Description

The present invention relates to an improved mop for wet cleaning. More precisely, the present invention is directed to creating a mop for wet cleaning, including a washing device and a vacuum device for collecting dirty water from the floor, in order to obtain a clean and substantially dry floor surface.

Mops for cleaning floor surfaces usually include an absorbent mop or sponge and some kind of squeezing mechanism for squeezing dirty water from a mop or sponge. In particular, a mop is used in combination with a bucket of washing liquid, usually consisting of water with a washing additive. The mop absorbs the cleaning fluid that is used to clean the floor. When the mop becomes contaminated during the floor cleaning process, it is placed back into the bucket to rinse the mop and soak up additional washing liquid. The constant immersion of a dirty mop into a clean liquid in a bucket quickly contaminates the clean liquid in a bucket and reduces the effectiveness of washing during subsequent use of the mop. Thus, it would be advisable to prevent contamination of the washing liquid during the floor washing. In addition, it would be advisable to avoid approximately 15 minutes drying the floor when washing with a conventional mop with a bucket.

Suction brushes (rollers) have been proposed to remove moisture, which remove the washing liquid from the surface of the washed floor. One such suction device is described in US Pat. No. 5,067,199. However, this suction device does not eliminate the problem of contaminating clean water in a bucket, because a conventional mop and bucket must be used before using the suction device. In addition, this suction device has the disadvantage that it requires three or four separate devices to perform the washing operation, including a suction roller or brush, a mop, a mechanism for squeezing dirty water from a mop and a bucket.

A different suction washer is known that provides a combined cleaning and water intake device for washing and drying the floor surface. This device includes a tank for clean and dirty water, having a flexible partition that separates clean and dirty water in the tank. Clean water is metered from the tank, and for cleaning a cleaning nozzle is used, including bristles or hard brushes. After cleaning, the suction system is activated to remove dirty water from the floor, and dirty water is collected in the tank.

Examples of the layout of cleaning and water intake devices are described in US Pat. Nos. 2,886,764, 3,020,576, 3,040,362, 3,040,363, and 3,060,484. The devices described in these patents have several drawbacks, including cumbersome size and heavy device weight, the need for a power cord that interferes with user, and safety considerations associated with the presence of the necessary voltage in a device filled with water.

The device according to the present invention eliminates the disadvantages of the prior art by providing a fully autonomous, not having a power cord mop for wet cleaning, combining cleaning and drying in one device, and leaving the floor essentially dry.

According to a further aspect of the present invention, a suction washing device for washing surfaces includes a washing device body, a handle connected to the body, an absorbing washing element mounted on the body and movable between an extended position in which the washing element extends out of the body and is used for washing surface, and a retracted position, in which the washing element is essentially retracted into the housing, the suction motor inside the housing, designed to remove contaminants ennoy liquid surface, the reservoir is mounted on the housing for collecting contaminated liquid removed from the surface by the suction motor, and a battery power supply, supplies power to the suction motor.

According to a further aspect of the present invention, a suction washing device for cleaning surfaces includes a washing device housing, a retractable sponge mounted on the housing and having the ability to move between the extended position and the retracted position, a backward mechanism for moving the sponge between the extended and retracted positions, suction system to remove and collect contaminated liquid from the surface to be cleaned, and a switch to actuate the suction system Nia under the influence, in which the retraction mechanism back suction system is activated when the sponge is in the retracted position, and the suction system is switched off, when the sponge is in the extended position.

In accordance with another aspect of the invention, an autonomous cleaning system for mops and drying for floors includes a housing, a handle connected to the housing, an absorbing washing element mounted on the housing, a pair of scrapers (brushes) mounted on the housing to collect contaminated liquid on the floor surface , a suction system inside the