the third stage ofdrying, the process becomes problematic as the rinsing fluid used in the second cleaning stage dries on the surface of the vehicle paintwork. thus spreth visible streak marks and water run-off drip markings are left behind. These marks are made by the dispersion of tiny solid particles further dislodged by the rinsing fluid's action from the second stage of rinsing. These particles are left stuck on the surface of the vehicle paintwork oncc the suspension of the holding liquid therein evaporates. Wiping the painiwork surface at this moment is not preferable as the combination of rubbing a semi-dry chamois against vehicle paintwork deteriorates the situation further by spreading streaks and smudge marks across the surface. Morcover, friction between the semi-dry chamois and the dispersed tiny solid particles stuck on the dried paintwork can cause permanent scratches. An only viable solution is to quickly repeat the entire rinsing stage fast, as vehicle surface paintworks shine best when wiped dry whilst still cool and wet with rinsing fluid.
With regard to the above problems discussed in this section, there exists a need in the art for an affordable vehicle paintwork cleaning device that can successively perform all the above elementary cleaning operations and stages thereof at once. That is, a de ice that automatically performs the stages of; (I) scrubbing, (2) rinsing and (3) dryingMf any extended surfaces, and in this case, to clean a vehicle's paintwork in one single instant, stroke or pass, as older ofl and modern water based vehicle paintworks respond best to for brilliant streak-less shine by having paintworks dried when still wet and cool with rinsing fluid, generally water. A vehicle surface cleaning device that is stylish, easy to use, time saving, safe and comfortable to hold, tidy to work with, durable, portable lightweight and has a cordless option, use minimum water and electrical resources, and affordable to the domestic market as well as being cost effective to use and maintain, ecological to manufacture and maintain.
That need is addressed by the present invention in this patent disclosure. The various functions, features, and benefits thereof are described in more detail below.
Theretofore, it is evident that the above discussions between methods of manual and electronic car cleaning apparatus and methods of manual and electronic floor cleaning apparatus for the domestic and industrial markets heretofore known suffer from a number of disadvantages: * People living in apartments or high rise buildings cannot be able to clean their vehicles manually whilst using buckets oiwater or hosepipes.
* A robotic cleaning apparatus deft to operate on its own accord can get ensnared in-between objects and cables in a home environment.
Robotic floor cleaning apparatus for the home markets are rushed traversal or random, besides, they haven't the know-how to see or repeat a task if a portion is left unclean or missed.
Robotic floor cleaning apparatus for the home markets do not sanitize the final or last cleaning mechanism that comes into direct contact with the floor surface being cleaned along their cleaning path of their cleaning operations, and other similar prior art wet cleaning apparatus that incorporate the use of stationary passively fixed squeegees or scraping blades as the final or last cleaning mechanism that makes contact on a surface being cleaned along a cleaning path are known to permit the transmission of dangerous infectious bacterium, fungal and viral elements odours that are left behind a cleaning surface through smearing and dragging stuck or flood in between floor patterns and building expansion joints crevices or grout-lines on floor surfaces.
* Robotic floor cleaning apparatus for the home markets are known to be delicate and inflexibly in communicating with different floor surfaces and objects. For example these robots can spend an excessive period of time perpetually trying finding a way out or to accomplish a task as simple as to get over an electric cable lying on a floor surface that requires cleaning.
* Robotic floor cleaning apparatus for the home markets are characterised by their small and smooth rounded disc shapes. These conical small shaped objects can be a tripping hazard on the floor of the house especially when coupled with their operating random movements and disorientating whirring noise capacities. Thus, these robots can pose as a tripping hazard for the people around the house and especially children and the elderly.
* Robotic floor cleaning apparatus for the borne markets produces high whirring noise amidst emitting and circulate exhausted gases used from the dirty floors being cleaned by the force of the vacuuming port elements. These used gases are expelled from the robots and back into the air in the room. These expelled gases may contajn remnants of unfiltered and agitated dust particulates.
Thus, this had air circulated by the robots can cause discomfort to persons with allergies and bronchial conditions. To add on, disturbed or raised dust particles may contain viral and bacterial elements that can be an additional health hazard. Gaseous emissions by these robots can produce putrid or stale odours to be circulated around the home.
* Robotic floor cleaning apparatus aimed for the home markets are noisy and frustrating to work as they follow a set of rigid predetermined rules, and cannot reverse or skip an unnecessary task unless the whole process is first completed.
* Manual vehicle washing methods are untidy, wet, labour tasking and time consuming exasperating operations.
* Electronic and manual domestic cleaning apparatus that use micro-fibre pads that consist of millions ofhighly absorbent capillary acting micro-fibres that attract dirt, cleaning upholstery and carpets well without the need for chemicals, but on1y with water. However, these cleaning apparatus are incapable of' regenerating We micro-fibre pad on the cleaning head in use, thus, leaving the user with the arduous and messy task of continuously removing the Velcro stuck micro fibre from the flame of the device-where hazards risks such as chemical splashes to the face, eyes or breaking fingernails is achievable due to the force used in pulling the Velcro attached micro fibre, or elastic bands, then rinsing the micro-fibre under a tap of running water-an unnecessary waste of water, then wringing the micro-fibre cloth which again is a tasking as wringing a car washing leather chamois, before reattaching the micro fibre back to the frame of the cleaning apparatus in order to commence cleaning, and it is not long before the whole cycle has to be repeated again. That exercise alone can cost a tot of time, resources and cause to anxiety for the user of this prior art device. Such micro-fibre cleaning apparatus drag dirt and contaminants across a cleaning surface in the same way a conventional mop and bucket or squeegee equipped wet cleaning apparatus does.
Powerful cleaning chemicals used by electronic floor cleaning apparatus which incorporate use of stationary passive doctor-blades and squcyees as the final element in direct contact with the floor being cleaned and since this elements are not cleaned, rinsed or sanitized by any means during a cleaning operation, this elements merely smear, push and drag along un-rinsed residua'-films of corrosive cleaning chemicaLs, odours, bacterium and waste solution. When these used cleaning chemicals dry up on the surfaces, they can be hazardous if inhaled in particulate form.
* Gantry commercial type carwash plants are un-environmental because they consume vast percentages of electrical power and water resources to only clean a single car. Industrial car washing plants are known to use in excess of 200litres of ater to clean a single car.
* During cleaning operations electrical floor deaning apparatus do not automatically clean, sanitize or refresh the drying elements which make final or the last contact with a floor surface that is being cleaned by these devices along a cleaning path.
* Manual methods and devices of vehicle cleaning operaCns consume a lot of water which adds up to higher utility bills.
* Manual vehicle cleaning methods are untidy, labour tasking and time consuming operations, for example, wringing a drying chamois is an operation that is a hard task when carried out by hand especially to anyone with joint disorders like arthritis in the fingers since it involves simultaneously twisting, squeezing and compressing or graspingly wrenching the chamois so as to extract the liquid in order to obtain a desirable degree of drying and shine on a vehicle paintwork. However, it is also difficult to obtain an even degree of dryness of the chamois and consequently that of the vehicle surface being dried. At the same time, manual wringing I. operations by hand require a considerable amount of strength to grip and twist the chamois and can cause muscle cramps and fatigue to the hands, body wrenches and chafing of the hands due to the force exerted and exacted into the joints. Additionally, the wrung-out water finds its way to the clothes or feet of the user. Water splashed on floor surfaces can also pose as a slipping hazard and worse during winter when such spills can become frozen.
Often, when domestic autonomous robotic cleaning ap1iaratus encounter simple difficulties such as blocking of vacuum intake ports or a e*anglement around a cable or strand, e.g., drive gears being partially or fully jammed by, strings, tapes, toys, shoelace or an accumulation of dog hair strands, these robots carry on working thus unwarranted damage is introduced to the primary and secondary chain of components involved, for example, damage from an intermeshing gearwheels to the blowing-up of a drive motor, which adds up to unnecessary repair bills or complete malfunction of the robot.
* Manual vehicle cleaning methods can cause physical ailments due to the laborious tasks of bending, wringing, lifting and scrubbing involved. People with cardiovascular or joint ailments like arthritis cannot clean their vehicles manually.
* Whirring or jet-noise produced by robotic domestic cleaning apparatus run down battery power quickly since the high velocity suction fans dedicate and consume more power ratios for the fans and motors motion than is left for the vital service of suction and dirt agitation.
* Prior art electronic or semi-electronic vehicle bodywork car cleaners have sharp edges or poles that can damage the bodywork and paintwork of a vehicle.
* Gantry commercial type car washes are widely known to provide an elusive deal to customers who have to drive away with water run-off or wet or semi-wet vehicles, whereby when this droplets dry, they leave dried droplet-marks on the surface of the paintwork. Thus, most people carry a chamois in their vehicle glove-box so that they can dry the vehicle paintwork manually, even though they have already paid a charge for this drying service which the gantry carwash plants are incapable to fulfil.
* Gantry commercial type car washes are expensive to use, and because they treat every car as though it were the dirtiest portion of the dirtiest car, even though the car is not very dirty, they inherently causes needless extra paint scratching thus many people have rejected gantry car washers for this reason alone. The scratching or hazi:ig is worst when rotating brushes holds particles such as sand or grits from one en; and then scratches the following cars.
* Since gantry type car washes have to clean vehicles very fast; and since it must be assumed that every car is the dirtiest car, very strong soaps and chemicals (in excessive amounts thereof) must be used to loosen the road-film and other contaminants as well as by the extreme rotating brushes.
Gantry commercial type car washes have a frequent objection to projecting vehicle accessories such as car radio antennae, rear screen wipers, outside mirrors because of the violently-whirling brushes of the gantry car washers.
Gantry commercial car washes are known to commonly leave portions of paintwork areas surrounding 4x4s perched spare-wheels missed or untouched by the cleaning brushes. Protective covers on 4x4 spare wheels are frequently damaged or entirely disconnected from the vehicle-and at the owners cost for repair because owners of this car washing plants deny any responsibility by placing disclaimer warning signs near or on the entrances of their car washing plant.
Manual car cleaning methods using high elocity pressure washer commonly known as pressure washers or jet-washers cannot be used entirely on their own since thin road-film dirt remains on a vehicle's paintwork and cannot be removed without further manual scrubbing work done on the car-surface by sponge, brush, wiping etc. * Using high velocity pressure washers too close to the paintwork being cleaned can rip-off paintwork, destroy plastic installations and decorative skirting tapes and vehicle insignias. Jet washes exacerbate or worsen and enlarge decayed portions of a vehicle's paintwork.
* Nearly all manual surface cleaning operations leave hiatus or interim moments of time between scrubbing, rinsing, wiping or drying. In car cleaning methods this spaces of time vary when using hosepipes, pressure washes or the conventional bucket and sponge. The length of time can be determined by either the size and of the vehicle being washed; the time or distance to get rinsing water; the adequacy of skill or experience of the cleaner; or whether it is cold windy or hot. Since each process has to be completed before another is begun. This hiatus between the process of rinsing and wiping the vehicle is so rnucWoften where scratching of the paintwork occurs since the run-off water suspension film, and within it particulates and impurities suspended therein starts to dry up on the vehicle's paintwork. Rubbing a semi-dry wiping or cleaning material such as a chamois or a flexible silicone blade on the drying-up surface cause friction between the chamois, (or in the case of using a flexible silicone blade) and the vehicle paintwork. Therefore, particulates caught in between the chamois (or along the ridge of the flexible silicone blade) can scratch or graze the paintwork of the vehicle's bodywork. The process can be made worse if a breeze exists or if the sun is bright, and the rinse run-off water dries before the wiping process is fully completed. During very cold wintry days, thin films or sheets of ice can form on a vehicles surface during car cleaning operation. Using heated water at such juncture can cause glass windshield and windows to break. Thus, it is nearly and equally unpleasant to manually attempt to wash a car on hot days of the summer as it is in the cold days of the winter.
People wishing to clean their cars manually during the summer months are presently banned from doing so in some counties in the south east of England. A hose-pipe ban is in force during the summer months and is imposed so that reservoir water is saved from unnecessary depletion.
Gantry type car cleaners continue to operate normally during these summer bans, bearing in mind the vast consumption oiwater in excess of 2001 itres rhat the plants use in order to clean a single car.
* In some countries, criminal laws have been enforced to stop people from washing their vehicles, for example, in Canada, there are laws in some municipalities that aim to conserve water and desist people from manually washing their cars for more than 20 minutes,-which is an extremely inadequate amount of time for even the professional car washer to manually complete washing a car in. In Switzerland, people are not allowed to wash their cars using soap or any other such chemicals.
* During cold spells, gantry commercial type car washing plants are un-usable because the fluid administering pipcs, conduits and nozzles freeze up. Also, attempting to wash a vehicle manually or by using devices like jet washes during cold weather spells transforms water sprayed on a cold vehicle's bodywork into a thin sheet of ic that is very difficult to remove unless by pouring hot water on the vehicle's surface. Pouring hot water on ice stuck on vehicles is known to suddenly expand thus crack glass and other installations.
* Attempting to washing a vehicle during cold winter months cause severe discomfort and numbing especially to the fingers and other parts and joints of the body.
* Gantry car cleaning equipment operate in dark or poorly lit claustrophobic enclosures, the cleaning nature of this plants coupled with vigorous shuddering is not a favourite to most people, and especially young children who tend to get frightened easily.
* Because gantry car cleaning or car washing plants treat every single car as though it were the dirtiest portion of the dirtiest car, even though the car is not very dirty, they inherently cause needless extra paint scratching thus many people have rtjected gantry car washers for this reason alone as they tend to leave arrays ofscratces in the shape ofa bristle filaments commonly known as brush marks. on the vehicle's paint. The scratching or hazing is worst when a rotating brush holds sand or grit from a previous car and then scratches the following cars. Thus, due to the nature of these heavy duty carwash plants, powerful motors, strong detergents, soaps, unyielding industrialized brushes and bristles therewith, vehicles begin to show an array of hair-line or hazy scratches all over their paintwork's lustre only after a few visits to these car washing plants. Thus, hazy brush marks scratches are especially visible on reflective rounded surface areas of the vehicles paintwork causing vehicles to lose their enhanced aesthetic appeal. These machines are expensive to use and are not flexible enough to do the cleaning job of washing and drying a vehicle paintwork well enough for every single different make of vehicle's paintwork that they wash. Moreover, the vigorously rotating industrial brushes are known to break or disjoint vehicle fixtures like wind shield wipers and washer nozzles, outside minors, drip molding, radio antennas, roof-racks, spoilers. 4x4 spare wheel protective covers and relative attachments. These car washing plants are also known to be incompetent in cleaning inwardly and lower inwardly curved lower vehicle body side mouldings. Industrial car washing plants are also known to be nicompetent in drying vehicle bodyworks thoroughly. rinally, and among further disadvantages, they cannot see therelore cannot repeat ajask ifa portion of the painted bodywork is left unclean or untouched.
Robotic floor cleaning devices for the home markets lightweight and cleans the surface lightly thus may not penetrate or dislodge a stubborn dirt or stain sufficiently, it does not get to the edges of corners as it is circulai in shape, it traverses in a random motion and needlessly repeat surfaces or entirely misses targets; and cait be a tripping hazard due to its abrupt haphazard movements and small domed size also, they are noisy due to its high velocity blowing and suction fans and motive drive motors their lightness removes their efficiently in cleaning spot stains that demand robust washing capabilities.
Robotic floor cleaning devices for the home markets possesses miniature mixed reservoir tanks for cleaning and rinsing fluids, thus is limited in the amount of floor surface cleaning scale and range. Also, emulsifying dirt such as dog mud marks and destroying viral and bacterial agents require generous applications ol' cleaning agents.
Robotic floor cleaning devices for the home markets are lightweight robot on the cleaning surface uses a stationary doctor-blade or squeegee type lip as its final or last cleaning component in their under chassis during a cleaning operation along a cleaning path and when it comes across dirt stuck on a floor they hops or skip over it.
High velocity blowing fans in robotic floor cleaning devices and vacuuming ports expel dust via pattern tile gaps, blocked filters and uneven floor surfaces causing discomfort to persons with allergies and bronchial conditions. Disturbed or raised dust particles that may contain viral or bacterial elements can be an additional health hazard.
Wet cleaning devices with stationary doctor blades or squeegee type ridges or lip that is the final or last cleaning component on a surface being cleaned along a cleaning path can cause cross-contamination by transmitting infec1ious microorganisms through carrying, smearing and dragging the germs and bad odours along and across floor surfaces and locations. Such devices do not rinse or wet clean carpet material or the like. Therefore, since the permanently fixed squeegee blade is the final or last cleaning component that makes contact with the cleaning surface along a cleaning path of the cleaning operation as it is continually dragged to pick up waste liquids, it does not rinse or sanitize the cleaning surface which deteriorates the efficiency and hygienic proficiency of the cleaning operation which can further allow for the cross-transmission and spread of microbial elements on a floor surface being cleaned Gantry commercial carwuslies require huge 3-phase 4l5volts electricity mains supply, significant amount of mains water consumption and supply, detailed architectural planning and public consent. Furthermore, gantry corn mercial earwashes require underground petrol/oil/solvent interceptors to public storm or foul water sewers which require considerable excavation and trade effluent agreements with the water boards companies, local government business rates, permanent attendants, high financial invcstmcnt etc. Finally, these machines are not environmentally friendly since a lot of non-renewable energy such as coal and nuclear fuels is spent in order to provide for the high electrical demand needed by these industrial car washing plants.
* Robotic floor cleaning apparatus for the home markets that use squeegee type blades as their final cleaning mechanism that comes into contact with a cleaning surface across a cleaning width scratch, scrape or graze wooden and synthetic designer floor patterns, by dragging along sharp edged jammed obiects such as broken gla.
* Robotic floor cleaning apparatus for the hornc markets that use squeegee type blades as their final cleaning mechanism that comes into contact with a cleaning surface across cleaning width smear grease along floors, also locking it between floor surface crevices, grout-lines and patterns.
* Robotic floor cleaning apparatus aimed at home markets are lightweight on the cleaning surface and possess miniature reservoir tanks for cleaning and rinsing fluids, therefore, they are insubstantial in tackling dirty surfaces that compel robust washing.
* Robotic floor cleaning apparatus aimed at home markets are lightweight on the cleaning surface and possess miniature reservoir tanks for cleaning agents, therefore, they are limited in destroying hazardous viral. fungal and microbial substances that may require extra application of cleaning agents and cleaning severity.
* Robotic floor cleaning apparatus aimed atThome markets are lightweight on the cleaning surface use doctor bladcs or squeegee type blades as their final cleaning mechanism that comes into contact with a cleaning surface across a cleaning width hop-over or skip over debris and contaminants remnants and residues across a cleaning path.
* Robotic floor ereaning apparatus aimed at home markets are lightweight on the cleaning surface and use passive stationary doctor blades or squeegee type blades as their final cleaning mechanism that comes into contact with a cleaning surface across a cleaning width spreading and smearing and streaking contaminants along which may include hazardous viral and bacterium organisms across the surface, and that the contaminants can be further pasted and embedded in between the grain and relief design pattern of tiles and tile crevices or grout-lines between tiles.
* Robotic floor cleaning apparatus aimed at home markets cannot leave cleaning solution on the floor surface for a few minutes to loosen dirt and grease as they traverse across surfaces haphazardly.
* Floor cleaning mops with reilF sponges,ads. wipes or absorbent micro-fibre cloths require the absorbent or wiping element to be consistently manually replaced during or in between a cleaning operation which is a time consuming and wasteful, expensive as it adds to countless rinsing cycles and washing machine cleaning of the refills, frustrating, tedious and laborious to use.
* Floor cleaning mops and micro-fibre mops with refill' sponges and pads expose people's hands and fingers to direct contact with hazardous cleaning chemicals, bleaches and microbial contaminants whenever the refills' need ceaseless manual replenishments or changes.
* Changing refill mops at close range to the face can be perilous due to the hazardous chemical fume emissions and risk of possible chemical splashes, such as bleach to the mouth and eyes during the manual releasing of the refill mops from the frame cleaning head or vice versa. Thus, this demanding refill mops can be fidgety and tedious to work with which can be a recipe for careless episodes when manually constantly changing the micro-fibre or sponge refills, then rinsing them and wringing them belbre ftther reattaching them back to the frame of the cleaning head in order to commence a cleaning operalion.
* Changing refill mops can break fingernails and scratch hands when a user tries to rip the Velcro-microfiber attachment or thoroughly placed microfiber hook attachments on such cleaning heads. Coming into contact with dirt and germs collected from a cleaning surface is both undesirable and unhygienic.
* Although some microfiber and sponge mops have a wringing way done by twisting or forcefully pulling a two-picce lever on the handle boom towards or away from the user. The degree of drying therefore depends on the strength ofthe user-which can be taxing experience. Thus, these types of cleaning mops are not any more different in use or cleaning methodology to the conventional manual bucket and mop cleaning apparatus which, among other disadvantages spreads germs easily across a floor surthce.
* 3ecause microfiber refill mops and spones are treated with a one-off anti-bacterial treatment during manufacture, they depreciate in rapidly efficacy from once they are used, washed, or used Lising, bleach, waler hot above a certain degree, thereby becoming quickly ineffective and unhygienic to use -needing replacement which is a waste of finances to the user as well as exhaustive to the environment by such materials and plastics being disposed to landfill and polluting the air via incineration disposal methods.
* During a manual car cleaning operation, attempting to wring out liquid from a wet slippery chamois can be a muscie-cramping ordeal for the users' hands and fingers.
* During a manual car cleaning operation, constant chamois wringing and wiping rapidly depreciates a cleaning chamois, Synthetic chamois are known to flake off gradually leaving numerous flakes stuck on the surface being cleaned and inside the rinsing water reservoir. This happens because every time they are stored, dried, then used after sometime, they further deprcciate. Thus, the life cycle of synthetic chamois is chort and replacements are expensive.
* Prior art vacuum cleaners are heavy andan easily cause injury to the back as our backs are not designed to be in a mid-stance posture for any amount of time and it is easy to injure a disc, muscle or other soft tissue while hanging over stooped that way for an extended period.
* Prior art vacuum cleaners are heavy and do not, wash and dry surfaces as they vacuum the surface since they arc limited to vacuuming surfaces only, leaving a user with rio option but to user other manual cleaning options. Thus, wet cleaning a surface after using such heavy prior art vacuum cleaners has to be done using additional laborious manual ways using different cleaning apparatuses such as microfiber mops, steamers, bucket and mop and wiping-on-bended-knee, and can be laborious, repetitive, tiresome and back breaking work.
* When one is carrying out most wet manual cleaning operations, laborious tasks such as scrubbing, rinsing and drying can leave a person with a wrenched back, hip or entire body, chaffed fingers and cramped hand muscles due to hard wringing of a wiping material, hazardous exposure of hands to corrosive cleaning agents, etc. F-trtherniorc, manual washing operations are hard tasks when carried out by anyone with joint disorders like arthritis or cardiovascular ailments.
* When one is carrying out most wet manual cleaning operations, to avoid being over preoccupied and caught-out by the rapidly drying surface before a following task of rinsing or drying commences, one has to rush against time depending on such factors as the time of day night and the weather which can determine the rate at which the surface being cleaned dries. In manual car cleaning, hot, warm, windy or cold temperatures affect the surface being cleaned and the drying pace. In indoor cleaning, these drying times may be accelerated by higher indoor temperatures.
* Gantry commercial carwashes require consumption of disproportionate amounts of electrical and water resources to clean a single car, the plants are unecological to biodiversity thru the hazardous chemicals produced. These hazardous ignitable, corrosive and toxic chemicals may include arsenic, barium, cadmium, chromium, lead, mercury, selenium, silver etc, contaminate surface waters, soil and groundwater tables through used cleaning chemical action and hazardous contaminants dislodged from vehicles which sequentially drain into storm drains, forming sludge, leaching into the soils and subsequentlyilow into streams, rivers, lakes and the seas in effect disrupting the cyci ical hydrological, hydrobiological and hydrographical balances, i.e.; eroding and corroding soil and depleting soil nutrients, contamination of ground water tables thru intrusive infiltration, inhibition of the growth of vegetation, water plants and various adverse effects on aquatic and land animals living in or near riverine, lake and to the sea.
While each of the above examples provides manual and electric wet surface cleaning apparatus and articles for washing an extended surface, there is heretofore no teaching of an affordable, easy to use and noncomplex surface cleaning apparatus for applying a cleaning fluid onto a surface and removing the spent liquids in one pass whilst continuously and sufficiently rinsing, sterilizing and drying any extended surface in the home and industrial markets. A need exists in the art for such a device and that need is addressed by the present invention, the various functions, features, and benefits thereof described in more detail herein.
BACKGROUND OF INVENTION-----OBJECA AND ADVAN1'AGES
Accordingly, besides the objects and advantages of the self-regenerating surface cleaning device described in my above patent, several objects and advantages of the present invention are: To provide a surface cleaning device which implements newest designing tools and efficient raw materials and technology thereby molding itself to the benefit of the user in diverse cleaning exercises and needs; and that the cleaning device is simple in design and intuitive to operate, cost effective as it uses fewer parts thus lesser energy consumed; has a reduced cost of manufacture, light weight, quiet to use, reliable, flexible and comfortable to work with; that it is clean and hygienic, safe and odourless to work with, has anti-slip (when wet) ergonomic handles to hold on, and is ecologically sensitive to manufacture.
* To provide a surface cleaning device which is not laborious to use and saves time by doing the task of cleaning a surface in a small amount oltime.
* To provide a surlace cleaning device whii automatically solves or removes the need for human intervention for manually wringing a cleaning material such as a mop or leather chamois by hand and relative tasks of carrying bulky buckets of water.
* To provide a surface cleaning device that is lightweight and dynamic in quickly washing, rinsing and drying surfaces thereby reducing or completely eliminating the needs for cleaning operatives especially in supermarkets, hospitals and large firms the need to carry numerous cleaning equipment such as mops, buckets of liquids and other cleaning accessories and hazardous cleaning products exposed on large wheeled way-blocking trolleys when cleaning or attending to only small spills that may have been caused by accidental breakage of a certain liquid holding bottle in a supermarket.
To provide an surface cleaning device that is lightweight and dynamic to work with, for example, when collection of an accidentally spilt thick or concentrated liquid such as ketchup, mayonnaise, various creams, yogurt and red wine occurs, the cleaning device herein shall collect the thick liquid in one swipe or pass, and without leaving streaks on surfaces; whereas normally, there is involved numerous separak arduous maSual tasks of scooping the thick spilled liquid, before cashing and drying the floor surface. Similarly, squeegee and prior art wet cleaning apparatuses that incorporate squeegee type components only exacerbate the problem by dragging or smearing such thick liquids across a floor surface.
To provide an all-in-one surface cleaning device which shall utilize concealed dynamic multi-acting dirt, grease and debris collecting and surface agitating mechanisms and component that leaves the surface shiny pristine and smear-free.
To provide a surface cleaning device which is a portable drying device that uses softly furrowed foam filled sponges or wool mitts to shampoo and scrub vehicle surfaces by moving in gentle reciprocating and circular motions as opposed to the vigorous conventional one-way rotating brushes associated with gantry car washes and known pole and rotating brush' type car washes that cause scratch damage to vehicle painted surfaces.
To provide a suriace cleaning device which is porLable and scrubs, rinses and dries a vehicle paintwork in a single passing or swipe of the cleaning device, since vehicle paintworks respond best to brilliant streak-less shines after being dried when still cool and wet with rinsing fluid.
To provide a surface cleaning device which possesses a pivotal means for reflex action that adjusts to every curvature of a cleaning surface such as a concave curve, a convex curve, ramps or gradient steps e.g. the intermediate or bordering different surface levels between a raised carpet placed upon a smooth floor surfaces, and between other different textures such as linoleum, laminate, marble, vinyl, hardwood, ceramics etc. To provide a surface cleaning device which is portable and lightweight and automatically scrubs, rinses and dries a surface thus helps a user to avoid the ordeal of being caught out unexpectedly as it is so ollen when one uses prior art wet cleaning apparatus like jet washes, hosepipes, bucket & sponge, mops, refill mops, rotating brush and pole devices etc. Being caught out by a quickly drying cleaning surice before a next or f6tlowing task such as rinsing or drying commences can be frustrating. In such instances, one has to rush fast against time so that the surface being cleaned doesn't dry up before a following task commences. The pace or time taken at which the surface dries up can vary due to a number of dependable factors, such as; the speed at which the surface is being cleaned at; the outdoor or indoor temperature; the amount of cleaning liquid or rinsing liquid that is applied onto the cleaning surface; the texture and hydrophobicity of the surface, and the absorbency of the drying element of the cleaning device. For example when washing the surface of other objects or when manually washing a vehicle paintwork, hot, warm, windy or cold temperatures may affect the drying period due to the resulting temperature of the vehicle's paintwork. When washing the surface of other objects or when manually washing a surface such as a floor while indoors, the drying times may be considerably shorter oraccelerated due to higher indoor temperature. In such cases when the surface being cleaned dries up before the next task commences, the successive tasks of scrubbing, rinsing and drying can become undone. Thus, one has to restart the entire cleaning operation or have to respectively repeat some ckaning steps that had been previously conch ded.
* To provide a surläce cleaning device which can be adapted or have a controllable function that allows a hot cleaning solution on the floor surface for a few minutes to loosen dirt and grease.
* To provide a surface cleaning device which can be arranged or have a controllable function that allows a cleaning solution such as a bird lime neutraliser on a surface of a vehicle being cleaned so that the caked bird dropping are easily dislodged from the surface of a vehicLe being cleaned.
* To provide a surface cleaning device which can be adapted to work in a circular, elliptical, triangular or rectangular cleaning head or chassis in order to reach tight corners and narrow gaps.
* To provide a surface cleaning device which is easy to use and can be used by most people regardless of age group or height. Moreover, the device of the present invention allows people with ailments such as cardiovascular or joints disorders to be able to clean their vehicles and floor surfaces easily and safely.
* To provide a surface cleaning device which is lightweight, silent or quiet during the cleaning operation.
* To provide a surface cleaning device which is lightweight and has easily adjustable telescopic variable height handles to comfortably accommodate people of any height, as prior art vacuum cleaners are static, heavy and can easily cause injury to the spine as our backs are not designed to be in a mid-stance posture whilst swinging from side to side and back and forth for any amount of time as it can easily cause injury to a spinal disc, muscle tissue or other soft tissue and ligaments, agitate and or exacerbate an existing back ailment, while a user hangs over stooped that with their backs acting as the pivot supporting the weight (of heavy prior art vacuum cleaners) in that posture over an extended period.
To provide a surface a lightweight surface cleaning device which vacuums dirt and debris, washes and dries surface in one pass over a cleaning surface, as most prior art vacuum cleaners are heavy and do not, wash and dry surfaces as they vacuum the surface since they are mostly limited to vacuuming surlaccs only, leaving a user with no option but to user other manual cleaning options such as using addilional laborious manuaLays using heavy other different cleaning apparatuses such as microliber mops, steamers, bucket and mop and wiping-on-bendS-knee, which can be a laborious, repetitive, tiresome and back breaking work.
To provide a surface cleaning device which is ergonomic to hold on the hand and fingers. and is soft on the surface of a vehicle's paintwork in order to avoid scratching or denting the paintwork.
To provide a surface cleaning device which is portable light weight cleaning device which scrubs, rinses and dries any surface and such as that of a vehicle in one instance, pass or stroke of the arm.
To provide a surface cleaning device which is portable light weight surface cleaning device that provides broad unhindered cleaning possibilities. For example, vehicle bodyworks shine the best when the paintwork is cool, rinsed and wiped immediately without any periods of intermission between rinsing and drying.
To provide a surface cleaning device whie uses flexible absorbent material that are gentle on the painiwork ol future vehicle delicate pairitworks as oil-based paints are gradually being phased-out, thereby leaving exposed a gap where people can have their cars cleaned without gelting their delicate lacquers scratched by vigorous car plant washes or inflexible vigorous hand wand brush washes.
* To provide a surface cleaning device which is portable tight weight vehicle cleaning device which scrubs, rinses and wipes-dry the paintwork surface of a vehicle in one instance or stroke of the arm.
* To provide a surface cleaning device which is shall present several different cleaning modes by automatic actuation or manually depending on the intensity of dirt on a particular area of a particularly soiled surface e.g. a vehicle paintwork surface being cleaned.
* To provide a surface cleaning device which shall present several different cleaning modes depending on the irflensiiy of dirt or liquid on a particular area, individual room floor profiles or patterns, and to clean into the grain of floor surfaces.
* To provide a surface cleaning device which is not rigidly programmed but is dynamic to a user's varied or specific cleaning needs; has easy ways or switches for controlling quick or slower operations; scrubbing, wiping, spot-cleaning, soap dispensation etc., can be interruptible or programs can be manually actuated and or overridden by the user via choice during a cleaning operation.
To provide a surface cleaning device which has various settings for manually leveraging or have pre-determined cleaning modes of operating functions or buttons choice settings to increase or decrease various (asks of the cleaning device. For example; the cleaning device's surface speed or motion, choosing a left or right or forward or reverse direction, measure of the force of suction against a surface or level of the magnetic adherence of the device on a vertical plane, guidance of the pressure or velocity of the liquid spraying nozzles for rinsing or shampooing a surface, degree ofadherence to a surlhee, wiping material's speed. intensity of the rinsing and drying, particle or debris removal from wiping element dep*nding on the state of the surface being encountered, force of the compression ol' liquid urging mechanism that subsequently aflècts the liquid surface absorption degree of the wiping element thus the duration of time that the surface dries at.
To provide a surface cleaning device which shall preserve and by not dislodging vehicle projecting piece of equipment such as car radio antenna, headlamp wipers, screen wipers, side mirrors etc. To provide a surface cleaning device which removes thin road-film from a vehicle paintwork surface in one operation since current market pressure washers or jet-washers are incapable of doing so without a manual intervention of rubbing.
To provide a surface cleaning device which scrubs, rinses and wipes-dry the surface of a vehicle surface in on single stroke operation i.e. without leaving any interim spaces of time between * scrubbing, rinsing and drying the paintwork surface.
To provide a surftice eleaningdevice which can he used easily and safely by people living in high rise apartments or houses considerably away from communal car parking places like basements.
It can be very difficult or impossible for people living in these situations to use a hosepipe or carry buckets of water up and down staircases in a quest to clean their vehicles.
To provide a surface cleaning device which provides peace of mind where users can use the device to clean their vehicles during the hot summer months without worrying about breaking imposed county council taws such as current hosepipe bans in the south east of England.
* To provide a surface cleaning device which when used in the car cleaning aspect of this disclosure is art ecological surface cleaning device that uses minimal electrical power and water resources to clean entire vehicle bodywork as compared to gantry type carwashes and hosepipes which use a vast amount olwaterjust and electricity to clean a sing vehicle. Additionally, a cleaning device * that can be conligured to recharge a lithiuw battery via solar power and scavenging for power via kinetic surface contact friction during operation by a user.
To provide a surface cleaning device which can be used safely and easily by people when cleaning their cars during cold spells of the weather as liquid delivery pipes of gantry car washing plants freeze up and are normally shut down during such times. The present invention described further herein allows the hands and fingers of the cleaning device's user to remain warm and dry.
There is no addition to the risks normally associated with car washing like spraying or splashing water to the clothes or feet of the user. More importantly, the risk of slipping on frozen water whilst using the present invention is highly limited since the cleaning device guards against, and takes back the cleaning fluids that are used during the cleaning operation.
To provide a surface cleaning device which ensures no cleaning liquid spill and splash from the cleaning device during operation on a vertical plane surface such as when washing the vertical plane or side of a ear.
To provide a surface cleaning device which is economical to manufacture and sustainable and that adapts or is addable into the prior art produtt and technological theme, and that is easier to use and appealing to look at and enticing and inspiring to use.
To provide a surface cleaning device which uses a minima: amount of domestic electricity, consumes a minute amount of water resource to clean a car and is lightweight, well balanced and easy to use.
* To provide a surface cleaning device which eliminates the prospects of cross-contaminations and transmissions of microbial elements through its isolation and storing chambers and further disposing off the used cleaning fluids and collected contaminants therein, an separate and segregated manner such that as the drying element is automatically and continually replenished, sterilized and regenerated to constantly clean the surface being washed sufficiently.
* To provide a surface cleaning device which is portable and scrubs, rinses and dries any floor surface in a single pass using a constantly regenerated cleaning component of the cleaning device that rubs, absorbs and shines the floor at the same time, leaving the surface free from any spent liquids which damage synthetic and natural flooring as is common with contemporary or prior art wet cleaning devices that use passive and stationary squcegees to drag streaks of waste materials across a cleaning surface inevitably sealing floor tile crevices and tile relief design features with contaminant muck and hazardous microbial growth therein.
* To provide a surface cleaning device which does not use permanently fixed doctor-blades or squeegees as the final or last cleaning component to come into contact with a cleaning surface across a cleaning width as it is common with prior art surface cleaning apparatus that incorporate or have doctor-blades or squeegee as their final or last cleaning component across a cleaning width to conic into final or last contact with the surface being cleaned, thus leaving spread out or smeaT-dragged hazardous contaminants, used cleaning chemicals and bacterium residues that further contaminate floor surfaces supposedly being cleaned.
To provide a surface cleaning device which has a capacity to collect or pick up, identify, isolate and destroy harmful bacterium and viral substances such as multidrug resistant elostridiums and staphylococci such as C-Difficile, MRSA, urinary tract bacterium, viral agents, coliform, faecal etc., bacteria suspended in liquids or on biofilni coluny on the surface being cleaned whilst simultaneously sterilizing the cleaning coniponent so that the cycle of the cleaning operation is coiitintied smoothly and efficiently without eessations upon the surface being cleaned while also guaranteeing a continuous supply of a steritised cleaning element that gets in contact upon the surface being cleaned and is the last or final cleaning component that makes final contact with the cleaning surface by the cleaning device, thereby leaving behind a safe and sterile surface.
To provide a surface cleaning device which utilizes a cleaning component that moves perpendicular to the direction of the cleaning device so that different textures and grains of the cleaning surface are thoroughly penetrated by the cleaning component avoiding prior art shortcomings of wet cleaning apparatus where contaminants, dirt, debris, grease and germs are smeared and dragged from one room to another as such prior art apparatus employ use of a rigid passive stationary squeegee or scraping element that is fixed crosswise and moves in contact with a cleaning surface at a direction parallel to the direction of the prior art cleaning apparatus thus dragging contaminants around.
A health hazard is common with conventinal cleaning apparatuses and widely used cleaning methodology known to pose an immense risk in hospitals, laboratories and case operating rooms or theatres, children's nurseries and kindergartens, senior people's nursing homes, holiday cruise ships liners. food processing facilities and food preparation plants, eatery facilities, kitchens in domestic homes, supermarkets and lavatories where cleaning articles used for wet moping and drying floors can carry and transfer dangerous germs from place to place. Dirty and greasy mops and squcegees can spread contamination across floor surfaces. For example, Salmonella which causes food poisoning and known to stay alive on hard surfaces for over 24 hours, arid other highly persistent and virulent multidrug resistant pathogens or drug-resistant microbes commonly known as superbugs, such as methicillin-resistant and methicillin-susceptible staphylococcus commonly known as MRSA and MSSA, and clostridium such as C.Difficile can be easily spread via wet cleaning of floors and kitchen table tops and other sanitary environments. Emerging new viruses such as influenza type A-Hi NI is known to live on hard surfaces for considerable lengths of time. Discussed further below is a more detailed section dedicated to a broader microbiological aspect, scope and potential advantages of the present invention's disclosed herein regarding the matter of human health, cleaner surfaces and surface cleaning. Another recent addition in the electrical wet floor cleaning apparatuses in the home are the use of miniature battery driven autonomous trip-hazard robots. Other similar prior art wet cleaning apparatus that incorporate the use of such passive and stationary fixed squeegees or scraping blade as the final or last cleaning mechanism that makes contact on a surface being cleaned along a cleaning path are known to permit the transmission of dangerous infectious bacterium, fungal and viral elements odours that are left behind a cleaning surface through smearing and dragging stuck or flood in between floor patterns and building expansion joints crevices or grout-lines on floor surfaces.
Dangerous bacterium and fungal elements such as 13-coil, influenza type A MINI. rhinovirus, rotavirus, norovirus, multidrug resistant staphylococcal MRSA and MSSA, C-Difficiie, salmonella respiratory syncytial virus, athletes foot fungus, campylobacter etc., can be smear-spread or carried from one location to another, for example, from ward-to-ward, room-to-room, building-to-building in schools, hospitals, laboratories, malls, food processing plants etc. Besides spreading dangerous microbes, these prior art wet cleaning apparatus that incorporate the use of stationary, cavity unyielding passively fixed squeegees or scraping blades as the final or last cleaning mechanism that makes contact with a surface. being cleaned 1ong the cleaning width's path of these devices leave streaks or smears contaminants such as particulates of dirt, odours, bacteria and harsh un-rinsed cleaning chemicals that are dragged across the surfaces from room to room and premises to premises.
Such occurrences can be a risk to young children who are at closer proximities with floor surfaces as they tend to crawl and roll on the floor. The use of stationary passive doctor-blades or squeegees ridges on wet floor surface cleaning apparatus drag or smear-spread dangerous germs and bacterium like C-Difficile, salmonella, and used cleaning chemicals, harmful chemical odours and their dried chemical particulates around home floors which can be hazardous to young children who tend to crawl and roll on the floors. Like most conventional cleaning implements, microfiber refill mops and robots smear-transmit or carry hazardous microbes across floor surfaces and from one room to another in the same way archaic conventional bucket and mop method does.

Biodiversity is crucial to safeguard life on earth. Thus, a fundamental advantage concerning environmental protection is that the self-regenerating surface cleaning device shall help to conserve the environment and natural resources. For instance, there are over 100 billion cleansing agent containers worldwide that end up in landfill annually. Also, the present invention disclosed herein shall help reduce the need for people to frequently use disposable paperelothes such as kitchen paper towels and related products, thus saving the rapidly depleting natural resources such as indigenous trees thereby reducing the geornorphological domino effect:ausedby tree felling and subsequent vast carbon Footprint produced during the Felling p such and other trees, and thru to manufacturing the paper cloths and tissues, and transportation to retail and domestic markets or other premises. The Carbon l'rust and Forest Stewardship Council estimate that manufacturing a disposable 2ply paper cloth sheet produces at least 2iigrarns of carbon. A single role has an average of 250-330 sheets.
Finally, four billion trees worldwide are cut down each year for paper. The environn-iental impact according to the United Stales of America's Toxic Release Inventory report published by the Environmental Protection Agency say paper making plants are among the worst contaminators to the air, water and land of any other industry in the USA. There are similar statistics provided by the Woridwatch Institute for the rest of the world as each year millions of tonnes of highly toxic chemicals such as, hydrochloric acid, chlorine dioxide, methanol, formaldehyde, and toluene are released into the air and water and land from paper making plants around the world, further destroying our biosphere's cyclical hydrological, hydrobiologica and hydrographical balances.
Finally, by reducing or eliminating the frequency at which washable kitchen clothes, micro-fibre floor type cleaning clothes and household surface cleaning clothes are washed in the washing machine that require high temperature settings, shall help to reduce carbon emission at the electricity producing coal power stations. -Accordingly. the basic representation of the present invention of the self-regenerating surface cleaning device disclosed herein relales to a cleaning device for any dry and wet cleaning or washing operation being performed on any extended surface or object.
it is acknowledged that there are mainly three fuudarnental stages carried out in a washing operation; (I) Scrubbing-whereby a detergent is mixed with a cleaning liquid e.g. water to form a cleaning fluid that is used in combination with a scrubbing component such as a sponge in order to loosen and dislodge dirt from a surface being cleaned, then (ii) Rinsing of the scrubbed surface is carried out using a rinsing liquid such as clean water in order to loosen and wash away released contaminants from a surface being cleaned, then (iii) Drying stage whereby the remnants of the rinsing liquid are removed from the cleaned surface by wiping or air drying, leaving the surface in substantially dry and pristine state. When washing extended surfaces one disadvantage of washing or cleaning extended surfaces like table tops, floor surfaces, windows, walls, vehicles paintworks, are the tedious and repetitive time consuming tasks involved. -Another disadvantage is that these main three steps of washing, that is, scrubbing, rinsing and drying, have to be done one at a time. Thus a major disadvantage during the carrying of these three steps of washing is the hiatus or interval gap period of time between scrubbing, rinsing and drying. During these intervening periods oftime, the cleaning fluid being utilized during cleaning is likely to dry up against the surface being cleaned. Thus, cleaning fluid plus dislodged contaminants drying and getting stuck on the surface being cleaned can put the entire successive washing steps of the cleaning operation into shambles. Therefore, when cleaning a vehicle bodywork or floor surface manually, it is essential to bear in mind about the time limit or intervening period of time between the three steps of scrubbing, rinsing and drying in order to avoid them being left apart for too long so that the dirty or waste liquid dries upon the surface.
Thus, it is notable that there remains a lasting need for an extended surface washing device which can automatically and instantaneously perform the three key cleaning steps of scrubbing, rinsing and drying. An added benefit of amalgamating Hi; technology disclosed herein of the self-regenerating surface cleaning device to the prior art cleaning apparatus and methods, is that numerous manual problematical steps and extra tasks involved in cleaning extended surfaces would he avoided altogether.
More objects and advantages are to provide; a portable self-regenerating surface cleaning device which is stylish, cost effective, has completeness of features and is ergonomic to hold and easy to use, has intuitive and interactive settings and capabilities, is lightweight, conveniently and safe for most age groups to use regardless of height and is ecologically sensitive to manufacture, * a portable surface cleaning device that is lightweight and has cordless options, reliable to use, store and transport, * a portable surFace cleaning device which as a ratio to consume small proportions of electric and fluid supply e.g. water and translating or rnaxiniising that small ratio of resources in order to sufficiently clean large scaled surface areas in comparison to the resources used, which is in opposition to prior art manual and electric wet surface cleaning apparatus which have prevalence in consuming disproportionately large amounts of fluid supply e.g. water and electrical power resources to clean a small fraction or portion of a cleaning surface such as a floor or car, * a portable surface cleaning device which maximally employs volume within an enclosure by way of using a watertight collapsible integrated liquid container with separate collapsible-reciprocation pockets of waste liquid and cleaning fluid as the liquids are being used within the chassis of the device.
* a portable surface cleaning device which possesses optional automatic current oscillation transformers or transient, AC, DC. current transfer function that conveniently scavenges by redirecting and alternating sources of electrical power such as solar power, vibrations, turbine allied forces to rechargeable battery poer modules for low powered-high output transitory alternating currcnt and direct current motors, * a portable surface cleaning device which has the capacity to reuse or recycle used waste fluids such as water and detergents, a portable surface cleaning device (that is fully recyclable) which is inexpensive to produce and that uses recyclable and biodegradable pas components and materials to manufacture. Also, the disclosure of this devic&s cleaning technology can be an additional improvement to the existing designs of the vacuum cleaner heads, specifically by provision of the instantaneous washing and drying capabilities described herein, Finally, to provide a portable self-regenerating surface cleaning device which uses more recycled and less raw materials and that aims to produce more performance using less electrical energy by employing modern more efficient motors and hermetically sealed oiled gear energy exchange units fora more effective, quiet, energy saving device, to createjobs that improve overall energy efficiency and utilize renewable resources. One future example about the energy saving aspect in the manufacturing of cleaning appliances was reported in the Sunday Express Newspaper on the J2Eh September 2010 (page. I 5) and titled EC steals vacuums of suck', where European Commission officials are urging governments to cut the electrical power intake of all vacuum cleaners being manufactured in the future to a quarter of the current power ratings so as to save electrical energy.
This implication would rnate all vacuum cleaners of the future less efficient itt cleaning all types of surfaces and a haiard to allergy and asthma sufferers.
Still, further objects and advantages will become apparent from a consideration of the ensuing
description and drawings.
The cleaning device according to the present invention addresses the disadvantages of the prior art wet and dry cleaning apparatus by providing an entirely self-contained washing device which combines scrubbing, rinsing and drying of any extended surface by passing it over the surface once, leaving the surface in a clean and substantially dry.
Therefore, primary objective of this patent disclosure is to unveil and provide the public of a novel convenient, lightweight, easy to use cleaning implement that has the capability to self-regenerate its surface cleaning component while also screening germs found from the surface being cleaned by the cleaning implement thereby enhancing heir wellbeing. Another objective of establishing this cleaning implement is so that it may become blended into or absorbed into, or flexibly amalgamated into vast array of current or prior all manual and electric wet and dry cleaning apparatuses and technologies thereof. However, the cleaning implement disclosed herein may be established as an independent cleaning device having capacity to collect dirt and debris from the cleaning surface or vacuuming, surface liquid collecting and surface drying cleaning device which can be manufactured and operated independently, molded and having existing prior art cleaning technologies installed thereon, such as; brushing, scrubbing, washing, steaming and vacuum operating interdependently, alongside, within one or more cleaning regions separated within on the cleaning head, wherein also, the self-regenerating surface cleaning device described herein may be included thereon, so that one or more other cleaning components mentioned above may be positioned to operate adequately in a -ft single cleaning head separated within respective cleaning regions that may successively loosen dirt, collect particles or debris, perform scrubbing, rinsing and then drying the surface with the self-regenerating surface cleaning device disclosed herein, leaving the surface in a substantially dry and clean state, which also is hygienically enhanced with the microbial screening aspect worldng separately and in conjunction with the self-regenerating surface cleaning device disclosed in this
patent disclosure.
The present invention overcomes the problems cited in the prior art by providing a low cost cleaning device affordable for home use and capable of wet cleaning floors of different textures without manually changing the cleaning head as the self-regenerating surface cleaning device automatically regenerates the cleaning component used by the self-regenerating surface cleaning device to clean the dirty surface. In particular, a self-contained and self-sufficient cleaning device continuously performs a self-regenerating cleaning cycle on the cleaning component making final or last contact with a cleaning surface along a cleaning width, thereby transforming dirty and or wet surface into a substantially clean and dry state; and the regeneration of the cleaning component done via a cyclical nonstop process comparable to the general method of cleaning any object.
Further, as the self-regenerating surface cleaning device continuously restores the last cleaning component that comes into final or last contact with the surface being cleaned, overcoming setbacks which prior art wet and dry cleaning apparatuses possess as they seldom regenerate, replenish or sterilize their final cleaning component coming last in contact with the surface being cleaned along the cleaning widths of prior art cleaning devices during operation.
Thus, the sell-regenerating surface cleaning device in this patent brings forth notice (to existing technology of wet and dry cleaning apparatuses) of a surface cleaning head which continuously regenerates the cleaning component coming into contact with the cleaning surface.
Hence, it shall be taken into account that the self-regenerating surface cleaning device may also be configured to have other separate successive cleaning regions arranged systematically and to operate in stages or adec1Llateiy otherwise along the under chassis or undercarriage of a cleaning head in contact or facing a cleaning surface, and with cleaning components configured to follow the progressive universal method of washing an object (or however steps preferred yet to attaining the desired goal to clean and leave dry the surface), that is, (I) scrubbing, (ii) rinsing and, (iii) drying a surface by moving the cleaning device across the cleaning surface. These stages may operate simultaneousLy, or separately-one after the other depending on users cleaning choice settings or by actuating certain automatic cleaning cycles. -Therefore the cleaning device may have a first cleaning section configured to loosen dirt or collect particles by suction, and then followed by cleaning components that perform the tasks of scrubbing the surface whilst also applying a cleaning fluid.
The cleaning device may also have a following or second cleaning section with cleaning components configured to rinse and dry the surface being cleaned by the cleaning device disclosed herein.
However, cleaning regions above can be rearranged in a manner that makes them intercalate or come before one another in a manner other than described above, e.g. a vacuuming opening surrounded by the self-regenerating surface cleaning element revolving around the periphery of the underside of the cleaning head in contact with object surface wherein the same vacuum opening branches (or interposed) to fluidly join with another cleaning component in another cleaning section so as to evacuate substances therein, for example. from a plenum module wherein the cleaning element passes through for regeneration. Thus, the cleaning components may intercalate one another in a certain underside cleaning head arrangement of the continuously self-regenerating surface cleaning element of the self-regenerating surIhce cleaning de4ic.e disclosed herein may be configured to operate inconjunction and side by sided with any other cleaning sections described above, or as part of a combination of either one of the above mentioned surface cleaning configurations, built-in a single underside structure of a cleaning head. For example, the cleaning head may have elements placed such that; a suction particle collector mouth operating in conjunction and adjacent to the continuously self-regenerating surface cleaning element; a surface object scrubbing component operating in conjunction and adjacent to the continuously self-regenerating surface cleaning element; a surface object rinsing element operating in conjunction and adjacent to the continuously self-regenerating surface cleaning element; a surface object steaming element operating in conjunction and adjacent to a the continuously self-regenerating surface cleaning element; a high velocity liquid-jet ejector operating in conjunction and adjacent to the continuously self-regenerating surface cleaning element; a microbial screening device operating in conjunction and adjacent to the continuously self-regenerating surface cleaning element;a high velocity steam-jet operating in conjunction and adjacent to the continuously self-regenerating surface cleai.ing element; a sterilizing lamp operating adjacent to the continuously self-regenerating surface cleaning element; one or more self-regenerating surface cleaning elements working side by side on a single undercarriage of a cleaning device, and etcetera. Thus it may be noted that a combination of various different arrangements and steps of separate cleaning components disclosed above may be implemented within the boundaries of this disclosure for the purpose of leaving a previously dirty surface transformed into substantially clean and dry state by use of passing the self-regenerating surface cleaning device at least once over the cleaning surface.
Thus, in accordance with the present invention, there is provided an underside of a cleaning head for the self-regenerating surface cleaning device that can be easily and reliably handled in cleaning an extended surface without the need for manual intervention or need to manually change cleaning head attachments or ancillary cleaning accessories to the underside or cleaning face of the cleaning device, when for example, in order to change or replace a microfiber cleaning pad attachment during a cleaning operation, or when using prior art vacuum clean:rs which come with extra crevice tools,
A
upholstery tools and different floor ancillary tools for manually attaching to their cleaning heads during operation.
Thereto, according to the invention, there is provided a most basic arrangement for the cleaning components of the cleaning head of the seltregenerating surface cleaning device chat has a cleaning element which continuously collects waste liquids and contaminants from a cleaning surface before a regenerating or rejuvenation method and process cycle is performed on the cleaning element, thereby continuously leaving the dirty surface in a substantially clean and dry state by passing the cleaning device once across a cleaning surface.
Meanwhile, the exterior presentation of the self-regenerating surface cleaning device can be of any shape, size or scale in magnitude so long as it is adequate in housing all the cleaning device components and workings within the support structure, safely and securely when being operated by a user, and to thoroughly perform the required task of cleaning any extended surfaces of different textures as required by the user, leaving the cleaned surface in a substantially dry and hygienic state that is best anticipated by a user, is the object of this patent disclosure herein. Moreover, with intent lbr additional aesthetical appeal, the exterior presentation of the cleaning device may have shapely flowing forms that produce appealing and practical designs. For example, smoothened colourfully mouldcd edges of triangular. rectangular. circular elliptical or squarely blended shapes can be used to cover the support structure's housing working elements of the self-regenerating surface cleaning device. Besides, more than one shape and colour may be used in a single cleaning device, for example, a shape derived from the blending of an ellipse and a box with rounded or curved corners; a shape derived from the blending of a cylindrical and squarely shape and etcetera, with lesser panelling arid sectional lock-in crevices that tend to break or divide the aesthetic flow of appearance.
The exterior covering material is ideally recyclable and maybe derived but not limited to plastics and allied rubbers, and resins. The cleaning device may have an exterior covering ideally made from a mixture of opaque, transparent and translucent windows, and other pans with surfaces of different rhythmic colour, patterns and or textural compositions, choosing lightweight recyclable materials without compromising strength. In one dynamic aspect of the exterior design of the cleaning device, the opacity of the windows may be configured in such a way that some of the internal workings of the cleaning device e.g. gear cogs and flowing of liquids is visible or partially visible. High density plastics and rubber resins may be derivable from recycled pellets, dyed liquefied extruded and or injected into replica moulds of the exterior covers and the support structure. Preferably, the exterior presentation of the cleaning device is part oIthe support structural body; that is, the main structure of the cleaning device may he a monocoque structure wherewith the body and frame are integrated so that the external panels or cowling body portions exterior to the cleaning device are designed or contoured aesthetically while same portions in the opposite interior inside of the cleaning device are moulded to fit with precision within non/cc and crannies' or are meticulously contoured to conform to space available in support structure so as to house on-board cleaning components and various other workings of the cleaning device safely and without causing vibrations, overheating, scalding, and noise while in use for a short or prolonged period. That is, a cleaning device designed while hearing in mind selection of readily available raw materials which are environmentally obtained, readily available from recyclable sources, durable and lightweight yet strong for the primary and substructures and other typical structural loading and environmental considerations such as; Ecologically producing definite manufacturing ready parts or comprehensive and accurate digital prototypes prior to manufacture so as to reduce time to market; optimize materiais such as plastic part designs during the design phase thereby reducing their exposure to costly tooling changes and subsequent carbonic emissions emitted during the production of such unwanted discrepancies.
Panelling assemblies that fit adequately with dampng and having tolerances where multiple plastic parts and other supporting material have to fit together. so as to reduce resonance, noise that causes vibrations and gradual buckling during use due to repetitive strain and stresses over time causing amplitude, aging, fatigue, crack groth and malfunction.
* Monocoque structure that shields the inner workings of the cleaning device and shall not disintegrate on impact e.g. a drop or become too hot during running, and can run for a long time.
* Has ergonomic handles to eliminate hand and finger pressures fatigue and electromagnetism.
* Has adequate sealing contact pressure (hermetically sealed) that protects the inner workings of the cleaning device from becoming or accumulating debris such as dust, sand. water that can hamper the electrical and gear components.
* I-las materials that are lightweight, strong and have a low environmental impact without * compromising the power of performance thereby manufacturing a cleaning device that has a low carbonic footprint. A * Has an automatic or manual switch for green' working option where battery power salvaged from free rolling micro dynamos is reserved in batteries and the battery power is used automatically(or manually actuate) instead of using AC electrical power and without interrupting the workings of the cleaning device during use.
* Has adequate watertight sealing contact pressure for casing seals in certain versions of the cleaning device herein that are palm-sized (small as a computer mouse is) and may be constantly carried in pockets or handbags, and also for all other workings and sealed components and parts of many aspects of the cleaning device described herein.
* Hermetically sealing of components working under pressure allows adequate cooling of such components that may need to remain dry, clean and or greased to work optimally.
* Long term use of the cleaning device-4n elevated temperatures during daytime or night time and having long product lifecycle.
An advantage of some of the aspects above is saving on high initial tooling expenditures thru avoidance ofmilling several separate assembly parts. Silicone and similar rubbers and or epoxy resins so may be used for the exterior of the cleaning device for comfortable added compressible fee) to the hands and as a protection for a surface such as vehicle paintwork being cleaned using the self-regenerating surface cleaning device. To reduce environmental impact, recycled pellets of rubbers and such resins may be resin moulded and gauged to make enhanced anti-slip ergonomic hand grips ideal for all age-groups. The cleaning device may also have an interactive and intuitive orderly and neat, uncluttered user input element and or display touch-screen for quick access to the most popular cleaning functions and features or for a user to freshly setup or customize a new cleaning function or cycle operation order on the cleaning device. The basic software to run the cleaning device may be preinstalled on the operating system of the cleaning device during manufacture. However, after purchase of the cleaning device by a user, additional software upgrades may be installed via downloadable methods when available from the central-hub, and sent to the cleaning device via cable connections from a computerised device such as mobile phonc or personal computer or the upgrade information may be directly downloaded wirelessly to the cleaning device.
The cleaning device also has naturally conveniently positioned knobs and simplified control buttons aimed To make housekeeping and car washing, a more attractive, calming, communal, socially harntonising and pleasant chore for adults and children alike. One object of the above aspect of dynamic exterior design of the cleaning device is to positively impart interest or mental inspiration and imagination to the younger generation, also encouraging the children for the need to help parents and guardians in everyday household chores.
Theretofore, the arrangement of the cleaning components and workings of the cleaning device disclosed herein in relation to the surface being cleaned are arranged transverse to the forward and aft direction the cleaning device travels at during a cleaning operation on a cleaning surface, so as to achieve the widest coverage or footage of the cleaning width by the cleaning device across a cleaning surface during a scrubbing, rinsing and drying exercise or cleaning cycle. However it may not always be possible for every individual user to follow the main or rudimentary successive cleaning steps above, since different cleaning stains require different c(eaning approaches which makes understandable that the cleaning device has inbuilt different dynamic modes or operational settings that can be manually actuuted and interrupte& (br particular types of stains, spot stains, general dirt and varying or fluctuating texRires of the cleaning surface; the composition of a particular stain that need removing, and for how long a time the stain has been stuck on a certain surface; whether stains are oily for example in kitchen surfaces etc. Thus, when dealing with a sudden dilemma such as baby spilling a liquid, it may be possible to skip one or more cleaning steps of the cleaning device without reducing the cleaning device's cleaning efficacy since the cleaning device has a diverse and flexible user input element or user-programme input that can be manually or automatically actuated and or interrupted for choice for cleaning different stains, liquids and surface textures, whether during a full pre-planned cleaning exercise or suddenly when only a small portion of, say, a carpet needs to be quickly cleaned of a rapid staining spilt liquid before the liquid is absorbed or dried upon the carpet causing a mark to left on the carpet, upholstery, coffee table etc. Thereto, for the purpose of satisfactorily elucidating as much as possible the cleaning components and relation to the overall support structure of the cleaning device, and that of the surface being cleaned, the description in this patent disclosure shalt focus to an overall basic layout of such elements in relation to the forward, aft and transverse direction or oncnlation, so that it is inure understood how the cleaning components of the sell-regenerating surface cleaning deviceshall perform the washing and cleaning methods and processes generally concluded with the drying stage of a cleaning surface during a cleaning or washing cycle of the cleaning device which may be generally preceded successively or non-successively by an operation of vacuuming, scrubbing and a rinsing stage upon the surface being cleaned using the cleaning device in this patent disclosure.
In one aspect, the invention relates to a surface cleaning device for cleaning any extended surface by continuously regenerating a surface cleaning and drying material for collecting waste liquid from a cleaning surface and the support structure of the surface cleaning device being defined by a fore-aft axis and a perpendicular transverse axis, and may have a preceding or initial first cleaning section with cleaning components configured to collect lose particles dirt and debris from a cleaning surface across a cleaning width, the cleaning width being disposed generally parallel with the transverse axis when moving the self-regenerating surface cleaning device in a forward or backward direction along the fore-aU axis, so that cleaning componenis in the first cleaning section and the second cleaning section of the cleaning device may operate inlheir separate progressive successive steps in unison to leave the surface in a clean and dry state when the cleaningdevicc is passed once over a surface being cleaned.
DESCRIPT1ON OF THE PREFERRED EMBODIMENT(S) According to the present invention, there is provided a self-regenerating surface cleaning device comprising; a chassis, a liquid urging means and a cleaning element, and the cleaning element adapted to clean a surface while being continuously regenerated by the liquid urging means within chassis of the self-regenerating cleaning device.
The chassis of the selttregenerating surface cleaning device, or in short, the cleaning device houses cleaning components which enable the cleaning device to perform cleaning operations and tasks upon a surface being cteaned using the cleaning device by a user. The chassis of the cleaning device may include one or more parts moulded to form the exterior and structural elements of the cleaning device, and the same parts being integrally nioulded,and contoured to form intricate interior parts of the cleaning devce so that the part serves as chassis structure and as well as the exterior.
The chassis of the cleaning device may include a first cleaning region and a second cleaning region; wherein the first cleaning region may comprise cleaning components arranged to collect loose particulates and debris from a cleaning surface across a cleaning width, whilst the second cleaning region may comprise cleaning components arranged to collect spent cleaning fluid from a cleaning surface. The cleaning components in the first cleaning region and the second cleaning region of the cleaning device are artanged generally transverse to the forward and or backward direction of the front and back of the chassis, so as to gain maximum cleaning width across a cleaning surface or cleaning path when moving the chassis ofthe cleaning device in a forward and or backward direction.
Preferably, the structural shape of the chassis is squarely with rounded edges. However, the structural shape of the chassis can be circular, triangular, oval, elliptical, oblong, or a mixture of one or more shapes such as an ellipse and a rectangle, a cylindrical shape blended upon a squarely shape.
ihe cleaning components of the first cleaning region may utilize a vacuuming pod disposed on one or more peripheral transverse, or perpendicular edge of the cle'aiing device and configured to suction up loose particles and debris from a cleaning sirface, The cleaning components of the first cleaning region may also utilize brushes to sweep the loose particulates into a receptacle or otherwise remove the loose particulates and debris from a cleaning surface. The first cleaning region may also carry a second cleaning component arranged to apply a cleaning fluid onto the surface. The first cleaning region may also include cleaning components configured to scrub the cleaning surface.
The cleaning components of the second cleaning region may include a cleaning component configured to collecting spent cleaning fluid from the cleaning surface. The cleaning component for collecting spent cleaning fluid from the second cleaning region may utilize at least one cleaning element. Preferably. the cleaning element is an absorbent resilient flexible material having at least one face exposed to be in contact with surface or object being cleaned using the cleaning device as described herein. The chassis of' the cleaning device is provided with at least one liquid urging means.
The liquid urging means removes spent waste liquid from the cleaning element. Preferably, the cleaning elemeni is positioned attached to the second cleaning region. The spent cleaning fluid is a waste mixture comprising spent clean fiui&rTnsing fluid and contaminant dirt and debris dislodged from the cleaning surthce and suspended or otherwise held therein. The second cleaning region may also include a cleaning component configured to applying a fluid onto the surface being cleaned. The second cleaning region may also include a cleaning component configured to applying a fluid onto the cleaning element. In some embodiments, the cleaning element may be attached to the first cleaning region or second cleaning region.
Preferably, chassis is provided with at least one or more liquid urging means; and the liquid urging means comprising at least one or more rolling elements; and the rolling elements positioned within at least one or more liquid catchment means enclosure module; the rolling elements rotatably mounted in the liquid catchment means enclosure module; means for urging the rolling elements together towards a position in which the surfaces of the rolling elements would make mutual contact along their respective lengths; means for rotating at least one of the rolling elements so that the cleaning element nay be passed between the rolling elements as they are rotated; and the cleaning element having the properties of a permeable, i1exibkbsorptive and resilient body. Preferably, the cleaning element is an absorbent resilient material that is flexible and can be repeatedly compressed, bent and stretched without fracturing such, such as any organic or synthetic spongy material, however, the cleaning element can consist ot' any other absorbent flexible material, and or any other absorbent non-flexible material such as, woo!, mitts, leather, micro-fibre pads, sponges, natural biodegradable cellulose, synthetic cellulose, foam, cotton, various impregnated or laminated strands of fibrous materials, PVA or polyvinyl alcohol, various permeate materials of synthetic or non-synthetic backgrounds, polyurethane foam, vinyl acetate foam, moqquette fabric, cardboard, paper etc. Preferably, the rolling elements are cylindrical and are arranged with their axes in parallel and are preferably urged into mutual contact-Thus the rolling elements may comprise a rigid core coated with a layer of resilient material and preferably have spindles at each end, each spindle being journalled and supported in a bearing, the bearings being urged together by a springy or resilient means so that the rolling elements are continuously urged towards each other. Preferably, one of the rolling element is operalively connected to a drive means whereby the rohing element is mechanically rotated. The other rolling element may also he connected b'j gear arrangement, a chain or belt so that both rolling elements arc driven. This would, of course, normally be occurring at the same time as the cleaning element passes between the rolling elements. The cleaning element or the absorbent resilient flexible material is compressible in-between the compacting forces of the rolling elements to approximately 10% of its original body thickness before the compression occurs. Preferably, the rolling elements may be equal in size and or diameter; however, different sized rolling elements in diameter or length maybe used. Preferably. the drive means may be motor-driven and the rolling elements arranged to lay one above the other, diagonally, or side by side in use, however, the rolling elements may be arranged in any other way.
Preferably, the drive means for the rolling elements can be motor-driven, for example using AC mains electrical power source. However, the rolling elements can be driven using a self-contained power source or battery power. Additionally, the rotting elements may be driven by other forms of energy such as fuel oil or gasoline, steam, compressed air, compressed oil etc., or by using manual means, for example, by connecting one of thqyolling elements to a cranking handle, reserved kinetic energy or a spring wound mechanism, friction between two elements such as the between the surface and user (of the cleaning device) kinetic force and so on. The drive means of the rolling elements may be driven by other means such as hydraulic and pneumatic means. Freely available kinetic motion may be harnessed by connecting the one or more ofthe rolling elements via crank and or cam means of associated or nonassociated elements that produce the kinetic energy.
Alternatively, one of the rolling elements may be free-running and will be driven by frictional contact with the other rolling element which is mechanically rotated, whereby the surface of the rolling elements are furrowed or grooved to allow frictional contact with each other's ends and the absorbent resilient flexible material passing in between. The grooved rolling elements may also enhance effective compression of the absorbent resilient flexible material. It may also be possible to gutter the surface of the rolling elements, for example, by using a series of shallow auger-like grooves cut along the surface of the rolling elements to aid in guiding liquid inwards a preferred direction.
In another embodiment, the liquid urging means may be a pair of rolling elements that are hollow and possess a plurality of perforations on the cylindrical surfaces so that when a suction force is applied inside the hollow perforated rolling elemeniC the liquid being forced out of the absorbent resilient flexible material due to the compression of the perforated rolling elements against the passing absorbent resilient flexible material is sucked into the hollow section of the perforated rolling elements via the perforations on the surface of the hollow rolling elements via suction force, sending the waste liquid away from the perforated rolling elements to a waste storage container via conduits fluidly connected to the liquid catchment means enclosure module. Such a storage container maybe placed within the chassis or away from the chassis. A main advantage of this method of suctioning liquid expelled from the passing absorbent resilient flexible material is thatthe cleaning device can be used to clean vertical surfaces such as walls and upside-down surfaces such as the inside top of rooms or ceilings.
In another embodiment, the hollow rolling elements with plurality of perforations may be stationary or non-rotatable and placed slightly apart to allow space for ease of access for the absorbent resilient flexible material in-between the non-rotatable rolling elements, whereby liquid is sucked thru the perforations on the surface of the hollow siatinarv non-rotatable rolling elements in much the same method described above as with the perforated rolling elements suction means.
In certain embodiments ofthe above aspect, the liquid urging means may be a liquid or a gas medium or a mixture of both liquid and gas under pressure that is forced through a port at high velocity into an empty or void liquid catchment means enclosure module, so that the high pressure forms a plenum thereby allowing the force of the pressure to dislodge and or flush waste liquids and debris away from the passing absorbent resilient flexible material and sending such waste liquid and debris away via conduits fluidly connected to the plenum of the liquid catchment means enclosure module, to the storage container within an integrated part of the chassis, or otherwise sending the waste liquid away from the cleaning device, thereby continuously ensuring that the absorbent resilient flexible material is being regenerated continuously before emerging from the liquid catchment means enclosure module to recur making contact with a surface being cleaned. Thus, wiling elements and the non-rotatable rolling elements may be completely absent from the enclosure of the liquid urging means so that when a force of suction or blowing force is introduced into the void liquid catchment lliCaflS enclosure module, a powerful plenum is formed inside the enclosure thus forcing liquid and debris to dislodge or out of the absorbent resilient flexible material as it is continuously passing through the void liquid catchment means enclosure module. In such an embodiment, the absorbent resilient flexible material may be in the form of, or similar to brushes and or duster microfiber dust-mop type filamentary strands generally used for drier surface sweeping and light moisture removal in supermarket and mall floor surfaces; however, the mechanism can be used in a full surface wet cleaning operation by the cleaning device in such a ramification.
In a certain embodiment of the above aspect, the liquid urging means may be a cam or clamping arrangement which comprises oscillating clamping elements wherein the absorbent resilient flexible material being configured to pass in-between the oscillating clamping elements for regeneration or to remove liquid and debris from the continuously passing absorbent resilient flexible material by the compression force of the oscillating clamping elements. In such an embodiment, the intermittent eamnhing compression by the oscillating clamping elements against the absorbent resilient flexible material may be con Figured to grasp and puii' the absorbent resilient flexible material; however, the absorbent resilient flexible material may be rotated or revolved by a separate drive means. Thus, it may be possible to have the rolling elements movably attached to a resiliently fluctuating or independently moving support member movably connected with the liquid catchment means enclosure module. This springy fluctuations or independently movable structure holds the rolling elements in place during different tensions, torsions and paces encountered as the absorbent resilient flexible material passes between the rolling elements thus compensating counterbalance or cantilevering of the rolling elements working within the liquid catchment means enclosure module.
Preferably, the absorbent resilient flexible material may be belt or substantially annular, that is, the absorbent resilient flexible material may take the form and structural shape of a ring, and the ring been rotatable concentrically or eccentrically, and have any cross-sectional thickness, width or shape, such as semi-circular, circular, square, elliptical, rectangular, hexagonal, oblong, triangular etc., or be a combination of two shapes such as a circularly and squarely shape, and may have its surface furrowed or ribbed, for the purpose of absorbing liquid from any extended surface been cleaned by the self-regenerating surface cleaning device4lowever, the absorbent resilient flexible materi& may be in the form ofa disc.
In certain embodiments of the above aspect, the absorbent resilient flexible material is a flexible highly absorbent and flexible material such as PVA or polyvinyl alcohol, which can be derived sustainably and is biodegradable, has high chemical resistant against organic and non-organic solvents such as oil, grease, bleach etc., it is durable -has high abrasion resistance thus its strong and hardwearing, non-noxious when burned, has high tensile strength and flexibility, as well as high oxygen and odour barrier properties which transiates into resistance to bacteria harbouring thus reduced deterioration, discolouration, shrinking and degradation caused by fungi and bacteria that is resultant in bad odours. PVA is super absorbent and non-toxic, has fast Liquid absorption speed and high liquid absorption rate, has high liquid absorption ratio in comparison to its dry weight thereby absorbing and retaining a high amount and weight of liquids such as water in comparison to its size and weight ditTerence, one advantage of this quality is that PVA picks liquids spilt accidentally, for example on carpets or upholstery ihst and before the carpet or upholstery material begins to absorb the liquid. [WA has a melting point of 23U''C, is resistara to ultraviolet rays, therefore a preferable material for intensive sanitizing applications such as steam cleaning by use of the cleaning device described herein.
Preferably, the absorbent resilient flexible material may be eccentrically or concentrically revolving or rotatably mounted on the chassis; means for supporting the absorbent resilient flexible material towards a position in which the absorbent resilient flexible material is continuously passed via the liquid catchment means enclosure module and in between the rolling elements for regeneration, before been released from the liquid catchnient means enclosure module to recur or repeat the cycle of absorbing and collecting liquid and debris from a surface been cleaned by the cleaning device.
Preferably, the absorbent resilient flexible material extends along the width or the transverse axis of the chassis of the cleaning device making utmost footprint contact with the cleaning surface along the width of the transverse axis of the cleaning device when the cleaning device is moved across a cleaning surface in a forward or backward direction. Preferably, the absorbent resilient flexible material is positioned along the edge on aft direction of the transverse axis of the chassis.
However, in certain embodiments, the absorbent resilient flexible material may encircle or surround the entire forward, aft and transverse edges oi' the cleaning device.
in other embodiments of the above aspect, the absorbent resilient flexible material may be a non-rotatable structure such as a semi-circular ring, partial disc or an oblong block, such that, the liquid eatebment means enclosure module oscillates along the length of the partial block of the absorbent resilient flexible material in contact with the cleaning surface so as to clean a surface, and get simultaneously regenerated by the oscillating liquid catchinent means enclosure module, in such an embodiment where the liquid catchment means enclosure module oscillates on the absorbent resilient flexible material for regeneration provision, rolling elements may be positioned on the side opposite the interior of the basin of the liquid catchment means enclosure module in order to roll on the surface being cleaned using the cleaning device.
in certain embodiments, the cross-section ofthe absorbent resilient flexible material may be made up of' more than one different type or layers of material makeup or constituents, for example, a combination ofa less absorbent coarse material and or adjacent to a more absorbent smooth material.
Preferably, the layers of different materials adjacent to each other may be running longitudinally in a lateral orientation, whereas where the orientation is a disc, the layers may be running in radial, or preferably, in rings. For example, an absorbent resilient flexible material composed of two different materials such as leather and sponge, PVA and sponge, hard foam and soft sponge, polyethylene and sponge, nylon and sponge, layers of cotton, rubber and microfiber cloth may be bonded or stuck together via welding, gluing, fusing, stitching and etcetera, so that an absorbent resilient flexible material may be divided cross-sectional by two different separate types of layers of material, so that in a cross-section comprising an absorbent material such as PVA joined with a less absorbent rougher foamy sponge, the less absorbent rougher foamy sponge may act as a scrubber whilst the more absorbent sponge collects the liquid. The advantage of such a combination of two different types of material is that the surface been cleaned is scrubbed and dried at the same time using a single portion of a cleaning material.
In certain embodiments of the above aspect. tiw absorbent resilient flexible material may be a block in ally structural shape and thickness such as a semi spherical, semi-circular, elliptical, circular, cylindrical, oval, or be of any other partiat structural shape, such as that of a block that is non-circularly, for example, a square block, rectangular block, hexagonal block, triangular block, oblong block etc., and thus it may be in the structural shape oTh disc, strip, block, belt, rack, chain, wheel, plate etc. Thus, the absorbent resilient flexible material may take any shape, thickness or form, and may even have guide-notch-grooves, and, or notches on its surface. The guide-notch-grooves on the surface of the absorbent resilient flexible material may act to collaborate with guide means on the structure of the cleaning device for leading the absorbent resilient flexible material towards and into continuous contact with a surface been cleaned by the cleaning device, and then leading the absorbent resilient flexible material around the cleaning head of the cleaning device and in between the rolling elements within the liquid catchment means enclosure module continuously.
Prcferab?y, the absorbent resilient flexible material may be supported in and around the chassis and * whilst entering and exiling or leaving the Jiqu catehment means enclosure module by guide means.
The guide means may comprise rolling means fixed along the side-walls and passageway corridor where the absorbent resilient flexible material continually passes through. The rolling means may comprise at least one of, or a combination ofthe following, a groove, track, rail, rack, pinion, notched pulleys, sprocket. rollers etc.. fixed along the side-walls of the passageway of the continuously passing absorbent resilient flexible material as it continuously enters and exits the liquid catchment means enclosure module. One advantage of this mechanism is that the absorbent resilient flexible material is maintained in alignment during operation, thereby reducing drag, wear and tear thus saving electrical energy and bearing loads. Another advantage of this arrangement is that the pressure applied upon the operating absorbent resilient flexible material can be increased or decreased or even that the absorbent resilient flexible material may be entirely lifted away from contact with a surface being cleaned whilst without lifting the structural cleaning head of the cleaning device from the cleaning surface.
Preferably, receptive guidc-in elements such as ro!lcrs, and, or submissive rounded-lip edges may be situated at the mouth of the aperture and within the edges of compartments inside the enclosure of the liquid catchmcnt means enclosure module. This arrangement enhances lot added efficiency and less drag. Preferably, the compressed cross sectional length of the absorbent resilient flexible material is approximately that of the length of the rolling elements. Preferably, the cross-sectional shape of the absorbent resilient flexible material is squarely with curved or filleted edges to maximise spread along the entire lengths of the rolling elements, and to attain a wider footprint on a cleaning surface.
However the cross sectional shape ofthe absorbent resilient flexible material may consist of any other shape such as round, oval, square, oblong, hexagonal. elliptical, circular, or semi-circuiar, triangular, or an amalgamation of two such shapes such as triangularly and squarely shape, circular and squarely shape etc. The surface of the absorbent resilient flexible material may be furrowed or grooved to increase liquid collection and disposal capabilities, surface rubbing and crevice reaching capacities.
The furrowing may also help to reduce slippage when encountering the rolling elements within the liquid catchment means enclosure module.
Preferably, the absorbent resilient flexible material may be attached to one or more support structure; wherein the support structure may he rigid orifexible. In such a constitution the support structure may be in the structural shape of a ring, or annular. the cross sectional thickness, width, shape, composition or texture may vary from that of the absorbent resilient flexible material. The cross sectional shape of the support structure may be semi-circular, circular, square, elliptical, rectangular, hexagonal, triangular etc., or be a combination of two shapes such as a circularly and squarely shape, However, in another embodiment the support structure may be of any other shape such as semi-circular, circular, square, elliptical, rectangular, triangular, plate etc., and thus it may be in the structural shape of a disc, strip, block, ring, plate, belt, rack, cylinder etc. Guide grooves with configurations such as, rack, pinion, track, rail, notches, grooves teeth etc., may be formed on the edges of the support structure in this aspect to aid in drive means and guide means. Guide means may be rolling means such as pulleys, sprockets, wheels, etc., rotatably fixed on the chassis in order to continuously and smoothly enable ease for the absorbent resilient flexible material going via the rolling elements within the liquid catchmcnt means enclosure module for regeneration before continuously obtaining contact with a suriacebeen cleaned by the cleaning device. One advantage of this mechanism is that the absorbent resilient flexible material is maintained in alignment during operation, thereby reducing wear and tear thus saving energy due to less drag. Another advantage of this arrangement is that the pressure applied upon the operating absorbent resilient flexible material can be increased or decreased or even that the absorbent resilient flexible material may be entirely lifted away from contact with a surface being cleaned whilst without lifting the structural head of the cleaning device from that surface been cleaned.
In yet other embodiments, the support structure having fixed onto it the absorbent resilient flexible material which is on contact with the cleaning surface may not be a flexible material but a rigid material, such a support structure may be in the shape of a disc and or a ring with teeth on the edge of the disc arid or ring to enable toothed drive wheels to drive the support structure. In such embodiment, driving means for such a disc and or ring may be done via a circumferentially disposed rack and pinion configuration whereby corresponding teeth may be ul around the circumferential edge of the disc and or ring so that a drive wheel with øorresponding wheels can be engaged for driving the support siructure in the shape of a disc and or ring. The same rack and pinion configuration may be used to drive a non-circular structure, such as a strip or block from side to side.
Preferably, the support structure of the absorbent resilient flexible material may be made from a soft pliable flexible and durabre material that can be repeatedly bent compressed and stretch without fracturing, such as plastic resins, rubber resins, rubber, cotton, silicone, nylon, polyurethane foam, polyethyleneterephthalate or PET, vinyl, polypropylene, pcilystyrene, leat her, sisal, silk, neoprene, various impregnated or laminated fibrous materials, various plasticized materials, cardboard, paper etc. The. absorbent resilient flexible material may be attached to the support structure by means such as gluing, sewing, stapling, laminating, welding, cementing, vulcanising, Velcro, fusion, etc. A certain method of attaching the absorbent resilient flexible material together with the support structure is by pouring a liquid rubber resin into a mould for forming the support structure, and with the absorbent resilient flexible material positioned substantially in place within the mould, and leaving exposed the portion or face of the absorbent resilient flexible material that comes into contact with a surface been cleaned; having well-spaced liQuid rubUer resin passages in the other or opposite portion ot' the absorbent resilient flexible merial that is to be then submerged into the resin for support permanently bonding and forming the support structure once the liquid rubber resin hardens, thereby funning the support structure that is contiguously interlocked with the absorbent resilient flexible material, after been released from the mould. An advantage of this method of attaching the absorbent rcsilicnt flexible material to the support structure is that the integrated body is more compact as joining gaps are eliminated, thus inhibiting wear and tear to the absorbent resilient fle.xibie material as it continuously passes via the compression of the rolling elements. Bonding PVA and a resin in this way may be done by submerging the tWA in the resin while the PVA is in a dry and compressed state.
a certain embodiment of the above aspect whereby the, support structure is a flexible ring such as a belt or band, more than one material for cleaning a surface may be attached to both end-rims of the belt, so that a coarser material may be aflached on one end-rim, and a smoother more absorbent material may he attached on the opposite end-rim of tI: belt loop. This configuration may be applicable where the head oithc cleaning dcvjce is configured to use on one or more single belt loop with separate alternating scrubbing and drying materials attached to both end-rims of the belt loop; and the belt configured to be twisted or warped by guide means around an axis of 180' inversion, during the moments when the travelling belt goes thai the continuous journey via the passageways and liquid catchment means enclosure module and the cleaning surface. The of] 800 inversion allows the for the alternation of the scrubbing and absorbing action to be carried out in a cleaning head of the cleaning device using a single belt ioop with separate different cleaning attachments on either end-rims of the belt, and the belt loop exposed at separate apertures on the cleaning head proximate and facing the cleaning surface along the cleaning width so that only one of the exposed end-rims of the belt with cleaning material attachment interacts with the cleaning surface. It may be possible to have a pivotal frame holding the guide means where the belt runs along so that a reciprocation of the scrubbing action and the drying action may be attained separately. However, the cleaning head may work adequately without the need ofa pivotal frame, In another embodiment, the support structure may be made from an inflexible or rigid material that can he repeatedly used without fracture, such as hardened plastics and reinforced fibres, alloys and metals such as aluminium, chains, wood. glas ceramics etc. The absorbent resilient flexible material may be attached to the suppor structure by means such as gluing, stapling, laminating, welding, nailing, vuleanising, Velcro, fusion, smelting, chemical bonding etc. In certain embodiments, where the support structure is not a flexible material but a rigid material, such a support structure may be in the shape of a disc and or a ring with teeth on the edge of the disc and or ring to enable toothed drive wheels to drive the support structure. In such embodiment, driving means for such a disc and or ring may be done via a circumferentially disposed rack and pinion configuration whereby corresponding teeth may be cut around the circumferential edge of the disc and or ring so that a drive wheel with corresponding wheels can be engaged for driving the support structure in the shape of a disc and or ring. The same rack and pinion configuration may be used to drive a non-circular structure, such as a strip or block from side to side.
In a certain embodiment the support structure is not a flexible material but a rigid material in the shape of a disc or plate and the absorbent resilj.nt flexible material attached to at least one side or face of the disc or plate, and the support structure rotatably attached to the chassis and driven from the diametrical centre of the disc so that the absorbent resilient flexible material is sufficiently regenerated by the rolling elements as it continuously enters and exits the liquid catchment means enclosure module. Further to the above aspect where the support structure is not a flexible material but a rigid material in the shape of a disc or plate and the cleaning material attached to both surfaces, face or sides of a single disc or plate, so that a coarser material may be attached on one side of the disc, and a smoother more absorbent material may be attached on the opposite side of the disc and rotatable from the diametrical centre of the disc. This configuration may be applicable where the head of the cleaning device is configured to use on one or more single disc with separate alternating scrubbing and drying materials attached to both sides of the disc's face; and the disc configured to be flipped or rotated around an axis of 180° inversion so that when a user needs to scrub a surface, the disc is flipped to so that the side of the disc with the coarser material attached can be exposed and used to clean the surface by scrubbing, and the same fbr using the opposite softer more absorbent side of the disc to dry a surQice, Flipping the disc. iay be done by lifting the cleaning device offa surface or tilting the device on its side while the flipping is perlbrmed. The 1800 inversion is attainable since the disc is partially held in place so as to interact with the workings of the liquid catchment means enclosure module that niay have support members extended to the diametrical centre of the disc, and the liquid catchment means enclosure module rotatably mounted on the chassis for periodic flipping of the disc, and the area of the disc that attains contact with the cleaning surface provides a cleaning width across a cleaning surface that is the length of the disc's diameter.

Rinsing or regenerating the absorbent material in this embodiment can be done in a number of ways such as by applying a rinsing fluid along the rotating absorbent material at a certain convenient (away and before the suctioning position has been reached by the rotating absorbent material) circumferential angle of the rotating absorbent material by use of liquid applicators positioned within the circumferential chamber of the rotating absorbent material before re-emerging to recur contact with the cleaning surface cleaning surface at an aperture facing the cleaning surface. Another means to regenerate the rotating absorbent material may be done by using the liquid applicators of the cleaning device to apply a clean Iluid onto the cleaning surface prior to the rotating absorbent material collecting the cleaning fluid from the cleaning surface is equivalent to rinsing or regenerating the rotating absorbent material for continuous surface cleaning. Other means to regenerate a cleaning element using a clean fluid as a rinsing element for the purpose of constantly regenerating or removing contaminant substance collected from a cleaning surface7by the cleaning element operating within a cleaning device as disclosed in this patent is equivalent to regenerating the cleaning element for continuous cleaning upon a cleaning surface by a cleaning device and in particular to the regeneration of the.
cleaning element which makes final or last contact with a cleaning surface across a cleaning width.
In yet another certain embodiment of the above aspect, where the support structure is not a flexible material but a rigid material such as in the shape of a rod, and the rod acting as a spindle whereby a plurality of absorbent and or non-absorbent material strands or strips are attached on evenly along its surface length, and the spindle configured to rotate around its axis at a substantial speed while maintaining contact with a cleaning surface along a cleaning width, thereby being able to collect liquid and debris from a cleaning surface via the absorbent material attachment to the spinning spindle, as whilst the rod rotates, the absorbent material flicks and collects liquid and debris which is then forced into a centrifugal separation chamber or receptacle by the centrifugal force produced by the spinning absorbent material attached to the spindle, the receptacle being part of the body of the liquid catchment means enclosure module that has an aperture on the cleaning head exposing the spinning absorbent material upon and faciig the cleaning surface. Rinsing or regenerating the absorbent material in this embodiment can be done in a number ofways such as by applying a rinsing fluid along the body of the spinning absorbent material at a certain convenient predefined angular position using liquid applicators fixed within the circumferential chamber of the spinning absorbent material before it re-emerges to recur contact with the cleaning surface at an aperture facing the cleaning surface. Another means to regenerate the spinning absorbent material may be done by applying a clean fluid onto the cleaning surface prior to the spinning absorbent material picking the cleaning fluid from the cleaning surface is tantamount to rinsing or regenerating the spinning absorbent material for continuous surface cleaning by the cleaning device. Other means to regenerate a cleaning element using a clean fluid as a rinsing element for the purpose of constantly regenerating or removing contaminant substance collected from a cleaning surface by the cleaning element operating within cleaning device as disclosed in this patent is equivalent to regenerating the cleaning element for continuous cleaning upon a cleaning surface by a cleaning device and in particular to the regeneration of the cleaning element which makes final or last contact with a cleaning surface across a cleaning width Thus, it shall bc notcd that cleaning components of a certain cleaning apparatus arranged to apply clean fluid via liquid applicator onto the cleaning surface prior to passing a cleaning material over said cleaning surface shall constitute to an indirect act of rinsing the cleaning material during a cleaning cycle, so that continuous cleaning and drying of the cleaning surface using the cleaning material is accomplished by a certain cleaning apparatus. Similarly, cleaning components of a certain cleaning apparatus arranged to apply a clean fluid via liquid applicator onto a cleaning material prior to said cleaning material encountering a liquid removal means shall constitute to directly rinsing the cleaning material during a cleaning cycle of that cleaning apparatus cleaning that surface is an infringement of the cicaning device disclosed herein this patent disclosure.
In the preferred embodiment, the pull-push action of the roiling elements forces the absorbent resilient flexible material attached to the support structure to be in a continuous cycle and maintaining contact with a surface being cleaned, before sending the absorbent resilient flexible material via the rolling elements within the liquid catchment means enclosure module. Thus, the support structure attached to the absorbent resilient flexible. maf'erial may be rotatably connected to a drive means. The drive means cnsurcs that the support structure with which the attached absorbent resilient flexible material is driven. This would normally be occurring at the same time as the absorbent resilient flexible material attached to the support structure passes between the rolling elements within the liquid catchment means enclosure module. The drive means may be elements connected to a combination of components such as, gear arrangements means, sprockets, rack and pinion, pulleys, planetary gears, chains, belts, rails, tracks, pulley notches, etc. Thus, the absorbent resilient flexible material attached to the support structure may be motor-driven using self-contained power source or from a mains electrical AC power source. The drive means of the support structure, absorbent resilient flexible material, rolling elements may also be motor-driven by other means such as fuel oil or gasoline, gasohol, steam etc., for rotating, revolving and continuously forcing the absorbent resilient flexible material attached on the support structure to be lead into the liquid catchment means enclosure module for regeneration before recurring to obtain contact with a surface been cleaned during a certain cleaning cycle ofthe cleaning device. The drive means ofthe rolling elements may be also driven by other means such as hydraulic and pneumatic means.
In a certain embodiment, it may be possible to run the cleaning device using no electrical power by using motive energy wherein motive energy is derived from sources such as the users kinetic energy derived from the friction force between rolling elements fixed on the undercarriage of the cleaning device and the cleaning surface thereby converting the users motive energy and transforming it into mechanical energy that runs the workings of the cleaning device thereby saving electrical energy.
In another embodiment of the above aspect, since it is possible to symmetrically mirror the arrangements of the enclosure of the liquid catchment means enclosure module and compartments with their independent workings thereof, along the passing absorbent resilient flexible material, it may therefore be possible to modify the configurations of the receptive rollers at the mouth of the aperture to correspond or align with the cross-sectional profile of the support structure holding the continuously passing absorbent resilient flexible material on either side of the support structure cross-sectional profile.
Preferably, thc support strucLure may he pivotally attachcd to the chassis of the clcaning dcvice.
In yet another embodiment of the above aspect, the absorbent resilient flexible material may be configured to become regenerated in much the same way as described above, but with the roles of the same components reversed. That is, the liquid catchment means enclosure module is a moveable carriage that is configured to follow or trail a permanently fixed or stationary absorbent resilient flexible material, for regeneration. Therefore instead of the passing absorbent resilient flexible material been led into a stationary liquid catchment means enclosure module as it is described in the preferred embodiment of this patent disclosure, the liquid catehment means enclosure module is movable and follows the absorbent resilient flexible material for regeneration during a cleaning operation on cleaning surface by the cleaning device. Thus, in this embodiment, a rolling component may be rotatable fixed underneath the trailing liquid catchment means enclosure module carriage so that scraping and dragging the cleaning surface is avoided during a cleaning cycle as the liquid eatchmcnt means enclosute module carriage continuously rotates, revolves or oscillates a stationary absorbent resilient flexible material for regenation during a cleaning cycle on a cleaning surface by the cleaning dcvi cc.
The course or path at which the trailing liquid catchment means enclosure module carriage follows the stationary absorbent resilient flexible material may be determined by various factors such as the shape of the cleaning head frame of the cleaning device, which may determine the trailing path at which the transportable liquid catchment means enclosure module may trail or follow at such as squarely with filleted edges, triangular, circular, oval, elliptical, or a blend of two shapes e.g. an oval and an oblong shape in a cleaning head configuration, etc. Thus, the liquid catchment means enclosure module carriage may be transported around the permanently fixed absorbent resilient flexible material by been connected to transport means such as. on a track, rail, chain, rack and pinion arrangement, a centrally or diametrically position rotatable boom arm connection that rotates around the centre of a circularly and permanently fixed absorbent resilient flexible material. It may be possible to have the liquid catchment means enclosure module carriage on a non-circularly arrangement such as when the movable liquid catchment ireans enclosure module carriage moves to and I'm along a crossways or sideways nloti9n to regenerate a permanently fixed block absorbent resilient flexible material operating on a cleaning head during a cleaning cycle on cleaning surface.
Further, the structural cross-section shape of the permanently fixed absorbent resilient flexible material that is fixed on rigid support structure by gluing or clamping etc., so that the movable liquid catchment means enclosure module carriage moves to and fro or revolves or rotates around a guide rail may be triangular, circular, cylindrical, oval, elliptical, ring, rectangular, strands or filaments of material, hexagonal etc., and may be a blend of one or more cleaning materials such as a coarser less absorbent material, and a smoother more absorbent material.

The absorbent resilient flexible material can also be configured to be a semi-circular or partial block configured to be regenerated by a movable liquid catchment means enclosure module carriage that constantly moves back and forth in order for regeneration of the absorbent resilient flexible material to continuously take place and whilst still maintaining contact with a cleaning surface during a cleaning cycle of the cleaning device.

ihe scrubbing element contacts the cleani surface during cleaning operations and agithies the cleaning fluid provided by one or more surface-liquid applicator to mix fluids with contaminants and emulsify, dissolve or otherwise chemically react with the contaminants. The scrubbing element also generates a shearing force as it moves with respect to the cleaning surface and the force helps to break adhesion and other bonds between contaminants and the cleaning surface. In addition, the scrubbing element may be passive element or an active and may be configured to be movable into and out of contact with the cleaning surface. In one embodiment of the present invention, a passive scrubbing element is attached to the base of the chassis of the cleaning device and disposed to contact the cleaning surface across the cleaning width. A force is produced between the passive scrubbing element and the cleaning surface as the chassis is transported in a forward, backward or sideways direction. An ultra-sonic sound emitter may also be used to produce scrubbing action. The passive scrubbing element and or active scrubbing element may comprise a plurality of scrubbing bristles held in contact with the cleaning surface, a woven or a non-woven material e.g., a scrubbing pad or sheet material held in contact with the cleaning surface, or a compliant solid element such as a sponge or other compliant porous solid foam element held in contact with the cleaning surface. The scrubbing element may be configured to be replaceable by a user. Preferably, a cleaning fluid applicator configured to apply a cleaning fluid onto the cleaning surface and scrubbing element simultaneously or configured to apply a cleaning fluid onto the scrubbing element which in turn smears the cleaning fluid onto (lie cleaning surface; arid the cleaning fluid app! icator is arranged along the entire width of transverse axis of the cicassis and may be placed at a central position to the scrubbing element, or at the front and rear, or at the left and right or around the scrubbing element.
Preferably, the scrubbing element is made from a permeable spongy material, alternatively scrubbing element made from brushes, wool, mitts, steel wool, nylon, abrasive material, microfiber cloth, cotton, scouring pad etc. In certain embodiments where the regenerating absorbent resilient flexible material surrounds the entire periphery base of the chassis thus making the absorbent resilient flexible material the final cleaning element to make contact over the cleaning surface when transporting the chassis in a forward, backward or sideways direction thereby avoiding leaving any markings on the cleaning surface, such as leaving wheel markings where the chassis is equipped with wheels. In such and other certain embodiments of the above aspect, more than one regenerating absorbent resilient flexible material may be configured to operate under a single base of the chassis of the cleaning device, and may be Further configured to revolve and or rotate in unison or opposite directions, and even have separate tasks such as; the following absorbeju resilient flexible material in a chassis arrangement moving forward over a cleaning surface being configurcd to wipe and dry the cleaning surface after the preceding scrubbing absorbent resilient flexible material. Thus the base of the cleaning device may have different sized regenerating absorbent resilient flexible material and may be made from different materials to perform different tasks such as scouring and drying a cleaning surface; and the regenerating absorbent resilient flexible materials may be placed side by side, overlapping one another, one larger than the other etc., working in a single base of a cleaning device. In certain embodiments the base of the chassis of the cleaning device may be further added a surface sanitizing element or an ultra violet ray emitter to destroy harmful microbial elements and substances when moving the chassis of the cleaning device over a cleaning surface, wherein such an embodiment, the ultra violet ray emitter may be fixed with the ray emissions beaming onto the cleaning surface to destroy harmful microbial elements and substances on a cleaning surface.
The chassis of the cleaning device may also include separate tanks or liquid containers for storing -p spent clean fluid, containers for storing fresh cleaning fluid, and also soap or detergent container.
The chassis of the cleaning device is provited with electrical power delivered from an electrical mains AC power source outlet and may carry a self-contained power source or rechargeable power subsystem for providing the energy to power the entire surface cleaning device during the time when the cleaning device is not connected to the AC power source.
Preferably, the surface-liquid applicator(s) are attached to the chassis of the cleaning device and configured to apply a rinsing fluid onto the surface being cleaned; and the surface-liquid applicator positioned in the transverse axis perpendicular to the for-aft axis of the chassis so that the rinsing fluid is applied onto the cleaning surface across the cleaning width of the chassis.
Preferably, the chassis of the cleaning device may carry a first cleaning region and a second cleaning region. The first cleaning region may comprise cleaning components arranged to collect loose particulates from a cleaning surface across a cleaning width. Preferably, the first cleaning region also includes cleaning components configured to scrub the cleaning surface. The cleaning components of the first cleaning region utilize a vacuuming means via a vacuuming port disposed on the transvcrse edge of the cleaning device and configured toluction up loose particles from a cleaning surface; and wherein the arrangement of the vacuuming port with respect to the scrubbing element causes the vacuuming port to precede the scrubbing element over a cLeaning surface when transporting the chassis in a forward direction. Alternatively, the cleaning components ofthe first cleaning region may utilize brushes to sweep the loose partieulates into a receptacle or otherwise remove the loose particulates from a cleaning surface. The first cleaning region may also carry further cleaning components arranged to apply a cleaning fluid onto a surface. Thus, surface-liquid applicator may be provided on the first cleaning region to provide soapy solution as desired by the user operating the cleaning device; and wherein the arrangement of the surface-liquid applicator in the first cleaning region with respect to the scrubbing element causes the scrubbing element to follow the surface-liquid applicator when transporting the chassis over the cleaning surface in a forward direction.
The second cleaning region may comprise cleaning components arranged to collect spent liquid from a cleaning surface across a cleaning width of' the cleaning device. The cleaning components of the second cleaning region utilize the absorbent resilient flexible material disposed on the transverse and perpendicular cleaning width edge of the clening device and configurcd to collect liquid from the cleaning surface, leaving the surface in a dry and clean state.
The second cleaning region may also carry further cleaning components arranged to apply a cleaning fluid onto a surface. Thus, surface-liquid applicator may be provided on the second cleaning region to provide rinsing fluid; and wherein the arrangement of the surface-liquid applicator with respect to the absorbent resilient flexible material causes the absorbent resilient flexible material to follow the surface-liquid applicator when transporting the chassis over the cleaning surface in a forward direction.
Thus, the arrangement of the absorbent resilient flexible material with respect to the scrubbing element in the first cleaning region may also cause the absorbent resilient flexible material in the second cleaning region to follow the scrubbing element in the first cleaning region, and the surface-liquid applicator in the second cleaning region when transporting the chassis of the cleaning device in a forward direction across the cleaning surface. The arrangement of the scrubbing element in the first cleaning region causes the surface-liquid applicator in the second cleaning region to follow the scrubbing element over a cleaning surface when transporting the chassis in a forward direction.
The arrangement of the scrubbing element causes the surface-liquid applicator in the second cleaning region to precede the absorbent resilient flexible material when transporting the chassis in a forward direction across a cleaning surface.
In certain embodiments, the vacuuming means may be further extended to become introduced and or disposed adjacent the first cleaning region and the second cleaning region or in-between the scrUbbing element and the surFace-liquid applicator, in the second cleaning region so as to collect the waste liquids and the dirt pror to the surfaEc being rinsed by the surface-liquid applicator in the second cleaning region and absorbent resilient flexible material.
Preferably, the first cleaning region may be positioned centrally and symmetrically mirrored outwards from the midpoint of the transverse axis and along the base of' the cleaning device.
Similarly, passing absorbent resilient flexible material being supported on a pivotal support means (not shown) which may extend the absorbent resilient flexible material to contact the cleaning surface or retract absorbent resilient flexible material from contact with surface object. These oscillating mechanical means allow for separate vacuuming and wet cleaning applications to be performed on the cleaning surface by the cleaning device. In other embodiments, the oscillating mechanical means allow alternating vacuuming and wet cleaning operations during forward and backward passes of the cleaning device upon the cleaning surface so that sufficient cleaning surface cleaning efficiency is achieved at whichever direction the cleaning device is transported across a cleaning surface during a cleaning cycle of the cleaning device. In a certain embodiment, the first cleaning region and the second cleaning region may be positioned centrally and symmetrically mirrored outwards along the * transverse axis of the base of the chassis of the cleaning device so as to be surrounded, encircled or encompassed by the absorbent resilient flexibte material.
Preferably, the power source delivers electrical power to all of the major cleaning device subsystems.
Preferably, the power source of the cleaning device is delivered from an electrical mains AC power source or outlet and is managed by a central or main control unit. The power source includes an electrical power interface unit for delivering power to the cleaning device. However, the cleaning device may include self-contained power source configured into the body of the cleaning device, e.g., a rechargeable battery. Additionally, the self-contained power source is configured to be recharged by any one of the recharging elements or modes, or the battery may become replaced by a user when it becomes discharged or unusable. In some embodiments, the rechargeable battery may be fixed within the chassis of the cleaning device so that the cleaning device can derive electrical power from the rechargeable battery during the time when the cleaning device is not connected to the power source.
The main control unit may interface with the power source to control the distribution of power, to monitor power use and to initiate power conservation modes as required within the cleaning device.
The entire self-regenerating surthce cleaningilevice with microbial screening device is powered by either DC or direct current or AC or alternating current electricity and is controlled by the main control unit or on-board computer system. Preferably, the cleaning device can be configurable to be powered by either of both AC and or DC power supply; wherein utilizing AC power supply connects the cleaning device to a mains electrical cable for power. The power source ofthe cleaning device can be configured either to be powered by AC electrical current or DC electrical current respectively.
Electrical power is distributed around the cleaning device to perform various tasks and within the overall control of the main control unit once a user activates a command. In certain embodiments, the cleaning device may have AC electrical interface port for temporary mains electrical cable connection to recharge a self-contained power source. In other embodiments, electrical current transient trip switches which transfer electric current between AC and DC outputs may be employed; wherein electrical currents scavenged from one or more free-running elements in motion within the workings of the cleaning device may be tapped, and the current stored into the rechargeable battery units within the cleaning device. Such currents may be tapped using micro or mini-dynamos attached to convenient spaces', say, along rotating drice shaft extension or other preferred location as long as it does not hinder or add further burdening of the overall efficiency of a particular component or secondary part or device (such as a motor) of the cleaning device in general. The self-contained power source may be rechargeable battery attached to the cleaning device. However, the cleaning device may be powered by AC electricity from the mains supply via cable connection to power the cleaning device during use. Thus, the power source of the cleaning device may further provide or deliver power to all the subsystems and or mechanical workings and electrical components within the cleaning device. The power source delivers electrical power to the cleaning device subsystems via network of interconnected wires and or conductive elements controlled by the main control unit, once a user sets a cleaning task via choosing a cleaning programme for the cleaning device to carry out.
The interconnection of the cleaning device subsystem is provided via interconnected wires and or conductive elements, for example, via conductive paths formed on storeys' or separate layers of an integrated printed circuit board, fibre-optics and or similar, as it is well known. The main control unit includes programmable or pre-programmed digital data processor, e.g., a microprocessor, for performing program steps, algorithms and oriathematical and logical operations as maybe required.
The main control unit may also include digital data memory in communication with the data processor for storing program steps and other digital data therein. The main control unit may also include timing device for sequencing processes as required by user command.
Preferably, the chassis of the cleaning device may also include one or more user input element or user input control unit. The user input control unit produces an electrical signal in response to a user input and communicate the signal to the main control unit. In one embodiment of the present invention, the main control unit, described above, provides a user input control unit however, a user may enter commands thru a programmable computer, or other programmable device such as a remote control and via voice commands. A user may input commands to initiate actions such as power ON/OFF, start, stop or to change a cleaning mode set a cleaning duration, actuate a washing and drying mode to run in combination or respectively, and or actuate prewash' or spot-cleaning' programs, cleaning surface types, interruption for choice of cleaning different stains, liquids and surface textures, user-programme input that can be manually or automaticay inputted and or actuated, among many other user initiated commands; wherein commands may be sent to the main control unit via switches that activate an electrical connection when pressed, or via any other convenient means. The main control unit includes one or more programmable or pre-programmed digital data processor, e.g., a microprocessor, for performing program steps, algorithms and or mathematical and logical operations as may be required. The main control unit may also include digital data memory in communication with the data processor for storing program steps and other digital data therein. The main control unit may also include at least one chronometer for sequencing steps as may be required.
The user input control unit may be disposed on the external surface of at least one covering element.
The covering element may be moulded to combine the form of the covering element and at least one handle component and may include one or more user manipulated actuators disposed on the user input control unit. Buttons, dials and visual lights on the user input control unit are placed conveniently and ergonomically blended on the handle component and covering element of the cleaning device.
Preferably, the seliregcncrating surface cleaning device includes at least one scraping means that may be located within the compartments of the liquid catchment means enclosure module or away from the liquid catchment means enclosure module. In a preferred embodiment, the scraping means is located substantially adjacent the mouth of the liquid catchment means enclosure module and is in contacting interaction with the passing absorbent resilient flexible material. Preferably, the arrangement of the scraping means with respect to the passing absorbent resilient flexible material travelling towards the rolling elements causes the location of the scraping means to precede that of the nozzles of the liquid applicator. However, it is not strictly essential as it may be possible to have the location of the nozzles to precede the scraping means.
Preferably, the scraping means may take the form of a brush. The brush may be in the form of a rotatable brush with bristles arranged to extend radially or outwardly in order to gain continuous contact with the passing absorbent resilient flexible material. Preferably, the bristles are made of nylon and have a diameter of about 0.02-0.05mm [O.002-0.OOsinches] and may have uniform interferences with the passing absorbent resilient flexible material which may depend on various lactors such as the intensity of debris on its surface or the pace. The bristles may be installed in the brush compartment on a bristle holder. The bristle holder may be a rod that acts as the spindle with brushes fixed and extending radially in evenly spaced slots at an even distance to ensure (hat the entire length of the absorbent resilient flexible material is sufficiently and uniformly contacted by the bristling action. Preferably the brushes are long enough to interfere with the passing absorbent resilient flexible material during rotation such that the bristles are bent by the contact with the passing absorbent resilient flexible material. Preferably the brush rotates at a direction opposite that of the passing absorbent resilient flexible material, and to attain this movement, it may be possible to use frictional contact rotatable means of transmission or gear coupling arrangement means. The gear coupling arrangement means may be a chain, belt or gearwheels. The gear coupling arrangement means may be derived from any free-running convenient rotatable component nearby the rolling elements, ft may therefore be possible to draw free-running motion by reversing the motion of the absorbent resilient flexible material frictionally e.g., by use ofa rotatable gear coupling arrangement means which frictionally makes contact with the passing absorbent resilient flexible material. An advant3ge of using the free running mcchanisth of the above gear coupling arrangement means for the brush rotation is that no considerable extra energy load is exerted on the motors since the arrangement makes use of a freely available motive energy from the velocity of the passing absorbent resilient flexible material, and even though the pace of the brush might fluctuate depending on the (variable speed at which the passing absorbent resilient flexible material travels at, the brush will always be in rotation via contact with the passing absorbent resilient flexible material and at a considerably higher ratio of speed in relation to that of the passing absorbent resilient flexible material. Also, another advantage of this arrangement is that at whichever direction the absorbent resilient flexible material revolves or moves at, say from clockwise to anticlockwise or from left to right, the brush changes or adjusts its rotational direction subsequently toward the opposing direction. An advantage of rotating the brush at a direction opposite to that of the passing absorbent resilient flexible material is that dirt and debris are flicked or rubbed off with extra force from the absorbent resilient flexible material prior to meeting with the rolling elements. Nevertheless, an electric motor may be used to rotate the brush at both directions and obtaining the equivalent results, Preferably, the bristles ai'e well spaced out radially along the central length of the spindle so that they can uniformly cover the surface of the absorbent resilient flexible material along the required full length. The spindled ends of the brush maybe secured in place for free running rotation around their axis in countersunk recessed slots or spigots bored into the chassis. Friction inhibiting means such as lubrication, bearings and washers may be placed into the recessed slots or spigots to aid in a more efficient rotation of the brush. Preferably an independent compartment whereby the scraping means is provided to rub or flick off debris from the passing absorbent resilient flexible material may be ideal in some embodiments.
In another embodiment, the scraping means may be non-rotatable, and may be provided within an individual compartment whereby the scraping means is stationary but having mutual contact with the passing absorbent resilient flexible material for the purpose of removing debris from the passing absorbent resilient flexible material in use.
In certain another embodiments, the scraping means may be in the form of a blowing or suctioning force applied into a compartment for the pucpose of removing debris from the passing absorbent resilient flexible material in use.
Preferably, the nozzles of the liquid applicator are arranged to proximately surround the passing absorbent resilient flexible material, and configured to sprinkle or expel a fluid onto the surface or face of the passing absorbent resilient flexible material. Preferably, the sprinkled or expelled fluid is a clean fluid such as water. However, the clean fluid may be any other substance depending on the nature of the cleaning cycle and premises being cleaned. The choice between sprinkling or expelling the clean fluid from the nozzles may be determined by various factors such as; by a preprogrammed sequence of the cleaning operational settings of the cleaning device; by choice of a user, when for example, cleaning a muddy surface; or by sensing means configured to sense conditions such as; to detect or measure the concentration of particulates suspended within the waste liquid solution being expelled by the exerting force of the rolling elements pressing against the passing absorbent resilient flexible material, thereby prompting the increase or decrease of the clean fluid to interact with the passing absorbent resilient flexibk materia 1hc nozzles may also be configured to be fluidly connected with the interior oldie liquid catchmcnl means enclosure module via holes hut with their liquid delivery conduits fixed on the exterior surface of the side-walls of the basin of the liquid catchment means enclosure module. An advantage of this is that more space and less friction from protuberances inside the liquid catchment means enclosure module and passageway of the absorbent resilient flexible material is obtained thereby reducing frictional drag, thereby saving electrical energy and bearing loads. Another advantage of placing the conduit feeding nozzles on the outside wall surface of the liquid eatchments means enclosure is to reduce tooling and moulding costs.
However, the conduit feeding nozzles may be flexible pipes fixed on the inside or outside side-walls of the liquid catchments means enclosure. The nozzles may also be located or configured to operate within a separate or individual compartment, and may be further configured to perform more than one task within such a compartment for interaction with the passing absorbent resilient flexible material, tasks such as, flooding a compartment with a liquid, blowing a gaseous substance into a compartment, applying a suetioning force into a compartment via conduits that are fluidly connected to the source of' the storage volumes holdin(such c1eaning substances, or suctioning and blowing devices; such storage volume containers may be within the chassis of the cleaning device or away from the entire cleaning device and such cleaning substances deliverable via conduits to the cleaning device. Thus, it may be possible to have a suctioning or fanning means fluidly connected via such conduits between the liquid catchments nieans enclosure and a fanning or suctioning means for generating a negative or positive air pressure within an individual compartment or even to the entire liquid catchments means enclosure depending on the type of cleaning process. Cleaning agents that may be used to interact with the passing absorbent resilient flexible material may vary from different
-F -p
tasks and types of contaminants targeted depending on the nature of the premises being cleaned.
Thus, some cleaning agents that may be deliverable to the compartments may be of a liquid or semi-liquid form. Such cleaning agents may include among others, vinegar, iodine, chlorine, water, steam, disinfectant, disinfection using an alcohol-based solutions such as non-flammable alcohol vapour in carbon dioxide or NAV-C02, hydrogen peroxide, silver nitrate, antiseptics, silver nitrate, bleaching agents and perfume or fragrance such as mint.
Thus, it maybe understood thatthe absorbentsilient flexible material may become partially or fully submersible into a liquid. The absorbent resilient flexible material may also become partially or fully submersible into or gaseous medium being ejected or expelled from the nozzles arranged conveniently around the passageway of the absorbent resilient flexible material before encountering the rolling elements. The rolling elements may be situated in a separate compartment from that of the nozzles. Such nozzles may also be situated in a separate compartment for interaction with the passing absorbent resilient flexible material, (he nozzles operate satisfactorily while submerged in a liquid or while not submerged in liquid.
Preferably, the clean fluid sprinkled or expelled from the nozzles is delivered from a direction away from the cleaning device via conduits. Alternatively, the clean fluid sprinkled or expelled from the nozzles may be delivered from the clean fluid storage container that is fixed within the cleaning device and can be refilled periodically.
In a certain embodiment ol' the above aspect, the mechanisms of the liquid catchment means enclosure module is replaced by a void or hollow enclosure whereby the absorbent resilient flexible material still passes through. In such an embodiment. compartmentalised partitions may not he necessary as the passing absorbent resilient flexible material may be regenerated by other methods such as by adding bursts or expulsion of a rinsing fluid rushing into the plenum void via an entry port and leaving the plenum void via an exit port within the plenum void enclosure in order to sweep away any waste liquid and debris from the passing absorbent resilient flexible material, thus leaving it sanitized and free from waste liquid and debris, before the absorbent resilient flexible material recurs to collect waste liquid and debris from a cleaning surface. Such expulsion of cleaning fluid or gas, or the mixture of both may be fluidly connected to waste volume collection chambers within the chassis of the cleaning device or connected via conduits in a direction away from the cleaning device; and a suctioning and or fanning means that may be situated within the cleaning device or away from the cleaning device and fluidiy connected to the plenum of the cleaning device via conduits.
In order to maintain the absorbent resilient flexible material in a clean regenerated state for the purpose of continuously cleaning a ditty sur-tce, the progressive cyclical principal successive steps of either; cleaning a dirty surface using the absorbent resilient flexible material, then followed by rinsing the absorbent resilient flexible material, then followed by removing the rinseate or rinse-off liquid from the absorbent resilient flexible material which is usually the final step of the regenerating cycle, so that it is now possible to successfully clean the surface once again using the now regenerated absorbent resilient flexible material has to be maintained continuously within the liquid catchment means enclosure module of this patent disclosure is paramount to the workings of the self-regenerating surface cleaning device. However, it may now be apparent that there may be a number of other ways in which the absorbent resilient flexible material operating within a surface cleaning device as disclosed in this patent, may be regenerated or rinsed off to rid it from the contaminants or dirt accumulated from contacting the cleaning surface prior to recurring contact with a surface being cleaned during the cleaning cycle ofthe cleaning device, such as by applying a rinsing fluid using liquid applicators along the passing absorbent resilient flexible material at a certain convenient predefined position that may be within or not within an enclosure, and before the absorbent resilient flexible material passes via a liquid urging means, before re-emerging to recur contact with the cleaning surlhcc. Another)ncans to regenerate the passing absorbent resilient flexible material may be done by adapting the liquid applicators operating in the cleaning device to apply a clean fluid onto the cleaning surface prior to the absorbent resilient flexible material working within the cleaning device collects the cleaning fluid from the cleaning surface, leaving the cleaning surface in a substantially clean and dry state is synonymous to rinsing or regenerating the passing absorbent resilient flexible material to achieve the equivalent result. Other means to regenerate a cleaning element such as the absorbent resilient flexible material using a clean fluid as a rinsing element for the purpose of constantly regenerating or removing contaminant substance collected from a cleaning surface by the cleaning element operating within a cleaning device as disclosed in this patent is equivalent to regenerating the cleaning element for continuous cleaning upon a cleaning surface by the cleaning device and in particular to the regeneration of the cleaning element which makes final or last contact with a cleaning surface across a cleaning width may thus be performed directly to the cleaning element or indirectly and still achieve the same anticipated results.
Preferably, the liquid catchn-ient means enclosure module is provided for the intention of acting as a transitory receive-hold and or rcdirect away waste liquids (generally a mixture olcleaning fluid and contaminants dislodged From the cleaning surface) and debris expelled by the compressing force of the rolling elements sandwiching the passing absorbent resilient flexible material. Preferably, the liquid catchment means enclosure module is a receptacle comprising at least one basin; the basin joined to one or more side-walls, that are capable of holding and retaining a liquid without spilling; one or more side-walls of the basin having one or more means of access, aperture or mouth; the aperture for allowing entry for the continuously passing absorbent resilient flexible material moving or travelling into and out-of the liquid catchment means enclosure module for regeneration; the basin having one or more liquid ports for introduction and evacuation of liquids and debris to and from the liquid eatchment means enclosure module.
Preferably, the liquid ports may further comprise one or more drainage port and liquid inlet port.The liquid inlet port having at least one liquid applicator arranged proximate to the passing absorbent resilient flexible material and configured to discharge a clean fluid onto the entire surface of the passing absorbent resilient flexible material within the Iiçuid catchment means enclosure module.
The liquid applicator may therefore have aplurality of non/c's or spouts made of a series of perforations and may he situated along the liquid applicator. The liquid applicator may be placed within or along the walls of the passageway that leads the passing absorbent resilient flexible material into the rolling elements for regeneration, or a soaking, rinsing and liquid removal cycle using clean fluid, within the liquid catehment means enclosure modult The liquid applicator may squirt, expel, sprinkle, spray or smear clean fluid on the cleaning surface.
The drainage port is arranged to remove liquid and debris expelled from the porous compliant body of the passing absorbent resilient flexible material by the compression force of the rolling elements, and sending the expelled mixture of clean fluid and waste liquids and debris in a direction away from the liquid catchment means enclosure module. The liquid inlet port is arranged to deliver clean fluid into the liquid catchment means enclosure module thru to the nozzles of the liquid applicator. Preferably, contamination of the clean fluid delivered to the liquid catehment means enclosure module is prevented by providing a separate clean fluid storage container and a separate waste liquid storage container so that clean fluid may be received orn a direction away from the liquid catchment means enclosure module through conduits fluidly connected to the clean fluid storage container within the chassis or away from the chassis of the cleaning device. Thus, conduits may be fluidly connected via the drainage ports from the liquid eatchment means enclosure module and running to waste liquid storage container fixed within the chassis for temporary storage of the waste liquid expelled by the action of the rolling elements against the passing absorbent resilient flexible material, and the waste liquid storage container could be emptied periodically. Similarly, the clean fluid storage container could be refilled periodically by a user for the delivery of clean fluid via conduits to the liquid eatchment means enclosure module. Thus, a separated clean fluid storage container and waste liquid storage container may be configured to be removable from the chassis by a user so that the clean fluid storage container may filled by, and for the waste liquid storage container to be emptied by the user.
Thus, liquid and debris transporting conduits are fluidly connected between the clean fluid storage container and the liquid catchment means enclosure module may deliver clean fluid to the passing absorbent resilient flexible material via the liquid inlet port and to the nozzles of the liquid applicator, * while conduits fluidly connected to the waste jquid storage container and the liquid catchment means enclosure module may receive waste liquids via the drainage ports for disposal away from the liquid catchment means enclosure module. The conduits may be fluidly connectable and disconnect-able to the clean fluid storage container and waste liquid storage container via easy releasable and connector means and sealing valves on the ports of the clean fluid storage container and waste liquid storage container's walls or such ports on the closure lids.
However, conduits fluidly connected between the liquid catchment means enclosure module and a clean fluid source or clean fluid storage container may be situated away from the chassis thus conduits may run to and fro for delivery of dean fluid via flexible conduits extending from the liquid catchment means enclosure module of the chassis. Similarly conduits fluidly connected between the liquid catchment means enclosure module and a waste liquid storage container away from the chassis may run to and fro for removal and disposal of waste liquid via flexible conduits extending from the liquid catebment means enclosure module and away from the chassis, Pumping means may be used to deliver and clean fluid via the liquid inlet port into the liquid catchment means enclosure module for interaction with the passing absorbent resilient flexible material. thru the liquid discharging nozzles of the liquid applicator.
PrelerabL, the chassis of the cleaning device has separate tanks or liquid containers for storing and fresh cleaning fluid and spent or waste liquids collected from the surface being cleaned. Preferably, the waste liquid storage container and clean fluid storage container are separate so that cross contamination of the cleaning fluid by the waste liquid is prevented.
In certain embodiments of the above aspect, the separate waste liquid storage container and clean fluid storage container may be flexible liquid containers that are collapsible and housed together in a rigid volume, so that maximum volume ofcleaning fluid is able carried or transported by the cleaning device, wherein, as the cleaning fluid is depleted from the flexible clean fluid storage container, a reciprocating action of the volume of the depleting cleaning fluid from the clean fluid storage container is replaced or exchanged into the adjacently increasing volume of the flexible waste liquid storage container held therewith as more spent or waste liquid consisting of spent cleaning fluid and dislodged contaminants is collected from Ui9 cleaning surface. One advantage of this collapsible aspect oF the cleati fluid storage container and the waste fiquid storage container, is that in smaller embodiments of the cleaning device herein, particularly, with the hand-held arid or palm-sized version of the cleaning device, maximum usage of space within the monocoque or chassis of the cleaning device may be maintained.
In certain embodiments of the above aspects, the cleaning fluid comprises water and or any one of cleaning agent additives such as surfactants, soap, solvent, disinfectant, fragrance, emulsifier, drying agent, abrasive particles, bleach and antibacterial; cleaning agent additives may also be added to the cleaning fluid by fluidly inserting or introducing the cleaning agent additives line or pipe from a cleaning agent additives storage reservoir, and into the line of the clean fluid to create a cleaning fluid prior to being expelled at the first cleaning region. The supply of clean fluid such as water, may be drawn a storage reservoir, or container attached to the chassis and configured for separate shampooing or rinsing applications by interrupting the line of the water before reaching the nozzles thru dispensing small doses of soap from a soap container when required or via automatic ratio setting. so that the clean fluid in the storage reservoir attached to the chassis remains pure and can be used for either scrubbing or rinsing applications. Alternatively, the cleaning fluid maybe recirculated (recycled) and the dislodged dirt and debris removed by conventional filters or other means, saving soap and clean fluid consumption. Thereto, soap from a soap container can be administered as required to the water by intercepting the line or conduit of water before it reaches the liquid applicators at the first cleaning region. Thus when necessary, plain or pure water can be used for rinsing and also in other processes in parts within the cleaning device, and a soapy water solution or cleaning fluid can be used for scrubbing the surface being cleaned by the cleaning device during operation.
The supply of clean fluid such as water, may be drawn via conduits from a continuous source e.g., a tire hydrant, a domestic water tap located away from the chassis and connected to the chassis via an interface and the water directed to become configured for separate shampooing or rinsing applications thru interrupting the line of the water before reaching the liquid applicators at the first cleaning region and by dispensing small doses of soap from a soap container when required (or due to automatically set programme). so that the clean fluid from the external source away from the chassis remains pure or plain and can be used for eitlwc scrubbing or rinsing applications or in other parts and processes taking place within the chassis of the cleaning device during operation.
Cleaning agent additives may be in liquid or powder or gaseous form and introducible into the clean fluid in a certain dosage that may be via actuator links controllable by a user of the cleaning device electronically thru switches and automatic soap concentration sensors and programs setting or manually through mechanical means such as levers and or gravity via fluid valves.
One advantage olthe cleaning device is that a single self-contained device performs dirt and debris collection, washing and scrubbing and drying the surface in a single pass over a surface using the cleaning device herein.
Another advantage of the cleaning device is that the contamination of a cleaning liquid is prevented by providing separate flexible clean fluid storage container and waste liquid storage container.
A vital health advantage is that hazardous mic.robial contaminants and substances collected from a cleaning surliKe by the continuously sterilized and regenerating absorbent resilient tiexihle material is segregated and contained separately therein for safe disposal and without the hazardous contents regaining access to the cleaning surface, whereas prior art wet cleaning use stationary passive ridges, scraping elements or squcegees that continually drag and smear hazardous contaminants and bacteria across a cleaning surface and diflèrent premises.
Another advantage of the cleaning device is that the watertight collapsible clean fluid storage container and waste liquid storage container maximise volume thereby reducing the overall size and weight of the cleaning device, and also maximising for extra extended surface cleaning capabilities.
Rigid watertight clean fluid storage container and waste liquid storage container may be utilizable also.
In a certain embodiment, pumping means may also he used to deliver and discharge a gaseous substance into the liquid catchmcni means enclosure nodule for interaction with the passing absorbent resilient flexible material. Pumping.meaus may also be used to remove waste liquids, and or gaseous substance away from the liquid catchnient means enclosure module of the passing absorbent resilient flexible material. Thus, conduits may be contigured to deliver and discharge various other substances such as a gas to the liquid catchment means enclosure module. The gas may be from a pumping device, suctioning or a blowing device or a gas volume container. The gas may also be a cleaning agent, or a liquid cleaning agent mixed with a gas under pressure. The cleaning agent may also be a mixture of a gas and a liquid. The gas may also be a steam.
Preferably, the aperture of the liquid catchment means enclosure module may be in a substantially symmetric balanced arrangement and essentially positioned away from the plane of the basin of the liquid catebment means enclosure module. Preferably, the mouth of the aperture may have a lead-in channel or passageway for allowing smooth entry for the regeneration of the ronhinuously passing absorbent resilient flexible material. Preferably, the liquid catehment means enclosure module may be provided at least one or more deflector flange. tongue, rib or liii, whereby such a deflector flange is a narrow continuous protrusion extending From the inner walls of passageway to submissively touching the passing absorbent resilient flexible material; and the deflector flange arranged to contain, and or redirect liquids expelled by the rolling elements from returning to the passageway or going back or towards the aperture of the incoming or outgoing absorbent resilient flexible material; but instead to direct the expelled liquids towards the basin and drainage ports for disposal; by utilizing successive deflector flanges that provide dams which prevent the expelled and other liquids from passing beyond the deflector flanges in the direction opposing the passing absorbent resilient flexible material, and also regardless of the direction at which the passing absorbent resilient flexible material moves. Thus, liquids are effectively kept away from escaping thru the mouth of the aperture due to less flexing of the deflector flange as the deflector flange may be flexibly resilient to a certain degree, or can be submissively bendable by contact-motional force, therein bending at whichever direction the absorbent resilient flexible material passes by.
In some embodiment of the above aspect, such a deflector flange may be Y-shaped, with the single stem of the V adjoined to the walls of the liquid catchment means enclosure module so that when one end of the protruding pair flanges ol the Y-shped deflector flange is pulled towards one direction by the passing absorbent resilient flexible material, the other of the paired flanges of the V-shaped deflector flange follow, bulls substantially staggered by the distance between the ends of the paired flanges, thereby maintaining a posture that compensates the distance ofthe pull ofthe other Y-flange, thereby still securing the liquids within the liquid catchrnent means enclosure module. In such an embodiment, the end-tops, endpoints, tips or edges of the two V-shaped flanges may be stiffer than the slightly more flexible single bottom stem flange support that is attached to the side walls within the passageway of the passing absorbent resilient flexible material. Thus it may be even possible to place rolling components on the edges of the two protruding Y'.shaped flanges. It may therefore be possible to place drainage ports, and or the liquid applicator or even miniaturised electrical devices such as sensors device, microbial screener that self-clean, placed within the compartmentalised chamber formed in-between by (lie pair of protruding flanges of the Y-shaped deflector flange. Such devices may be placed at the intersection where the paired flanges forming the Y meet. tn yet another embodiment, the deflector flange may be configured to hold the liquids together when using the cleaning device on a vertical plane by adjusting the slanting of the submissive deflector flange thru contact-motional force of passing the ahsorb«=t resilient flexible material at a direction opposite the three of gravity when using the cleaning device on a slope or vertical plane. A gravity sensor switch means that may have a toppling or swaying weight connected to an electric circuit may be used to change the direction that the absorbent resilient flexible material moves at so that a direction opposite to the gravitational pull of the liquids when using the device in a vertical plane is attained. In such an embodiment, it may be ideal to position the drainage port at the intersection where the deflector flange meets the walls of the passageway of the passing absorbent resilient flexible material.
Preferably, the liquids expelled by the rolling elements may also reach the basin of the liquid catchment means enclosure module via gravitational force. It may therefore be of essence to place the drainage port, the nozzles oldie liquid applicator of the liquid inlet port strategically to ensure that the different liquids do not flood or mix in the liquid catchment means enclosure module. For example, the drainage port may be strategically placed at either sides of the intersection where the deflector flange mects the walls of the passageway, whereas the nozzles of the liquid applicator may be placed at a position stepped away from the plane dl the passageway that corresponds that of the basin.
Similarly, dellector flange may he made ofa rigid material. and joined to the side-walls of the basin that forms the liquid catchment means enclosure module. Thus, units, subdivisions, partitions or compartments may be respectively formed in this way within the passageway and the basin of the liquid catehment means enclosure module, forming a volume of at least one compartment. The compartment formed is exposed or open on at least one side. The open side of the compartment is the side along that of the plane which the absorbent resilient flexible material passes during use via the aperture. Thus, the edge at the open side of the formed compartment is relatively disposed at a substantially equivalent level as the plane of the mouth of the aperture for ease of the continuous passing absorbent resilient flexible material in and out of the liquid catchment means enclosure module. Thus, the bare or exposed edges of the deflector flange forming the compartment are on one or more sides of the compartment, and as the passing absorbent resilient flexible material travels past the compartmenL the exposed edges of the formed compartment are engulfed or covered by and due to the properties of the absorbent resilient flexible material, which subsequently encloses the edges of the compartment's opening. thereby formthg at a sealing attribute within the edges of the compartment. The sealing attribute makes the formed volume in a compartment enclosed or walled in. The numbers of sealing attributes depend upon the amount of dividing deflector flange forming more compartments. The sealing attribute may also act as an inhibiting element that hinders liquids escaping from the compartment. An added advantage of the formed sealing attribute is that it may also act as an inhibiting element that hinders liquids gases or other substances delivered, or in the compartment from escaping. The sealing attribute may also separate liquids so that a certain liquid may not mix or contaminate a neighbouring liquid or gas in another compartment of the liquid eatchment means enclosure module. Another advantage of the sealing attribute may also be to separate gases so that a gas may not mix or contaminate with a neighbouring gas or liquid between compartments of the Liquid catchment means enclosure module. The edge of the formed compartment may be configured to have tubular lip, rounded curve or rotatable cylinder bearings that press against the passing absorbent resilient flexible material so that substances such as liquid or gases from a one compartment are prevented from being carried or crossed-over to an adjacent compartment. An advantage of adjoining deflector flange in order to form ompartment is that the surface cleaning device can operate alonga vertical plane and ewen whilst upside down without any liquids spillingout from the device. Another advantage of this arrangement is that compartments dealing with contaminated liquid and substances may not mix or communicate with other compartments that are already free from contaminated liquids and substances thereof. Thus, clean fluid and cleaning agent additives and processes thereof may operate in respective compartments according or following a certain predefined systematic cleaning cyclic stages the passing absorbent resilient flexible material undergoes while passing such compartments and subsequently exiting the other workings of the liquid catchrnent means enclosure module in a regenerated state. Such operations within the compartments may be operated manually using an actuator switch or by using other using pre-programmed means.
In a certain embodiment, an advantage of the sealing attribute along the enclosure of the compartment by use of the continuously passing absorbent resilient flexible material is that it may therefore be possible to apply a suction or blowing Force within the enclisure of the compartment in order to suck or blow debris and liquid away from the absorbent resilient flexible material. The suctioning or blowing force may connected to a vacuuming or fanning means via a hollow conduit fluidly connected between the compartment and a container for holding waste within the cleaning device or away from the cleaning device. Thus a plenum of high pressure may be formed independently within a particular individual compartment without interrupting or affecting a neighbouring or adjacent compartment. Thus, it may be possible to apply a particular or certain fluid, a suctioning and, or, a blowing force or a brush inside such a compartment for interaction with the continuously passing absorbent resilient flexible material in use, without affecting the neighbouring compartment within the liquid catchment means enclosure module. It may even be possible to insert a device such as a bacterium swabbing and incubating device, a sump sediment sludge sampling toxicity analyser or sample collecting apparatus, or a self-cleaning microbial screening device inside one of the respective compartments of the liquid catchment means enclosure module of the cleaning device disclosed herein.
In yet another embodiment of the above aspect, it may be possible to have more than one rolling elements in a single liquid catchment means enclosure module that has separate compartments. Thus, more than one pair of rolling elements may be situated within the liquid catchment means enclosure module. The rolling elements may be ideally placed on the edges of the dividing wall formed by the deflector flange that make the separate independent compartments. An advantage of this arrangement is that different liquids and gases or waste liquids are kept separate within their separate compartments, thereby reducing the chances of contamination or transfer of impurities from one compartment to another. Another advantage is that different liquids or gases can be applied for interaction with the passing absorbent resilient flexible material, and still be able to be deposited back into their respective compartments, or without leaving their respective compartments, which is worthwhile to ensure continuous recycling of the used liquids being applied in their respectively sealed compartments, thereby saving energy and financial resources.
In another embodiment of the above aspect, the arrangement and separate operations thereof the compartments within the liquid catchment means enclosure module, may be repeated or mirrored symmetrically and including the operations and structure af their respective predefined systematic cleaning stages along the either sides or faces.f the passing absorbent resilient flexible material.
Prekrably, the edges of the mouth of the aperture and deflector flange's of the formed compartments may have at least one tubular lip, rounded curve or rotatable cylinder bearings so that the least amount of friction and resistance is experienced between the passing absorbent resilient flexible material and the against the edges of the compartments and passageway along the mouth of the aperture of liquid catchment means enclosure module at all times. This action also provides for lesser wear and tear of the absorbent resilient flexible material as it is continually stretched and compressed as it encounters the rolling elements in use within the liquid catchment means enclosure module. It also helps to reduce drag and motor load, thereby saving electrical resources thus increases efficiency and extends motor and bearing longevities, and that of the cleaning device as a whole. The tubular lip, rounded curve or rotatable cylinder bearing also act as a sealing attribute between compartments and respective operations as described above and in other embodiments of this patent disclosure. The tubular lip, rounded curve or rotatable cylinder bearing ma: be ideally placed on the open side of the edges of the compartments and the mouth 9f the aperture of liquid catchment means enclosure module for reducing friction against the absorbent resilient flexible material as it enters and exits the liquid catchiient means enclosure module. Such or other friction inhibiting elements may be placed in any other positions deemed necessary so as to reduce the occurrence of such friction. An advantage of this arrangement is that different liquids and gases are kept separate within their individual compartments, thereby reducing the chances of contamination or transfer of impurities and contaminants from one compartment to another and to, or back to the surface being cleaned by the cleaning device. Another advantage is that different liquids or gases can be applied for interaction with the passing absorbent resilient flexible material within individual compartment(s), thereby being
-S
prevented from leaving such compartment. as the substances are deposited back into their respective compartment of origin for other resource saving purposes such as recycling.
Preferably, the arrangement of the nozzles of the liquid applicator with respect to the passing absorbent resilient flexible material travelling towards the rolling elements causes the location of the nozzles to precede the rolling elements. Preferably, the arrangement of the nozzles and compartment is mirrored symmetrically along the axes of the rolling elements. The reason for mirroring the nozzles and compartment along the axes of the roll inglements symmetrically to the opposite side is so that at whichever direction the passing absorbent resilient flexible material travels at, it can be regenerated adequately by either one of the nozzles prior to the absorbent resilient flexible material meeting the rolling elements. A switchover means or a mechanical reciprocating means that stops the workings of one section of the regenerating components within the liquid catchment means enclosure module whilst the same oppositely mirrored' components of the other section operate and vice versa maybe used. That is, when the absorbent resilient flexible material is revolving in a circular motion and at a clockwise direction, and the line that connects the axis of the rolling elements also divides the circle in two equal portions from the twelve o'clock to the six o'clock quadrant points, and both of these portions having equivalently mirrored regenerating components adjacent to both sides of the rolling elements i.e. the nozzles, drainage port, compartment and any other components and devices therein, so that as the absorbent resilient flexible material travels at the clockwise direction, functions and operations of the regenerating components on the left hand side of the equally divided circle operate in ordcr to continuously regenerate the passing absorbent resilient flexible material, whilst the functions and operations of the regenerating cmponents on the right hand side of the equally divided circle do not operate. On the other hand, when the absorbent resilient flexible material is revolving in an anticlockwise direction, the functions and operations of the regenerating components on the right hand side of the equally divided circle operate in order to continuously regenerate the passing absorbent resilient flexible material, whilst the functions and operations of the regenerating components on the left hand side of the equally divided circle do not operate.
Thus an alternating or reciprocating switchover means that switches on and off the regenerating components functioning and operations within a liquid catchnient means enclosure module depending on the direction of the passing absorbent resilient flexible material takes may be used.
However, the cleaning device may work adequately without the multidirectional revolving absorbent resilient flexible material, that is, the cleaning device may function sufficiently with a unidirectional absorbent resilient flexible material.
In a certain embodiment, (lie advantage of kaving the capability of the regenerating components within the liquid catchment means enclosure module being able to reciprocate functions and operations as described above using the equally divided circle is that in an embodiment where the absorbent resilient flexible material is a partial block e.g. a square block, and that is not circularly rotatable, the reciprocating mechanisms of the regenerating components within the liquid catchment means enclosure module may still adequately regenerate the entire piece of absorbent resilient flexible material block cleaning a surface, by either; the block moving to and fro thru a stationary liquid catchment means enclosure module or a movable liquid catchment means enclosure module moving to and fro along a stationary block for regeneration. Such movements between the block and the movable liquid catchment means enclosure module may be performable on a rack and pinion linear carriage means.
Preferabry, along the surface of the basin there may be provided a rigid contiguous projection ridge or central wall. The central wall extends along and across from the basin's surface area to Joining with the surrounding side-walls. Thus, the central wall essentally divides the liquid catchment means enclosure module into two symmetrical or non-symmetrical sides or portions so that when liquid is urged-oFf or expelled from the passing absorbent resilient flexible material by the force of the rolling elements, the urged-otT liquid is stayed in one side or portion of the divided liquid catchment means enclosure module and hindered from gaining access to the other side or portion of the liquid catchment means enclosure module because of the action of division created by the central wall. The central wall may have a flexible seal at the edge so as to be touching lightly with the surface of the rolling elements. The flexible seal at the edge of the central wall denies liquids adhered to the rolling elements thru viscosity from gaining access to the other side or portion of the divided liquid eatchment means enclosure module. The central wall may be located below, above, sideways or diagonal to any type of liquid urging means.
Preferably, the central wall prevents waste liquids expelled from the absorbent resilient flexible material by the compression of the rolling elements from one side of the basin of the liquid catchment means enclosure module from reaching or gaining acces? to the other side or basin of the liquid catchrnent means enclosure module therein ausing contamination of the regenerated part of the passing absorbent resilient flexible material that is already met the rolling elements and before exiting the liquid catchment means enclosure module. That is, as the absorbent resilient flexible material continuously passes via the liquid catebment means enclosure module, undergoing regeneration that may include soaking and rinsing in separate compartments and before encountering the rolling elements through which all spent liquids collected from the cleaning surface (and from the compartments therein) have to be urged-off and kept separated (by the divisive action of the central wall) from going or reaching-on past the regenerated part of the passing absorbent resilient flexible material that has already encountered the rolling elements. The compression of the rolling elements causes the passing absorbent resilient flexible material to become so reduced in width e.g., to less than 10% of the original and additional soaked size, such that liquids held within the passing absorbent resilient flexible material may not manage to cross beyond the point of compression (caused by the meeting of the rolling elements) and into the other part past the compression, but for the passing absorbent resilient flexible material to conform to being effectively wringed so that spent liquids urged-off at this point remain only within one portion of the basin where the degenerated absorbent resilient flexible material is transjorily held before encountering the rolling elements.
Thereto, the central wall prevents the 5pm1 liquids urged-off from the absorbent resilient flexible material by the compression oithe rolling elements gaining access towards the regenerated part of the passing absorbent resilient flexible material that is now semidry or dry, clean and free from spent liquids. The central wall ensures that the absorbent resilient flexible material remains semidry or dry, clean and ready to recur contact with the surface being cleaned, so that during cleaning, the absorbent resilient Ilexible material goes thru a cycle of collecting or absorbing spent liquids from a cleaning surface, before passing via the rolling elements for the spent liquids held within the absorbent resilient flexible material to be urged-off, and the cycle continues thereby ensuring that the cleaning device leaves the surface being cleaned in a clean and dry state.
Thus, the central wall forms an impermeable barrier that essentially divides, hinders and or separates the liquid catchment means enclosure module in two parts or portions; one portion for holding the part of the passing absorbent resilient flexible material whilst in a degenerated state; and the other portion for holding the passing absorbent resilient flexible material in a regenerated state, and before the cycle or collecting liquids lioni a cleaning surface recurs. One main advantage of having the dividing central wall is that the cleaning device can opcrate without contaminating surfaces with previously collected waste liquids held, settling or in transit within the liquid catchnient means enclosure module. Another advantage of the central wall is that the cleaning device may be used on different planes or surface levels, such as slanting, vertical and evcn upside-down surfaces. A fundamental advantage of the above aspect is to prevent hazardous microbial substances collected from a cleaning surface from being dragged or smeared across the cleaning surface as it is with prior art wet cleaning apparatus, as such microbial substances are collected from the cleaning surface by the continuously freshly sterilized absorbent resilient flexible material of the cleaning device disclosed herein, segregating the contaminants that are safely then disposed of. In certain embodiments of the above aspect, there may be provided arrangements for one or more liquid urging means and one or more central walls within the liquid catchment means enclosure module, and wherein such central walls being positioned bordering along where the liquid urging means operates, and separating the passing absorbent resilient flexible material between the degenerated part and regenerated part thereby hindering liquids urged-off by the rolling elements regaining access or contact back to the regenerated part of the passing absorbent resilient flexible maleriai; wherein such liquid urging means may be; rolling elements, clamping elements or stationary vacuuming and or blowing elements that may be adjacently positioned below, above, diagonally or sideways of the position of the central walls.
Preferably, the central wall forms an impermeable seal between the side-walls and the central wall; whereby the occurring compression along the meeting point of the rolling elements forms a tight sealing as the absorbent resilient flexible material passes between the rolling elements, because the -S.
rolling elements preferably have resilient coating to form the compressional properties needed to cause a tight sealing essentially causing that portion of the basin to become sealed off from the rest of the liquid catchment means enclosure module, ensuring that liquids and or gases therein remain therein.
Occasionally when using the self-regenerating surface c'eaning device, a user may come across portions of a cleaning surface that may have ppon larger concentrations of contaminants such as an inky substance, ordinary soiling or a caked spot oldirt or mud smudges. In such an occurrence, the absorbent resilient flexible material may have to become rinsed and or hushed using more clean fluid so that the contaminant can be successfully removed or rinsed away from the absorbent resilient flexible material. Increasing or decreasing rinsing fluid in relation to the level of contaminating particles suspended within the absorbent resilient flexible material and surrounding liquids may be controlled by using detection means; wherein detection means trigger an increase of bursts of rinsing fluid being ejected against the passing absorbent resilient flexible material whenever the concentration or particulate content within the ejected liquid suspension appreciates. On the other hand, triggering action decreases the rinsing fluid whenever the level or concentration of the particulate content suspended within the liquid depreciates. Detection means may be positioned around the area where the liquid solution drains after being expelled from the absorbent resilient flexible material by the liquid urging means. In some embodiments, the level of increase or decrease of the rinsing fluid may be determined manually via swiLhes that increase or decrease thc rinsing fluid depending on the appearance of the claned surface. Further to the above aspect, it may be necessary to shake the passing absorbent resilient flexible material at the area around where the burst of rinsing fluid is discharged upon; wherein shaking the absorbent resilient flexible material may be done by utilizing a vibrating means. The vibrating means may be in a form of an irregularly shaped projection on a rotating shaft, wheel, cam or rod; wherein the irregular body may be of any cross-sectional shape along the axis of the shaft, such as elliptical, triangular, hexagonal or squarely shaped may be stretched along the longitudinal length of the shaft in an oscillating pattern. The vibrating means may be &eely rotated by the passing velocity of the absorbent resilient flexible material, and the rod holding the irregular body rotatably secured within recessed holes along passageway of the liquid eatchment means enclosure module, or may be driven by motorised drive means. The vibrating means may produce vibrations such as in orbital rhythms on one or more sides or faces of the passing absorbent resilient flexible material so that the action quickly causes held particles and debris to loosen and or dislodge from the passing absorbent resilient flexible material that is simultaneously flushed. Other vibrating means such as an ultra (sonic) sound emitter may be implemented hercinto achieve the desired purpose above.
In another embodiment of the above aspect, the cleaning device may further have a sealable waste-liquid extension volume tray attachable to the liquid catchment means enclosure module. The waste-liquid extension volume tray may be positioned beneath the compartments. The waste-liquid extension volume tray beneath the compartments and may extend the length and width of the size of the liquid catchment means enclosure module, and may have furrows and or dividing ridges moulded and conilgured to retain and prevent liquid from regressing back, in a similar manner as one-way valves. The waste-liquid extension volume tray may further be divided symmetrically along the perpendicular centre of the central wall, so that waste liquid expelled from the rolling elements does not contaminate the adjacent part or portion of the divided liquid catchment means enclosure module.
This arrangement allows that at whichever direction the absorbent resilient flexible material travels thru the liquid catchmcnt means enclosure module at, waste liquid cannot make its way to the regenerated or wrung portion of the passing absorbent resilient flexible material or past the dividing central wall bordering both dividing walls, including the perpendicular centrally adjacent waste-liquid extension solume trays separator. Thus, the cleaning device can be used on a vertical or upside down surface without the liquids p6ciring or escaping towards the rolling elements. The waste-liquid extension volume tray beneath the compartments may have drainage ports for disposal of the waste liquid and may also have liquid inlet ports for introduction of clean fluid. The waste-liquid extension volume tray beneath the compartments may be reached by lifting off the portion with the integrated compartments above. The peripheral edge ends of the portion with the separate joined compartments fits and sits snugly with the peripheral border edge rim end of the waste-liquid extension volume tray. A resilient liquid inhibiting lining may be positioned in between the two sections of the peripheral border edge to keep the unit sealed during use and storage.
In yet another cmbodiment, the liquid catchment means enclosure module maybe hydrodynamically configured to have a gyroscopically stabilised basin. The gyroscopically stabilised basin may keep liquids in an upright position when the cleaning device is used to clean surface planes that are vertical or upside-down position. Flexible liquid drainage conduits may be suspended within the gyroscopically stahilised basin for disposal of the collected waste fluid held in the stabilizing basin Preferably, the enclosure of the liquid catchment means enclosure module may have at least one lid, casing, covering element or covering means that surrounds the peripheral edge of the liquid catchment means enclosure module. The covering element partly or partially surrounds the periphery of the liquid catchment means enclosure module where the passing absorbent resilient flexible material meets the mouth of the aperture. The covering element is provided with a lining element or a rubber sealing that keeps the corresponding edges of the covering element section and that of the basin's section mated, thus substantially sealed, thereby helping to contain the fluids and or gases issued within the entire workings inside the liquid eatchment means enclosure module.
Preferably, the covering element is connectable to the section of the chassis that includes the basin section of the liquid catchment means enclosure module via a hinging means or suitable locking means. The hinging means or suitable locking means may have a click-on-click-off locking means or a push-pull opening and locking means. The locking means provides access via the covering element and into the area within the liquid catehment means enclosjre module whenever the need such as to empty, clean or change or install a componInt part working within the liquid catchment means enclosure module arises. The locking means and hinging means also ensures that the covering element section and basin section align adequately.
In another embodiment, the liquid catchment means enclosure module and that of the covering element may be formed or built-in from, as a contiguous body that is fully sealed, with at least one port for access of pressurised liquid or gas medium, for example, pressurised gas forming a plenum within enclosure for vigorous interaction and removal of impurities from the passing absorbent resilient flexible material.
In another embodiment, the covering element may be positioned in a different position, for example, the covering element in the preferred arrangement may be situated on the side walls of the liquid catchment means enclosure module. Also, in another embodiment of the above aspect of the covering element, the structural arrangement and operations of the liquid catchment means enclosure module and compartments with their various operations thereof, may be repeated or mirrored symmetrically along the cross-section oithe passing absorbnt resilient flexible material, thereby regenerating the continuously passing absorbent resilient flexible material on either sides or faces as it continuously enters and exits the liquid catchment means enclosure module.
Preferably, the covering element may have tubular bearings fixed on the inner side or surface of the covering element that would otherwise frictionally engage with the passing absorbent resilient flexible material. Preferably, the edge surrounding the covering element correspondingly mates with the peripheral edge surrounding the section that comprises the basin of the liquid catchment means enclosure module, whereby the resilient rubber sealing is positioned so as to be sandwiched by the two portions once they are connected. Once the two portions are connected or shut together, partial access is left open at the mouth of the aperture for the continuous passing absorbent resilient flexible material in use into the liquid catchment means enclosure module. Once the covering element and the basin portion are fastened together, the compressing forces acting on the resilient rubber sealing at the mouth of the aperture helping to ensure that the covering element and the basin section are compactly fastened together, and that the liquid catchmeth means enclosure module remain shut and its contents thereof are in containment. The collaboration of the pivotal hinging means and locking means between the covering element and the basin, sandwich the resilient rubber sealing firmly, helping to ensure that the workings within the liquid catehments means enclosure have ample operating space once the rubber sealing is compressed to a certain degree, and at that the same time letting the absorbent resilient flexible material to continuously pass thru with ease, uniformly and being correctly compressed at the receptive mouth of the aperture, and via the submissive deflector flange and to the rolling elements, within the liquid catchment means enclosure module, thereby essentially securely and hygienically sealing the contents inside the liquid catchment means enclosure module from escaping in liquid, debris or odour form. Thus, an advantage of securing the covering element in this way is that it acts as a sealing attribute whereby all liquids and debris can be safely contained within the liquid catchment means enclosure module. Also, securing the covering element in this manner allows freedom and peace ofmind to the user when operating the surface cleaning device and or during traiislèr from one place to another and during transport or storage. Also another advantage of keeping the covering element securely shut is that the surface cleaning device can be used in awkward planes such as slanted, diagonal.ertically or upside down whilst safely retaining and containing the waste liquids and debris inside the liquid catchment means enclosure module without escape or leakages. Also contaminated liquids and debris are kept in containment at the basin by the concerted cf/on' of deflector flanges within the passageway of the liquid catchment means enclosure module and walls of the compartment, thereby reducing the risk of leaks and bad odours emitting from the enciosure of the liquid eatchment means enclosure module to the surface being cleaned.
In certain embodiments of the above aspcct, the compartments may operate as liquid holding containers, whereby waste liquid and debris collected from the surface is stored before being manually emptied by a user. Thus, some or one of the compartments may be configured for receiving waste liquid and debris from the passing absorbent resilient flexible material and may therefore contain debris and waste liquid. Such compartments may be emptied manually by a user; such compartments may be removable by a user and accessed by lilting open (he covering element.
Preferably, the compartments may be seet as a temporary substance holding containers for containing substances such as a liquid to be applied or be removed from the passing absorbent resilient flexible material. Thus the compartments may be fluidLy connected via conduits to separate clean fluid storage container and waste liquid storage container that are situated within the cleaning device or away or external from the cleaning device. Preferably, the conduits may be fluidly connected to a pumping, suctioning or blowing means for delivery of clean fluid to the compartments within liquid catchment means enclosure module, and the removal of waste liquids and debris away from the entire workings of the liquid catchment means enclosure module. Filters may be strategically positioned at the drainage ports for withholding dirt, sediment and debris from gaining access into the conduits. Such drainage ports may be raised from the plane of the basin where sediments and larger debris is likely to settle. However, it may be possible to have widened drainage port and conduits, hollow enough for efficient transport such larger debris, sediments and waste liquids.
Thus, conduits may be fluidly connected and running from the liquid catchment means enclosure module to separate clean fluid storage container fixed within the chassis for temporary storage of the clean fluid for delivery to interact with Lhe passing absorbent resilient flexible material; the container could be filled periodically by a user. Similarly, conduits may be fluidLy connected and running from the liquid catchment means enclosure module to separate waste liquid storage container fixed within the chassis for temporary storage of the waste liquids and debris expelled from the passing absorbent resilient flexible material: the container could be emptied periodically by a user. Thus to save the user time and a cumbersome moment, the containers could be integrated to avoid a user having to deal with two separate containers. The integrated containers may have easy push-pull locking mechanism for removing the containers and lead-in notches for easy installation. However, conduits extending away from the entire chassis of the cleaning device maybe used to dispose waste liquid in a direction away from the cleaning device. Similarly, conduits extending away from the chassis of the cleaning device may be used to deliver clean fluid to the cleaning device from a clean fluid volume situated away from the chassis of the cleaning device.
Prelerably, the flexible resiliency forces acti between and against the absorbent resilient flexible material, the deflector flange and the covering element along the passageway help to keep the enclosure of the liquid catcliment means enclosure module sealed, yet allowing ease for the continuous passing of the absorbent resilient flexible material in either direction, for example from left to right or vice versa, by means of the pliable compliant receptive elements that may be a combination of flexible two way receptive and submissive lips, ridges or deflector flange and tubular lip, rounded curve or rotatable bearing at the edge of such deflector flanges, surrounding the mouth of the aperture. Such deflector flange may be strategically placed along the compartment edges within liquid catchment means enclosure module. One advantage for this arrangement is to enablethe passing absorbent resilient flexible material to be kept or maintained under a constant pressure whenever it is passing via the entire liquid catchment means enclosure module. Another advantage is that the formed individual compartments may allow different tasks and activities to be carried out separately on the passing absorbent resilient flexible material, that is, various actions may be independently and respectively carried out within a certain compartment, whereby such different tasks may include; spraying, steaming, >iishing, soaking, wringing, blowing, suctioning, introduction of a certain liquid into an independent or separate compartment, for example, water, disinfectant, iodine, chlorine, vinegar, antiseptics, disinfection using an alcohol-based solutions such as non-flammable alcohol vapour in carbon dioxide or NAV-C02, hydrogen peroxide, silver nitrate, iodine, chlorine, steam, bleaching agents and perfume, hydrides etc., can be constantly introduced into individual or separate compartment for specific purposes and intended interactions with the continuously passing absorbent resilient flexible material via the liquid catchment means enclosure module.
In certain embodiments, such and other separate tasks above, that is; brushing, wringing, spraying, blowing, suctioning, steaming, sprinkling a liquid e.g. water, disinfection using a substance such as non-flammable alcohol vapour in carbon dioxide or NAV-C02, silver nitrate, oxide, iodine, chlorine may still be carried out on the passing absorbent resilient flexible material within the liquid catchment means enclosure module that has no partitioning or compartments therein. -ft
Preferably, the resilient compressible forced acting between the engulfed mouth edges of the aperture and the absorbent resilient flexibJe material and once the covering element piece is shut against the basin piece, a certain pressure acting on the sandwiched rubber sealing is maintained via a manual engagement area at a position opposite the hinging or latching means once the covering elements clicked or shut in place making the enclosure of the liquid catchment means enclosure module essentially scaled water-tightly and relatively air-tightly. The covering element may be coupled to a hinging means or quick clipping means that may help a user gain quick access to the inside of the enclosure olthe liquid catchmcnt means enclosure module when a user would like to quickly clear or flush away debris or sediments from the basin of liquid catchment means enclosure module. A latching means would also perform the preferred function of quickly shutting and opening the covering clement. Guide-notches may be positioned in place for leading-in the latching means where the two sections of the basin and covering clement are not permanently hinged. An advantage of having the opening and closing of the covering element against the basin is that it may be easy to gain access or remove or install the absorbent resilient flexible material easily since one roller of the pair of rolling elements is attached on the interior surface of the covering element. Alternatively, the rolling elements may be left fixed within the liquid catchment means enclosure module and the absorbent resilient flexible material may be installed by sliding it in between the rolling elements because of its resilient and compressible properties. Alternatively, a camming arrangement, whereby operation of the camming arrangement moves a connecting member attached to a lewr that when drawn. the rolling elements move apart may be used, so that as the lever is moved to a second position perpendicular to the rolling elements, access to install or remove the absorbent resilient flexible material is achieved with ease. This construction eliminates the need for any electrical or such operative components in the area behind the camming mechanism, though this is not strictly essential and other arrangements for separating the rolling elements may be employed, such as a rack and pinion, worms-screw means arrangement may be used in the same manner above to provide the equivalent result.
Thus, some embodiments, of the cleaning device may further include a detecting unit that comprises a plurality of detectors attached to the chassis and or integrated with the subsystem of the cleaning device and configured to sense, monitor and or detect internal conditions thereby producing electrical signals in response to such conditions; wherein a signal line for communicating detector signal to the main control unit and a controller and or comptroller device incorporated within the main control unit for executing predefined operating modes of the cleaning device in response to such conditions. The detecting unit may produce electrical signals and communicate the electrical signals to the main control unit; wherein individual sensors may perform separate functions, such as; detecting an empty * clean Fluid storage container, detecting an empty rinsing fluid container, detecting a full waste liquid storage container, detecting a flooded or cmty compartment, detecting or measuring to keeping an optimum how, and or level of certain liquid and or gas within compartment at certain standard and mixture and or consistency, detecting low battery power, vacuuming system clogging, detecting efficacy of the cleaning materials and condition of cleaned surface, detecting particulate concentration within liquid suspension or particulate ratio within liquid or gaseous medium, detecting particulate sizes and dregs, detecting the texture of the cleaning surface, detecting dirt on cleaning surface-e.g., mud, detecting cleaning system problems such asjamming of a rotating component such as a brush or gearwheel and or blockage of a gaseous suctioning component, detecting or measuring torque of primary drive means and secondary drive subsystems, detecting or measuring velocity and torque (and compression force) of rolling elements, detecting or measuring velocity of various other cleaning components, detecting inefficient motor dragging and parts needing replacement and or lubrication, detecting current status between AC and DC electrical inputs so as to regulate switches and transformers according to correct or matching current, detecting temperature of the cleaning device, system status, surfaces and ambient air conditions by monitoring of living/non-living microscopic substances, temperature and humidity of the premises being cleaned, and numerous other conditions.
Preferably. the covering element nay be moulded togetiier or blended with at least one handle component. The handle component allows adser to support the cleaning device on a surface being cleaned. Prcfcrably, it may be possible to have a slotting means on the handle component or on covering element for temporarily or permanently inserting or fixing at least one tube-like elongated handle or extension handle element for allowing a user to be able to reach far out, narrowed or high above surface areas that need cleaning using the cleaning device described herein. The user input control unit may be disposed on the surface of the covering element and or handle component with one or more user manipulated actuators disposed on the user input control unit. Buttons, dials and visual lights on the user input control unit are placed conveniently on the handle component and blended to the covering element of the cleaning device. The slotting means for the extension handle element may have a slotting means and command interaction unit for repeating the same commands of the user input control unit displayed the handle component to the extension handle element. The same operational buttons on the covering element of the cleaning device may be repeated on the extension handle element, which is then connected (via slot) into the covering element of surface cleaning device by way of mating elecironie terminals on the extension handle element with those electronic terniinals on the slotting means anS command interaction unit on the covering element of the cleaning device. Physical wire linkage means may be used to send or communicate commands to and from the cleaning device whilst using the extension handle element connection to the cleaning device via the covering element. However, wireless communication means may be used to convey the commands. Such communicating means may be radio wave signals connection means, may be used to send or communicate the same commands to and from the cleaning device and the extension handle element whilst using the extension handle element. Preferably, the extension handle element may be connected and or disconnected from the cleaning device using a quick release click-in and click-off mechanism that latches or locks the extension handle element securely in place. Such a mechanism may have a leverage button conveniently placed at the extension handle element.
Preferably, such a leveraging button is manually actuated. The extension handle element may have the capability to be articular or bendable. This articulation is preferable at the base of the extension handle element closest proximity to the cleaning head of the cleaning device or nearest to the extremity or end opposite the handle portion of the extension pole during use of the cleaning device.
Preferably, the articulation of the extension pole handle Llernent may allow a variety of different surface planes and surfaces to he reached an cleaned by the head of the cleaning device; wherein such surfaces reached and cleaned sufficiently may include and not limited to; fiat surfaces above the height of the user of the cleaning device, swivelling of the cleaning head rotatably attached to the extension handle element so that the cleaning device can easily reach around furniture, baseboards or skirting boards, narrow gaps and tight corners, flat surfaces above a user's height, when cleaning various surfaces iii a domestic or commercial environment. One advantage of the extension handle element having length extendable or adjustable telescopic handle pole or boom provides extra safety by suiting both the user and the cleaning surface, so as to reach various surfaces such as high up window panes, horizontal and or vertical surfaces in narrow spaces and the extendable pole may have pivotal or a rotating neck to, say, 140° degrees for allowing the cleaning device to gain reach such as flat level surfaces above the height of the user.
In alternative embodiments, the extension handle element may be configured to act as both the user's support means fbr the cleaning device upon the cleaning surface and also for supporting other cleaning components of the cleaning devicesuch as waste liquid and debris container tank, clean Iluid container, soap container. suctioning or vacuuming elements, pumping elements, associated conduits and electrical components.
The selttregenerating surface cleaning device may further include one or more illuminating or irradiative element. The irradiative element configured to produce or emit rays of light toward the surface being cleaned by the cleaning device. The irradiative element may also be configured to radiate light within certain components of the cleaning device; wherein such components may include liquid holding and liquid transporting components and chambers wherein the irradiative light may be shone onto such liquids being transported or held within liquid holding containers therein. Irradiative elements may thus emit light toward passing or contained liquids via translucent liquid proof bulbs.
Preferably, the light implemented is UV or Ultraviolet germicidal irradiation that destroys numerous classes of microbial substances. The UV light emitted within the chassis of the cleaning device destroys microbial substances held in liquid or gaseous mediums; wherein such liquids and gaseous mediums may be on transit in conduits oçpipes within the cleaning device or held in storage containers and compartments within the chassis of the cleaning device. In certain embodiments, irradiative light may be used in cleansing waste liquids and gases. In certain embodiments, the cleaning device may possess irradiative element for shining Ultraviolet rays on surfaces being cleaned by the cleaning device. Also, irradiative element may be arranged within the chassis of the cleaning device, such along or inside waste liquid containers, compartments, sump and associated waste liquid conduits. Thus, UV or ultra violet light filters may be used to decontaminate and sterilize and destroy germs inside the waste liquid containers and relative waste conduits. UV filters may also sanitize and decontaminate the absorbent resilient flexible material before or after coming into contact with the cleaning surface.
Irradiative elements may also be positioned to shine UV light towards the cleaning surface; wherein the irradiative component such as a lamp is fixed at the base of the cleaning device and positioned proximate, or facing the cleaning surface. Preferably, the irradiative component is fixed on the cleaning device across the transverse axis of the cleaning device so as to acquire a maximal shining width across a cleaning surface when operating the cleanuig device. The provision of the cleaning device having ultraviolet irradiative clement &r LIV lamps placed along the waste liquid pipes, inside waste liquid containers reservoirs/sumps, and upon the cleaning surface thereby destroying microbial substances by shining ultraviolet rays into the contaminated liquid and debris, and also shining the UV light on the cleaned surface, leaving the cleaning surface sanitized and hygienic. The irradiative element or UV lamps may also be fixed along or within vacuuming chambers, dirt filters and dirt containers, dirt separating chambers, dirt bags, stretch hose, conduits and pipes of the cleaning device so that hazardous microbial substances such as bacteria, fungus and viruses are destroyed before sucked air is released from the cleaning device and sent back into the ambient air of the room being vacuumed using the cleaning device as disclosed herein. The irradiative element is connected to the main control unit for control according to the user requirements.
The chassis of the self-regenerating surface cleaning device may be supported on the cleaning surface via a handle component attached to the chassis. The chassis may further have wheels extending from the lower chassis and in rolling contact with the surf&ce being cleaned. The wheels may be lice-rolling or movable in forward or backward direction or movable in any direction such as submissive swivelling caster wheels. However, in a certain embodiment, one or more wheels may be connected to a drive means to enable forward and backward movement across a surface. In yet a further embodiment of the above aspect of having drive means to enable forward and backward movement, two or more wheels may be connected via a flexible continuous belt loop similar to that of military tank treads or bulldozers for giving large surface friction between the cleaning device and the cleaning surface during cleaning operations. Such an embodiment may be used where the cleaning device is used to clean extra smooth surfaces such as vehicle bodyworks and windows, or vertical and upside down surfaces and wherein such tracks are made from soft materials likes silicone and such like rubber resins.
Preferably, the self.regenerating surface cleaning device has one or more wheels mounted on the base of the cleaning device for rolling contact between the cleaning surface and the cleaning device. The wheels allow the entire cleaning device to be easily transpirted across the surface being cleaned by the cleaning device. Preferably a set of whecls,are mounted on the base in parallel configuration such that when the cleaning device is transported across the cleaning surface, both wheels are in contact with the cleaning surface across the cleaning width and disposed along the transverse axis of' the cleaning device. Preferably, the wheels are in the form of balls and or wheels on swivelling supported axles so that the cleaning device can be arbitrarily moved in any direction across a cleaning surface.
However, when the absorbent resilient flexible material is in an extended position in some other alternative embodiments, the wheels no longer contact the cleaning surface because the absorbent resilient flexible material extends beyond the wheels. Where the cleaning surface has a curved contour, crevice and or step, flexibility of the absorbent resilient flexible material enables the chassis of the cleaning device to mould naturally to the fluctuating cleaning surfaces and to reach gaps and steps in-between the crevices or grout cavity lines on a surface. The advantage of this mechanism over prior art cleaning apparatuses that utilize stiff doctor-blade or squeegee blades is that crevices and or grout-lines and curved contours on cleaning surfaces are inaccessible for cleaning by prior art apparatuses thus harbouring contaminant growth. Preferably, the wheels of the cleaning device may be connected to a lifting and lowering mechanism that cau.es the wheels to extend away or outward from the base of the cleaning device or alternakively cause the wheels of the cleaning device to retract backward or inward into the base of tlic cleaning device. The lifting and lowering mechanism may be connected on a lever so that when the lever is lifted, the wheels of the cleaning device no longer gain contact with the cleaning surface, leaving cleaning components on the first cleaning region and the second cleaning region to lose contact with the cleaning surface. The opposite action of lowering the lever allows the wheels of the cleaning device to regain contact with the surface being cleaned. A certain advantage of this wheel leveraging mechanism is that collecting debris and loose particles using the cleaning device is enhanced, for example, when vacuuming the cleaning surface thereby reducing the gap of the cleaning head and the cleaning surface to increase suction. The lever may be connected to the handle component of the cleaning device and having a switching mechanism that may lock the lever into a position where the wheel remain extended from the cleaning device or retracted into the cleaning device; and such a switch may be automatically controlled instead of being a manual lever. Similarly, the absorbent resilient flexible material may be supported on a pivotally attached member connected rotalablc to the chassis of tie cleaning device so that the absorbent resilient flexible material may be lowered in a4irection away from the chassis in order to gain mutual contact with the cleaning surFace or alternatively lifted away from the cleaning surface and toward the chassis of the cleaning device using a mechanical lever and a locking mechanism; wherein such a mechanical lever may be a mechanical on/off lever, and the lever positioned at a position where the user of the cleaning device can use their foot conveniently to press the nearby lever, wherein the lever is configured to be pressed once for lowering or extending the absorbent resilient flexible material away from the cleaning device, to gain contact with the cleaning surface, and the lever pressed once again to release a locking mechanism on the lever to thereby retract or lift the absorbent resilient flexible material away from the cleaning surface, whilst leaving the rest of base of the cleaning head (with first cleaning region or second cleaning region) section maintaining contact and support from the surface being cleaned. However, the manual lever or switch may be replaced by an electronic actuating on and off switch conveniently positioned at the handle component position for easy automatically extending or retracting the absorbent resilient flexible material during a cleaning cycle when using the cleaning device. One advantage of the above lever mechanism's aspect is to allow the user of the cleaning device the added opportunity of having a single surface cleaning device that provides the flexibility of vacuuming the floor surface, and also washing the floor surface simultaneously or respectively, using a singlt«=urface cleaning device, and without need for manually changing any cleaning head attachments or accessories therein.
In a certain embodiment, the absorbent resilient flexible material may be supported on a mechanically resilient or springy pivoting joint so that gravitational force and pressure from the user on the cleaning device causes the pivoting action on the joint to reflex or adjust accordingly to every curvature of the surface being cleaned, such as a concave, convex, ramp or step appearing across a cleaning surface during a cleaning cycle when whilst using the cleaning device. In some embodiments, the wheels of the cleaning device may contribute to avoiding the premature wear and tear of the cleaning components and or brushes in the first cleaning region and the second cleaning region. Preferably, the arrangement of the wheels causes the absorbent resilient flexible material to follow the wheels over a cleaning surface when transporting the chassis in a forward direction, so as to avoid leaving tracks of the wheels on the cleaning surface.
In a certain embodiment, the motive powerpeeded to drive the various workings of the cleaning components within the chassis of the cleaning device may be derived/borrowed/tapped from the kinetic energy and or velocity force exerted by the back and forth movements (or motive power energy) produced or released by the user of the cleaning device; wherein, gear coupling is used to transfer rotational motive power energy from the wheels of the cleaning device, and then transforming the rotations using series of/or a combination of drive shafts connected to (but not limited to) right-angled intermeshing gearwheels that divert, convert or transform the kinetic energy from the wheels of the cleaning device into different motive applications to work other different mechanical components working within the chassis of the cleaning device. Such different mechanical components may include, the rolling elements, driving the scraping means or brushes, driving piston arms for liquid pumping means to evacuate Uquid from the drainage port and also to deliver liquid to the liquid inlet port and liquid applicator, rotating or revolving the absorbent resilient flexible material, driving belts and sprockets, driving sweeping brushes and mini-dynamos for charging a self-contained power source, etc. In some embodiments. there may be provided rolling means on the lower chassis of the cleaning device for support over a cleaning surface. 1-lowever, movement across a surface may be provided by the force of velocity produced by the cleaning element rubbing against the cleaning surface during operation of the cleaning device by a user. In such an embodiment, there may be lesser need for wheels extendingly fixed under the lower chassis.
In certain embodiments there may be necessary to have means to support cleaning device on steeper planes; wherein the wheels of the cleaning device may be combined with a surface adhesion means so that the cleaning device can withstand gravity while being used on a vertical plane or upside-down plane of an extended cleaning surface; so that magnetic means may be embeddedly fixed on the under chassis or belly' of the cleaning device to be or reach close or touching proximity with cleaning surface or the magnets may be embedded on the wheels of the cleaning device; and the magnets fixed on the underbelly and wheels ofthe cleaning device and are covered with a softer strong material such as leather, sponge or synthetic fibres, so that friction is removed thus avoiding scratching or damage to the cleaning surface thrti abrasion that would otherwise be caused by the exposed magnets rubbing against the cleaning surface. In such an embodiment, the, magnets may be permanently charged to adhere to a metallic cleaning surface; however, the surface adhesion means may comprise electromagnets thai can be prompted or provoted to adhere or otherwise release the cleaning device from the metallic cleaning surface via an on/off switching mechanism.
The base of the cleaning device is a part of the chassis where the cleaning element and relative components of the cleaning device project from the cleaning device exposed, proximate, facing and in contact with cleaning surface as required. Preferably, cleaning components are arranged from the base in the transverse axis perpendicular to the for-aft axis. Preferably, the base is made from a non-rigid material such as rubber and or plastic; however, the base may be made from other rigid materials such as aluminium, metal wood etc. In certain embodiments of the above aspect, the base may be covered with a softer material such as polyurethane, neoprene, nylon, leather or silicone so that the base does not scratch the cleaning surface. Fixing such a softer material onto the base may be donc by vulcanisation, gluing, bonding, cementing, fusion etc. The base may be configured to have a flexible skirt or seal member comprising an outer lip element and an inner lip element, about the exterior of the peripheral chamber, and the seui member in cooperation with the object surface and the negative pressure region between the outer lip element and an inner lip element is developed when connected to a vacuum source so that spent cleaning liquids and contaminants emanating from the agitating actions of the cleaning components causes the spent liquids to become entrained further into the negative pressure region thereby removing the spent cleaning fluid and dislodging contaminants from a cleaning surface thru restriction or narrowing the vacuum application to a small area about the periphery of the base of the cleaning device. The vacuuming means may be fluidly connected (at the first cleaning region) to the base and skirting lip thereof, via conduits that extend to and from the base of the cleaning device and into debris and waste liquid storage container, which may be situaled within the chassis of the cleaning device, or the waste storage container may be situated away from the chassis of the cleaning device; wherein the vacuuming means may comprise a vacuuming source such as a rotary fan motor and having a fixed housing and a rotating shaft extending therefrom, and having a fan impeller configured to move air when rotated about a rotation axis, and the fan impeller being fixed attached to the rotating shaft for rotation about the rotation axis by the fan motor; a housing for housing the fan impeller in a hollow cavity formed therein and for fixedly supporting the motor fixed housing thereon.
To maintain a certain control of suctioning airflow, a portion or sections of the sealing-action provided by the peripheral skirting lip at the base of the first cleaning region may have perforations or gaps at the point where the skirting lip meets the cleaning surface to form a sealed space between the cleaning surface and the skirting lip. These gaps or perforations may be evenly spaced so that only a certain amount of air intake is allowed into the formed space or chamber between the base of the cleaning device and the cleaning surface during suction, allowing the base of the cleaning device not to get stuck on the cleaning surface. Thus, these gaps or perforations allow even suctioning of the air intake through which airflow is allowed via the perforated gaps on skirting lips and into the chamber and further to the fan impeller cavity carrying with it waste liquids and debris at a high velocity, and an air exit port thru which air is expelled out of the cavity when the impeller is rotated, stilt keeping controlled the suctioning pressure sufficiently, for example, at an ideal negative pressure. Thus, the spent cleaning fluid and dislodged debris may be removed by the application of the vacuuming means provided by the vacuuming source to the chaütber extending about the periphery of the base of the cleaning device to create high velocity airflow; wherein high velocity airflow is developed without fear that the cleaning device will be sucked down and become temporarily stuck on the surface being cleaned. The collected spent liquid and waste debris is retained within the cavity by filtering means that only allow air to pass through whilst preventing and retaining the spent liquids and debris from passing. The base may have be a flexible peripheral skirting or lip that acts as a shroud for preventing overspray of contaminants in liquid suspension and spent cleaning fluid from splashing away from the periphery of the base of the cleaning device when cleaning a surface. Preferably, the flexible peripheral skirting may have bridges or divisional walls extending across or cutting thru the base of the cleaning device which maintain contact with the cleaning surface during operation of the cleaning device, so as to provide separate portions (for different cleaning operation such as vacuuming and shampooing simultaneously) and cleaning components such as scrubbing; and wherein the arrangement of the scrubbing element with rcspect to the flexible pcripheral skirting causes the scrubbing element to precede the flexible peripheral skirting over a cleaning surface when transporting the chassis in a forward directiorCNowever, in certain embodiments, the arrangement of the flexible peripheral skirting with respect to the scrubbing element causes the flexible peripheral skirting to precede the scrubbing element over a cleaning surface when transporting the chassis in a forward, back or sideways direction.
The vacuuming for the flekible peripheral skirting may be interposed at the conduit providing the vacuuming means for the first cleaning region so as to provide suction ing for other separate cleaning regions and cleaning components within the base of the cleaning device; wherein suctioning may be provided within certain chambers, conduits and partitions within the cleaning device, for example, providing auctioning for removal of liquids and debris from the liquid catchment means enclosure module. In some embodiments of the above aspect, partial task of the passing absorbent resilient flexible material is to act as a peripheral skirting shroud' that prevents splashing, overspray and spreading of spent cleaning liquids and contaminants emanating from the agitation and spraying actions of the cleaning components across a surface being cicaned by the cleaning device, and also for maintaining or controlling an even degree of negative pressure within the peripheral skirting lip chamber formed by the sealing-action betweçp the contacting of the base of the cleaning device and the surface being cleaned. In certain embodiments of the above aspect, control of the airflow through the chamber of the peripheral skirting lip and the waste liquid and debris storage container may be achieved through (automatic or manual) adjustment clan air inlet or outlet redirection valve fixed therein, also together with the action of a flexible peripheral skirting lip or seal about the peripheral base of the cleaning device.
Pmferably, the cleaning device has a means to seal or keep the base of the cleaning device sealed.
Preferably, one or more base sealing means keeps the absorbent resilient flexible material from constantly being exposed to atmospheric conditions, or from coming into contact with the cleaning surface when not in use. This may be necessary when storing or transporting the cleaning device or when performing a certain cleaning cycle such as vacuuming only without need for any further washing or drying cia cleaning surface.
Preferably, the base sealing means is a removable rigid casing atthe lower chassis area of the cleaning device and having a resilient lining that (may *ireadingly mate or clicks-to-lock) mates with the edge of the base of the cleaning device such that an airtight and or watertight seal is crcated. Suitable latching means for opening and closing the base may be fixed on the base sealing means and or the edge of the base. Alternatively, the base sealing means can be a sliding door attached to the base of the chassis; or a slid-able door/plate that engages to a lever for manual opening and shutting; the sliding door configured to extend to a shut position, and retract to an open position thereby exposing or containing the absorbent resilient flexible material. The mechanisms of the sliding door for base sealing means may be manually operated or electronically operated. The base sealing means may be arranged to partially or fully cover the base of the cleaning device. The base sealing means may be configured to be a slide-able shutter or door that extends from a first open' position and retracts to a second closed or shut' position so that the absorbent resilient flexible material may gain contact with a cleaning surface when the door is at a retracted position, and vice versa, concealed from gaining contact with a cleaning surface when the door is extended or is into a shut position. One advantage of the base sealing means is to keep the cleaning device sanitary by eliminating the possibility of contaminants dirt and debris, and germs froncescaping or being spread around during the time that the cleaning device is not in use by blocking the possibility of leakages and bad odours, thereby keeping the cleaning components within the base sealing means fresh and readied for the next cleaning exercise. The base sealing means may be a sub-casing element.
In certain embodiments, there may be provided a base unit configured to have passive elements such as hooks and or latching mechanisms for attaching the cleaning device to a wall for storage, or for carrying the cleaning device in a carrying case or sub-casing during transport. Thus, one or more base units may be hanged on a wall saving valuable space volume in the cupboard store, thereby reducing clatter and accidents from tripping. The base unit may comprise a fixed unit connected with a household power supply, e.g., an AC power supply outlet. The AC power supply at the base unit may have connection via one or more interface unit to recharge a self-contained power source attached or fixed within the cleaning device, once the cleaning device is attached or hanged onto the base unit to recharge the self-contained power source therein; and the self-contained power source being a battery. Thus, the self-contained power source recharging interface unit may be used to recharge battery using mains electricity via an eIectriel interface unit which correspondingly mates with the electrical interface unit on the cleaning device hanged onto the base unit to recharge the battery therein.
Penultimately, in today's economy, it is not only critical to ensure that a design of a new product is efficient, but crucially that it is; ecological, cost effective, by producing definite manufacturing ready parts or comprehensive and accurate digital prototypes prior to manufacture thereby reducing exposure to costly tooling changes and emitted carbonic emissions during production; plastic mouldings and allied components thereof the cleaning device will be made from readily available and recyclable raw materials; methods to save mains energy resources by implementing devises of devices such as involuntary transitory energy transfers switches for scavenging from solar, micro-multi directional DC current dynamos attached to free rotating elements such as the wheels and relative couplings, step up miniature electrical inverters within the device, and any other feasible sources of free energy would be applied to, for example, recuarge a lithium-ion battery module within the cleaning device.
Thcrewithal, the long felt but unfulfilled need for an improved fully automated surface cleaning device and method thereof has been met. The improved cleaning device and method of the present invention provides automated means for regenerating the cleaning element that comes into the Last or final contact with a cleaning surface by sanitizing, rinsing and removing spent liquid and dislodged contaminants from the cleaning element as the cleaning element continuously collect the spent cleaning fluids and dislodged contaminants from the surface being cleaned by the cleaning device.
This cleaning device and method shall improve surface cleaning technics that would otherwise require users to input various different prior art cleaning apparatuses and subsequent additional various other strenuous manual cleaning steps to a user. Thus, the cleaning device and method as disclosed herein shall improve cleaning surfaces by obviating the need for numerous tedious cleaning steps and or need for different prior art cleaning apparatuses for a user to contend with during a cleaning operation, such as the need to constantly manua'ly change cleaning head attachments, or entire cleaning apparatuses e.g.. the changeover from vacuuming to mopping. Thus, the sell-regenerating surFace cleaning device shall remove arduous tasks and associated consequences such as using strong chemicals and the washing machine at high electricity consuming water temperatures so as to clean the cleaning microfiber clothes, and also the constant disposing and damage to the environment of such disposable cleaning implements. Also, the cleaning device herein shall provide anxiety free-good-emotional-harmony to the user by way of providing quick and efficient surface cleaning service to the user's satisfaction. These and other meritorious features and advantages of the present invention will be more fully appreciated from the following detailed
description, drawings and claims.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT(S) Referring now to the drawings where like reference numerals identify corresponding or similar elements throughout several views, and also for the Lore 101 and aft 110.
With reference to FIG Ito FIG 5 and FIG 8, are schematic layout of the automated mechanism of the cleaning element's regeneration module of the self-regenerating surface cleaning which includes the chassis, the liquid urging means, the liquid catchment means, the liquid delivery and disposal means, relative liquid delivery and disposal respective containers, soap delivery, support and electrical components and circuitry according to the invention is shown in a simplified cross-sectional view portion showing the basic operation and function of the self-regenerating surface cleaning device.
More examples used in the explanations will be disc! osed below about regeneration or rinsing and drying mechanism and processes of the self-regenerating surface cleaning device, and without being construed as limitations to the scope of the invention and rniiflcations thereof The sell-regenerating surface cleaning device or shortly, the cleaning device 10, comprises a chassis 12, at least one roller 14, and roller 16, an absorbent material 18. The chassis 12 has a basin 20, and means to force the absorbent material 18 through roller 14 and roller 16. Means to force the absorbent material 18 through roller 14 and roller 16 is achieved with provision of a drive motor 22. Drive motor 22 is connected to a gearwheel 24, via spindle 25. Gearwheel 24, meshes teeth with gear wheel 26. Gearwheel 26, meshes teeth with gearwheel 28. Gearwheel 26 is joined to roller 14. Gearwheel 28, is joined to roller 16, so that once gearwheel 24, is rotated in the direction as indicated by rotation directional arrows 23, 27 and 29, gearwheel 26, and gearwheel 28, rotate in accordance and together with roller 14. and roller 16 respectively; and rotates gearwheels 26 and 28, into the opposite direction when gearwheel 24, is rotated into the opposite direction to that indicated by rotation directional arrow 23. Preferably, gearwheels 26 and 28 are joined to the cylindrically shaped rollers 14 and 16, at their ends; however, gearwheels 26 and 28 may be joined at any other part of the surface or body of the cylindrical rollers 14 and 16, such as whereir spindles 30, and 32 are inoulded together with respective rollers 14 and 16. Thusly, wllers 14 and 16, have spindre 30, and spindle 32, respectively. The spindles 30, and 32, may he metallic rods rotatably fixed within the axial lengths of the cylindrical rollers 14, and 16. However, the spindles 30, and 32, may be joined together via moulding with respective rollers 14, and 16, and extending from the axes of the cylindrical rollers 14 and 16, to engagingly fix and journal into respective holes 32a for spindle 32 bored or recessed on the section of the chassis 12. Chassis 12 may be further divided into one or more portions so that there is provided chassis 12 and lower chassis 12a so as to enable access when the absorbent material 18 needs periodic replacing. It may thus be noteworthy to mention here that chassis 12a is indicated for the purpose of clearly elucidating and explaining relationships and positions of other fixed elements on the body of chassis 12 as a whole. That is, the chassis 12 is capable of being an integrally formed or moulded body which includes chassis 12a. Chassis 12 may further be integrally joined to include other sections or panels of the overall interior and exterior structure of the entire cleaning device 10, for example, chassis 12 may be integrally formed to feature one or more handle component supporting extcndahle structure or handle element 120; thc internal electrical elements and external user input control unit P; the dirty and clean liquid holding elements of the cleaning device 10, among others, whilst portion of chassis 12a features support for the cleaning device 10 on the surface 11.
Chassis 12 and chassis 12a may be positiond and or become referred to as, higher chassis 12, lower chassis 12, in a side by side upright or sideways arrangement, and so on. In some embodiments and variations of the invention below, chassis 12 may be linked to chassis 12a via movable jointing means. Chassis 12 and Chassis 12a may also be joined via fastening means, latching and or clamping means and so forth. Thereto, the spindles 30, and 32, are sufficiently journalled and rotatably engaged within bored or recessed spindle holes 32a and 30a which respectively correspond in alignment to receive spindles 30 and 32, onto chassis 12 and 12a respectively. Metal, nylon or other suitable washers means may be located between the spindle holes 32a and 30a and the spindle ends of the rollers 14 and 16, and likewise, bearings brushings means may bejoumalled between the spindle ends of the rollers 14, and 16, to the receiving corresponding spindle holes (32a and 30a) respectively which are bored or recessed into the either sections of the chassis 12 and 12a. The electric motor 22 is housed within a hermetically sealed casing (not shown) to avoid liquids and debris entering the motor components. Preferably, rollers 14, and 16, maybe equal ii size and or diameter; however, different sizcd rollers 14, and 16, in diameter or lengthjiiay be used.
Preferably, the liquid catchment means enclosure module J is a receptacle comprising at least one or more basin 20 which is integrally joined to one or more side-wails 36 and 34 and therefore capable of essentially holding a liquid or any other substance without spilling. The liquid catchment means enclosure module J may also have one or more access apertures 38 and 40 for allowing the passing absorbent material 18 to continuously enter and exit the liquid catchment means enclosure module J for regeneration.
The basin 20 is an integral constituent of the liquid catchment means enclosure module 3 and has volume generally encompasses from the area lying horizontally between rollers 14 and 16 and spreads to the surface of the basin 20 and side-walls 36 and 34 which essentially forms the internal liquid holding receptacle. On the opposite side of the internal liquid holding receptacle or basin 20 is the external section of the chassis 12a which is contiguously moulded in an uniform thickness from material such as hardened plastic or any other lightweight and robust material, so as to form and simultaneously act as a support for the interna(basin 20, and also as support forthe external section of the chassis 12a. Preferably, chassis 12 and 12a may be moulded as a contiguous part of the interior and exterior structure of the cleaning device; however, chassis 12 and 12a can be connected to the cleaning device 10 via pivoting or hinging means.
The external part of the section of the chassis 12a, has a substantially uniform thickness that is firm enough to act as support, and may be connected or joined together with section of the chassis 12 through any suitable connecting means (not shown), for example, via flexible or rigid hinges with quick-click locking and latching mechanisms. However, in some embodiments the chassis 12 and I 2a may be made of an integral moulded part which has apertures for allowing access for the entering and exiting passing absorbent material IS for regeneration. The basin 20 is a receptacle with one or more side open and is capable of holding any substance such as a liquid. The basin 20 extends in perpendicularly to form side-walls 34 and 36, essentially surrounding the basin 20. The side-waIls 34 and 36 have partial opening located away from the surface of the basin 20 to reveal corresponding apertures 38 and 40. The apertw-es 38 and 40 provide entry and exit access to the passing absorbent material 18 receiving regeneration within tlieliquid catchment means enclosure module.).
Preferably, the basin 20, area is constituted by a transverse central wall 44, which extends tangentially around the edges of the pressed rot lers 14 and 16, and along the imaginary line which joins the axes of the respective rollers 14 and 16, tojoin side-walls 34 and 36, so that rollers 14 and 16 are interposed between the central wall 44 thereby forming an impermeable wall which divides or partitions the basin 20, about centrally, to form basin portions A and B respectively. Thus, the central wall 44 contiguously extends from the surface area of the basin 20, to meet orjoin the surrounding side-walls 34 and 36, to form a pair of separate substantially symmetrical basin portions A and B, within the basin 20. Thus, in addition to the central wall 44, there may be provided a central wall blade 46, which is essentially a strip running tangentially or touchingly along the length of the cylindrical surface of the roller 14, so as to carry out the same duties as the central wall 44. There may also be provided a blade strip (not shown) located sandwiched longitudinally between the of the central wall 44, and touching with the cylindrical lengthwise surface of roller 16, so as to further seal-off or hinder stray or different liquids and or gases to remain withrn their respective basin portions A and B. The central wall blade 46. and the blade strip (not shown) can be made from a flexible resilient material such as moulded plastic silicon or rubber. The force of compression simultaneously exerted by rollers 14 and 16, on the absorbent material 18, fixed to support structure disc 19, causes the absorbent material 18, and disc 19, to become compressed and marginally expand thus extending in width and touching with surrounding side-walls 34 and 36, thereby forming a seal which then prevents liquids and or gases from jumping' from basin portions A to B or vice-versa. Similarly, where the absorbent material 18, and disc 19, does not reach or extend to the side-walls 34 and 36, there may be provided rigid spindles 30, and 32, with the rollers 14, and 16, covered in a resilient material that causes the resilient material to flex or become yieldable to compression due to the absorbent material IS and disc 19 being received in-between the surface of the rollers 14 and 16, and forming a seal between the absorbent material 18, the disc 19, and also along the surface of the meeting rollers 14, and 16, being urged together; wherein this action maintains or keeps any liquids and or gases hindered from permeating through and or passing in-between the cornpressional meeting surface points or tangents of the rollers 14, and 16. The compressing action of the r&llers stops any liquids and or gases gaining entry into either one ol basin portions A and or B, of the cleaning device 10 during use or storage. Thus, the central wall 44, central wall blade 46, the blade strip (not shown), and compressional force of the meeting rollers 14, and 16, (upon the absorbent material 18, and disc 19), all provide a joined contribution of unison effort in maintaining a sealed entity where liquids and gases cannot freely permeate through between basin portions A and or B, or leave either one or more types of basin portions A and 13, and between compartments, during operation when the absorbent material 18, :iii continuously enters and exits the liquid catchi-nent means enclosure module J, for regeneration, and also to keep such liquids and gases separate during the time of storage or transporting the cleaning device 10.
The surface area or volume of the basin 20 may further become partitioned or divided within respective basin portions A and B, by one or more inner-walls 42, 43,45 and 47. The inner-walls 42, 43, 45 and 47, contiguously extend or project from the surface of the basin 20, to join with surrounding side-walls 34 and 36, in the same manner as the central wall 44, extends from the basin 20, to join with the surrounding side-walls 34 and 36, and to remain at an even level or thereabouts with other similar walls (to be formed) within the basin 20, and leaving the sides opposite the surface of the basin 20, open. The creation of inner-walls 42, 43, 45 and 47, forms respective or individual compartments within basin portion A and B. That is, separate compartments F, C, H, in basin portion A, and separate compartments C, 0, E. in basin portion B, sharing support from section chassis 12a with which includes the liquid catchnienrnieans enclosure module J. Therefore, rcspective compartments F,C,H in basin portion A and respective compartments C,D,E in basin portion B, are created because of the introduction olthe dividing inner-walls 42,43,45 and 47, and including central waIl 44, which extends from the surface of basin 20 to joining with surrounding side-walls 34 and 36, which are also joined to the basin 20, and the side-walls 34 and 36, having at least one or more sides open, so that the volume between side-wall 36 and inner-wall 42 is in formed compartment H, and the volume between inner-wall 42 and inner-wall 43 is in formed compartment C, and the volume between inner-waIl 43 and central-waIl 44 is in formed compartment F within basin portion A of the liquid catchment means enclosure module J. And similarly, the volume between side-wall 34 and inner-wall 47 is in formed compartment C, and the volume between inner-wall 47 and inner-wall 45 is in formed compartment 0, and the volume between inner-wall 45 and central-wall 44 is in formed compartment E within basin portion B of the liquid catchment means enclosure module J. Thus, there may be more ways to ensure that liquids do ot gain entry during compression of the * absorbent material 18 by rollers 14 and 16,korn either one of the basin portions A and to basin portion 13 or vice-versa. Thus, more implementable ways in which to make certain that liquid is hindered from passing from one basin portion A and or B during the moment when portion of the absorbent material 18 is encountering compression force from rollers 14 and 16 is paramount and while the cleaning device 10 is being used in a either flat, sloppy or upside-down surface, One way is to seal the gap which would otherwise become apparent or exposed when the absorbent material 1$ is fully compressed, reaching the maximum volume of compacting thickness by the parallel surfaces of the rollers t4 and 16, and thence forming a gap (between the rollers 14 and 16) which thence allows liquids to freely flow thru and into the other side (in compartment E) of the already compressed portion of the absorbent material 18 meant to remain in a dry or semi-dry state, can be achieved by maximising the extent by which side-walls 34 and 36 come into near-contact or extend to nearly touching with moving members, and in particular the support structure that the absorbent material 18 is fixed to. or the disc 19, and also nearest or proximate to the edges of either one or both rollers 14 and 16. Thus. it may be crucial to raise or extend the side-walls 34 and 36 around where the edge of one or both rollersA4 and 16 are located, and specifically the side of the edge of roller 16 which is nearcst to the diametrical centre of disc 19, so that the portion of surrounding side-walls 34 and 36 is adjacently extended along and nearly touching with edge of roller 16, also nearly touching the edge of the absorbent material 18, and nearly touching the surface of the rotatable disc l9so as to remove any gaps that would otherwise cause liquids to pass through, thereby forming an untvan [Jbr1 in maintaining a sealed entity whereby liquids and gases cannot freely permeate through via gaps in-between basin portions A and or B, or leave and escape either one or more extensions of basin portions A and B, and in-between compartments F, and compartment E, or during operation of the cleaning devicelO in general when the absorbent material 18, continuously enters and exits the liquid catchment means enclosure module J, for regeneration, and also to keep such liquids and gases separate during the time of storage and or whilst transporting the cleaning device 10.
In another embodiment of the above sealing entity aspert, rollers 14 and 16 may have irregular * diametrical measurements along the length oJ their surfaces, so that as the absorbent material 18, attached to the support structure, (or any other type of support structure which may be flexible or rigid and that can be ring-shaped or belt shaped and having lesser compressional properties than the absorbent material 18 attached herein) disc 19 does not jeopardise or come-into-the-way of compression of the absorbent material 18 meeting rollers 14 and 16 by thence stopping the amount of compressing pressure exerted from the meeting rollers 14 and 16's parallel surfaces reaching to compress the softer absorbent material 18 to eject liquids within the porous body because ofthe much harder support structure. In order to correct this obstacle wherein surfaces of rollers 14 and 16 lie fiat on each other, the diametrical surfaces of rollers 14 and 16 may have to become (inwardly or outwardly) stepped, grooved and or gradually tapered so that thickness, width and rigidity of the disc 19 (or flexible or inflexible ring or belt support structure in another embodiment) does not come into the way of the meeting and compressing rollers 14 and 16, and such rigidity causing hindrance (to rollers 14 and 16) in exerting compression to the softer absorbent material 18 (that needs compressing) due to the harder rigidity properties of the di3c 19 (or flexible or inflexible ring or belt support structure in another embodiment) sucj that the absorbent material 18 becomes inadequately compressed. Thusly, correspondingly shapcd grooves, steps, cones, U, V or W shaped gorges, neck and or collars may havc to be made on one or more of the surfaces of the rollers 14 and 16 which correspondingly mate with same such grooves on the support structure or disel9, thereby providing the escape valley' from compressing the harder support structure, so that the exerting roller 14 and 16 force adequately reaches the sandwiched absorbent material 18 to eject liquids from within porous body. One of the advantages of the escape valley' is to provide continuous alignment for the absorbent material 18 attached to harder support structure or discl9 during continuous motions and -ft tensions, providing a valley for the harder support structure (or disc 19) to run within and crucially avoiding the compressional force of the rollers sandwiching the absorbent material 18. The escape valley' also provides an optimal play tolerance to the rigid part of the disc 19 (or other support structure such as a flexible or inflexible beit, or rigid ring in another embodiment). This mechanism causes the absorbent material IS to become fully exposed and adequately compressed by rollers 14 and 16, and the waste liquids ejected away from the porous body, whilst still maintaining fixed contact with the support structure such as the disc 19 (or other support structure such as a flexible or inflexible belt rigid, ring in another enibodinint) which is now hidden' in corresponding grooves or gaps arranged between the surfaces of the rollers 14 and 16 and the support structure such as a belt, ring or disc. In the present example, compression forces of the rollers 14 and 16 sandwich the softer absorbent material 18 and harder support structure disc 19; and the properties of the harder support structure also exerting pressure from the rollers 14 and 16 to the absorbent material 18.Thus crucially, liquids are denied as much as possible permeation, infiltration and or sipping across or in-between sections of the basin 20,so asto remove any gaps around mechanisms of the meeting rollers 14 and 16, the absorbent material 18 and disc 19, so that waste liquids do not pass through, thereby forming an unison effort in maintaining a sealed entity whereby liquids and gases cannot freely permeate through via gaps in-between basin portions A and or B, or leave and escape either one or more extensions of basin portions A and B, and in-between compartments F, and compartment E, or during operation of the cleaning device 10 in general when the absorbent material 18, continuously enters and exits the liquid catchment means enclosure module J, for regeneration, and also to keep such liquids and gases separate during the time of storage and o' whilst transporting the cleaning device.
Still, a ftirther drive to curb liquids within cipartments between basin portions A and or B, from leaving or crossing over to different compartments during use of the cleaning device 10 while the absorbent material IS continuously travels (at either direction) through within the liquid catchment means enclosure module J, the inner-walls 42, 43, 45 and 47, and side-walls 34 and 36 may have to become adapted or moulded into a positioned which favours containing the liquids therein. Thus, it may be preferable to have the inner-walls 42,43,45 and 47 positioned in a manner such that liquids at the basins 20, are constantly steered or channelled towards a strategically preferred location e.g., towards the drainage ports, during when the cleaning devicelo is operated on a horizontal plane such as a floor, and also when operating the cleaning device lOon a vertical plane such as a wall. Thusly, it is preferred that the inner-walls 42, 43, 45 and 47 be positioned (perpendicular to the basin 20 as shown in FIG 1), and sloping or slanted slightly at an angle around 60°; so that side-wall 36, inner-walls 42 and 43, in basin portion A slants 600 towards the central wall 44, and similarly, for side-wall 34, inner-walls 45 and 47 in basin portion B slant 60° towards central wall 44. Side-walls 34 and 36, and inner-walls 42, 43, 45 and 47 may be nioulded to be flexible around their apexes and gradually become rigid towards the intersection where they meet with the basin 20. This allows for some receptiveness and or submissiveness of the apexes becoming experienced by the absorbent material 18, providing an additional flexible liquid retentive capability within the liquid catchment means enclosure nioduJe J and crucially during the period when the cleaning device 10 is used on horizontal, vertical and or upside-down plane or surface such as a wall and ceiling, and including when the cleaning device 10 is in storage or being transported.
Once the absorbent material 18 has encountered adequate compression from rollers 14 and 16, and left in a clean arid semidry or dry state, the body of the absorbent material 18 travels within compartments E, D, and C in the same manner as when travelling within compartments H, G and F, in accordance to directional arrow 54, before recurring the cycle of continuously entering liquid catchment means enclosure module J, for regeneration via aperture 38, and exiting via aperture 40.
With reference to FIG 1, during operation, the travelling absorbent material 18 encounters continuous entry and exiting the liquid catchment means enclosure niodule J, via aperture 38, (which has a resiliently flexible receptive aperture lip 39), s shown by directional arrow 54 and exiting the liquid catchrnent means enclosure module,J thru aperture 40, (which has a resiliently flexible receptive aperture lip 41), as shown by the direction of arrow 55. It may therefore be desirable to eliminate as much as possible the amount of friction or drag created or produced during the exertion of the constantly opposing forces between the passing absorbent material 18, the disc 19 and against the sections of the chassis 12 and 12a. Thus, by moulding the apex edges of the aperture lip 39, aperture lip 41, inner-walls 42, 43, 45 and 47, into tubular, rounded, domical or curved shape may he necessary so that the passing absorbent material 18, travels in and out and in-between the roller 14 and roller 16 within the liquid catchment means enclosure module J in a smooth and continuous flow.
Additionally, apex edges of inner-walls 42, 43, 45 and 47, may have free-rolling components (not shown) attached in the place of the tubular, rounded, domical or curved apexes of the inner-walls 42, 43,45,47 and aperture lips 39 and 41, that are in constant contact with the passing absorbent material 18. Similarly, a series of one or more rotatable elements 48,49,50,51, 52 and 53 can be correspondingly arranged on one section of the chassis 12, so as to align with the apexes of aperture lips 39 and 41, inner-walls 42,43,45 and 47,j.n order to reduce friction and drag between the passing absorbent material 18 and disc 19, and against the locked-together sections of the chassis 12 and 12a, which sandwich the passing absorbent material 18 during use of the cleaning device 10. Essentially, the compressional force between the sections of the chassis 12 onto the section of the chassis 12a and sandwiching the resilient absorbent material 18 and disc 19, in-between, causes some portions of the body of the resilient absorbent material 18 to become compliant or temporarily altered once compressed along the lines of alignment between the apexes of the aperture lips 39 and 41, the apexes of the inner-walls 42, 43,45,47, and the oppositely aligned rotatable elements 48,49,50,51,52,53, and against the rollers 14, and 16 respectively. Preferably, the force of pressure applied by the opposing sections of the chassis 12 and 12a is sufficiently maintained by a locking mechanism (not shown) so that the absorbent material 18 is able to freely or fiowingly enter and exit the liquid catchment means enclosure module J for regeneration during use of the cleaning device 10. Crucially, this arrangement evenly covers the remaining open side (of the now partitioned basin portions A and 8,) with the absorbent material 18 thereby forming separate and closed volume compartments C,D,E,F,G and H therein. Again the force of compression simultaneously exerted by the meeting of the aligned apexes of the inner-walls 42,43,45 and 47, the apexes of aperture lips 39 and 41, and oppositely aligned rotatable elements 48,49,SO,51,52 and 53 and also from the rollers 14, and 16, causes the resilient and absorbent body oltbe passing absorbent material 18, to become marginally expanded thus extending in width and touching with surrounding side-walls 34 and 36, thereby covering compartments F, C, H and E, C, 9, and forming a seal' therein. This sealing action caused by the passing resilient absorbent material 18 being pressed by the pressure from the oppositely located rotatable elements 48,49,50,51,52 and 53 (fixed on chassis section 12), onto apexes of the inner-walls 42,43, 45,47, the apexes of aperture lips 39 and 41 that form compartments F, C, Hand K, C, D, prevents liquids, liquid-dirt mixture or waste liquid 66, gases and various other substances within the compartments F, C, 11 and K, C. 9, (and such liquids and gases within the porous body of the absorbent material IS), from escaping or jumping' from one compartment to another or leaving the interior of the aperture lips 39 and 41 as the passing absorbent material 18 travels (and at any direction e.g., from right to left or vice versa) via the liquid catchment means enclosure module J for regeneration during use of the cleaning device 10 because the force of pressure between rotatable elements 48,49,50,51,52,53 and apexes of inner-walls 42,43, 45,47, and apexes of aperture lips 39 and 41 (pressing upon flexible disc 19) divides' portions of the resilient permeable body of the absorbent material 18 within said respective compartments F, C, II and E, C, 9 due to the compressing pressure along the said apexes forming sealed closed volumes therein. Preferably, aperture lips 39 and 41 may be made from a resilient lining or yieLdable material such are rubber moulding around the entrances of aperture 38 and aperture 40, so that as the absorbent material 18 travels according to direction arrow 54, aperture lip 39 is prevented from forcing out or expelling waste liquid 66 and debris from the face 17 and body of the absorbent material 18 before the passing absorbent material 18 enters into compartments 1-I, C, and F (in basin portion A) of the liquid catchment means enclosure module J via aperture 38 for regeneration. During the period when the absorbent material 18 is travelling via liquid catchment means enclosure module J in the direction opposite that shown by arrow 54, aperture lip 41 responds in the same submissive manner as aperture lip 39 does when the absorbent material 18 travels via the liquid catchment means enclosure module J in the direction shown by arrow 54. Therefore, waste liquid 66 and debris is prevented from being prematurely expelled from the body of the absorbent material 18 by either aperture lip 39 and 31, prior to the absorbent material 18 entering into compartments I-I. C. F and or C, 9, E regardless to the direction travelled via the liquid catchment means enclosure module.1 by absorbent material 18.
Thus, with reference to FIG 1, as the body of the passing absorbent material is enters the liquid catchment means enclosure module J for regeneration, according to directional arrow 54, via aperture lips 39, there is provided a rotating brush element 56 with bristles in nominal contact with the passing absorbent material i8,within compartment I-I of the liquid catchment means enclosure module.1, so that the bristles of the rotating brush element 56 comes into contact with the portion of the face 17 and interfere with the absorbent material 18 exposed in compartment I-I, thereby flicking loose contaminants waste liquid and dirt debris 58 away from face 17 of the absorbent material 18; thence subsequently (and as following the direction according to the directional arrow 54), the portion of the absorbent material 18 previously brushed-off in compartment H, follows-on to proceed into compartment 6 after being compressed temporarily by apex of inner-wall 42. II should be noted that there may be provided one or more nozzles or perforations on one or more liquid applicators 62,60 so that perforations 13 eject or discharge liquid or gas from liquid applicator 62 in basin portion B, whilst periorations 15 eject liqLlid or gas ftonrliquid applicator 60 in basin portion A. The term liquid applicator may also represent the purpose of the said liquid and gas ejecting nozzles and perforations therein. Once portion of the absorbent material 18 is within compartment C encounters liquid 64 being ejected, in the direction of arrow 63 from discharge nonle of liquid applicator 60 fixed within compartment G onto face 17. Liquid applicator 60 is fixed nearest and facing the exposed portion of the body of the passing absorbent material 18, within compartment 6, so that as the absorbent material 18 travels or passes (according to directional arrow 54) liquid applicator 60 squirts, sprays or discharges liquid 64 onto body portion and face 17 of the ofthe absorbent material 18 exposed within compartment 6 and in the direction of arrow 63. Thus subsequently, (as the absorbent material 18 follows the direction according to the directional arrow 54), the portion of the absorbent material 18 previously sprayed with liquid 64 in compartment C, progresses into compartment F after being briefly compressed by apex of inner-wall 43 which acts also as an inhibitor and remover of excess mixture olwaste liquid 66 and liquid 64 collected and or absorbed from compartment C by portion of the passing absorbeni material 18. Once in compartment F, the travelling absorbent material IS encounters the gradual narrowing of the circmferential constriction due to the tangential touching surfaces of the lengths of (lie rollers 14, and 16 which constantly rotate into each other (according to rotational direction arrow 27 and 29) thus pulling or forcing the sandwiched absorbent material 18 in-between the surface-lengths of the rollers 14, and 16. The action of the compressing force exerted by the meeting surfaces of the rollers 14, and 16 causes the portion ofthe absorbent material 18 which lies along the tangential lengths of the surfaces of the rollers 14, and 16 to become compressed and the absorbent porous compliant body altered in shape to a substantial degree, which thence causes the surfaces of the meeting rollers 14, and 16 to compress and eject away from the porous absorbent body, all contaminants, liquid and debris or waste liquid 66 held within the absorbent body 18, thereby leaving the expelled waste liquid 66 into compartment F, as the compressed portion of the absorbent material 18, (which is now sandwiched between the rollers 14, and 16) travels towards compartment E. This leaves the compressed altered portion of the porous absorbent material 18, which is now leaving the line-of-compression exerted by rollers 14. and 16 in a reconstituted form and becomes uncompressed and in a dry or semi-dry state and now located onto the side of cornpai-rment E, of the liquid eatchment mens enclosure module J, and according to directional arrow 54. Thus, the portion ol'the body ofthe absorbent material 18 which was previously soaked wet when within compartment F, is now in compartment E in basin portion B, and according to directional arrow 54, and the portion of the absorbent material 18 now being free from any liquids and debris (or waste liquid 66) after encountering the force exerted by the meeting surfaces of the rollers 14 and 16, (and rotating brush 56 in compartment I-i), thereby continuously leaving all following portions ofthe rest of the body of the absorbent material 18 in a clean dry and or semi-dry state whilst continuously traveling according to directional arrow 54. Next, the travelling clean semidry or dry portion of the absorbent material 48 enters compartment E, and leaves whilst being moderately compressed and the compliant body temporarily altered by apex of inner-waIf 45, before entering compartment U, wherein portion leaves whilst being moderately compressed by apex of inner-wall 47, and before portion entering compartment C, wherein may encounter rotating brush 57 before portion exiting the entire liquid catchment means enclosure module J, via the aperture 49. During the period when travelling absorbent material 18 enters basin portion B, (according to directional arrow 54) and toward aperture 40 via compartments E, U and C, Pquid applicator 62, is disabled so as not to soak the already dry or semidry absorbent merial 18 which crucially at this stage needs to remain dry or semidry and to exit the liquid catchment nieans enclosure module J. in this condition. In some embodiments, the absorbent material iS may he treated or made to interact with certain chemicals or gases introduced within respective compartments by discharging elements (not shown), during the period the absorbent material 18 travels through the liquid catchment means enclosure module J (in direction of arrow 54) and or in a dry or semidry state after encountering rollers 14 and 16 and in basin portion B. For example, a sanitizing gas such as hydrogen peroxide, silver nitrate, NA V-C02, a drying agent, or any other chemical or gas may be constantly pumped and remained in pressure within respective compartment therein order to interact with the face 17 and or porous body of the passing portions of the absorbent material 18. In certain embodiments, apexes of the inner-walls 42,43, 45,47, may be hollow longitudinal tubes having the clean fluid delivery conduit 61 and 65 fixed through surrounding side-walls 34 and 36 via bored holes (not shown) aiid to one or more axes of the apexes of the inner-walls 42,43, 45,47 which have their surfaces coming into contact with the passing absorbent materia? 18. and said apexes having their surfaces perforated so that as the passing absorbent material 18 makes contact with id apexes, liquid (64) is expelled from said hollow tubular apexes and via said perforations and onto the face 17 of the passing absorbent material 18 so that the distance or gap (such as that shown in FIG 1) between the liquid applicators 60 and face 17 of the body of the absorbent material 18 is minimised and or absent. Preferably, fluid 64 may be clean fluid such as water; however, fluid 64 can be any other type of fluid. An advantage of this aspect may help reduce the tooling expenditures, amount of different parts for assembly and to essentially soak the passing absorbent material more sufficiently or deeper. In such an embodiment the apexes of the inner-walls 42, 43, 45, 47, may carry out the tasks of respective liquid applicators 60 and 62, so that it may be possible to have said perforated apexes, and respective liquid applicators 60 and 62 working side by side in compartments and even dispensing different types of liquids for example, within respective compartment G, there may be provided perforated apex of inner wall 42 working along liquid app] icator 60 and dispensing different liquids such as a disinfectant from the perforated apex of inner wall 42 and a clean fluid such as water from the liquid applicators 60, or vice versa. In certain embodiments, surfaces of apexes of the inner-walls 42, 43, 45, 47 (where the absorbent material 18, presses on whilst moving via the liquid catchment means enclosure module J) may be hollow and have perforations wherein suctioning force is fluidly introduced from suction means (not shown) and via holes on suid apexes (not shown) so that n-thture of contaminants collected from surface 11, waste liquid 66 and debris 5$ may be dislodged from the liKe 17 and body of the absorbent material 18, thru the force of suction there through, leaving said absorbent material 18 in a clean dry or semidry condition. In other embodiments rotatable elements (not shown) may be rotatably fixed on the surfaces of apexes of the inner-walls 42, 43, 45, 47 and aperture lip 39 and 41 wherein the passing lace 17 of the absorbent material 18 comes into contact with said apexes thereby reducing friction between said apexes and the passing absorbent material IS saving energy and the load upon the motor. Thus, as the absorbent material 18 travels through the liquid eatchment means enclosure module S. for regeneration, and at direction according to arrow 54, apexes of the inner-wails 42, 43, and 47 collide with the resilient body of the passing absorbent material 18 causing a furrowing-action on the face 17 and body of the passing absorbent material 18, altering and temporarily compressing the shape at the point where the rigid surfaces of the of the apexes of the inner-walls 42,43,45 and 47 meet the face 17 of passing absorbent material 18. This action crucially divides the resilient body ol the absorbent material 18 into successive sections according to the compartments H, C and F formed between th side-wall 36 and central wall 44 by the rgid structure of apexes of the inner-waIls 42, 43. and aperture lip 39, so that overhanging portions of face 17 are exposed successively along and within compartments H, C and F of basin portion A. Once overhanging portions of the body of the absorbent material 18 passes through rollers 14 and 16, according to direction arrow 54, and are within basin portion B, face 17 of the absorbent material ISis compressed in the same manner by rigid apexes of inner walls 45,47 and aperture lip 40, and face 17 becoming overhang and exposed within separate compartments E, U and C, before exiting the liquid catchment means enclosure module J via aperture 40. One advantage of the furrowing-action provided by the rigid apexes onto passing absorbent material 18 is that loosed dirt and debris 58 and including contaminants of waste liquid 66 are easily agitated, scraped and removed from the soaked body of the absorbent material 18. Another advantage of the furrowing-action provided by said apexes is that speci lie and or different chemical elements that maybe in liquid or gaseous form can be introduced to the exposed overhanging sections of the bony of the absorbent material 18 during the moment the passing body of the absorhci material 18 passes over any separating walls of compartments H, C, F, E, I) and C and exposes portions of face 17 in said compartments. Thus, as the absorbent material 18, enters into the liquid catchment means enclosure module.1, in direction arrow 54, and through aperture 38, and received by submissive aperture lip 39, wherein then encounters rigid apexes of the inner-walls 42, 43, 45, 47, so that the resilient body of the absorbent material 18 moulds shape according to the restrictive pattern caused by the rigid surfaces of the apexes of the inner-waIls 42, 43, 45, 47 and causing lace 17 of the resilient absorbent material 18 to overhang and facing into respective volumes of compartments H, C, F, E, D and C while travelling along the said apexes thereby essentially and sufficiently covering so as to firmly enclose receptacles
F
of respective compartments H, C, F, E, U and C therein forming a closed volume within, so that it may be possible to administer one or more types of liquid or gaseous chemical elements within an individual compartment so as to treat or interact with the passing portions of face 17 of' the absorbent material 18 exposed within said individual compartments, and said chemical elements being delivered into the respective said compartments via conduits (not shown). Holes (not shown) may be bored or moulded on the surface of the side-walls 34 and 36 and connected to said conduits delivering said chemical elements. Said chemicats elements may be sanitizing agents that may be in liquid or gaseous form, or a combiiwtion ol' both. For eample, the introduction of certain sanitizing agent like an antiseptic may be introduced in one coinpartnient and the neighbouring compartment administering a different sanitizing gas or liquid such as silver nitrate, hydrogen peroxide, NAV-C02 onto the exposed portion or face 17 of the passing absorbent material 18 travelling through the liquid catchment means enclosure module J, for regeneration. Since such and other sanitizing chemical elements may be expensive to purchase and may be safely used more than just once, depending on the degree of contaminant concentration within certain compartment, it may be necessary to recirculated or recycled such chemical elements so that dislodged dirt and debris collected can be removed by conventional filters or other means, so that the retrieved chemical element may be recirculated or reused back into tile required compartment for interaction with the passing absorbent material 18. in some embodiments, it may be possible to treat or interact said sanitizing chemical elements in gaseous or semi gaseous form with the absorbent material 1$ afler compression (by rollers 44 and 16) in order to sanitize the absorbent material 18 before it leaves the liquid catchment means enclosure module Jvia aperture 40 to resume contact with the cleaning surthce 11. In certain other embodiments, it may be possible to have irradiative elements or amps (not shown) positioned within said companments or along the lengths of said apexes so as to sanitize the passing absorbent material 18 in usc, wherein said irradiative elements may be ultra violet light emitters. Microbe destroying metals such as silver may be lined on surfaces of said apexes or any other surfaces within the liquid eatchment means enclosure module J, or relative conduits so that said emitted ultra violet light may be reflected upon and within gaseous or liquid medium and destroy the germs therein. In other embodiments, it may be possible to have microbial screening elements (not shown) positioned within said compartments, along the lengths of said apexes or in any other convenient sample collecting or sample screening location. The. absorbent material 18 then leaves liquid catchment means enclosure module J, after regeneration via aperture 40.
Meanwhile, liquid 64 ejected from liquid applicator 60 is delivered from one or more clean fluid storage container or clean fluid tank NI, by conduit 86 which further branches and is fluidly connected to one or more conduit 61 and conduit 65 which terminate inside liquid catchnient means enclosure module J. A pumping means W d)ivers clean fluid (from the clean fluid tank M) in the direction of arrow 73 through conduit 86 which may branch into (one or more) conduit 61 and conduit respectively delivering clean fluid in the direction of arrow 63 and arrow 67 into separate liquid applicator 60 in compartment 6, and liquid applicator 62 in compartment U wherein conduit 61 and conduit 65 terminate. While liquid applicator 60 is permitted to squirt liquid 64 in the direction or arrow 63 and onto the passing face 17 of the absorbent material 18 within compartment C of the basin portion A of the liquid catchment means enclosure module J, symmetrically opposed compartment D of basin portion B is prevented from ejecting any liquid &om liquid applicator 62 and in the direction of arrow 67 onto the portion face 17 of the passing absorbent material 18 travelling according to direction of arrow 54 through the liquid catchment means enclosure module J, because the passing absorbent material 18 is needed to remain in a dry or semidry state after encountering rollers 14 and 16, and before exiting the liquid catchment means enclosure module J via aperture 40. Thus, according to FIG 1-4, a manually or automatically controlled fluid or gas diversion means 92 may be located at thejunction or intersection wherein the conduit 61, conduit 65 and conduit 86 meet, so that during operation when the absorbent material 18 is travelhig at the direction according to arrow 54, the fluid or gas diversion means 92 rermits liquid 64 in compartment C of basin portion A to become ejected according to alTow 63 from conduit 61 via liquid applicator 60 onto the face 17 of portion of the absorbent material 18; whilst symmetrically opposed liquid applicator 62 in compartment D of basin portion B is prevented by Iluid or gas diversion means 92 from ejecting any liquid (such as liquid 64) in the direction of arrow 67 onto face 17 of portion of the passing absorbent material 18. On the other hand, when the absorbent material 18 is travelling through the liquid catchment means enclosure module.J, in the direction opposite to that of arrow 54, liquid applicator 60 in compartment C of basin portion A is prevented by fluid or gas diversion means 92 from ejecting liquid 64 delivered by conduit 61 according to arrow 63 onto the face 17 of the passing absorbent material 18.
Additionally, liquid applicator 62 in compartment fl of basin portion B is permitted by fluid or gas diversion means 92 to eject liquid delivered via conduit 65 according to direction of arrow 67, onto the face of the passing absorbent material 18 when travelling in the direction opposite to that of arrow 54. The purpose of the above mechanism is to ensure that the absorbent material 18 always leaves either one of aperture 38 or aperture 40 of the liquid catchitent means enclosure module.1, in a clean dry or semidry state regardless of the direction the absorbent material 18 travels via the liquid catchrnent means enclosure module J, and before recommencing contact with the surface 11. The fluid or gas diversion means 92 may also be used to direct other liquids and or gasses to other sectors of the cleaning device, e.g to one or more surface liquid applicators. Specifically, once portion of the face 17 of the absorbent material 18 is adequately soaked with liquid from clean fluid tank M, thru either one of liquid applicator 60 or liquid applicator 62, depending on the direction travelled by the absorbent material 18 thru the liquid catchment means enclosure module J, so that once the rollers 14 and 16 compress the soaked body of the absorbent material 18, mixture of waste liquid 66, liquid 64 and contaminants solution collected from surface 11 is expelled from the porous body of the absorbent material IS which thence continues to travel through the liquid eatchment means enclosure module 3 whilst remaining in a dry or semidry condition, before exiting the liquid catchment means enclosure module J to resume contact with surface 11. There may be provided a tank-empty sensor (not shown) housed therein clean fluid tank M and be configured to communicate a tank-empty signal to the main control unit N when clean fluid tank ri is empty. Once clean fluid tank NI is empty, a user may then manually refill the clean fluid tank M by unlatching and removing clean fluid tank Ni which is configured to be easily removable from the chassis 12 or 12a by uncapping the removable tank cap 88 which includes conduk8ó fixed there-through, or the user may refill the clean fluid tank Ni while fixed on chassis 12 via access from the sealable and removable tank cap 88.
However, in certain embodiments, the cleaning device JO may be configured to have one or more permanently connected or removable interface element 83 engagingly connected to interface port 84 (according to direction of arrow 85) which then connects conduit 86 fluidly interposed and connected via conduit 86a to an external clean fluid source via conduit 87, so as to deliver clean fluid to liquid applicator 60 in compartment C of basin portion A and liquid applicator 62 in compartment D of basin portion B from a clean fluid source located away from the chassis 12 and 12a of the cleaning device 10. Preferably, there may be provided within the interface port 84 one or more valve mechanism means (not shown) that remains shut until pressed open once the interface port 84 correspondingly mates and engages with interface element 83 according to direction of arrow 85, so that an opening is created when a pushing element (not shown) penetrates either one of said interfaces to fluidly unite conduit 86a and conduit 87 thereby allowing clean fluid to pass through into the cleaning device 10, from an external clean fluid source or reservoir (not shown) located away from the cleaning device 10. [he conduit 86 may b&ome interposed or connected to one or more conduits for the purpose oI distributing liquid 64 to other components of the cleaning device 10, e.g to surface-liquid applicators 136 and 138. In certain embodiments, the clean fluid may be recirculated or recycled and the dislodged dirt and debris collected removed by conventional filters or other means, so that the retrieved grey clean fluid saving soap (or other sanitizing agent such as an antiseptic liquid or gas) and clean fluid (such as water) consumption. Once in compartment F, portion of the rest of the body of the absorbent material 18 previously being sprayed with liquid 64, in compartment C, is now within compartment F. Preferably, liquid 64 is a clean fluid free from contaminants and or pollutants. Thusly, as the absorbent material 18 continuously travels via liquid catchment means enclosure module.1, the force compression against the passing absorbent material 18 may be increased or decreased by increasing and decreasing the distance between apexes of inner-walls 42, 43,45 and 47, aligned to opposing rotatable elements 49,50,51 and 52. When the distance between the apexes of inner-walls 42, 43,45 and 47 and rotatable elements 49,50,51 and 52 is reduced, additional force is exerted on the body of the sandwiched and passing absorbent material 18, thereby removing or expelling extra liquid and debris away frOm the porous body. When the distance between the apexes of inner-walls 42, 43, 45 and 47 and rotatable elements 49,50,51 and 52 is increased, less force is exerted on the body of the sandwiched and passing absorbent material 18. An advantage of this aspect is that more liquids or gases (such as sanitizing hydrogen peroxide, silver nitrate, NAV-C02, chlorine, steam, hydrides) can be introduced within respective compartments within basin portion A and Band forced to remain therein whilst portions of the body the absorbent material 18 continues to pass by. Also, it may be possible to have separate successive cleaning, rinsing and sanitizing stages and processes applied respectively on portions of the absorbent material 18 whilst passing via compartments H, C, F, E, fl and C, before leaving the liquid catchment means enclosure 1 TD a'.'.
moduie 3 via aperture 40, according to directional arrow 54.
Rotating brushes 56 and 57 serve the same purpose regardless of the direction the absorbent material 18 passes by. Rotating brushes 56 and 57 are joined to longitudinal cods or spindles 31 and 33 which are Further rotatably joined in holes (not shown) bored in opposite inner walls of compartment H and compartment C respectively and in such a way that doesn't hinder or greatly reduce the pace of their sufliciein rotation. Rotating brushes 56 is joined to spindle 31. Multitudes of bristles in clumps that form rotating brushes 56 and 57 are fixed to spindles 31 and 33 respectively. Therefore. plurality of bristles radially extend from spindle 31 so as to make contact and resiliently bend as each bristle makes contact with the entire width of face 17 of the passing absorbent material 1$ in compartment Ii. SiniilaHy, rotating brushes 57 is joined to spindle 33 from wherein plurality of bristles radially extend from spindle 33 so as to make contact and resiliently bend as each bristle makes contact with the entire width of face 17 of the passing absorbent material 18 in compartment C. Preferably, rotating brushes 56 and 57 may rotate at any direction so long as they rotate at a pace that adequately removes contaminants dirt and debris 58 and 57 from absorbent material IS travelling via the liquid catchment means enclosure module J in direction of arrow 54. However, is some embodiments, rotating brushes 56 and 57 may rotate in an opposite direction to that which the passing absorbent material 18 may be passing, so that bristles of rotating brushes 56 and 57 produce a firmer shearing force as they rotate touching with body portion of passing absorbent material IS. The said shearing force produced by the multitude of bristles in rotating brushes 56 and 57 breaks adhesion bonds between lbce 17 of the absorbent material 18 and contaminants dirt and debris 58 and 57. One or more flicking means 69 and 71 dislodge conLa iinant dirt and debris 58 and 57 adhered to the rotating bristles oF brushes 56 and 57. Suitable means to rotate the brushes 56 and 57 may be carried out via chain elements connected to sprockets fixed on suitable locations on spindles 31 and 33. Other means to rotate spindles 31 and 33 may be through; using pulleys connected to said spindles and said pulleys connected suitably to rotating element e.g. spindle 32; or by drive motors connected to drive spindles 31 and 33; or by combination of mechanical drive transmission elements connected to one or more drive motor so as to continuously rotate spindle 31 and 33; or by using the free motion borrowed and or harnessed from the freely available velocity of the passing absorbent material 18 thereby rotating one or more gearwheels which may have increased or decreased gearwheel ratios and or gearwheel sizes, and are interconnected and or mated to gearwheels fixed to spindles 31 and 33 so that brushes 56 and 57 rotate faster or slower than the pace of the passing absorbent material 18, or so that the brushes 56 and 57 rotate in the opposite direction to that of the passing absorbent material 18 which they derive their rotating energy from, and without comprnmising the pace, drive motor energy and efficiency of the ovcrall mechanisms working to continuously move the absorbent material 18 in.
through and out of the liquid caichment means enclosure module.J. In certain embodiments, scraping elements and or brushes such as the rotating brushes 56 and 57 maybe situated or positioned outside or away from the liquid eatchment means enclosure module J and in contact with the passing absorbent material 18 so that dirt and debris nay be removed from (he body of the absorbent material 18 before entering liquid catchrnent means enclosure module 3 for regeneration. That is, a scraping means or brush may be positioned adacent to the mouth or aperture 38 so that dirt and debris is removed from the absorbent material 18 (travelling in direction of arrow 54), before entering the liquid catchment means enclosure module J. The same arrangement maybe repeated on the opposite mirroring side, so that the absorbent material 18 is treated in the same way (before entering the liquid catchi-nent means enclosure module 3 for regeneration) when travelling in the direction opposite that of arrow 54.
In other embodiments, it may be possible to have rumbles formed on the surfaces of revolving elements (not shown) within certain compartment(s), for example within compartment C. so that the body of the passing absorbent material 18 may be shaken by the rumbles to produce vibrations on the body of the absorbent material 18 whilst simultaneously being soaked and rinsed with liquid 64, causing the degree or level of contaminant particulate dirt and debris 58 removal to be abundantly increased and said contaminant contents dislodged rapidly from the shaking-soaked porous body and lace 17 of the passing absorbent material 18. Revolving elements (not shown) may work in similar or equivalent ways to rotating brush 56 or 57, thus, revolving elements (not shown) may be in the form of a drum or cylinder having an irregular surface which is arranged to remain in contact with the overhang face 17 and body portion of the passing absorbent material 1$, and said drum attached to a spindle so as to axially rotate in the same manner as that of rotating brush 56 or 57 does within their compartments. Orbital revolving means such as being connected to a cam arrangement may be used to shake the absorbent material 18 whilst liquid 64 is applied on lice 17 of said absorbent material 18.
Such revolving elements (not shown) may be free-running and rotated because of being in contact with the velocity of the passing absorbent material 18. Other vibrating elements that may be implemented to simultaneously agitate and increase removal of particulate dirt and debris contents from the soaked passing absorbent material 18 is by using ultra (sonic) sound emitters that may be located within compai-tmenls e.g. where liquId 64 is expelled. Other vibrating elements may be in contact with the passing absorbent material 18 travelling thru the liquid catchment means enclosure module J for regeneration.
In yet another embodiment of the above aspect, it may be possible to have the distance between rollers 14 and 16 alterable in the same manner as described above. Therefore, another advantage of this aspect is that energy loads and the power to rotate the rollers 14 and 16 can be reduced thereby saving the drive motor 22 during operation or cleaning cycles that do not require extra force or energy to remove contaminants from the porous body of the absorbent material 18. For example. when cleaning a surface with a concentrated contaminant such as soil or ink, this may require extra force and rinsing Liquid to expel the contaminants or waste liquid 66 from the body of the absorbent material 18 travelling within the liquid catchment means enclosure module S for regeneration. On the other hand, when cleaning a surface which is not too dirty using the cleaning device herein, clean liquid 64 may he recirculated and lesser compression force may he exerted on the rollers 14 and 16, thereby requiring lesser energy to drive the drive motor 22. In such ajuncture, transient switches (not shown) can automatically switch energy consmption without interruption to the cleaning device 10 Iron) an electrical AC mains outlet, to a portable power source within the cleaning device. This aspect may save money on electrical utility bills as well as save carbonic emissions at the electricity producing powerhouse, thereby constantly thriving to maintain a low environmental impact without compromising efficiency of the cleaning device. The mechanism to increase or decrease the pressure exerted between the rollers 14 and 16 may be controlled via an automatic switch or manually via a lever that can be operated by hand or leg lever (not shown) by a user of the cleaning device.
Pretèrably, the leveraging means for increasing or decreasing compression between rollers 14 and 16 can be automatically linked to a sensor means (not shown) which senses conditions such as the content of particulate concentration suspended within the waste liquid 66 so as to automatically activate the reduction or increase of the gap between surfaces of rollers 14 and 16 and gap between aligned apexes of inner-walls 42, 43, 45, 4? and rotatable elements 49,50,51,52. In such an embodiment where extra force or pressure between inner-walls 42, 43.45 and 47 and rotatable elements 49,50,51 and 52 can be added or reduced upo.a the sandwiched and passing absorbent material 18, by automatic actuatton means coMrolled by a particulate concentration content sensing means (not shown) which measures particulate concentration suspended in waste liquid 66. The particulatc concentration content sensing means (not shown) may be configured to communicate information about the amount of particulate concentration content suspended within the ejected waste liquid 66 to the main control unit N, so as to activate tasks such as; the increase or decrease ofthe pace of the passing absorbent material 18 by increasing or decreasing the amount of electrical energy delivered to run drive motor 22 which then drives rollers 14 and 16; increase or decrease the pace of agitation brush 56; or to actuate the increase or decrease of bursts of clean fluid such as liquid 64 in one or more compartments within the liquid catchment means enclosure module J; and to also balance the increase or decrease between waste liquid 66 and liquid 64 by controlling the evacuation means which remove accumulating and ensuing spent mixture of liquid 64 and contaminants solution from the absorbent material 18 spread within compartments F, C and 11 in basin portion A, thereby preventing welling, flooding or blockage therein. However, the evacuation means for waste liquid 66 and din debris 58 may come from constantly running fan or suctioning means 82 producing a negative pressure of vacuuming suction fore 82a which draws waste liquids and gases through drainage ports 68,68a.70.70a.72.72a,74,74a,76,76a.78,78a. in the direction of arrows Q, R, S, 1. U, V,thereby suctioning loose particles and debris 58 and waste liquid 66 away from the liquid catchment means enclosure module.1 and depositing then-i to waste tank K fluidly connected to the liquid catchment means enclosure module J via conduit element 80. Additionally compression levels between rotatable elements (not shown) on apexes of inner-walls 42, 43, 45. 47 and rotatable elements 49,50,51 and 52, may be controlled by the particulate concentration content sensing means (not shown). There are other sensing needs such as the liquid levels within different compartments that may also be measured by the particulate concentration content sensing means (not shown) or by other sensing means that can communicate such signals to and from the main control unit N. It may also be possible for one or more of the above tasks to be carried out simultaneously within a single compartment, for example, in compartment C, the introduction of liquid 64 and evacuation of waste liquid 66 may takes place at the same time when high concentrations of particulate content is detected in waste liquid 66. The same may be done in compartment F or the entire basin portion A when passing absorbent material 18 enters and exits the liquid catchment means enclosure module J accordhig to direction of arrow 54, Similarly, a reduction of the evacuation of waste liquid 66 may be provided within compartment C whcn the paiiiculate concentration content sensing means detects a low particulate concentration in the waste liquid 66 held within compartment C. In such a moment, the waste liquid 66 may be temporarily halted from leaving the compartment until a certain level of particulate content is reached, or the waste liquid 66 with such low particulate content recirculated around the compartment C to adequately soak or rinse the passing absorbent material 18. An advantage of this aspect helps to save liquid 64 that maybe ordinary water or any other costly liquid such as sanitizing spirit, antiseptic and or disinfectant. However, a standard gap between the rollers 14 and 16 or a gap between the rollers 14 and 16 that that is permanently fixed may work perfectly well. Additionally. use of the particulate concentration content sensing means may govern the amount of introduced liquid 64 or evacuation of the amount of waste liquid 66 away from the liquid catchment means enclosure module J. These mechanisms above operate in either basin portion A or basin portion B and with respect to the direction the passing absorbent material tS passes by.
Preferably. (lie liquid catchnient means enclosure module J may further comprise one or more liquid and debris evacuation or drainage ports disjxc%cd within compartments C, I), E, F, C and 14 for the purpose olevacuating contaminant mixtures of waste liquid 66, spent cleaning fluid, liquid 64, dirt and debris 58. However, in certain embodiments, basin portions A and B or the entire liquid catchment means enclosure module J, may be configured to act as an integral container for retaining the spent waste liquids 66, and the integral container adapted to be easily removable and reinsert-able by the user who manually empties the waste contents when the container becomes full. Thus, the liquid catchment means enclosure module J of the cleaning device JO herein according to FIG 1, includes means for evacuating waste liquid 66 from basin portions A and B through one or more drainage ports 68, 68a, 70,70a, 72, 72a, 74,74a and draining ports 76,76a and 78,78a positioned within the interior of the receptacte surfaces of the of the liquid catchment means enclosure module.1.
The drainage ports 68, 68a, 70,70a, 72,72a, 74,74a and debris draining ports 76,76a and 78,78a are fluidly connected to at least one waste tank K, via at least one conduit element 80. The conduit element SQ may he flexible or an inflexible conduit moulded from plastic or any other suitable material and sufficiently capable to carry particles and debris in either a gaseous and or liquid medium, and at low or high pressure. Within Londuit element 80, there is provided a puffing force or suction force 82a provided by a fanning, pumping or suctioning means 82. The suetioning means 82 draws in liquid, gas and or waste liquid 66 and debris 58 and 59 from receptacles in basin portion A and B thru drainage ports 68, 68a,70,70a,72,72a,74,74a and drainage ports 76,76a and 78,78a in the direction according to arrows Q, R, 8, T, U and V, then depositing the waste liquid 66, dirt debris SR and 59 into waste tank K through the suction force 82a produced within conduit element 80 by suctioning means 82. Suctioning means 82 may form a plenum within an empty space of' waste tank K thereby drawing airflow with waste liquid 66, dirt debris 58, 59 and contaminant solution therein which then fall into waste tank K whilst the airflow passes via one or more filtering element (not shown) before leaving the suctioning means 82. Conduit element 80 may have one or more branches so dirt and debris 58, 59 and waste liquid 66 may be evacuated (by suction force 82a) from one or more compartments C, B, E and F, C, H, and said branches fluidly connected to conduit element 80 which is fluidly connected to waste tank K, (or to disposal location away from the cleaning device via conduit element SOa) and said branches having mouth ends or drainage ports 68, 68a, 70, 70a, 72, 72a, 74,74a and drainage ports 76,76a and 78,78a. Then. may be provided a tank-full sensor (not shown) housed therein waste tank K and be configured to communicate a tank-full signal to the main control unit N when wastc tank K is full. Thusly, there may be provided one or more pressure release valves or air vent opening (not shown) along the conduit element 80 or along any other suitable location such as on the perimeter walk of waste tank K so that suctioning pressure within liquid catchment means enclosure module J, and within conduit element 80 is sufficiently maintained in order to adequately entrain and remove all waste liquid 66, dirt debris 58 and 59 held within any of compartments C, B, E, F, C and Hand without having any pumping or suctioning force fluctuations, interruptions or cessations. Once waste tank K is full, a user may then manually empty the mixture of waste liquid 66, dirt debris 58 and 59 from the waste tank K by unlatehing and removing waste tank K which is configured to be easily removable from the chassis 12 or 12a of the cleaning device 10 by uncapping the removable tank cap 90 which includes conduit 80 fixed there-through. However, in certain embodiments, the cleaning device 40 may be configured to have one or more permanently connected or removable interface element 83 engagingly connected to interface port 84 (according to direction olarrow 85) which then connects conduit elemeut 80 fluidly interposed and connected via conduit SOa to an external suctioning means-fluidly connected to conduit SI so as to remove waste liquid 66 from basin 20 of compartments C. B, E and F, C, H of the liquid catchment means enclosure module J, and to send waste liquid 66 through conduit element 80, via conduit 80a, and via interface port 84, engaged (according to directional arrow 85) to interface element 83 and connected to conduit 81 to a disposal location away from the chassis 12 and 12a of the entire cleaning device 10.
Preferably, there may be provided within the interface port 84 one or more valve mechanism means (not shown) that remains shut until pressed open once the interface port 84 correspondingly mates and engages with interface element 83 according to direction of arrow 85, so that an opening is created when a pushing element (not shown) penetrates either one of said interfaces to fluidly unite conduit 80a and conduit 81 thereby allowing waste liquid 66 to pass through for disposal away from the cleaning device 10. In certain embodiments, waste liquid 66 may be recirculated or recycled and the dislodged dirt and debris collected being removed by conventional filters or other means, so that the retrieved fluid may be reused within the liquid catchment means enclosure module J. Thus, conduit element 80 may become connected or branched to one or more evacuation conduits for the purpose of transporting dirt, debris and conta4linant liquid 58, 59,66 to waste tank K or other waste tank(s) located away from the cleaning device *0 and linked by removable conduits or hoses e.g. conduit 94,for example, wherein the cleaningdevice 10 may be used to cleaning window panes on a skyscraper building, the cleaning device JO may be connected via conduits to the storage tanks containing the clean liquids such as water and for storing the waste liquids, however, the supply conduits (for water, electricity and waste disposal) may be directly connected to the mains electricity, water supply and sewerage of the building.
In a certain embodiment, it may be possible for the liquid catchment means enclosure module J of the cleaning device 10 herein to have one or more liquid urging means, or pair of rollers 14 and 16, and also having either one or more brushing element 56, liquid applicator 60 and drainage port Q.R,S,1',U,V, sharing one or more un-partitioned basin 20 of the liquid catchment means enclosure module.1. One or more sealing element, lining or gasket (not shown) may be configured to be positioned external to the female interface element 83 and or end of male interface port 84, (which then mates with interface element 83) so as to provide substantial airtight and watertight seals between conduit 81, conduil 87 and hydrophobic electric lines 89,89a,94, 94a,94b,94e and sooit In sonic embodiments, cleaning components such as the waste tank K, clean fluid tank M, force of suction from suctioning means 82, and electrical power may be linked and or fluidly connected via an extended bendable hose or conduit 89, 89a, 94,94a, and to the liquid catchment means enclosure module J. Alternatively, portable electrical source such as a battery 95 may be used as an electrical power source for the cleaning device. The battery 95 may be interconnected to the cleaning devices electrical delivery network to numerous components via conduits $9,89a,94, 94a,94b,94c and so on, emerging from one or more electrical junction or electrical distribution point PP. Such electrical currents may have been lowered down or reduced from source by implementing a step down electrical current transformer (not shown).
Thusly, with reference to FIG 3, the overall cleaning head 98 which includes the liquid catchment means enclosure module J may be linked by conduits 89,89a, 94, 94a,94b,94e to cleaning components situated away which may include waste tank K, clean fluid lank M, force of suction from suctioning means 82, and electrical powr, so that conduit 94. is used as clean fluid, electrical power delivery means and also as a means fbr waste liquid 66 and debris evacuation away from the liquid catchment means enclosure module J to the support frame or chassis 96 which supports waste tank K, clean Iluid tank M. soap container L and any other necessary cleaning components for making the cleaning device work adequately. An advantage of this aspect of connecting an extended bendable hose or conduit 94 between the liquid calchment means enclosure module J and container reservoirs waste tank K, clean fluid tank M, is that the weight, height and size of the overall cleaning head 98 when cleaning surface 11 such as floors is reduced so that the overall cleaning head 98 is manoeuvrable into smaller gaps and underneath objects such as coffee tables, low seats and beds.
Also, that the overall cleaning head 98 is easier and lighter to lift by a user when washing vertical surfaces such as bathroom tiles, nylon curtains, walls cars and windows. In certain embodiments of the above aspect wherein conduit 94 connects liquid catchment means enclosure module J and chassis 96.Conduit 94 is fixed to interface element 83 and connects to interface port 84 in the same manner explained in the above examples of FIG 1-2. A user of the cleaning device 10 may carry chassis 96011 straps (not shown) or handle whilst using ove:a11 cleaning head 98 to clean a surface 11, wherein such an embodiment, electrical pow.r to provide energy to the cleaning device 10 may be provided from mains or from a sell-contained power source. However chassis 96 may have swivelling free-rolling or caster wheels (not shown) for allowing self-alignment as the user drags the chassis 96 attached by bendable conduit 94 to overall cleaning head 98, into any direction on a floor or surface It whcn overall cleaning head 98 is in use. Part of the bendabLe conduit 94 is a non-flexible tube (not shown) which is fluidly and rotatably connected between conduit 94 and overall cleaning head 98. The non-flexible tube (not shown) may act as a handle whereby the user of the cleaning device 10 cali control the manoeuvrability of the overall cleaning head 98 from. The rotatable connection between the non-flexible tube (not shown) and the overall cleaning head 98 allow swivelling of the overall cleaning head 98 during use. In a preferred embodiment, wider bendable conduit 94 may act as conduit 81 in schematic example shown in FIG 3, however, for the purpose of illustrational clarity (follow-on); conduit 81 is depicted as a separate element from conduit 94.
Preferably, the power source delivers electrical power to subsystems of the cleaning device 10.
Electric power is delivered to plurality of subsystems o the cleaning device 10 via network of interconnected wires and or conductive elements and controlled by the on-board computer system or main control unit N. [lie entire cleaning device 10 can be powered by either DC or direct current or AC or alternating current electricity and is controlled by the main control unit N. Preferably, the cleaning device 10 can be configurable to be powered by either of both AC and or DC power supply; wherein utilizing AC power supply connects the cleaning device 10 to a mains electric line 89 via plug 100 for power. The power source may include an electrical power interface unit or plug 100 for delivering power to the cleaning device 10 subsystems. In certain embodiments, the cleaning device may have AC electrical interface port for temporary mains electrical cable connection to recharge a self-contained power source; thus, the cleaning device 10 may include self-contained power source configured into the body of the cleaning device 10. The self-contained power source may be rechargeable battery e.g., a rechargeable lithium ion attached to the cleaning device 10. Electrical power is distributed around the cleaning device 10 subsystems to perform various tasks by the overall control of the main control unit N once the user activates a command.

Buttons, dials and visual lights on the user input contro] unit Pare placed conveniently on the handle element 120 and blended to the covering element 124 of the cleaning device 10.
With reference to FIG ii and FIG 13. the covering element 124 may be moulded together or blended with the handle element 120. The handle element 120 allows a user to support the cleaning device tO on the surface 11 being cleaned. There may be provided a slotting means 140 on the handle element or on covering clement 124 for temporarily or permanently inserting or fixing at least one non-flexible tube or elongated handle or extension pole-handle element 141. The extension pole-handle element 141 may act as a handlethereby the user of the cleaning device 10 can control the mauoeuvrability of the overall cleaning head of the cleaning device 10 from. The rotawbie connection (not shown) between the extension pole-handle element 141 and the body of the cleaning device 10 allow swivelling of the overall cleaning head (10) during use. Primarily, the extension pole-handle element 141 allows the user to be able to reach far out, narrowed or high-above surfaces (11) which need cleaning using the cleaning device 10 described herein.

Such communicating means may be radio wave signals connection means, may be used to send or communicate the same commands to and from the cleaning device JO and the extension pole-handle element 141,whilst the extension pole-handle element 141 is temporarily or permanently attached (by user) to the cleaning device 10. Preferably, the extension pole-handle element 141 may be connected and or disconnected from the cleaning device 10 using a quick release dick-in and click-off mechanism which latches or locks the extension pole-handle element 141 securely in place. Such a mechanism may have a leverage button conveniently placed at the extension pale-handle element 141. Preferably, such a leveraging button is manually actuated. The extension pole-handle element 141 may have the capability to be bendable or articular. This articulation is preferable at the base of the extension pole-handle element 141 closest proximity to the cleaning head of the cleaning device or nearest to the extremity or end opposite the handle portion of the extension pole during use of the cleaning device 10. Prefbrably, the articulation of the extension pole-handle element 141 may allow a variety of different surface planes, gradients and flat surface above heights to be reached and cleaned by the independently' moving or swivelling head of the cleaning device 10; wherein such surfaces (11) are reached and cleaned sufficiently may include and not limited to; flat surfaces ((1) above the height of the user of the cleaning device 10, swivelling of the cleaning head rotatably attached to the extension pole-handle element 141 so that the cleaning device 10 can easily reach around furniture, baseboards or skirting boards, narrow gaps and tight corners, flat surfaces above a user's height, when cleaning various surfaces (11) in a domestic or commercial environment. One advantage of the cleaning device 10 extension pole-handle element 141 is its capacity to lengthen or shorten the pole-handle so that the extendable or telescopically adjustable handle pole or boom provides extra safety and comfort by suiting both the user and the cleaning surface 11, so as to reach various surfaces such as high up window panes, horizontal and or vertical surfaces in narrow spaces.
The telescopic means of the extension pole-handle element 141 may have pivotal or a rotating neck (not shown) to, say for example 1400 degrees for allowing the cleaning device JO to gain cleaning reach upon flat Level surfaces above the height of the user.
In alternative embodiments, the extension pole-handle element 141 may be configured to act as both the user's support means for the cleaning device 10 upon the cleaning surface 11 and also for supporting other cleaning components of the cleaning device 10; such as waste liquid and debris container tank K, clean fluid container M, soap container L, vacuuming elements, suctioning means 82, pumping elements W, associated conduits and electrical components.
With reference to FIG 1-4, the absorbent material 18 is attached to disc 19 which rotates around axis 102. At axis 102, the disc 19 is rotatably fixed to chassis 12 by suitable means so that continuous rotation of the absorbent material IS is achieved at either clockwise or anticlockwise direction.
Rollers 14 and 16 provide the energy to rotate the absorbent material IS attached to the disc 19.
However, in some crnhodiments, the energy to rotate the cisc 19 may be provided from the point of axislO2. In some ernhodiment, the support.sfructure of the absorbent material IS may be a flexible belt, a Ilexible loop, a cylinder, a non-flexible ring, a flexible disc or a non-flexible disc. Thus the support structure may rotate concentrically or revolve eccentrically whilst supporting the absorbent material entering and (caving the liquid catchment means enclosure module J for regeneration. The support structure according to FIGS 1-4 is a disc 19 whereto the absorbent material 48 is attached.
With reUrcnce Lo FIG I, FIG 2 and FIG 4 (plan view of the cleaning device facing the frornhtbrward direction of arrow 101). the cleaning device 10 is in contact with a surface 11 and supported thereupon by one or more wheels 104. However, in some embodiments, the cleaning device 10 may be supported on surthce 11 without wheels 104. Preferably, the absorbent material 18 also touches or lies in contact with cleaning surface 11, however, the absorbent material 18 may be retractable or can be raised away from the cleaning surface 11 whilst the rest of the cleaning device 10 remains supported by wheeLs 104 on the cleaning surface 11.
With reference to FIG 4, during regeneration of the absorbent malerial 18, the absorbent material 18 is fixed to disc 19 and travels around axis 102 so that part or portion of the absorbent material 18 remains constantly enclosed within the liquid catebment means enclosure module J whilst portion of the body of the absorbent material 18 remains exposed and in contact with surface 11. Motive energy is delivered to the drive motor 22 via electric line network (shown in dotted tines) connected to electric line 89a. Motive energy to rotate the absorbent material 78 around axis 102 is provided by drive motor 22 which rotates spindle 25, Spindle 25 is fixed to gearwheel 24. Gearwheel 24 meshes with gearwheels 26 and 28. Gearwheel 26 is fixed to spindle 30, while gearwheel 28 is fixed to spindle 32. Spindles 30 and 32 are fixed to rollers 14 and 16 so that when gearwheel 24 rotates at the direction of arrow 23, causing gearwheel 26 to rotate in the opposite direction shown by arrow 27.
thus gearwheel 26 causing gearwheel 28 to rotate at the opposite direction shown by arrow 29, thereby causing portion of the absorbent material 18 which is held in compression force or sandwiched along the lengths of the surfaces of rollers 14 and 16, and to move in between the rollers 14 and 16 at direction of arrow 54.
With reference to FIG I and FIG 4, as the cleaning device 10 is moved across a cleaning surface 11 according to arrow 101. portion of the exposed absorbent materia) 18 maintains contact with surface 11 as the absorbent material 18 constantly rotates around axis 102 and in the direction of arrow 54.
This action causes the absorbent material iS to leave behind a clcaning width 106 on cleaning surface 11 as the cleaning device 10 is moved at direction of arrow 101. Preferably, the widest cleaning width 106 lootprint is suitably attained when the,semi-circular portion (of the absorbent material IS attached to disc 19) is exposed so that face 17 of absorbent material 18 meets cleaning surface lifrom the location of the transverse line 108 and extending rearward/aft in the direction of arrow 110. However, in other embodiments of the invention described herein, the support structure maybe flexible belt or loop which eccentrically or concentrically revolves and or rotates affixed absorbent material so that the cleaning width may be increased and effectually configured to follow angular edges of the cleaning device's cleaning head.
Thereto, for the cleaning device 10 to successfully clean surface 11 effectively, regeneration or restoration of the absorbent material 18 to its original or restored condition (so that it can be reused to clean the surface) has to take place at the same time as the absorbent material 18 continuously or constantly travels in the direction of arrow 55, and comes into contact with the surface 11 collecting contaminant dirt and debris 58 from said surface 11 via cohesion, absorption and adherence causing the absorbent material 18 to accumulate contaminant dirt and debris 58 on and within the body and face 17 of the said absorbent material 18 making said absorbent material 18 to become polluted, dirty or degenerated before entering the liquid catchment means enclosure module J according to arrow 54 via aperture 38 thr regeneral ion or restoration. At this particular stage wherein the permeable body and lce 17 of the absorbent iiiatcrial 18 carries contaminants dirt and debris 58 and travels in direction of arrow 54, and is about to enter said liquid catchment means enclosure module.1 via aperture 38 for regeneration, said absorbent material IS is referred to as being in a dirty or degenerated condition.
Thus, the regeneration of the degenerated absorbent material 18 occurring within the liquid catchnient means enclosure module J has to be performed continuously and rapidly For said absorbent material 18 to maintain cleaning said surface 11 effectively. To achieve this, said absorbent material IS needs to be continuously rotated around axis 102 and at the direction of arrow 54, so that as portion of said absorbent material 18 makes contact with surface it. portion of said absorbent material 18 enters the liquid catchment means enclosure module J via aperture 38 for regeneration and also, portion of said absorbent material 18 exits liquid catchnient means enclosure module 1 via aperture in a regenerated clean and dry state to resume contact with surface 11, and the cycle continues.
Thus, when the cleaning device lOis in use, continuous cleaningof surface 11 and regeneration of the said absorbent material iS occurs simultaeously and without ceasing or stopping. In some embodiments, die pace in which the regeneration of the absorbent material 18 occurs may depend various upon factors such as the concentration and level of adherence of contaminant matter on the cleaning surface, the amount of waste liquid, or dean fluid and or soap on the cceaning surface, or the speed at which the cleaning device 10 is passed over the cleaning surface 11. Thus, in certain embodiments, the speed in which the absorbent material 18 rotates around axis 102 may be automatically or manually controlled or governed.
While the absorbent material ISis in a degenerated or dirty condition or state, no effective cleaning of surface 11 may take place when the absorbent material 18 is passed over the surface 11, unless the body and face 17 of the absorbent material 18 is restored to a clean and semi dry condition via cleaning. Cleaning (he absorbent material 18 involves removing contaminant dirt and debris 58 that is prcviousl collected by the absorbent material 18 from cleaning surface II so that the degenerated absorbent material 18 is transformed into a regenerated or restored absorbent material 18 which can then he reused to continuously clean surfad ii Therefore, as the degenerated or dirty absorbent material 18 carrying contaminant dirt and debris 58 from surface II travels according to direction of arrow 54, and around uxis 102.it continuously enters the liquid catchment means enclosure module.1 via aperture 38, delivering contaminant dirt and debris 58 into compartment H. Thus, once portion of the absorbent material 18 enters the liquid catchment means enclosure module.1 via aperture 38 and is within compartment H, wherein successive regeneration or restoration cleaning steps (which are the conventional basic cleaning steps widely used) when cleaning an object are carried out within the liquid catchment means enclosure module J to clean the absorbent material 18. These steps may include one or more or the combination of 0) removing dirt and debris from the object, (ii) soaking and washing an object (iii) rinsing the object (iv) and drying the object. However when regenerating the absorbent material 18 within the liquid eatchment means enclosure module 3, certain steps may be eliminated, added or extended and still attain the equivalent result ofa clean dry or semidry absorbent material 18, or so long as the absorbent material 18 can be reused continuously to clean the surface 11 appropriately by the cleaning device 10 described herein. The cleaning steps undertaken within the Hquid catchrnent means enclosure module 3 begin when t:.e absorbent materiaS 18 enters the liquid catchment means enclosure moduic J via antrturc 38 to encounter scraping means in the form of roating brush 56 which begins the process of removing impurities din and debris 58 from the face 17 and permeable body of the absorbent material 18. The rotating brush 56 shears and dislodges loosely held particles and debris 58 from the portion of the passing absorbent materia 18 by rubbing off or flicking dirt and debris 58 from the face 17 and body of the absorbent material 18. Dirt and debris 58 is then evacuated from compartment H by suction force 82a in the direction of arrow Q via drainage port 76,76a for disposaL Next, and with reference to FIG land FIG 4, as portion of the absorbent material 18 now free from dirt and debris 58 travels further into the liquid catchment means enclosure module J, apex or inner-walt 42 compresses and temporarily alters the shape of the resilient body of face 17, thereby removing contaminant liquid and debris 58, before portion of the brushed absorbent material 18 proceeds to enter into compartment G. Once portion of the absorbent material 18 is within compartment 6, liquid applicator 60 discharges or ejects liquid 64 in the direction of arrow 63 and onto face 17 of the body of the absorbent material 18. Preferably, fluid 64 may be clean fluid such as water; however, Fluid 64 can he any other type of fluid. Discharged, squirted or sprayed liquid 64 flushes. cleanses and soaks into the body of the absorbent material 18 thereby rinsing, dissolving, diluting, loosening and dispersing contaminant particulates collected from surface LI, and including mixtures of dirt 58 and waste liquids 66 held within the porous body of the absorbent material 18 and sending said dislodged contaminants in a direction away from the permeable body and face 17 of the absorbent material 18. Waste liquid 66 is then evacuated from compartment C by suction force 82a via drainage port 68, 68a and in the direction of arrow R. At this stage, portion of the absorbent material 18 in compartment C is soaked wet and waiting to be wrung. As portion of the absorbent material 18 leaves compartment C, apex of inner wall 43 compresses and temporarily alters the shape oFthe resilient body ofthc absorbent material 18, entering into compartment F. Apex of inner wall 43 also helps to further remove waste liquid 66 which is a mixture of liquid 64 and contaminants, debris and dissolved particles (collected from surface 11 by passing portion of the absorbent material 18) which are prevented from further adhering on or within the body of the absorbent material 18, or otherwise reaching compartment F. Once the soaked portion of (he absorbent material 18 is in compartment F, dissolved and diluted mixtures of particles dirt and debris 58 and 66 are removed from the rinsed face 17 and body of the absorbent material IS by the forceftd action oIiquid applicator6O ejecting fluid 64 on the face 17 and permeable body of the absorbent material 18. the compressing action of apex of inner wall 43. Also combined action of' apexes of inner-walls 42 and 43 increases the expulsion of spent mixtures of contaminant dirt and debris 58 and or waste liquid 66 from the face 17 and body of the absorbent material 18. However, the absorbent material 18 is still soaked with diluted spent liquids (mixture of liquids 64. spent washing liquids, contaminants and debtis collected from surface 11) thus incapable of wiping dry or adequately cleaning surface II. Therefore, the soaked absorbent material 18 at this stage and within compartment F needs to be wrung so that the spent liquids held within the porous body may be removed from said absorbent material 18 so that said absorbent material iS may be, transformed from a wet to a clean dry or semidry condition. Wringing the absorbent material 18 is crucial as once spent liquids held within permeable body of said absorbent material 18 are removed, said absorbent material 18 is left in a clean dry and or semidry state, ready to exit the liquid catchment means enclosure module J via aperture 40, and resume contact with surface 11 for adequate cleaning.
ihus, as portion of the absorbent material 18 progresses fu1ther in the direction of arrow 54, through and away from compartment F and into com?artment E, rollers 14 and 16 located lengthwise along central wall 44 so that portion of the absorbent material 18 becomes sandwiched and gripped in-between the compressing force of the surfaces of rollers t4 and 16, (rotating in the direction of arrow 27 and 29 respectively) moving the sandwiched absorbent material 18 in direction of arrow 55.
These combined compressing and pulling action by rollers 14 and 16 temporarily compress portion of the resilient porous body of the absorbent material 18 forcing the spent mixtures of contaminant waste liquid 66, fluid 64 and dissolved particles therein to be expelled from the permeable body and face 17 of the absorbent material 18, so that as portion of the absorbent material 18 emerges (whilst regaining shape) From the other side (or basin portion B) of the rollers 14 and 16 and into compartment E, said absorbent material 18 is in a clean dry and or semidry condition. Thusly, the degenerated portion of the absorbent material 18 previously in compartments F is now in compartment F having been transformed into a regenerated or restored condition ready to become reused by the cleaning device 10 to clean surface 11. Once in compartment E, the restored or regenerated absorbent material IS (now ready to be reused) is in a dry or semidry condition and travelling in the direction of arrow' 54. towards aperture 4Oso as to exit the liquid catchment means enclosure module I, and regain comact with the cleaning surface Ii in order to perforrri suitable cleaning on said surface. However, the absorbent material 18 has to continue travelling (in the direction of arrow 54) through compartments U and C of basin portion B which preferably is a mirrored reflection of basin portion A. In some embodiments, the cleaning device 10 may have basin portion A only, making the absorbent material to travel in one direction only, e.g. in direction of arrow 54 only so as to perform suitable cleaning on surface 11. Thus, with reference to FIG I and FiG 4, the regenerated absorbent material 18 which now is in compartment E and encounters apex of inner-wall 45 temporarily altering the shape of the resilient permeable body ofthe absorbent material 18 before entering into compartment D. Meanwhile, any remaining spent liquids arid or debris which apex 45 may have scrapped away or forced off from the passing portion of the absorbent material IS is evacuated from compartment E by suction force 82a ibm drainage port 72,72a and in the direction of arrow T. Portion of the absorbent material 18 then proceeds to enter the following compartment D wherein liquid applicator 62 is disabled so as not to soak or drench the clean regenerated dry or semidry absorbent material 18 which then proceeds to leave compartment band enters compartment C in the same manner (us in preceding comrtments) and after being temporarily compressed by apex ofinner-all 47. Any remnants of spent liquids, waste liquid 66 and or debris 58 removed from the lbce 17 and permeable body ol' the absorbent material 18 by apex 47 are evacuated from compartment D (by suction force 82a) in the direction of arrow U via drainage port 74,74a. As the absorbent material 18 proceeds in the direction of arrow 54, and cntering into compartment C. rotating brush 57 fixed therein brushes face 17 and body of the absorbent material 18 so as to remove any remaining debris, or dirt particles that may be still clinging on. Preferably, the rotating brush 57 rotates in the direction opposing that of the passing absorbent niateria IS so that any dirt, debris and particles which may still be clinging onto the body and or face 17 of the absorbent material 18 are removed and evacuated from compartment C by suction force 82a thru drainage port 78,78a and in the direction of arrow V. From here (compartment C), the clean regenerated dry or semidry absorbent material 18 leaves the liquid catchment means enclosure module J via aperture 40 to recommence contact with the cleaning surface II, and the cycle continues. The same process to regenerate the absorbent material 18 as described above takes place when the absorbent material 18 travels through the liquid catchment means enclosure module,jn the direction opposite that of directional arrow 54,so that the steps or processes performed in basin portion A (when absorbent material IS moves in direction of arrow 54) arc successively repeated in basin portion B (when the absorbent material 18 moves in direction opposite that of arrow 54), and also, steps or processes performed in basin portion B (when absorbent material 18 moves in direction of arrow 54) are successively repeated in basin portion A (when the absorbent material 18 moves in direction opposite that of arrow 54). Apexes of the innerwalls 42, 43, 45 and 47 perform the equivalent task of removing spent contaminant waste liquid and debris as well as keeping individual or respective compartmcnts H. C, F, E, D and C free from impurities (and or chemicals and gases) contained within said neighbouring compartments.
Aperture lips 39 and 41 also act to itthibit spent liquids and or debris from leaving the liquid catehment means enclosure module J in whichever direction the absorbent material 18 travels in when exiting the liquid catehment means enclosure module 3 via aperture 38 or 40. Aperture lips 39 and 41 arc receptively formed to enable flowing entry of the absorbent material 18 (carrying spent liquids and contaminant matter) into the liquid eatchmcnt means enclosure module 3 in either * direction die absorbent niaterial iS travels in when entering the liquid catchment means enclosure module J via aperture 38 or 40. and also without causing the spent liquids and contaminant matter held within the permeable body oF absorbent material 18 to drip or leave the absorbent material IS beibre said absorbent material 18 enters the liquid catchnient means enclosure module 3 for regeneration.
Preferably, all drainage ports 68,68a,70,70a,72,72a,74,74a,76.76a,78,lSa are molded and configured to evacuate waste liquids dirt and debris, such as from compartments H and C, drainage ports (76,76a, 78,78a) therein are wide enough and configured to suitably maintain an adequate negative pressure of suction force 82a within compartments Hand C so that effective evacuation of dirt and debris from the passing body portion of the absorbent material 18 takes place therein. In a certain embodiment, it may be possible for the liquid catchment means enclosure module J of the cleaning device herein to have one or more liquid urging means, having either one or more; brushing element 56, liquid applicator 60 and drainage ports 68,68a and 70,70a sharing a single un-partitioned basin 20 of the liquid catchment means enclosure module J. In order to maintain the cleaning elemcnt-(wch is the absorbent material 18 in this example) in a clean regenerated state for the purpose of continuously cleaning a dirty surface, the progressive cyclical principal successive steps of either; cleaning a dirty surface using the cleaning element (18), then followed by rinsing the cleaning element (18), then followed by removing the rinseate or rinse-offliquid from cleaning element (18) which is usually the final step of the regenerating cycle, so that it is now possible to successfully clean the surface once again using the now regenerated cleaning element (18) has to be maintained continuously within the liquid catchment means enclosure module J, of this patent disclosure is paramount to the workings of the cleaning device 10. However, it may now be apparent that there may be a number of other ways in which the cleaning element (18) operating within a surface cleaning device as disclosed in this patent, may be regenerated or rinsed off to rid it from the contaminants or dirt accumulated from contacting the cleaning surface prior to recurring contact with a surface being cleaned during the cleaning cycle of the cleaning element (18) in the cleaning device 10, such as by applying a rinsing fluid and or cleaning fluid (64) using liquid applicators (60) along the passing cleaning element (18) at a certain convenient predefined position that may he within or not within an enclosure.and before the cleaning element (18) passes via a liquid urging means. before re-emerging to recur contact with the cleaning surface. Another means to regenerate the passing cleaning element (18) may be done by adapting the liquid applicators (60,62) operating in the cleaning device 10 to apply a clean fluid onto the cleaning surface prior to the cleaning element (18) working within the cleaning device 10, collects the mixture of waste liquid (66) and spent cleaning fluid from the cleaning surface (11), leaving the cleaning surface(11) in a substantially clean and dry state, is synonymous to rinsing or regenerating (as herein disclosed) the cleaning element (18) to achieve, or as it achieves the equivalent result. Other means to regenerate a cleaning element such as the cleaning element (18) using a clean fluid as a rinsing element for the purpose of constantly regenerating or removing contaminant substance collected from a cleaning surface by the cleaning element operating within a cleaning device 10 as disclosed in this patent is equivalent to regenerating the cleaning element for continuous cleaning upon a cleaning surface by -ft the cleaning device 10 and in particular to the regeneration of the cleaning element which makes final or last contact with a cleaning surface across a cleaning width, leaving the cleaning surface in a substantially dry and hygienic state, may thus he performed directly to the cleaning element or indirectly and still achieve the same anticjpated results of reusing the same cleaning element conitnuously or without cessation when cleaning any surface using the cleaning device herein described in this patent disclosure. Similar, one or more of named parts and or aspects modified to provide the said results as disclosed herein this patent disclosure ate known and obvious.
Thus, in certain embodiments of the cleaning device 10 herein, the only process necessary for regenerating a dirty cleaning element (which is the absorbent material IS in this example) can be carried out by applying clean fluid (64) such as water onto the cleaning element (18), before applying liquid urging means (which are the rollers 14 and 16 in this example) onto said cleaning element (18), so that said cleaning element (iS) is rinsed and then wrung to release the waste mixture from the cleaning element (IS) so that the cleaning element (18) is transformed from a dirty and soaked cleaning element (18) to a clean and dry cleaning element (18) ready to recommence cleaning dirt and debris and absorbing dirty or contaminated liquid from a surface. However, it may be possible to bypass the application of clean fluid (such as water) directly onto the cleaning element (18) in orderto rinse it prior to applying liquid urging means on said cleaning element (18). Bypassing direct application ofa clean fluid (such as water) on the cleauiing element (18) may be done by configuring the cleaning device lUto spreading cleaning fluid (64) (such as water) on the cleaning surface (11), prior to passing the cleaning element (18) over said surface (11) so that said cleaning element (18) absorbs said clean fluid (64) thereby rinsing, soaking, dissolving, diluting and loosening dirt and debris from the body of cleaning element (IS) and surface (ii) prior to(18) passing Eru the liquid urging means (rollers 14 and 16) for expulsion of the mixture of waste liquid (66) from the body of the cleaning element (18) before the cleaning element (18) can be reused to clean a surface (II) continuously. The rinsing liquid (64) such as water may be lightly soapy so as to simultaneously act as rinsing liquid in order to dilute liquids and dissolve contaminants held within the cleaning element (18) as well as wash and rinse surface 01). Thus, liquid (64) may be spread on the cleaning surface (11) in order to rinse and dean the cleaning element (18) prior to the cleaning element (18) passing through liquid urging means (which are the rollers 14 and 16 in this example) for regeneration.
Thus. in summary and with reference to FIG I to FIG 4, the absorbent martial 18 continuously travels via the liquid caichnient means encloii'c nioduled in the direction of arrow 54 and around axis 102 whilst being fixed upon support structure disc 19 so that portion body and face 17 of said absorbent material 18 makes continuously contact with surface 1%, thereby collecting mixtures of spent cleaning fluid and rinsing fluid, dirt and debris 58 and contaminants therefrom (surface 11), leaving said surface Ii in a clean and dry condition, before the absorbent material 18 re-enters aperture 38 for regeneration within the liquid catehrnent means enclosure module J. In the liquid catehment means enclosure moduleS the absorbent material 18 carrying collected mixtures of spent creaning fluid and rinsing fluid, dirt and debris 58 goes through a series of cleaning steps that may include washing and drying so that once the absorbent material 18 re-emerges from the liquid caichment means enclosure module J via aperture 40, said absorbent material 18 is in a clean dry or semidry condition, ready to perform the cycle of making contact with the surface It and to collect mixtures of spent cleaning fluid dirt and debris S8 before said absorbent material 18 re-enters the liquid catchment means enclosure module 1 once again for regeneration or restoration, and the cycle continues without stopping during use as the cleaning device 10 is moved across the cleaning surface.

With reference lo Fit; 5 to FIG 13, the base 122 of the cleaning device 10 may carry a first cleaning region 130, and a second cleaning region 134. The first cleaning region 130 may comprise cleaning components arranged to collect loose particulates and debris from the cleaning surface II across cleaning width 106. The cleaning components of the first c)eaning region 130 may utilize a scrubbing component. The scrubbing component may be positioned (at the base 122 and in contact with object surface 11) on the front, rear, left and or right side of the chassis of the cleaning device 10. Preferably, the cleaning components is cylindrical in shape, however, it can be disc-shaped, semi-spherical or a block, and may be made from any flexible, soft absorbent or non-absorbent material which it is durable-has high abrasion resistance thus it's strong and hardwearing and can be eccentric or concentric. Preferably, the scrubbing component is a scrubbing material 132 is made from a permeable spongy material, alternatively scrubbing material 132 can be made from brushes, wool, mitts, steel wool, nylon, abrasive material, microfibcr cloth, cotton, scouring pad etc. The scrubbing material 132 supported on a spindlc 133 revolving or rotatably fixed on the base 122 of the cleaning device.
With reference to FIG 11 section D-D, the cleaning components of the first cleaning region 130 may utilize a vacuuming or suctioning means 82 producing suction force 82a via negative vacuum area 112 sandwiched by outer lip element 114 and inner lip element 116 disposed on the transverse and perpendicular peripheral edge of the base 122 so that the cleaning device 10 is configured to suction up loose particles and debris from the cleaning surface 11; and wherein the arrangement of the negative vacuum area 112 with respect to the scrubbing material 132 may cause the negative vacuum area 112 to precede the scrubbing material 132 over the cleaning surface It when transporting the chassis 12a in a forward direction 101. Alternatively, the cleaning components of the first cleaning region 130 may utilize brushes (not shown) to sweep the loose particulatcs into a receptacle or otherwise remove the loose particulates from the cleaning surface It. The first cleaning region 130 may also carry a surface-liquid applicator 136 arranged to apply a cleaning fluid 137 onto the surface 11. Preferably, the scrubbing material 132 attached to the base 122 of the chassis is configured to agitate and dislodge contaminants adhcrcd to the cleaning surface I via a scrubbing action.
The scrubbing material 132 contacts the cleaning surface 11 during cleaning operations of the cleaning device 10 and agitates the cleaning fluid 136 to mix it with surface 11 contaminants to emulsiFy, dissolve or otherwise chemically react with the contaminants. The scrubbing material 132 also generates a shearing force as it moves with respect to the cleaning surface 11 and the force helps to break adhesion and other bands between contaminants and the cleaning surface 11. In addition, the scrubbing material 132 may have one or more passive elements such as a scraper (not shown) attachment on base 122 and in contact with surface ii and configured to agitate contaminants stuck on the cleaning surface 11 when the cleaning device 10 is moved across, to and fro the cleaning surface 11 during cleaning operation. In one embodiment of the present invention, a passive scrubbing component is attached to the base (122) of the chassis of the cleaning device 10 and disposed to contact the cleaning surface (11) across the cleaning width (106). A force is produced between the passive scrubbing component and the cleaning surface (11) as the chassis of the cleaning device (10) is transported in a forward, backward or sideways direction. The passive scrubbing material 132 and or active scrubbing material 132 may comprise a plurality of scrubbing bristles held in contact with the cleaning surface 11, are woven or are non-woven materials e.g., a scrubbing pad or sheet material held in contact with the cleaning surface ii, or a compliant solid element such as a sponge or other compliant porous solid foatrelement held in contact with the cleaning surface 11.
The scrubbing material 132 may he configured in he replaceable by a user. in certain embodiments, an ultra-sonic sound emitter may also bc used to produce scrubbing action.
Preferably, surface-liquid applicator 136 is configured to simultaneously apply cleaning fluid 137 onto the cleaning surface 11 and scrubbing material 132 or configured to apply or sprays cleaning fluid I37onto the scrubbing material 132 which in turn smears and agitates the applied cleaning fluid 137 to mix it with contaminants on surface it. emulsifying, dissolving or otherwise chemically reacting with the contaminants. The surface-liquid applicator 136 is arranged symmetrically outward from centre along the entire width (108) of transverse axis of the base (122). In certain other embodiments, the scrubbing material (132) may centrally positioned and be disc-shaped and may have a disc-shaped support structure which is rotatably fixed to the base of the cleaning device and wherein the surface-liquid applicator (136) delivers cleaning fluid (137) via rotary jointed conduit connecting the base (122) and the support structure (19) of the scrubbing element.
The second cleaning region 134 may utiliz cleaning components configured to wipe or dry the cleaning surthcc IL Absorbent material IS nay he positioned (at the base 122 and in contact with object surface Ii) on the flout, rear, left and or right side of the chassis of the cleaning device 10.
Preferably, the absorbent material 18 can be disc-shaped. however, the absorbent material 18 can be cylindrical, semi-spherkal or a block, belt-shaped or any other suitable shape and may be made from any flexible, soft absorbent flexible resilient material which it is durable and has high abrasion resistance thus if's strong and hardwearing and can revolve and or rotate eccentrically or concentrically. Preferably, the absorbent material 18 is made from a permeable spongy material, alternatively absorbent material 18 can be made from an absorbent flexible resilient material such as wool, mitts, nylon, leather, ruicrofiber cloth, cotton etc. The second cleaning region 134 may also carry a surface-liquid applicator 138 arranged to apply a cleaning fluid 1139 onto the surface I l.Cleaning fluid 137 and cleaning fluid 139 may be drawn from storage tank M and administered with soap as required. For example, soap from a soap container Lean be administered as required to the water by intercepting the line or fluid conduit for water with additives such as soap or other dirt emutsilying detergent before the water reaches the outlet of the surface-liquid applicators 136 in the luSt cleauin region 130 and abo in the 5econd cleaning region 134 and surface-liquid applicator 138.
Thus when necessary, plain or pure water cabc used for rinsing in the second cleaning region 134 and also in other processes in other parts within the cleaning device 10, such as in the liquid catebment means enclosure module J, and soapy water solution can be used for scrubbing the surface 11 on the first cleaning region 130, before object surface 11 is rinsed and dried by the absorbent material 18 in the second cleaning region 134 during cleaning operation by the cleaning device 10 described herein this patent disclosure. Cleaning fluid 137 may be pumped from the source storage tank M or delivered to the outlet of surface-liquid applicator 138 and or to outlet of surface-liquid applicator 136 via gravity once a valve liquid release mechanism (not shown) is actuated, however, a pump may be utilized instead. The first cleaning region 130 may also include cleaning components configured to scrub the cleaning surface 11; and wherein the arrangement of the scrubbing material 132 causes the surface-liquid applicator 138 in the second cleaning region 134 to follow the scrubbing material 132 over a cleaning surface 11 when transporting the cleaning device 10 in a forward direction 101. Because the cleaning device IC illustrated has a clean liquid tank M and a dirt and debris mixed with waste liquid tank 1< mounted side by side on the cleaning device 10, one major advantage of this and following various embodiments of the present invention below include the fact that The cleaning device is a self-contained-unit which includes clean liquid such as water and there is no need to carry around heavy buckets of water or cleaning implements such as mops and sponges or hose pipe connections. In addition, the problem of contamination of clean liquid such as water is eliminated and any extended surface 11 such as a floor or vehicle is left clean and virtually dry after a single pass with the cleaning device 10 herein. The cleaning device 10 is easily cleanable and the clean liquid M and waste tanks K are removable from the cleaning device 10 and following other embodiments below.
In certain embodiments, the negative vacuum area 112 may be further extended or become introduced and or disposed adjacent the tiNt cleaning region 130 and the second cleaning region 134 or bordering-in-between the scrubbing material 132 and the surface-liquid applicator 138 in the second cleaning region 134 so as to suck up the spent waste liquids and the dirt prior to the surface being rinsed by the surface-liquid applicator 138 in the xond cleaning region 134, or otherwise collected and surthce 11 dried up by the foowing absorbent material 18 in the second cleaning region 134, Preferably, (lie first cleaning region 130 may be positioned centrally and symmetrically mirrored outwards from the midpoint of the transverse axis and along the base 122 of the cleaning device tO.
Similarly, passing absorbent material 18 being supported on a pivotal support means (not shown) which may extend the absorbent material 18 to contact surface 11 or retract absorbent material 18 from contact with surface II as shown by directional arrow 21. These oscillating mechanical means allow for separate vacuuming and wet cleaning applications to be performed on the cleaning surface 11 by the cleaning device 10. In other embodiments, the oscillating mechanical means allow -p alternating vacuuming and wet cleaning operations during forward and backward passes of the cleaning device 10 upon the cleaning surface 11. for example; wherein the arrangement of the absorbent material (18) causes the transverse peripheral vacuuming port to precede the absorbent material (IS) in contact with surface (Ii) when transporting the cleaning device 10 in a forward direction, and the opposite action occurs when the cleaning device lOis transported across the surface (11) in a backward direction so that the absorbent material (18) in contact with surface (11) follows the transverse peripheral vacuuming port when the cleaning device 10 is transporied along the surface (II) in a backward direction. Urns, the oscillating mechanical means allows sufficient cleaning efficiency at whichever direction thc cleaning device 10 is transported across a cleaning surface 11 during a cleaning cycle. Preferably, peripheral perpendicular vacuuming ports are fluidly connected to the transverse perpendicular vacuuming ports having negative vacuum area 112.
The cleaning device 10 may therefore include a negative pressure region or vacuum area 112 defined by a flexible or non-flexible skirt or seal member comprising an outer lip element 114 and an inner lip element I 16,ahout the exterior of the peripheral chamber on a cross-section, and the seal member in cooperation with the surface 11; means for affecting the surface 11, the means (fixed inside and or outside the negative pressure region) being means such as a jetting nozzle, scrubbing component, scouring element, grinding element, brushing element or cleaning material for scrubbing surface 11, and means capable of moving cleaning device 10 along the object surface Ii while keeping the distance between the flexible skirt or seal member [14, 116, and the object surface 11 at a desired and or suitable level. Wheels 104 may be applied to carry the cleaning device 10 across the cleaning suthice II so that the distance between the surface 11 and the seal member 114,116 may be regulated by manually or electronically adjusting level of wheels 104, One advantage of this feature is to prevent the hcad of the cleaning device 10 from getting stuck on the cleaning surface 1! during operation ol the suction force SZa, arid also to allow dirt and debris 58, 59,66 to gain access into the negative pressure region or vacuum area 112 so that suction force 82a forces the dirt and debris inward towards conduit element SO, leaving the surface ii in a clean state.
In some embodiments a magnetic element (not shown) may be used instead of wheels 104, for example where the underlying surface been cleaned using the cleaning device 10 is magnetic and on a steep or vertical orientated plane such as vehicle side surface. in yet another embodiment, the flexible skirt or seal member of the outer lip element 114 and the inner lip etement 116, may be perforated or furrowed at the rim or edge which comes into contact with the object surface 11 so that high air velocity is developed between the perforated or recessed rim and surface 11 to provide improved entrainment and removal of spent cleaning fluid and dislodged debris rushing into the negative pressure area in between the outer lip element 114 and the inner lip element 116. Because the vacuum is applied to a smaller chamber and because the cross-sectional area between outer lip element 114 and the inner lip element I lb is signi flcantlysnalle:; high air velocity is developed between the outer lip element 114 and the inner lip eJement 116 across the peripheral chamber without fear that cleaning device 10 will suck down and becomes temporarily stuck on surface 11. Air velocity suction force 82a within conduit element 80 must be sufficient to entrain and or remove the spent cleaning fluid 5t59 and dislodged debris 66 from cleaning object surface 11 and depositing waste liquids 66 mixed with dirt and debris 58.59 into waste tank K. Conduit element 80 is fluidly connected to drainage ports 6$,68a,70.70a,72,72a,74.74a,76,76a,78, and 78* for evacuation of waste liquids 66 from licuid catchment means enclosure module.1 and into waste tank K by suction force 82*. Thus, conduit element 80 from drainage ports 68,68a.70,70a,72,72a,74,74a,76,76a.78. and 78a may be fluidly connected into waste tank K. In another embodiment, conduit element 80 may be branched and fluidly connected to provide suction force 82a to one or more other compartments in the cleaning device 10. A manual or automatic valve control means (not shown) may be positioned at the intersection for deciding where the suction force 82a is directed.

The suctioning means $2 may also be a liquid pump or both liquid and gas pump.
In yet another embodiment, a manual or auto-electronic pressure control valve (not shown) for suction gas may be placed between the negative pressure region 112 and the vacuum source 82. One advantage of this feature is when using the cleaning device herein to clean walls and windows in high rise buildings and skyscrapers. In yet some other embodiments, clean lug components such as ajetting nozzle, scrubbing component, arbitrary support wheels, scouring element, grinding element, brushing element or cleaning material may be configured to operate inside the negative pressure region, for example. surIace 11 may be cleaned by the absorbent matrial 18 fixed inside the vacuum area 412.

The support structure according to FIG. 14 to FIG. 41 is annular or ring shaped structure 219 whereto the absorbent material 218 is attached.
With reference to FIG (4, FIG 16 to FIG 21 the absorbent material 218 is in contact with a surface II and supported thereupon by one or more wheels 104. However, in some embodiments, the cleaning head 210 may be supported on surface 11 with wheels 104. Preferably, the absorbent material 218 also touches or lies in contact with cleaning surface 11, however, the absorbent material 218 may he ntractablc or can he raised away from the cleaning surface ii via member 279 whilst the restoftlie cleaning head 210 remains supported by wheels 104 on the cleaning surface 11.
With relërence to HG 14 und HG 19, during regeneration of the absorbent materiat 218, the absorbent material 218 is fixed to SUppOrt structure 219 and travels around member 291 and through ii so that part or portion of the absorbent material 218 remains constantly enclosed within the liquid catchment means enclosure module 11 whilst portion of the body of the absorbent material 18 remains exposed and in contact with surface 11. Motive energy to rotate the absorbent material 218 around members 291 is provided by drive motor 222 which is fixed to gearwheel 224. Gearwheel 224 meshes with gearwheels 226 and 228. Gearwheels 226 and 228 are fixed to rollers 214 and 216 so that 1⁄2hen gearwheel 224 rotates at the direction of arrow 223, causing gearwheel 226 to rotate in the opposite direction shown by arrow 227, thus gearwheel 226 causing gearwheel 228 to rotate at the opposite direction shown by arrow 229, thereby causing portion of the absorbent material 218 which is held in compression force or sandwiched along the lengths of the surfaces of rollers 214 and 216, and to move in between the rollers 214 and 216 at direction of arrow 254 see FIG 14(b). Roller 214 is further joined to a presser-guide toiler 275 whilst roller 216 is further joined to receiver-grooved roller 235. Grooved roller 235 meshes withgrooved side 237 of support structure 219 which is conoccied to the absorbent material 218-The non-grooved side 277 ofsupport structure 219 roratably meets and fits with guide roller 275. Guide roller 275 rotates around the same axis with roller 214 whilst grooved roller 235 rotates around the same axis with roller 216.
Thereto, for the cleaning device 210 to successfully clean surface ii effectively, regeneration or restoration of the absorbent material 218 to its original or restored condition (so that it can be reused to c'ean the surface) has to take place at the same time as the absorbent material 218 continuously or constantly travels in the direction of arrow 255, and comes into contact with the surface 11 collecting contaminant dirt and debris 259 from said surface 11 via cohesion, absorption and adherence causing the absorbent material 218 to accumulate contaminant dirt and debris 259 on and within the absorbent material 218 so that the body of the absorbent material 218 becomes polluted, dirty or degenerated before entering the liquid catchment means enclosure module JI regeneration or restoration. At this particular stage wherein the permeable body and face of'he absorbent material absorbent material 218 carries contaminants dirt and debris 259,and travels in direction of arrow 254, and is about to enter said liquid catchrnent means enclosure module JI, absorbent material 218 is referred to as being in a dirty or degenerated condition. The regeneration of the absorbent material 218 in the second embodiment operates in the same or similar method and process as the regeneration of the absorbent material 18 in the first embodiment.
While the absorbent material 218 is in a degenerated or dirty condition or state, no effective cleaning of surface 11 may take place when the absorbent material 218 is passed over the surface 11, unless the absorbent material 218 is restored to a clean and semi dry condition via cleaning. Cleaning the absorbent material 21$ involves removing contaminant dirt and debris 58 that is previously collected by the absorbent material 218 from cleaning surface II so that the degenerated absorbent material 218 is transformed into a regenerated or restored absorbent material 218 which can then be reused to continuously clean surface 1I.Therefore, as the degenerated or dirty absorbent material 218 carrying contaminant dirt and debris 266 and 259 from surface 11 travels according to direction of arrow 254, it continuously enters the liquid catchnient means enclosure module JI, delivering contaminant dirt and debris 266 and 259 into compartment 1-ti.jhus, once portion ofthe absorbent material 218 enters die liquid eatchrnent means enclosure module.11 and is within compartment I-Il, wherein successive regeneration or restoration cleaning steps are carried out within ii to clean the absorbent material 218. These steps may include one or more orthe combination of(i) removing dirt and debris from the object, (ii) soaking and washing an object (iii) rinsing the object (iv) and drying the object. However when regenerating the absorbent material 218 within the liquid catchment means enclosure module ii, certain steps may be eliminated, added or extended and still attain the equivalent result of a clean dry or semidry absorbent material 218, or so long as the absorbent material 218 can be reused continuously to clean the surface 11 appropriately by thO cleaning head 210. The cleaning steps undertaken within the SI begin when the absorbent material 218 enters compartment HI to encounter scraping means in the form of rotating brush 256 which begins the process of removing impurities contaminant dirt and debris 266 and 259 from the face and permeable body of the absorbent material 218. The rotating brush 256 shears and dislodges loosely herd particles and debris from portion of the passing absorbent material 218 by rubbing off or fiickirg. Dirt and debris 266 and 259 is then evaeuuted from compartment 1-li by suction force 82a in the direction of via drainage port 278 for disposal. Next, as portion of the absorbent material 2t8 now free from dirt and debris travels further into Ji. apex of inner-walls 242 compresses and temporarily alters the shape of the resilient body, thereby removing contaminant liquid and debris before portion of the brushed absorbent material 218 proceeds to enter into compartment Gi. Once portion of the absorbent material 218 is within compartment Gi, liquid applicator 260 discharges or ejects liquid 264 onto face and body of the absorbent material 218. Conduit 261 and conduit 265 are fluidly connected to conduit 286 which delivers liquid 264 into liquid applicator 260 or liquid applicator 262 respectively as governed by the direction of the absorbent material 21f& Thus, there may be a liquid contrOl valve in-between liquid applicator 260 and liquid applicator 262. Conduit 286 is fluidly connected to clean liquid storage tank NI which may either be situated within the chassis of the cleaning device or away and liquid 264 delivered from a clean liquid soUrce away from the cleaning device, eg a water mains source. ThLIs, fluid 264 may be clean fluid such as water; however, fluid 264 can be any other type of fluid.
Discharged. squirted or sprayed liquid 264 flushes, cleanses and soaks into the body of the absorbent material 218 thercby rinsing, dissolving, dilu.ing, loosening and dispersing contaminant particulaes collcctcd from surface Ii, and including mixtures of dirt and wastc liquids 266 and 259 held within the porous body of the absorbent material 218 and sending said dislodged contaminants in a direction away from the permeable body of the absorbent material 218. Waste liquid 266 is then evacuated from compartment CI by suction force 82a via drainage port fluidly connected to conduit 280 for disposal. At this stage, portion of the absorbent material 218 in compartment Cl is soaked wet and waiting to be wrung. As portion of the absorbent material 218 leaves compartment Cl, apex of inner wall 243 compresses and temporarily alters the shape of the resilient body of the absorbent material 218, entering into compartment Fl. Apex of inner wall 243 also helps to further remove waste liquid 266 which is a mixture of liquid 264 and contaminants, debris and dissolved particles (collected from surface II by passing portion of the absorbent material 218) which are prevented from further adhering on or within the body of the absorbent material 218, or otherwise reaching compartment F] -Once the soaked portion of the absorbent material 218 is in compartment Fl, dissolved and diluted mixtures of particles dirt and debris 266 and 259 are now to he removed from the rinsed body of the absorbent material 218. Thus, as portion of the absorbent material 218 progresses further in the direction of arrow 254, through and away fro compartment Fl and into compartment El, wherein between are rollers 214 and 216 located lengthwise along central wall 244 so that portion of the absorbent material 218 becomes sandwiched and gripped in-between the compressing force of the surfaces of rollers 214 and 216, (rotating in the direction of arrow 227 and 229 respectively) moving the sandwiched absorbent material 218 in direction of arrow 255. These combined compressing and pulling action by rollers 214 and 216 temporarily compress portion of the resilient porous body of the absorbent material 218 forcing the spent mixtures ofeontaminant waste liquid 266,259 and dissolved particles therein to be expelled from the permeable body of the absorbent material 218, so that as portion of the absorbent material 218 emerges (whilst regaining shape) from the other side of compartment El (or in basin portion 81) of the rollers 214 and 216 and into compartment El, absorbent material 218 is in a clean dry and or semidry condition. Thusly, the degenerated portion of the absorbent material 218 previously in compartments Ft is now in compartment El having been transformed into a regenerated or restored condition ready to become reused by the cleaiiing head 210 to clean surface It. Once in compartment El, the restored or regenerated absorbent material 218 (now ready to be reused) is in a dry or semid6 condition and travelling in the direction of arrow 254, and about to exit the liquid catchment means enclosure module 31, and regain contact with the cleaning surface 11 in order to perform suitable cleaning on said surface. However, the absorbent material 218 has to continue travelling (in the direction of arrow 254) through compartments Dl and Cl of basin portion 81 which preferably is a mirrored reflection of basin portion At. In some embodiments, the cleaning head 210 may have basin portion Al only, making the absorbent material 218 to travel in one direction only, e.g. in direction of arrow 254 or opposite to direction of arrow 254 only, so as to perform suitable cleaning on surface 11. Thus, with reference to FIG 14 (a,b,c) the regenerated absorbent material 218 which now is in compartment El and encounters apex of inner-wall 245 temporarily altering the shape of the resilient permeable body of the absorbent material 218 before entering into compartment Dl. Meanwhile, any remaining spent liquids and or debris which apex 245 may have scrapped away or forced off from the passing portion of the absorbent material 218 is evacuated ftom compartment El by suction force 82a thru drainage port fluidly connected to conduit 280 for disposal. Portion of the absorbent material 218 then proceeds to enter the following compartment 01 wherein liquid applicator 262 is disabled so as not to soak or drench the clean regenerated dry or seniidryabsorbent material 218 which then proceeds to leave compartment Dl and enters compartment Ci in the same manner (as in preceding compartn-ients) and after being temporarily compressed by apex of inner-wall 247. Any remnants of spent liquids, waste liquid 266 and or debris 259 removed from the permeable body of the absorbent material 218 by apex 247 are evacuated from compartment 01 (by suction force 82a or any other evacuation means) via drainage port 276. As the absorbent material 218 proceeds in the direction of arrow 254, and entering into compartment Cl, rotating brush 257 fixed therein brushes face and body of the absorbent material 218 so as to remove any remaining debris, or dirt particles which may be still clinging on.
Preferably, the rotating brush 257 rotates in the direction opposing that of the passing absorbent material 218 so that any dirt, debris hair and particles which may still be clinging onto the body and or face of the absorbent material 218 are removed and evacuated from compartment Cl before portion of the absorbent material leaves JI in a clean and dry condition and regain contact with surface ii once again, and the cycle continues. From here (compartment Cl), the clean regenerated dry or semidry absorbent material 218 leaves the liquid catehrnent means enclosure module JI to recorni-nence contact with the cleaning surfac 11, and the cycle continues. The same process to regenerate the absorbent material 218 as described above takes place when the absorbent material 218 travels through the liquid catchment means enclosure module 11 in the direction opposite that of directional arrow 254, so that the steps or processes performed in basin portion Al (when absorbent material 218 moves in direction of arrow 254) are successively repeated in basin portion Dl (when the absorbent material 218 moves in direction opposite that of arrow 254), and also, steps or processes performed in basin portion HI (when absorbent material 218 moves in direction of arrow 254) are repeated in basin portion Al (when the absorbent material 218 moves in direction opposite that of arrow 254). Apexes of the inner-waIls 242, 243, 245 and 247 perform the equivalent task of removing spent contaminant waste liquid and debris as well as keeping individual or respective compartments 111, 61, Fl, El, Dl and Cl free from impurities (and or chemicals and gases) contained within said neighbouring compartments. Preferably, all drainage ports 270, 272, 276, 278 are molded and configured to evacuate waste liquids dirt and debris 259, 266, such as from compartments 1-11 and Cl, drainage ports (276, 278) therein are wide enough and configured to suitably maintain an adequate negative prcssufc of suction force 82a within compartments Eli and Ci so that eflèctive evacuation oldirt and debris from the passing body portion of the absorbent material 218 takes place therein.
With reference to FIG. 30 to FIG. 33 of the second preferred embodiment of the present invention the cleaning head 210 may be upgraded on prior art cleaning apparatuses. The cleaning head 210 may be adapted onto prior art domestic cleaning apparatus such as in FtC 36.
With reference to FIG. 30 the cleaiiing head is adapted into a prior art cleaning apparatus. The cleaning head may carry a preceding cleaning region and a following cleaning region. The preceding cleaning region may comprise cleaning components arranged to collect loose particulates and debris from the cleaning surface 11 across cleaning width. The cleaning components of the preceding cleaning region may utilize a scrubbing component. The scrubbing component may be positioned (at the Suction mouth) and in contact with object surface 11. The scrubbing component is an auger-like brush 232 made from brushes, nylon, or any abrasive material and extends along the entire width of the cleaning head and being supported by spindle 233. The scrubbing material 232 supported on a spindle 233 revolving or rotatably fixed atnund slot element 133a (FIG. 30a and FIG. 31b) connected to support member 279 of the cleaning apparatus. Slot element 133b (FIGS 16 -26) pertbrms similar or equivalent operations as slot element l33a.
With reference to FIG 35 the cleaning components of the preceding cleaning region may utilize a vacuuming or suctioning means producing suction force 82a via negative vacuum area 112 sandwiched by an outer lip element and inner lip element forming a cavity or hood 212a (FIG 35e) disposed on the transverse edge of the base ofthe cleaning head 210 of the cleaning device, The hood 212a can be interconnected to disposal conduits via flexible or non-flexible joints to allow the support member 279 to rock from side to side during cleaning operations as well as for the disposal ofdirt and debris collected from the cleaning surface. With reference to FIG 34b and 35b the support member 279 may slant, incline or rotate towards the clockwise direction when moving the cleaning head 210 in a forward direction 101 so that the absorbent material 218 comes into contact with the surface 11, and when the rcvcrse action is done (FIG 34a and 35c), the support member 279 slants towards the amiclockwise direction as the cleaning head 210 moves along a surface 11 in the direction according to arrow 110. One advantage of this mechanism allows the cleaning head of the cleaning device disclosed herein this patent application to simultaneously perform the task of vacuuming a surface and wet wiping the surface simultaneously. When loose dirt and debris 266, 259 is being collected from the surface 11. it is not pushed away since the absorbent material 218 is lifted, and on the other hand, the absorbent material 218 on the opposite side makes contact with the cleaning surface 11 (which hasjust been vacuumed) and wet cleans it; and the reverse action happens when the cleaning hcad 210 moves at the opposite direction, and the cycle continues. One advantage of this combination of tasks (simultaneous vacuuming and continuous wet-clean wiping) is that immense time and effort is saved for the user who would otherwise have two or more separate manual (bucket and mop) cleaning tasks to follow the conventional vacuuming operation on the cleaning surface 11.The means to rock the support member 279 from side to side depending on the direction 110,101 of the cleaning head 210 can be controlled by a number of ways (automatic or mechanical) such as through electromagnetic diodes. eiecironic switches which are hiterconnected via automatic directional motion sensors on wheels in frictional contacj with surface 11, optical (infra-red) surface-direction sensors (c.gon au optical mouse and or inoiise-whee), interlocking-spur wheel reciprocation means etc or via mechanical direction means such as gearwheel coupling which relay precise motion interpretation of relative surface direction 110 or 101 of the cleaning head 210. The hood 212a may have retracting means (FIG 35a and FIG 21), from the surface 11 when not in use or when the user of the cleaning device is vacuuming the surface only. Dashed lines on FIG 34 depict the absorbent material 218 in the resting or retracted position. Dashed lines on FIG 20 and FIG 21 show the absorbent material supported by support structure 279 in a retracted position and the reverse with absorbent material 218 in contact with surface 11. Thusly, the cleaning head 210 can perform wet cleaning tasks only. FIG 34c depicts an example of the cleaning head with wheel 104 and without the scrubbing element 132. The scrubbing material 132 also generates a shearing force as it moves with respect to the cleaning surface 1! and the force helps to break adhesion and other bonds between contaminants and the cleaning surface 11 before suction 82a collects the loosened dirt.
In addition, the scrubbing material 132 may have one or more passive elements such as a scraper (not shown) attachment on lace of cleaning head 210 and in contact with surface 11 and configured to agitate contaminants stuck on the cleaning suahce 11 when the cleaning head 210 is moved across, to and fin the cleaning surface 11 during cleaning operation.
With reference to P16.16 and FIG. 19 surface-liquid applicator 136a is configured to simultaneously apply cleaning fluid 137 onto the cleaning surface 11 and scrubbing material 132 or configured to apply or sprays cleaning fluid 137 onto the scrubbing material 132 which in turn smears and agitates applied cleaning fluid 137 to mix it with contaminants on surface 11, emulsifying, dissolving or otherwise chemically reacting with the contaminants. The surface-liquid applicator 136a is arranged symmetrically outward from centre along the entire width of the cleaning head 210. Surface-liquid applicator 136a may also be utilized for the purpose of rinsing the surfacell before the spent liquid mixture is collected by the absorbent material 218.
The following cleaning region may utilize cleaning components configured to wipe or dry the cleaning surlèce 11. The following cleaning region may also carry a surface-liquid applicator 138a arranged to apply a cleaning fluid 139 onto the surface 11.Cleaning fluid 137 and cleaning fluid 139 may he drawn from storage tank and administered with soap as required. Thus when necessary, plain or pure water can he used for rinsing in the following cleaning region and also in other processes in other parts within the cleaning head 210, suchas in the liquid catchment means enclosure module Ji.
Cleaning fluid 137 may be pumped from source storage tank or delivered to the outlet of surface-liquid applicator 138a and or to outlet of surface-liquid applicator 136a via gravity once a valve liquid release mechanism (not shown) is actuated, however, a pump may be utilized instead.
Surface-liquid applicator 138a may also be used for the purpose of rinsing the surfacell before the spent liquid mixture is collected by the absorbent material 218.
Referring now to FIG. 42 to FIG. 53 of the third preferred embodiment of the present invention the annular belt or ring shaped absorbent material 218 in the preceding embodiment can be modified further by manipulating the edges of the absorbent material so that the preceding embodiment changes slightly from the third embodiment by slightly changing the design of the configuration whilst maintaining the working of the cleaning device in regard to cleaning an extended surface according to the spirit of this invention disclosure. The configuration of the absorbent material 318 in this third embodiment is similar or resembles a caterpillar digger's track wheels or military tank's motive track mechanism.
With reference to FIG 42, the absorbent material 318 is attached to support structure 319 and rotate by guide wheels 391 which are held in place by member 379. Support structure 319 is rotatably fixed to member 379 for continuous rotation of the absorbent material 318 is achieved at either clockwise or anticlockwise direction. Grooved roller 314 and roJler 316 provide the energy to rotate the absorbent material 318 attached to the support structure 319. Thus the support structure 319 may rotate revolve eccentricaiiy whiist supporting the absorbent material entering arid leaving the third embodiment's liquid catchment means enclosure module J3 for regeneration. The support structure according to FIG.42 to FIG. 53 is annular or ring shaped structure 319 whereto the absorbent material 318 is attached.
With reference to FIG 44, FIG 45 and FIG 47 the absorbent material 318 is in contact with a surface 11 and supported thereupon by one or more wheels 104. However, in some embodiments, the cleaning head 310 may be supported on surface 11 with wheels 104 (FIG 47; however, wheels may not be necessary as in FIG 44 and FIG 48). Preferably, the absorbent material 318 also touches or lies in contact with cleaning surface 11, however, the absorbent material 318 may be retractable or can he raised away from the cleaning surface 11 via member 379 whilst the rest of the cleaning head 310 remains supported on the cleaning surface 11. With reference to FIG 42, FIG 43 and FIG 46, during regeneration of the absorbent material 318, the absorbent material 318 is fixed to support structure 319 and travels around member 391 and through J3 so that part or portion of the absorbent material 318 remains constantly enclosed within the liquid catchment means enclosure module J3 whilst portion of the body of the absorbent material 318 (on the side opposite support structure 319) remains exposed and in contact with surface 11. Motive energy is delivered by electric conduit 394a to drive the absorbent material 318 according to the arrangement around members 391 with energy provided by drive motor 322 which is fixed to pulley-wheel 393. Pulley 393 is connected to gearsvheels 328 and 326. Gearwheels 326 and 328 are fixed to rollers 314 and 316 so that when pulley 393 rotates at the direction of arrow 323, causing gearwheel 328 to rotate in the direction shown by arrow 327, thus gearwheel 328 causing gearwheel 326 to rotate at the opposite direction shown by arrow 329, thereby causing portion of the absorbent material 318 which is held in compression force or sandwiched along the lengths of' the surfaces of grooved roller 314 and 316, and to move in between the rollers 314 and 316 at direction oarrow 354. Grooved roller 314 is a presser-guide roller whilst roller 316 compresses portion of the passing absorbent material 318 continuously. Grooved roller 314 meshes with grooved side 337 of support structure 319 which further connected on one face to the absorbent material 318. Grooved roller 314 rotates around the same axis with gearwheel 326 whilst roller 316 rotates around the same axis with gearwheel 328.
Thereto, for the cleaning device 310 to successfully clean surface 11 effectively, regeneration or restoration of the absorbent material 318 to its original or restored condition (so that it can be reused to clean the surface) has to take place at the same time as the absorbent material 318 continuously or constantly travels in the direction of arrow 355, and comes into contact with the surface 11 collecting contaminant dirt and debris from said surface 11 via cohesion, absorption and adherence causing the absorbent material 318 to accumulate contaminant dirt and debris on and within the absorbent material 318 so that the body of the absorbent material becomes polluted, dirty or degenerated before entering the liquid catchment means enclosure module J3 regeneration or restoration. At this particular stage wherein the permeable body and face of the absorbent material 318 carries contaminants dirt and debris and travels in direction of arrow 354, and is about to enter said liquid catchment means enclosure module.13, absorbent material 318 is referred to as being in a dirty or degenerated condition. The regeneration of the absorbent material 318 in the third embodiment operates in the same or similar method and process as the regeneration of the absorbent material 18 in the first embodiment.
While the absorbent material 318 is in a degenerated or dirty condition or state, no effective cleaning olsurtace ii may take place when the absorbent material 318 is passed over the surface 11. unless the absorbent material is restored to a clean and semi dry condition via cleaning. Cleaning the absorbent material 318 involves removing contaminant dirt and debris that is previously collected by the absorbent material from cleaning surface 11 so that the degenerated absorbent material 318 is transformed into a regenerated or restored absorbent material which can then be reused to continuously clean surface 1l.Therefore, as the degenerated or dirty absorbent material 318 carrying contaminant dirt and debris from surface 11 travels according to direction of arrow 354, it continuously enters the liquid catchment means enclosure module.J3, delivering contaminant dirt and debris into a compartment in J3. Thus, once portion of the absorbent material 318 enters the liquid catchrnent means enclosure module.13 and is within the first compartment, successive regeneration or restoration cleaning steps are carried out within J3 to clean the absorbent material 318. These steps may include one or more or the combination of (i) removing dirt and debris from the object, (ii) soaking and washing an object (iii) rinsing the object (iv) and drying the object. However when regenerating the absorbent material 318 witbin the liquid catchment means enclosure module i3, certain steps may be eliminated, added or extended and still attain the equivalent result ofa clean dry or semidry absorbent material 318, or so long as the absorbent material 318 can be reused continuously to clean the surface ii appropriately by the cleaning head 310. The cleaning steps undertaken within the.13 begin when the absorbent material encountering a scraping means in the form of rotating brush 356 which begins the process of removing impurities contaminant dirt and debris from the face and permeable body of the absorbent material 318. The rotating brush 356 shears and dislodges loosely held particles and debris from portion of the passing absorbent material 318 by rubbing off or flicking. Dirt and debris is then evacuated from the first compartment by suction force or other evacuation means in the direction of via drainage port 378 for disposal. Next, liquid applicator 360 discharges or ejects rinsing liquid 364 onto face and body of the absorbent material 318. Liquid applicator 360 and liquid applicator 362 are fluidly connected to conduit 386 which delivers liquid 364 into liquid applicator 360 or liquid applicator 362 respectively as governed by the direction of the absorbent matcrial 318. Thus, there may b a liquid control valve in-between liquid applicator 360 and liquid applicator 362. Conjpit 386 is flu idly connected to clean liquid storage tank M which may either be situated within the chassis of the cleaning device or away and liquid 364 delivered ftom a clean liquid source away froii the cleaning device, e.g a water mains source. Thus, fluid 364 may be clean fluid such as water; however, fluid 364 can be any other type of fluid.
Discharged, squirted or sprayed liquid 364 flushes, cleanses and soaks into the body of the absorbent material 318 thereby rinsing, dissolving, diluting, loosening and dispersing contaminant particulates collected from surface 11. and including mixtures of dirt and waste liquids held within the porous body of the absorbent material and sending said dislodged contaminants in a direction away from the permeable body of' the absorbent material. Waste liquid 366 is then evacuated from the compartment by pumping means or via suction force $2a via drainage port fluidly connected to conduit 380 for disposal. At this stage, portion of the absorbent material 318 in the compartment is soaked wet and waiting to be wrung. As portion of the absorbent material 318 leaves the compartment and ingested in-between the force of rollers 314 and 316 located lengthwise along central wall 344 so that portion of the absorbent material 318 becomes sandwiched and gripped in-between the compressing force of the surfaces of rollers 314 and 316, moving the sandwiched absorbent material 318 in direction of anow 355. These combined compressing and pulling action by rollers 314 and 316 temporarily compress portion oithc resilient porous body f the absorbent material 318 forcing the spent mixtures of contaminant spent waste liqLlid and dissolved particles therein to be expelled from the permeable body of the absorbent material 318, so that as portion of the absorbent material 318 emerges (whilst regaining shape) from the other side of the rollers 314 and 316, absorbent material 318 is in a clean dry and or semidry condition. Thusly, the degenerated portion of the absorbent material 318 previously in the first compartment (of liquid applicator 360) is now in the second compartment (of muted liquid applicator 362) having been transformed into a regenerated or restored clean condition ready to become reused by the cleaning head 310 to clean surface 11 once it re-emerges from J3 at direction orarrow 355 to regain contact with the cleaning surface 11 and the cycle continues. Portion of the absorbent material 318 then proceeds to enter the following compartment of liquid applicator 362 which is muted or disabled so as not to soak or drench the clean regenerated dry or semidry absorbent material 318 which then proceeds to leave the compartment before portion of the absorbent material leaves J3 in a clean and dry condition and regains contact with surface 11 once again, and the cycle continues. The same process to regenerate the absorbent material 318 as described above takes place when the absorbent material 318 travels through the liquid catchment means enclosure module J3 in the direction opposite that oldirectional arrow 354, so that the steps or processes performed in the first compartment (when absorbent material moves in direction of arrow 354) are successively repeated in the second compartment (when the absorbent material moves in direction opposite that of arrow 354), and also, steps or processes performed in the first compartment (when absorbent material 318 moves in direction of arrow 354) are repeated in the second compartment (when the absorbent material moves in direction opposite that of arrow 354). Preferably, all drainage ports 370, 372, 376, 378 are molded and configured to evacuate waste liquids dirt and debris from the first and second compartments and are wide enough and configured to suitably maintain an adequate negative pressure of suction force 82a or pumping force or whichever most suitable to evacuate dirt from the passing body of the absorbent material 318 taking place therein.
With reference to FIG. 47 to FIG. 49 of the third preferred embodiment of the present invention the cleaning head 310 may be upgraded on prior art cleaning apparatuses.
With reference to FIG. 44 and FIG 45 the cleaning head is adapted into a prior art cleaning apparatus.
The cleaning head may carry a preceding cleaning region and a following cleaning region. The preceding cleaning region Xl may cornprise.eteaning components arranged to wet-wipe the cleaning surface II across cleaning width. The cleaning components of the following cleaning region X2 may utilize a scrubbing component, Cleaning region Xl and cleaning region X2 are separated by a dividing wall X3. Dividing wall X3 prevents the loss of suction or negative pressure 112 from being lost so that adequate collection of dirt and debris takes place within cleaning region X2. The scrubbing component in X2 may be positioned (at the suction mouth) and in contact with object surface 11. The scrubbing component is an auger-like brush 332 made from brushes, nylon, or any abrasive material and extends along the entire width of the cleaning head 310 and being supported by spindle 333. The scrubbing material 332 is supported and rotates on axis of spindle 333.However the preceding and following cleaning steps may change for example when the user prefers to wet clean the surface without vacuuming or scrubbing or vice-versa.
With reference to FIG 43 to FIG 48 the cleaning components of the preceding cleaning region may utilize a vacuuming or succioning means producing suctio. force 82a via negative vacuum area 112 sandwiched by an outer lip element and inneklip element forming a cavity or hood disposed on the transverse edge of the base of the cleaning head 310 of' the cleaning device. The hood can be interconnected to waste disposal conduits via flexible or non-flexible joints for the disposal of dirt and debris collected from the cleaning surface II. With reference to FIG 42. FIG 45 and FiG 46 the support member 379 may slant, sctcsor_l?fi expand or contract, retract inward of the hood or extend so that the absorbent material 318 contacts surface 11 during a cleaning operation. Similarly to the second embodiment of th is patent disclosure, the absorbent material 318 in the third embodiment may operate in the same manner as 218 in the second embodiment such that when the cleaning head 310 is moved across the surface in the forward or 101 direction, the absorbent material 318 is temporarily lifted from the cleaning surface 11; and when the cleaning head 310 is moved in the backward or 110 direction, the absorbent material 318 makes contact with the cleaning surface II and the cycle continues, One advantage of this mechanism allows the cleaning head 310 of the cleaning device disclosed herein this patent application to simultaneously perform the task of vacuuming a surface and wet wiping the surface simultaneously. Furthermoic, when loose dirt and debris is being collected from the surface 11 when moving MO at direction 101, dirt and debris is not pushed away since the absorbent material 318 is lifted to allow the following cleaning region with the force of vacuum area 112 to collect the dirt and debris first before the wet-cleaning operation. The reverse action happens when the cleaning head 310 moves at the opposite direction, and the cycle continues.
One advantage of this combination of tasks (simultaneous vacuuming and continuous we/-clean wiping) is that immense time and effort is saved for the user who would otherwise have two or more separate manual (bucket and mop) cleaning tasks to follow the conventional vacuuming operation on the cleaning surface 11. The means to extend and retract the support member 379 from side to side depending on the direction 110,101 of the cleaning head 310 can be controlled by a number of ways (automatic or mechanical) such as through electromagnetic diodes, electronic switches which are interconnected via automatic directional motion sensors on wheels in frictional contact with surface Ii. optical (infra-red) surface-direction sensors (e.g on an optical mouse and or mouse-wheel) interlocking-spur wheel reciprocation means etc or via mechanical direction means such as gearwheel coupiing which relay precise motion interpretation of relative surface direction 110 or 101 of the cleaning head 310. l'lic hood may have retracting means from the surface 11 when not iii use or when the user of the cleaning device is vacuuming the surface only. Thusly, the cleaning head 310 can perform wet cleaning tasks only. FIG 34c depicts an example of the cleaning head with wheel 104 and without the scrubbing material 332. The scrubbing material 332 also generates a shearing force as it moves with respect to the cleaning surface 11 and the force helps to break adhesion and oilier bonds between contaminants and the cleaning surface 11 before suction 82a collects the loosened dirt.
In add ition, the scrubbing material 332 may have one or more passive elements such as a scraper (not shown) attachment on face of cleaning head 310 and in contact with surface 11 and configured to agitate contaminants stuck on the cleaning surface 11 when the cleaning head 310 is moved across, to and fro the cleaning surface 11 during cleaning operation.
Cleaning head 310 may also carry a surface-liquid applicator (not shown) arranged to apply a cleaning fluid or a rinsing fluid onto the surface l1.Cleaning fluid may be drawn from storage tank and administered with soap as if required. Thus, when necessary, plain or pure water can be used for rinsing the surface prior to passing the absoent material 318. Cleaning and rinsing fluid may be pumped from source storage tank NI or delivered to the outlet of surface-liquid applicator (not shown) and or to outlet of surthee-Iiquhj applicator via gravity once a valve liquid release mechanism (not shown) is actuated, however, a pump may be utilized instead. Surface-liquid applicator (not shown) may also be used for the purpose of rinsing the surfacell before the spent liquid mixture is collected by the absorbent material 318.
Referring now to FIG. 54 to FIG. 63 of the fourth embodiment of the present invention the annular belt or ring shaped absorbent material 318 in the preceding embodiment can be modified further by removing the support structure 319 or similarly, by omitting support structure 19 (see FIG 1-4) from the first embodiment of this patent disclosure. The configuration of the absorbent material 418 in this fourth embodiment is similar or equivalent to the arrangement of the first embodiment of this patent disclosure even though the elements most notably the rollers 414 and 416 are internally modified into liquid receptacles and are much larger in size externally yet still performing the required action and task in the suitable and desired outcome.
With relèrencc to FIG 54, the absorbent majerial 418 is a firmer yet still resilient absorbent body which is guided around the cleaning device 410 via moulded channels contours tbrmed with various contours readied for the configuration of the absorbent material 418.Guide rollers 499 hold the absorbent niaterial 418 in place at the alt lift region extending rearwards throughout periphery whilst the absorbent material 418 which is ring-shaped in configuration is clamped tightly by the closeness of rollers 414 and 416 in the central region. Roller 414 and 416 provide the energy to rotate the absorbent material 418. Absorbent material 418 may rotate revolve eccentrically whilst entering and leaving the fourth embodiment's liquid catchment means enclosure module J4 for regeneration.
With reference to FIG 63 the absorbent material 418 is in contact with a surface 11 and supported thereupon by user as in FIG 54. Preferably, the absorbent material 418 also touches or lies in contact with cleaning surface 11, however, the absorbent material 418 may be retractable or can be raised away from the cleaning surlèce Ii whilst the rest of the cleaning head 410 remains supported on the cleaning surface 11. With reference to FIG 54, FIG 55 and FIG 57. during regeneration of the absorbent material 418, the absorbent material 418 rotates around and is guided by keepers 499 and through.14 so that part or portion of the absorbent materki 418 remains constantly enclosed within the liquid catchojent means enclosure niodule44 whilst portion of the body of the absorbent material 418 remains exposed and in contact with surface 11. Motive energy is delivered by electric conduit a motor which drives the absorbent material 418 according to the arrangement around keepers 499. The motor's gearwheel is meshed with gearwheel 428 and gearwheel 426 meshes with gearwheel 428.
Gearwheeis 426 and 428 are fixed to rollers 414 and 416 respectively so that when roller 428 rotates at one direction, roller 426 rotates at the directly opposite direction thereby causing portion of the absorbent material 418 which is held in compression force or sandwiched along the lengths of the surfaces of roller 414 and 416, and to move in between rollers 414 and 416 at direction of arrow 454 (see FIG 57). Roller 414 and 416 compresses portion of the passing absorbent material 418 continuously regardless of direction 454 or reverse of said direction. Roller 414 rotates around the same axis with gearwheel 426 whilst roller 416 rotates around the same axis with gearwheel 428.
Thereto, for the cleaning device 410 to successfully clean surface 11 effectively, regeneration or restoration of the absorbent material 418 to its original or nstored condition (so that it can be reused to clean the surface) has to take place at the sanie time as the absorbent material 418 continuously or constantly travels in the direction of arrow 454, and comes into contact with the surface ii collecting contaminant dirt and debris from said surface 11 via cohesion, absorption arid adherence causing the absorbent material 418 to accumulate contaminant dirt and debris on and within the absorbent material 418 so that the bodyofthe absorbent material becomes polluted, dirty or degenerated before entering the liquid catchment means enclosure module J4 regeneration or restoration. At this particular stage wherein the permeable body and face of the absorbent material 418 carries contaminants dirt and debris and travels in direction of arrow 454, and is about to enter said liquid catchment means enclosure module J4, absorbent material 418 is referred to as being in a dirty or degenerated condition. The regeneration of the absorbent material 318 in the third embodiment operates in the same or similar method and process as the regeneration of the absorbent material 218 in the second embodiment.
While the absorbent material 418 is in a degenerated or dirty condition or state, rio effective cleaning of surface 11 may take place when the absorbent material 418 is passed over the surface II, unless the absorbent material is restored to a clean and semi dry condition via cleaning. Cleaning the absorbent material 418 involves removing contaminaijs dirt and debris that is prevously collected by the absorbent material from cleaning surlhee 11 so that the degenerated absorbent material 418 is transformed into a regenerated or restored absorbent material which can then be reused to Continuously clean surface II.Iherefbre, as the degenerated or dirty absorbent material 418 carrying contaminant dirt and debris from surface TI travels according to direction of arrow 454, it continuously enters the liquid catchment means enclosure module J4, delivering contaminant dirt and debris into a conlpartment in J4. Thus, once portion of the absorbent material 418 enters the liquid catebment means enclosure module J4 and is within the first compartment, successive regeneration or restoration cleaning steps are carried out within J4 to clean the absorbent material 418. These steps may include one or more or the combination of (I) removing dirt and debris from the object, (ii) soaking and washing an object (iii) rinsing the object (iv) and drying the object. However when regenerating the absorbent material 418 within the liquid catchrnent means enclosure module.14, certain steps may be eliminated added or extended and still attain the equivalent result of a clean dry or semidry absorbent material 418, or so long as the absorbent material 418 can be reused continuously to clean the surlhce 11 appropateJy by the cleaning device 410. The cleaning steps undertaken within the.14 begin when the absorbent material encountering a scraping means in the form of rotating brush which begins the process of removing impurities contaminant dirt and debris from the face and permeable body of the absorbent material 418. The rotating brush shears and dislodges loosely held particles and debris from portion of the passing absorbent material 418 by rubbing off or flicking. Dirt and debris is then evacuated from the first compartment by suction force or other evacuation means in the direction of via drainage port for disposaf. Next, a liquid applicator discharges or ejects rinsing liquid onto face and body of the absorbent material. The liquid applicator is fluidly connected to a conduit which delivers clean liquid into liquid applicator on the first compartment or liquid applicator in the second compartment respectively as governed by the direction of the absorbent material 418. Thus, there may he liquid control valve in-between said liquid applicators. The clean liquid conduit is fluidly Connected to clean liquid storage tank (M) which may either be situated within the chassis ofthe cleaning device 410 or away so that clean liquid is delivered from a clean liquid source away from the cicaning device, e.g a water mains source.
Diseljared squirted or sprayed clean liquid flushes, cleanses and soaks into the body of the absorbent material 418 thereby rinsing, dissolving, diluting, loosening and dispersing contaminant particulates collected from surface 11, and including mixtures of dirt and waste liquids held within the porous body of the absorbent material and sending said dislodged contaminants in a direction away from the permeable body of the absorbent material. Waste liquid is then evacuated from the compartment by pumping means or via suction force 82a (or negative pressure 112) via drainage port fluidly connected to conduit tbr disposal. At this stage, portion of the absorbent material 418 in the compartment is soaked wet and waiting to be wrung. As portion of the absorbent material 418 leaves the compartment and ingested in-between the force of rollers 414 and 416 located lengthwise along central wall 444 (which runs along the fore 101, aft 110 axis within 14) so that portion of the absorbent material 418 becomes sandwiched and gripped in-between the compressing force of the surthees of rollers 414 and 416, moving the sandwiched absorbent material 418 in direction of arrow 454. These combined compressing and pulling action by rollers 414 and 416 temporarily compress portion of the resilient porous body of the absorbent material 418 forcing the spent mixtures of contaminant spent waste liquid and dissolved particles therein to be expelled from the permeable body of the absorbent material 418, so that as portion of the absorbent material emerges (whilst regaining shape) from the other side of the ollers 414 and 416, absorbent material 418 is in a clean dry and or semidry condition. Thusly, the degenerated portion of the absorbent material 418 previously in the first compartment (of liquid applicator) is now in the second compartment (ofmuted liquid applicator) having been transformed into a regenerated or restored clean condition ready to become reused by the cleaning device 410 to clean surface 11 once it re-emerges from 34 at direction of arrow 454 to regain contact with the cleaning surface 11 and the cycle continues. Portion of the absorbent material 448 then proceeds to enter the following compartment of the second liquid applicator which is muted or disabled so as not to soak or drench the clean regenerated dry or semidry absorbent material which then proceeds to leave the second compartment before portion of the absorbent material leaves J4 in a clean and dry condition and regains contact with surface 11 once again, and the cycle continues. The same process to regenerate the absorbent material 418 as described above takes place when the absorbent material 418 travels through the liquid catchment means enclosure module J4 in the direction Opposite that u1dircctiona( arrow 454, so that the steps or processes perlhrmed in the first compartment (when absorbent material moves in direction of arro' 454) are successively repealed in thc second compartment (when the absorbent material moves in direction opposite that ofarrow 454). and also, steps or processes performed in the first compartnlent (when absorbent material 418 moves in direction of arrow 454) are repeated in the second compartment (when the absorbent material moves in direction Opposite that of arrow 454).
Preferably, all drainage ports are moulded and configured to evacuate waste liquids dirt and debris from the first and second compartments and are wide enough and configured to suitably maintain an adequate negative pressure of suction force 82a (negative pressure 112) or pumping force or whichever most suitable to evacuate dirt from the passing body of the absorbent material 418 caking place therein.
With reference to FIG. 56 and FIG. 57 of the fourth preferred embodiment of the present invention the cleaning device 410 may be scaled up to a cleaning device 410 the size of an iron-box or can be scaled down to a cleaning device 410 the size of a computer mouse. Therefore the cleaning device may carry a preceding cleaning region and a following cleaning region or simply have a singie cleaning region dominated by the absorbent ncterial 418. in the present examples, there is provided a sponge-like scrubbing component The sponge-like scrubbing component is supported and rotates on axis of roller 416. However the preceding and following cleaning steps may change for example when the user prefers to wipe the surface without scrubbing or vice_versa.
With reference to FIG 55, FIG 62 and FIG 63 a retractable mounted support for the absorbent material 418 on the chassis of' the cleaning device 410 has a hinge 498 and is movable between an extended position and a retracted position and has a retracting mechanism for moving the absorbent material between the extended and retracted positions during a cleaning operation. Similarly to the third embodiment ofthis patent disclosure, the absorbent material 418 in the fourth embodiment may operate in the same marine,-as 218 in the second embodiment and 18 in the first embodiment. One advantage of this mechanism allows the cleaning device 410 disclosed herein this patent application to simultaneously perform the task of scrubbing and wet wiping the surface simultaneously or by passing the cleaning device over a dirty surface once. One advantage of this combination of tasks (simultaneous scrubbing and lion-stop wet-clean wiping) is that vast amounts of time and effort is saved for the user who would otherwise have two or more separate manual (bucket and mop) cleaning tasLs to follow conventional surface scrubbing.
A
FIG 62-63 depicts an example of the cleaning device 410 with retractable mounted support in different positions; the firmness of the flexible absorbcnt material 418 allows it to spring away from the surface 11 when the retractable mounted support is lifted and vice-versa.
FIG 63, FIG 63a, FIG 63b, FIG 63e shows the external configuration of the cleaning device 410 showing the flexible action of the hinging mechanism of 498 allowing the encountering of different surface contours and the rcaction of the cleaning device to concave (63a) and convex (63b) surfaces; a major advantage of this adaptability is that the cleaning device can be able to clean surfaces of different contours or stepped surfaces without leaving untouched' portions ot' the surface being cleaned. For example, vehicle surfaces where bumpers meet with the exterior body of the vehicle or under licence plates, on car roof and body edges, and on bonnet valley-contours. The sponge-like scrubbing component also generates a shearing force as it moves with respect to the cleaning surface 11 and the force helps to break adhesion and other bondn between contaminants and the cleaning surface 11. belbre suction 82a collects the jnosened dirt. In addition, the sponge-like scrubbing component may have one or Inure passive elements such as a scraper (not shown) attachment on face of cleaning device 410 and in contact with surface]! and configured to agitate contaminants stuck on the cleaning surface 11 when the cleaning device 410 is moved across, to and fro the cleaning surface 11 during cleaning operation.
Cleaning device 410 may also carry a surface-liquid applicator (shown proximate to surface on FIG 63) arranged to apply a cleaning fluid or a rinsing fluid onto the absorbent material 418 or on the surface 11. Cleaning fluid may be drawn from storage tank and administered with soap as ifrequired.
Thus, when necessary, plain or pure water can be used for rinsing the surface prior to passing the absorbent material 418. Cleaning and rinsing fluid may be pumped from source storage tank (M) or delivered to the outlet of surface-liquid applicator and or to outlet of surface-liquid applicator via gravity once a valve liquid release mechanism is actuated, however, a pump may be utilized instead.
Surface-liquid applicators may also be used for the purpose of indirectly rinsing the surfacel I before the spent liquid mixture is collected by the absorbent material 418.
Referring now to FiG. 64 to FIG. 66 of thelifih embodiment oldie present invention the annular ring shaped absorbent material 418 in the preceding embodiment can be modified further by rearranging the absorbent material 518 so that the method in which the surface 11 is cleaned is different from all previous descriptions for the absorbent material 518 in this example is permanently fixed yet still adequately performing the task of cleaning a surface 11 whilst being continuously regenerated or restored without user intervention. However, the absorbent material 518 may be configured to become regenerated in much the same way as described above, but with the roles of the same components reversed; that is, the liquid catchment means enclosure module J5 is now a moveable carriage that is configured to follow a fixed track so as to trail a permanently fixed or stationary absorbent material 518, for regeneration or restoration. Therefore instead of the passing absorbent material 518 been led into a stationary liquid catchment means enclosure module (e.g JI or 14) as it is described above in the preferred and other embodiments ofthis patent disclosure, the liquid catebment means enclosure module iS is movable and follows the absorbent material 518 to and fro (at direction of 101 and 110 and vice-versa) fbr regeneration during a cleaning operation on cleaning surface 11. Therefore a main difference with the configuration of the absorbent material 418 in the preceding embodiment with this example of the fifth embodiment is that with the fourth embodiment, the absorbent material 418 moves or revolves around the cleaning device and through the J4 whilst with the fifth embodiment, the absorbent material 518 is permanently fixed while J5 moves along by revolving, rotating or to and fro along the body of the absorbent material 518 to perform the crucial task of regeneration on the absorbent material 518 according to the spirit of this patent disclosure.
With reference to FIG 64 and FEC 66, there is provided an inflexible and stationary support structure 519 having fixed onto it the absorbent material 518 which is on contact with the cleaning surface 11.
The absorbent material 518 is a block shaped body which is firmly fixed onto support structure 519 also fixed on the cleaning head 510 attached to a handle, so that regeneration of the absorbent material 518 which is in constant contact with the surface 11 is carried out without lifting the cleaning head 510 from the cleaning surface 11 during a cleaning operation. The device generally includes a handle, connected to a housing ot' the cleaning device 510 which includes the absorbent material 518, support structure 519, waste liquid tank IC and waste uIquid tank NI, a tracked rack and pinion assembly which is rotatabiy connected to.15 and includes pinion gearwheel 526 and a fixed rack gear 528 on at least one side of the cleaning head 510, means to power gearwheel 524 so that the carriage of J5 is able to move to (101) and fro (110) along the rack and pinion assembly so that a roller 514 (rotatably fixed on J5 and pressing on absorbent material 518) is driven to and fro along the length of the support structure 519. Guide rollers 599 hold the rack and pinion assembly in place accordingly during use.
The absorbent material 518 is clamped tightly (against the absorbent material 518 and rigid support structure 519) along the portion-region where length of roller 514 extends. Roller 514 is rotatably connected to at least one frame member 598 wherein this embodiment, a pair of frame member 598 is provided, Frame members 598 hold the entire rack and pinion and all liquid catchnient means enclosure module J5's components together. Immovable absorbent material 518 enters and exits the moving liquid catchment means enclosure module J5 in a to and fro continuous mechanism so that continuous and uninterrupted regeneration or restoration of the absorbent material 518 in contact with dirty surface Ii is constantly regenerated without interruption or any user intervention during the user's domestic or industrial cleaning task, in this example. the absorbent material 518 is squarely or block shaped, however, the absorbent materThl 518 may he configured in any other shape such as rectangular, triangular, circular, a combination of shapes such as rectangle and circular, elliptical or any other shape conceivable. The absorbent material 518 may also include more than one texture on it such as a scraping or scouring portion or spaced strips of scouring material interwoven or vulcanised adjacent to the liquid soaking absorbent material 518. It may also be possible for the absorbent material to be fixed onto the support structure 519 via easy-screws or other means for example Velcro.
With reference to FIG 65a the absorbent material 518 is in contact with a surface Ii and supported thereupon via a handle by uset-O ot shown)Jn this illustration, the frame 598 has been omitted to show how the carriage oIlS receives liquid in the form oil drop shown and including the curvature of the compression force exerted on the flexible absorbent material 518 which is what causes the spent liquid to be forced out of the body of the absorbent material 518 as the cleaning device 510 is used by a user to clean the surface 11.
During operation, as the carriage of.15 moves from side to side according to the length of rack gears 526, the bottom ofJ5 may come into contact with the surface; therefore to avoid damnagng the floor or any other surface 11, there may be a rolling element 104 or wheels such as arbitrary rollers placed underneath the carriage of J5. Also, a brushing or scraping element may be positioned thereunder so that with user actuation, the scraper may be utilized to for example to scrape stubborn dirt from a surface, remove chewing gum or hardened liquids. The rollers under J5 also ensure that the cleaning device 510 works independently without interfering with the sideways or to and fro diiection at which the user steers the cleaning device when pulling and pushing to the forward and backward motion as is commonly done when using any prior art floor cleaning apparatuses. Action of a brush and or scraper underneath J5 may also help the user to keep their domestic or industrial surfaces cleaner and in a more convenient and quicker way, thereby saving strenuous unnecessary cleaning hardships for the user of the cleaning device disclosed herein.
With reference to FiG 64 to FiG 66, liquid catchment means enclosure module J5 moves through absorbent material 518 so that part or portion of the absorbent material 518 remains constantly enclosed within the liquid catchmern means enclosure moduleJ5 whilst portion of the body of the absorbent material 518 remains exposed and in contact with surface ii. Motive energy is delivered by electric conduit to a motor which drives gearwheel 524 according to the arrangement. The motor's gearwheel 524 is meshed with flOfl gearwheel 526 which meshes with rack gear 528. The motor's gearwheel can also be configured as pinion gearwheel 526. When gearwheel 526 rotates at one direction such as clockwise 529, it moves the carriage J5 at the direction of arrow 110. When gearwheel 526 rotates at an anti-cloekv15 direction it moves the carriage J5 at the direction according to arrow 101. Roller 514 is free rolling according to the stresses. During operation roller 514 rotates in a ciockwise direction when carriage J5 is moving at the direction according to arrow 101 and vice-versa when carriage J5 moves at direction according to arrow 110. Roller 514 compresses portion of' the passing absorbent material 518 continuously regardless of intermittent direction 101 or 110 moved. Since the flexible absorbent material 518 is sandwiched along the length of (be siirf1cc of roller 514 and firmly against support structure 519, any liquid held within the absorbent material's body is forced away every time the carriage.35 moves from side (101) to side (110) in a continuously frequency as best equired. When the amount of contaminant or liquid is much on the surthce 11, the frequency 115 may be increased and vice-versa when there is lesser liquid or contaminant on cleaning surface 11.
Thereto, for the cleaning device 510 to successfully clean surface 11 effectively, regeneration or restoration of the absorbent material 518 to its original or restored condition (so that it can be reused to clean the surface) has to take place when carriage J5 continuously or constantly travels in the direction of arrow 101 and 110 alternatingly whilst portion of the absorbent material 518 renlairis in contact with the cleaning surface 11 coming into contact with the contaminant din and debris from said surfhce 11 and collects it via cohesion, absorption and adherence causing the absorbent material 518 to accumulate contaminant dirt and debris on and within the absorbent material 518 so that the body of the absorbent material becomes polluted, dirty or degenerated before entering the liquid catchnient means enclosure module JS for regeneration or restoration. At this particular stage wherein the permeable body and tce of the absorbent material 518 carries contaminants dirt and debris and is about to enter liquid catchment ieans enclosure module is, absorbent material 518 is referred to as being in a diny or degenerated condition. The regenerat ion of the absorbent material 418 in the fourth embodiment operates in the same or similar method and process as the regeneration of the absorbent material 318 in the third embodiment While the absorbent material 518 is in a degenerated or dirty condition or state, no effective cleaning of surface 11 may take place when the absorbent material 518 is passed over the surface 11, unless the absorbent material is restored to a clean and semi dry condition via cleaning. Cleaning the absorbent material 518 involves removing contaminant dirt and debris that is previously collected by the absorbent material from cleaning surface 11 so that the degenerated absorbent material 518 is transformed into a regenerated or restored absorbent material which can then be reused to continuously clean surface I l.Therefore, as the degenerated or dirty absorbent material 518 carrying contaminant dirt and debris meets J5 and enters the liquid catchment means enclosure module J5 via -p a receptacle or opening. delivering contaminant dirt and debris into a compartment in J5. Thus, once portion of the absorbent material 518 enters the liquid catehment means enclosure module J5 and is within the first compartment. successive rcgSneratio,j or restoration cleaning steps are carried out within J5 to clean the absorbent material 518. These steps may include one or more or the combination of(i) removing dirt and debris from the object, (ii) soaking and washing an object (iii) rinsing the object (iv) and drying the object. However when regenerating the absorbent material 518 within the liquid catchment means enclosure module J5, certain steps may be eliminated, added or extended and still attain the equivalent result ofa clean dry or semidry absorbent material 518, or so long as the absorbent material 518 can be reused continuously to clean the surface 11 appropriately by the cleaning device Sift. The cleaning steps undertaken Within.15 begin when the absorbent material 518 may encounter a scraping means in the form of rotating brush which begins the process of removing impurities contaminant dirt and debris from the face and permeable body of the absorbent material 518. A rotating brush may replace the scraper so that it shears and dislodges loosely held particles and debris from portion ofthe passing absorbent material 518 by rubbing off or flicking. Dirt and debris is then evacuated from the first compartment by suction lotte or other evacuation means in the direction away from J5 of via drainage port for disposal (not shown). Next, a liquid applicator (not shown) may discharge or elect rinsing liquid onto face and body of the absothent material 518.
The liquid applicator (not shown) is fluidly connected to a conduit which delivers clean liquid into liquid applicator on the first compartment or liquid applicator in the second compartment respectively as governed by the direction of the absorbent material 518. Thus, there may be liquid control valve in-between said liquid applicators. The clean liquid conduit (not shown) is fluidly connected to clean liquid storage tank (M) which may either be situated within the body of the cleaning device Sift or away so that clean liquid is delivered from a clean liquid source away from the cleaning device, e.g a water mains source. Discharged, squirted or sprayed clean liquid flushes, cleanses and soaks into the body of the absorbent material 518 thereby rinsing, dissolving, diluting, loosening and dispersing contaminant particulates collected from surface 11, and including mixtures of dirt and waste liquids held within the porous body of the absorbent material 518 and sending said dislodged contaminants mixture in a direction away from the permeable body of the absorbent material. Waste liquid is then evacuated from the compartment by pumping means or via suction force 82a (or negative pressure 112) via drainage port fluidly connecLed to conduit for disposal. At this stage, portion ofthe absorbent material 518 in the compartment is soakedet and waiting to be wrung. Portion of the absorbent material 518 is then ingested in-between the tbrce of rollers 514 and rigid support structure 519.
There is provided a central wall (not shown) which divides the waste liquid from the following uncontaminated compartment so that effective cleaning and wringing of the absorbent material takes place. As portion of the absorbent material 518 becomes compressed, sandwiched and gripped in-between the compressing force of the surface of rollers 514 against support structure 519, temporarily compress portion of the resilient porous body of the absorbent material 518 forcing the spent mixtures of contaminant waste liquid and dissolved particles therein to be expelled from the permeable body of the absorbent material 518, so that as portion of the absorbent material emerges -4.
(whilst regaining shape) from the other side of the rollers 514, absorbent material 518 is in a clean dry and or semidry condition. Thusly, the degenerated portion of the absorbent material 518 previously in the first compartment (of liquid applicator) is now in the second compartment (of muted liquid applicator) having been transformed into a regenerated or restored clean condition ready to become reused by the cleaning device 510 to clean surface 11 once it re-emerges as.15 moves away at direction of arrow 554 (see FIG 65). Therefore, as i5 nlcves in the direction of 554, the absorbent material on trio side.15 is moving toward isdegenerated whilst portion of the absorbent material behind 35 is regenerated and can be used to clean a dirty surface 11. and the cycle continues. An advantage of this example of the cleaning device 510 according to this patent disclosure is that it shall save strenuous and unnecessary housework chores which involve changing mierofiber pads in between cleaning operations thereby increasing risks during walks on wet surfaces; washing microfiber pads and cloth in high electricity consuming temperatures on heavy dirt settings on washing machines which subsequently consume many times over the amount of water the cleaning device 510 would consume to clean the absorbent material 518, and whilst bearing in mind that the cleaning device 510 herein is passed over a cleaning surface 11 once. Peace ofmind may be attained to a user of the cleaning device herein through knowing that a cleaning chore can be simplified and carried out without interruption or user intervention every now and then as is so common with prior art floor cleaning apparatuses. Cleaning device 510 may also carry a surface_liquid applicator 597 (see FIG 65a) proximate to surface 11 arranged to apply a cleaning fluid or a rinsing fluid such as water onto (lie surface II. Cleaning fluid maybe drawn fro,i storage tank and administered with soap as if required. Thus, when necessury, plain orpure watercan be used for rinsingthe surface II prior to passing the absorbent material 518 over so that the absorbent material 518 may be rinsed' indirectly before encountering iS. In such a constitution, it may not be necessary to have liquid applicators within J5 since (indirect) rinsing is done via 597. Cleaning and rinsing fluid may be pumped from source storage tank (NI) or delivered to the outlet of surface-liquid applicator and or to outlet of surface-liquid applicator via gravity once a valve liquid release mechanism is actuated, however, a pump may he Utilized instead. Surface-liquid applicators may also be used for the purpose of indirectly rinsing the surfacefl before the spent liquid mixture is collected by the absorbent material 518. It should also be noted herein that roller 514 may be adapted to be hollow and have perforations and a suctioning force therein so that liquid ejected from the absorbent material 518 may be forced into (he perforated roller 514 for disposal. In such a constitution, there would be provided a flexible tube connected to at least one end of the (perforated) roller 514 so that the waste liquid and debris is evacuated through such a tube for disposal. Similarly, JS can be modified into a cup touching 51 Son open side and being the length ofiS and said cup containing a powerful suctioning force delivered via a flexible tube so that instead ol'a cornprcssin element such as roller 514 ejecting waste liquid from the absorbent material 518. a powertijl burst of gas with high negative pressure maybe used to pull waste liquid and debris away from the exposed portion of 518.
Referring now to FIG. 67 to FIG. 73 of the sixth embothment of the present invention the block shaped absorbent material 518 in the preceding embodiment can be modified further by extending the shape of the absorbent material 618 in this example where 618 is also permanently fixed yet still adequately performing the task of cleaning a surface Ii whilst being Continuously regenerated or restored without user intervention and the absorbent material 618 may be configured to become regenerated in much the same way as described above, but with the roles of the same components reversed; that is, the liquid catchment means enclosure nioduJe J6 is a moveabje carriage that is Configured to follow a fixed track so as to trail a permanently fixed or stationary absorbent material 618, for regeneration or restoration. Therefore instead of the passing absorbent material 618 been led into a stationary liquid catchment means enclosure module (e.g JI or J4) as it is described above in the preferred and other embodiments of this patent disclosure, the liquid catchment means enclosure module J6 is movable and follows the absorbent material 61$ to and fro (at direction of 654 and vicC-versa)for regeneration during a cleaniiij operation on cleaning surface U. Therefore a main difference with the configuration ofthe absorbent material 518 in the preceding embodiment with this example of the sixth embodiment is that with the fifth embodiment, the absorbent material 518 is permanently fixed while J5 moves along by revolving, rotating or to and fro along the body of the absorbent material 518 to perform the crucial task of regeneration on the absorbent material 518
according to the spirit of this patent disclosure.
With reference to FiG 69 there is provided an inflexible and stationary rigid disc plate-support structure 619 having fixed onto it the absorbent material 618 which is on contact with the cleaning surface 11. The absorbent material 618 is a circularly or disc shaped block body which is firmly fixed onto support structure 619 also fixed on the cleaning head 610 attached to a handle, so that regeneration of the absorbent material 618 which is in constant contact with the surface 11 is carried out without lifting the cleaning head 610 from the cleaning surface Ii during a cleaning operation.
The device generally incJudes a handle, connected to a housing of the cleaning head 610 which includes the absorbent material 618, supporrtructure 619, mounted waste liquid tank 1< and waste liquid tank N'!, a tracked rack and pinion assembly which is rotatably connected to J6 and includes at least one rotatable pinion gearwheel 626 and a fixed rack gearwheel 628 mounted on the chassis of cleaning head 610, means to power gearwheel 626 (loined to.J6) so that the carriage of Jo is able to rotate around axis line 6b at direction of arrow 654 along the track of rack gearwheel 628 (or when rotating at opposite of arrow 654). Roller 614 rotates in the direction of arrow 627 (when rack gearwheel 628 rotates at direction of arrow 654) and fixed inside liquid catchment means enclosure module J6 whilst also pressing on portion of immovable absorbent material 618 fixed onto rigid disc plate-support structure 619. The rack gearwheel 628 isjoined to J6 and is rotatably fixed around axis line 6b. J6 and rack 628 are further rotatably connected to the handle at axis 6b whilst pinion gearwheel 626 and wheel 6O4a are fixed to each other and share the same axis 6a. Gearwheel 626 and wheel 604a are also connected to chassis member 699 which is firmly connected to non-rotatable part oihandje base at axis 6k Absorbent material 618 is fixed onto rigid disc support structure 619 so that roller 614 inside 16 rotates at direction of arrow 627 when rack gearwheel 628 rotates at direction of arrow 654 because pinion gearwheel 626 rotates at directon of arrow 629 and arrow 623 together respectively with wheel 604a which is in frictional contact with surface II when moving the creaning head 610 over the cleaning surface 11 ala direction according to arrow 101. On the other hand, wheel 604 rotates in the direction of arrow 623 and is firmly connected to gearwheel 624 (also rotating at direction 623a). Gearwheel 624 meshes with gearwheel 624a so as to subsequently rotate in the opposite direction according to arrow 623b. Gearwheel 624a meshes with rack gearwheel 628 which rotate at the direction according to arrow 654 so that both wheels 604a and 604 are rotating in the same direction according to arrow 623. Wheel 604, gearwheels 624 and 624a are rotatably connected via holes (on 698) to the chassis of the cleaning device 610; whilst pinion gearwheel 626 and wheel 604a are supported and rotatably connected via holes to chassis member 699. Chassis member 698 is firmly connected to a non-rotatable part of handle base. Thus when the cleaning device 610 is pushed across surface II according to direction of arrow 101, J6 rotates at direction of arrow 654 so that the absorbent material 618 in contact with the cleaning surface 11 is continuously compressed in-portion by roller 614 inside J6 where there is constantly a portion of absorbent material 618 exposed therein as it continuously enters and exits.16 to recommence contact with the cleaning surface 11. Therefore whether the cleaning device 610 is moving acmss surface 11 in direction 101 or 110, the compressing oF the absorbent material 618 wil/ continuously happen at either direction with J6 rotating at the direction opposite arrow 654. Some. sidewalls ofJ6 on the example drawings have been omitted for clarity. During operation the absorbent material 618 is clamped tightly (against the absorbent material 518 and rigid disc support structure 619) along the circumferential perimeter of gearwheel 628 extends. Roller 614 is rotatably mounted within J6 so that the body of the absorbent material 618 is compressed adequately to remove contaminant liquid therein. A pair of waste liquid tanks (M for clean liquid) and (K for waste liquid and debris) are mounted upon chassis members 699, 697. Frame members 699, 697 remain Fixed at line 6c (or is perpendicular to arrow 101 and 110) whilst support structure 619 holding absorbent material 618 rotate around axis 6b. There may be provided liquid applicators (not shown) and drainage ports (not shown) connected inside J6 in the equivalent method of previous embodiments of this patent disclosure. Immovable absorbent material 618 enters and exits the moving liquid eatchment means enclosure module J6 in an entry and exit continuous mechanism so that continuous and uninterrupted regeneration or restoration of the absorbent material 6i8 in contact with dirty surface 11 is coifstantly regenerated without interruption or any user intenention during the user's domestic or industrial cleaning task. In this example, the absorbent material 618 is a circular block; however, the absorbent material 618 may be configured in any other shape such as rectangular, pyramidal, circular, a combination of shapes such as rectangle and circular (see next embodiment), elliptical or any other shape conceivable. The absorbent material 618 may also include more than one texture on it such as a scraping or scouring portion or spaced strips of scouring material interwoven or vulcanised adjacent to the liquid soaking absorbent material 618. It may also be possible for the absorbent material to be fixed onto the support structure 619 via easy-screws or other means for example Velcro. 7o
With reference to FIG 6Th the absorbent material 618 is in contact with a surface 11 and supported thereupon via a handle by user (not shown). During operation, as the carriage of J6 rotates around the perimeter of rack 628, the bottom of.16 may come into contact with the surface 11; therefore to avoid damaging the floor or any other surface, there may be a rolling element such as arbitrary wheels or rollers placed underneath the carriage of.16. Also, a brushing or scraping element may be positioned thereunder so that with user actuation, the scraper may be utilized to fbr example scrape stubborn dirt from a surface, remove chewing gum or hardened liquids. The rollers under.16 also ensure that the cleaning device 610 works independently without interfering with the sideways orto and iro direction at which the user steers the cleaning device when pulling and pushing to the forward and backward motion as is commonly done when using any prior art floor cleaning apparatuses. Action of a brush and or scraper underneath J6 may also help the user to keep their domestic or industrial surfaces cleaner and in a more convenient and quicker way, thereby saving strenuous unnecessary cleaning hardships for the user of the cleaning device disclosed herein.
With reference to FIG 69 to FIG 73, liquid catchment means enclosure module.16 moves through immovable absorbent material 618 so that part or portion of the absorbent material 618 remains constantly enclosed within the liquid catchment means enclosure module.J6 whilst portion of the body of the absorbent material 618 remains exposed and in contact with surface 11. Motive energy is delivered via kinetic energy through frictional contact of wheels 604 and 604a as described above.
Roller 614 compresses portion of the passing absorbent material 618 continuously regardless of intermittent direction 101 or lift moved. Si6ce the flexible absorbent material 618 is sandwiched along the length ofthe surface olroller 614 and firmly against support structure 6t9, any liquid held within the absorbent material's body is forced away every time the carriage J6 moves from side (101) to side (110) in a continuously frequency as best required. When the amount of contaminant or liquid is much on the surface 11, the frequency of.16's revolutions may be increased via gears and vice-versa when there is lesser liquid or contaminant on cleaning surface 11. Cleaning device 610 has an advantage of saving electrical power. However, it is possible to have the cleaning device 610 to use electricity by connecting the major drive-gearwheels with motors.
Thereto, for the cleaning device 610 to successfully clean surface 11 effectively, regeneration or restoration of the absorbent niaterial 618 to its original or restored condition (so that it can be reused to clean the surface) has to take place when carriage J6 continuously or constantly travels in the direction of arrow 654 or vice versa so that portion of the absorbent material 618 remains in contact with the cleaning surftce 11 coming into contact with the contaminant dirt and debris from said surice II and collects it via cohesion, absorption and adherence causing the absorbent material 648 to accumulate contaminant dirt and debris on and within the absorbent material 618 so that the body olthe absorbent material becomes polluted, dirty or degenerated before entering the I quid catchrnent means enclosure module.J6 for regeneration or restoration. At this particular stage wherein the permeable body and face of the absorbent material 618 carries contaminants dirt and debris and is about to enter liquid catchment means enclosure module J6, absorbent material 618 is referred to as being in a dirty or degenerated condition. The regeneration of the absorbent material 518 in the fifth embodiment operates in the same or similar method and process as the regeneration of the absorbent material 418 in the third embodiment.
While the absorbent material 618 is in a degenerated or dirty condition or state, no effective cleaning of surface 11 may take place when the absorbent material 618 is passed over the surface 11, unless the absorbent material is restored to a clean and semi dry condition via cleaning. Cleaning the absorbent material 618 involves removing contaminant dirt and debris that is previously collected by the absorbent material from cleaning surface 11 so that the degenerated absorbent material 618 is transformed into a regenerated or restore absorbent material which can then be reused to continuously clean surface il.Thereforc, as the degcnerated or dirty absorbent material 618 carrying contaminant dirt and debris meets J6 and enters the liquid catebment means enclosure module J6 via a receptacle or opening, delivering contaminant dirt and debris into a compartment in J6. Thus, portion of the absorbent material 618 enters the liquid catchment means enclosure module 36 and is within the first compartment, successive regeneration or restoration cleaning steps are carried out within.16 to clean the absorbent material 618. These steps may include one or more or the combination of(i) removing dirt and debris from the object, (ii) soaking and washing an object (iii) rinsing the object (iv) and drying the object. However when regenerating the absorbent material 618 within the liquid catchment means enclosure module J6, certain steps may be eliminated, added or extended and still attain the equivalent result of a clean dry or semidry absorbent material 618, or so long as the absorbent material 618 can be reused continuously to clean the surface 11 appropriately by the cleaning device 610. The cleaning steps undertaken within J6 begin when the absorbent material 618 may encounter a scraping means in the form of rotuing brush which begins the process of removing impurities contaminant dirt and debris from the face and permeable body of the absorbent material 618. A rotating brush may replace the scraper so that it shears and dislodges loosely held particles and dcbris from portion ofihe passing absorbent material 618 by rubbing off or flicking. Dirt and debris is then evacuated from the first compartment by suction force or other evacuation means in the direction away from J6 of via drainage port for disposal (not shown). Next, a liquid applicator (not shown) may discharge or eject rinsing liquid onto face and body of the absorbent material 618.
The liquid applicator (not shown) is fluidly connected to a conduit which delivers clean liquid into liquid applicator on the first compartment or liquid applicator in the second compartment respectively as governed by the direction of the absorbent material 618. Thus, there may be liquid control valve in-between said liquid applicators. The clean liquid conduit (not shown) is fluidly connected to clean liquid storage lank (M) which may either be situated within the body of the cleaning device 610 or away so that clean liquid is delivered from a clean liquid source away from the cleaning device, e.g a water mains source. Discharged, squirted or sprayed clean liquid flushes, cleanses and soaks into the body of the absorbent material 618 thereby rinsing, dissclving, diluting, loosening and dispersing contaminant particulates collected from surfae 11, and including mixtures of dirt and waste liquids held within the porous body oithe absorbent material 618 and sending said dislodged contaminants mixiure in a direction away from the pcrmeae body of the absorbent material. Waste liquid is then evacuated from the compartment by pumping means or via suction force 82a (or negative pressure 112) via drainage port fluidly connected to conduit for disposal. At this stage, portion of the absorbent material 618 in the compartment is soaked wet and waiting to be wrung. Portion of the absorbent material 618 is then ingested in-between the force of rollers 614 and rigid support structure 619.
There is provided a central wall (not shown) which divides the waste liquid from the following uncontaminated compartment so that effective cleaning and wringing of the absorbent material 618 takes place. As portion of the absorbent material 618 becomes compressed, sandwiched and gripped in-between the compressing force of the surface of rollers 614 against support structure 619, temporarily compresses portion of the resilient porous body of the absorbent material 618 forcing the spent mixtures of contaminant waste liquid and dissolved particles therein to be expelled from the permeable body of the absorbent material 618, so that as portion of the absorbent material emerges (whilst regaining shape) from the other side of the roller 614, absorbent material 618 is in a clean dry and or semidry condition. Thusly, the degenerated portion ofthe absorbent material 618 previously in the first compartment (of liquid applicator) is now in the second compartment (of muted liquid applicator) having been transformed into a regeneratcd or restored clean condition ready to become reused by the cleaning device 610 to clean surface 11 once it re-emerges as.J6 moves away at direction of arrow 654. Therefore, as J6 moves in the direction of 654, the absorbent material on the side J6 is moving toward is degenerated whilst portion of the absorbent material behind J6 is regenerated and can be used to clean a dirty surface 11, and the cycle continues. An advantage of this example of the cleaning device 610 according to this patent disclosure is that it shall save strenuous and unnecessary housework chores which involve changing microfiber pads in between cleaning operations thereby increasing risks during walks on wet surfaces; washing microfiber pads and cloth in high electricity consuming temperatures on heavy dirt settings on washing machines which subsequently consume many times over the amount of water the cleaning device 610 would consume to clean the absorbent material 618, and whilst bearing in mind that the cleaning device 610 herein is passed over a cleaning surface ii once. Peace of mind may be attained to a user of the cleaning device herein through knowing that a cleaning chore can be simplified and carried out without interruption or user intervention every now and then as is so common with prior art floor cleaning apparatuses.
Cleaning device 610 may also carry a surface-liquid applicator (not shown) proximate to surface 11 arranged to apply a cleaning fluid or a rinsing fluid such as water onto the surface 11. Cleaning fluid may be drawn from storage tank and administered with soap as if required. Thus, when necessary, plain or pure water cmi be used for rinsing the surface 11 prior to passing the absorbent material 618 over so that the absorbent material 518 may be rinsed' indirectly before encountering J6. In such a constitution, it may not be necessary to have liquid applicators within J6 since (indirect) rinsing is done via said liquid applicator. Cleaning and rinsing fluid may be pumped from source storage tank (NI) or delivered to the outlet of surface-liquid applicator and or to outlet of surface-liquid applicator via gravity once a valve liquid release mechanism is actuated, however, a pump may be utilized instead. Surface-liquid applicators may also be used for the purpose of indirectly rinsing the surface II before the spent liquid mixture is collected by the absorbent material 618.
It should also he noted herein that roller6l4 may be adapted to be hollow and have perforations and a suctioning force therein so that liquid ejected from the absorbent material 618 may be forced into the perforated roller 614 for disposal. In such a constitution, there would be provided a flexible tube connected to at least one end of the (perforated) roller 614 so that the waste liquid and debris is evacuated through such a tube for disposal. Similarly. J6 can be modified into a cup touching 618 on open side and being the length ofJo and said cup containing a powerful suctioning force delivered via a rotatable junction tube at intersection of axis 6a and 6b (see FIG 73) or flexible tube so that instead of a compressing element such as roller 614 ejecting waste liquid from the absorbent material 618, a powerful burst of gas with high negative pressure may be used to pull waste liquid and debris away from the exposed portion of 618.
Referring now to FiG. 74 to FIG. 79 of the sixth embodiment of the present invention the block shaped absorbent material 618 in tis modified to an extended version 6618. in fact, almost every element between FIG 74 to FIG 79 is a modification of same parts between FJG 67 to FIG 73.
Elements between FIG 74 to FIG 79 have an addition 6 for example; absorbent material 618 is 6618 in the modified example. In the modified example, J6 is powered by a motor attached either pinion 6626 or 6626a. The modified sixth embodiment also contains more than one rack gearwheel 6628 (w/er) and 6628a (inner). All in all, modified embodiment of the sixth embodiment works in the same way as above. An advantage of the mOdified example is that it has a wider width cleaning footprint which can he ideal for cleaning large floor surfaces e.g in supermarkets, hospitals and airports. Thusly, the liquid catchment means enclosure module carriage may be transported around the permanently fixed absorbent material by been connected to transport means such as, on a track, rail, chain, rack and pinion arrangement, a centrally or diametrically position rotatable boom arm connection that rotates around the centre of a circularly and permanently fixed absorbent material. It may be possible to have the liquid catchment means enclosure module carriage on a non-circularly arrangement such as when the movable liquid catchment means enclosure module carriage moves to and fro along a crossways or sideways motion to regenerate a permanently fixed block absorbent material operating on a cleaning head during a cleaning cycle on cleaning surface.
The structural cross-section shape of the permanently fixed absorbent material that is fixed on rigid support structure by gluing or clamping etc., so that the movable liquid catchment means enclosure module carriage moves to and Fm or revolves or rotates around a guide rail may be triangular, circular, cylindrical, oval, elliptical, ring, rectangular, strands or filaments of material, hexagonal etc., and may he a blend of one or more cleaning materials such as a coarser less absorbent material, and a smoother more absorbent material.
In embodiments of the cleaning device disclosed in this patent, there may be provided a separate flexible clean liquid bottle and a separate flexible dirty liquid bottle which are adjacently placed together inside a rigid volume formed with or without various contours to conform to the space available on the body of the cleaning device. Therefore and with reference to FIG SO and FIG SI, there is provided a rigid volume 8a which therein are flexible container Sb for the clean liquid storage NI, and a flexible container Sc for the waste liquid and debris storage K. The separate waste liquid storage container K and clean fluid storage container NI are flexible liquid containers that are collapsible and housed together in a rigid volume, so that maximum volume of cleaning fluid is able carried or transported by the cleaning device described herein. The advantage of this flexible containers Sb and 8c is that during operation in the cleaning device e.g from first embodiment 10, as the cleaning fluid 64 is being depleted from the flexible clean fluid storage container Sb, a reciproeatPng action of the volume of the depleting cle..ning fluid from the clean fluid storage container 8b is replaced or exchanged into the adjacent container (Sc) increasing the volume of the flexible iiste liquid storage container Sc therein 8a so that as more spent or waste liquid consisting of mixture of spent cleaning fluid 64 and dislodged contaminants are collected from the cleaning surface 11, container Sc becomes larger in size whilst container Sb reduces in size (see P1080 and the reverse on FIG 81). Therefore, as clean liquid is being used from one eontainer8b, according to arrow 3d the other container Sc receives the spent clean liquid according to arrow Se (and also according to the dirt evacuation means of the cleaning device herein) and contaminants so that the volume or space where the clean liquid once occupied within rigid volume 8a is used by the increasing volume of waste liquid 66 in Sc. When the waste liquid container fills the volume Sa, it may be emptied by a user of the cleaning device herein. One group of people who would find an advantage in using a cleaning device which maximally employs waste liquid and clean liquid space are busy restaurant attendants, chefs, and also as a surface cleaning apparatus e.g on public lavatories when not at home. Another advantage of this collapsible aspect of the clean fluid storage container Sb and the waste liquid storage container Sc, is that in smaller embodiments ofthc cleaning device herein, particularly, with the hand-held and or palm-sized version of the cleaning device, maximum usage of space within the body of thc cleaning device may be maintained, however, the same aspect may be used in larger embodiments of the cleaning device described herein. Another advantage of the cleaning device is that the contamination of cleaning liquid and dirty liquid is prevented by providing separate flexible clean fluid storage container Sb and waste liquid storage container Sc. The flexible containers Sb and Sc of embodiments of the cleaning device in this patent disclosure maximally employ volume within an enclosure within the cleaning device by way of using watertight collapsible integrated liquid containers with separate reciprocation pockets of waste liquid and cleaning fluid as the liquids are being used within the chassis of the cleaning device. These flexible containers Rb and Sc are prefcrably made from a lightweight, durable and flexible material such as rubber, plastic or any other practicable material.
Referring now to FIG. 82 and FIG. 83 of the seventh embodiment of the present invention is a completely different configuration and method in which he absorbent material 718 is restored or regenerated so that continuous uninterrupted nd without user intervention of the cleaning device 710 cleanins a surface I P is adequately niaintained according to the spirit of this patent disclosure. In this embodiment instead oldie passing ahsorbentThaterial 718 been led into a stationary liquid catchment nieans enclosure module (e.g JI or J4) as it is described above in the preferred and other embodiments of this patent disclosure, or J6 being a movable carriage which regenerates the absorbent material 618 in the sixth embodiment, in this seventh embodiment, the absorbent material 718 uses inertia centrifugal force to remove waste liquid and debris from the absorbent material 718.
The centrifugal force is applied onto the absorbent material via spindle element support structure 719 wherefrom strands of the absorbent material are fixed 718 and radially radiate therefrom.
With reference to FIG 83 there is provided strands of absorbent material 718 radially fixed around spindle element support structure 719. Portion of radial strands of absorbent material 718 are in contact with the cleaning surface 11 whilst portion of strands 718 are within the liquid catchment means enclosure module J7. The strands of absorbent material 718 radiate circularly and may be shaped in single strands which are firmly fixed onto support structure 719 which is also rotatably fixed on the cleaning head 710 attached to a handle, so that regeneration of the strands of absorbent material 718 which is in constant contact with-the surface Ills carried out without lifting the cleaning head 710 from the cleaning surface ii during a cleaning operation by user. Therefore, the cleaning device 711) may generally include a handle element, connected to a housing of the cleaning head 710 which includes the absorbent material 718, support structure 719, mounted (flexible or non-flexible) waste liquid tank K and waste liquid tank M, a motor (not shown) or kinetic energy conversion gear means to rotate the spindle support structure 719 at revolutions suitable enough for sufficient removal of waste matter from strands 718 via centrifugal force. A pumping means or suction means (not shown) to evacuate waste liquid and debris (759,766 collected from surface 11) from J7 via conduit 780 and at direction of arrow Q for disposal in waste bottle K, and similarly, a pumping means (not shown) for delivery of clean rinsing liquid 764 from clean liquid bottle M via conduit 786 at direction of arrow 73 and to liquid applicator 760 in J7.
During operation, the absorbent material 718 which is mounted on rotatably spindle support structure 719 on the cleaning head 710, rotates at a direction ofarrov 754 so that the strands 718 which are in contact with the surface 11 are spun arounSat a suitable speed and then flung or made to strike flicking element 714. When absorbent material strands 718 are flicked against the flicking element 714, lose dirt and debris 759,766 and including mixture of spent liquids are deposited on receptacle behind flicking element 714.The receptacle behind flicking element 714 is connected to one or more drainage port 780 which sends dirt and debris 759,766 to waste bottle K for disposal according to direction of arrow Q. Therefore dirt and debris collected from the surface 11 is transferred from said surface and deposited onto the cleaning device 710 waste bottle K leaving the surface in clean state.
As the strands of the absorbent material 718 leave the region of the flicking means 714, it is in a dry and clean state and is ready to come into contact with the cleaning surface LI. There may be provided a liquid applicator 760 within J7 which ejects clean liquid 764 onto the absorbent material 718 before the strands strike flicking element 714; this ensures that the absorbent material is rinsed before the waste liquid is urged from the body of the strands 718. Similarly, there may be provided liquid applicator (not shown) which ejects clean liquid 764 on the surface 11 before the cleaning head 710 is passed over said surface 11. There may be also provided at least one flexible blade 744 such as a doctor-blade which ensures that the dirt and debris is transported into J7 of the cleaning device 7J0.
The cleaning device 710 has a width conguration such as that of the second, third or sixth embodiment. Thereto, absorbent material 718 enters and exits liquid catehment means enclosure module J7 in an entry and exit continuous mechanism so that continuous and uninterrupted regeneration or restoration ofthe absorbent material 718 in contact with dirty surface 11 is constantly regenerated without interruption or any user intervention during the user's domestic or industrial cleaning task. The absorbent material 718 may also include more than one textural surface for example, a scouring strips and leather straps interwoven or vulcanised adjacent to each other.
In summary, for the cleaning device 710 to successfully clean surface 11 effectively, regeneration or restoration of the absorbent material 718 to its original or restored condition (so that it can be reused to clean the surface) has to take place when absorbent material 718 continuously or constantly travels into J7 in the direction of arrow 754 so that portion of the absorbent material 718 remains in contact with the cleaning surface 11 coming into contact with the contaminant dirt and debris from said surface Ii and collects it via cohesion, absorption and adhrence causing the absorbent material 718 to accumulate contaminant dirt and debris onand within the absorbent material 718 so that the body of the absorbent material becomes polluted, dirty or degenerated before entering the liquid catchment means enclosure module J7 for rcgcneration or restoration. At this particular stage wherein the permeable body and strands of the absorbent material 718 carries contaminants dirt and debris and is about to enter liquid catchment means enclosure module J7, absorbent material 718 is said to as being in a dirty or degenerated condition. The regeneration of the absorbent material 6IS in the sixth embodiment operates in the same or similar method and process as the regeneration of the absorbent material 318 in the third embodiment.
While the absorbent material 718 is in a degenerated or dirty condition or state, no effective cleaning of surface 11 may take place when the absorbent material 718 is passed over the surface 11, unless the absorbent material is restored to a clean and semi dry condition via cleaning. Cleaning the absorbent material 718 involves removing contaminant dirt and debris that is previously collected by the absorbent material from cleaning surface 11 so that the degenerated absorbent material 718 is Irunslbrmed into a regenerated or restored absorbent material which can then be reused to continuously clean surlace I1.Once the absorbent material 718 makes a complete revolution around axis of spindle structure 719, the absorbent material is completely regenerated as described above and the cycle continues. The cleaning device 710 may be now used to clean the surface 11 at the direction according to 101 or 110. There may be provided wheels (shown in dotted lines) under the cleaning head 710. There may also be an alternating mechanism to lift the cleaning device inwards or outwards so that it may make contact with the cleaning surface durirg use or vice versa.
Relëj-rinu now to FIG. 84 Io FIG. 88 ol the eighth embodiment is a modification of the second or third embodiment in this patent disclosure. However, the difference between this eighth and second embodiment is that in the second embodiment, liquid catchment means enclosure module J2 has mechanical rollers and gearwheels, however, in this eighth embodiment, liquid catchmeut means enclosure module.18 has no mechanical parts because gas under pressure is utilized to remove dirt and debris from the body of the absorbent material 818. The rest of the way the absorbent material works in this eighth embodiment in equivalent to how the absorbent material works in the second or third embodiment; and the way in which the absorbent material 818 is regenerated in this eighth embodiment is equivalent to how the absorbent material 218 is regenerated with the only difference being the type of liquid urging means method is used. The configuration of the absorbent material 818 in this eighth embodiment is similaror resembles a caterpillar digger's track wheels or military tank's motive track mechanism.
With reference to FIG 84a to FIG 86, the absorbent material 818 is attached to support structure 819 and roate by guide wheels 891 which are held in place by support member connected to the chassis of' the cleaning apparatus 810. Guide wheels 891 is rotatably fixed support structure 819 which is a belt loop with grooves on one side which intermesj with grooves on guide wheels 891. Guide wheels 891 allows for continuous rotation of the absorbent material 818 (which is fixed on the non-grooved side of 891) to be achieved at either clockwise or antielockwise direction. One or more guide wheels 891 provide the energy to rotate the absorbent material 818 attached to the support structure 819. Thus the support structure 819 may rotate revolve eccentrically whilst supporting the absorbent material entering and leaving liquid catchment means enclosure module J8 for regeneration The support structure is annular or ring shaped structure 819 whereto the absorbent material 818 is attached. There is also provided a liquid applicator 860 in.18 which ejects clean liquid 864 on passing absorbent material 818. Dirt and debris evacuated from the absorbent material 818 is sent for disposal by suction force 82a via drainage port 872 to waste tank K. Clean liquid 864 is delivered to liquid applicator 860 via conduit 861 which is fluidly connected to conduit which delivers same liquid to a liquid applicator 836 which ejects clean liquid 837 in the fore region of the cleaning device, and is also connected to a clean liquid storage container M. With reference lo FIG 84c, FIG 85 during r4cneration the absorbent material 818 fixed to support structure 819 and iravelling around members 891 and through J8 so that part or portion of the absorbent material 818 remains constantly enclosed within the liquid catchment means enclosure module.18 whilst portion of the body of the absorbent material 818 remains exposed and in contact with surface II.
Thereto, for the cleaning device 810 to successfully clean surface ii effectively, regeneration or restoration of the absorbent material 818 to its original or restored condition (so that it can be reused to clean the surface) has to take place at the same time as the absorbent materiaf 818 continuously or constantly travels in the direction of arrow 855, and comes into contact with the surface 11 collecting contaminant dirt and debris from said surface 11 via cohesion, absorption and adherence causing the absorbent material 818 to accumulate contaminant dirt and debris on and within the absorbent material 818 so that the body of the absorbent material 818 becomes polluted, dirty or degenerated befhre entering the liquid catchmei-it means enclosure module J8 for regeneration or restoration. At this particular stage wherein the permeable body and face of the absorbent material 818 carries contaminants dirt and debris and travels in direction of arrow 854, and is about to enter said liquid catch nient means enclosure module iS, absofbent material 818 is referred to as being in a dirty or degenerated condition. The regeneration of the absorbent material 318 in the third embodiment operates in the same or similar method and process as the regeneration ofthe absorbent material 18 in the first embodiment.
While the absorbent material 818 is in a degenerated or dirty condition or state, no effective cleaning ofsurface Ii may take place when the absorbent material 818 is passed over the surface 11, unless the absorbent material is restored to a clean and semi dry condition via cleaning. Cleaning the absorbent material 818 involves removing contaminant dirt and debris that is previously collected by the absorbent material from cleaning surface ii so that the degenerated absorbent material 818 is transformed into a regenerated or restored absorbent material which can then be reused to continuously clean surface 1l.Therefore, as the degenerated or dirty absorbent material 818 carrying contaminant dirt and debris from surface 11 travels according to direction of' arrow 854, it continuously enters the liquid calebment means enclosure module.18, delivering contaminant dirt and debris into a compartment in 38. Thus, oncc.portion of the absorbent material 818 enters the liquid catch -neni means enclosurc module 38 and is within the first compartment successive regeneration or restoration cleaning steps are carried out within 38 to clean the absorbent niateriai 818. These steps may include one or more or the combination of (i) removing dirt and debris from the object, (ii) soaking and washing an object (iii) rinsing the object (iv) and drying the object. However when regenerating the absorbent material 818 within the liquid catchment means enclosure module J8, certain steps may be eliminated, added or extended and still attain the equivalent result of a clean dry or semidry absorbent material 818, or so long as the absorbent material 818 can be reused continuously to clean the surface 11 appropriately by the cleaning head 810. The cleaning steps undertaken within the 38 begin when the absorbcnt material encountering a scraping means or brushing means (not shown) begins the process of removing impurities contaminant dirt and debris from the face and permeable body of the absorbent material SlS.Before dirt and debris is removed from the absorbent material 818, portion of the absorbent material may be soaked with clean fluid 864 so that dirt is loosened and a rinsing effect is applied on 818 prior to high velocity suction pressure 82a is applied on the body of the absorbent material 818 moving at direction of arrow 854 and still degenerated. Liquid catchment means enclosure 38 is presently divided with a wall so that liquid is applied sufficiently in the first compartment at direction 854 of 818. Once degenerated portion of absorbent material 818 is inside J8 and passed the dividing wall, 818 encounters a powerful gaseous force 82a which takes away all the dirt and debris collected from the surface 11. Dirt and debris is then evacuated from the second compartment by suction force or other evacuation means in the direction of 82a via drainage port 872 for disposal. The degenerated portion of the absorbent material 818 previously in the first compartment (of liquid applicator 860) is now in the second compartment (of negative pressure 82a) having been transformed into a regenerated or restored clean condition ready to become reused by the cleaning head 810 to clean surface 11 once it re-emerges from J8 at direction of arrow 855 to regain contact with the cleaning surface II and the cycle continues.
Preiërably, all drainage ports having force 82a are molded and configured to evacuate waste liquids dirt and debris from the first and second compartments and including the sweeping suction hood are wide enough and configured to suitably maintain an adequate negative pressure of suction force 82a or pumping force or whichever most suitable to evacuate dirt from the passing body of the absorbent material 818 and also on the cleaning surface 11; thercfore, therc may be a valve (not shown) in between evacualion conduits so that for example when vacuuming the surface Ii only without washing it, the gusts of air in.J8 can be switched off at intersection where 872 meets the larger conduit from sweeping hood at fore region of the cleaning device. Since cleaning device 810 may also carry a surface-liquid applicator 836 arranged to apply a cleaning fluid or a rinsing fluid 837 onto surface 11.
Cleaning fluid 837 may be drawn from storage tank M and administered with or without soap as if required. Thus, when necessary, plain or pure water can be used for rinsing the surface prior to passing the absorbent material 818. Cleaning and rinsing fluid may be pumped from source storage tank (NI) or delivered to the outlet of surface-liquid applicator and or to outlet of surface-liquid applicator via gravity once a valve liquid release mechanism is actuated, however, a pump may be utilized instead. Therefore, surface-liquid applicator 836 may also he used for the purpose of indirectly rinsing the surface 11 before the spent liquid mixture is collected by the absorbent material 818; the rinsing liquid 837 acts as a rinsing agent for the absorbent material 818 also. With reference to FIG 87 and FJC 88, like elements such as suction force 82a. waste conduit 872a, guide wheels 891a, wheels 804 and liquid catchment means enclosure module J82 have the equivalent meaning as with those in the above description in this eighth patent embodiment's disclosure.
Referring now to FIG. 93 there is provided a cylindrical absorbent material 91Sf has contact with a cleaning surface 11 and a regeneration means. The absorbent material 91Sf rotates at direction of arrow 954f whilst (when lowered to surface 11) collecting contaminant dirt from a cleaning surface 11 before a suction 9141 placed on 91Sf takes away the contaminants at direction of arrow 82a for disposal to tank K. On the other hand, clean liquid from tank M is delivered via conduit to liquid applicator 960f and 9621 respectively so that the absorbent material 91Sf is rinsed prior to meeting suction 9141. Clean liquid applicator 9621 may rinse the absorbent material 91Sf indirectly thru wetting the surface 11 with clean liquid such as water prior to the absorbent material 9181 collecting said liquid from the surface 11. for example when moving the cleaning device at direction 101.

The absorbent material 918a (class 918b, 918c, 918d, 918e) is fixed to a support structure 919a (class 919k 919c) so that a roller 914a (class 914b, 914c, 914d, 914e) is pressed on the absorbent material 918a (ckiss 918b, 918e, 918d, 918e) rotating at direction 900a (class 900b, 90k) so that liquid and contaminants collected from surface 11 by 9,jSa (class 918b, 918c, 918d, 918e) is removed from 918a (class) and the waste liquid sent lbr disposal to tank K. On the other hand, clean liquid from tank N'! is delivered via conduit to liquid applicator 96% (class 960h, 960c). Clean liquid application on the absorbent material 918a (class) may be done via 960a (class 960b, 960c) and 962a (962b, 962c) so that the absorbent material 918a (class 918b, 918c, 918d, 918e) is rinsed prior to meeting roller 914a (class 9141,, 914c, 914d, 914e). An extension of clean liquid applicator 960a (class 960b, 960c) may rinse the absorbent material 918a (class) indirectly thru wetting the surface 11 with clean liquid such as water prior to the absorbent material 918a (class) collecting said liquid from the surface 11, for example when moving the cleaning device at direction 101.
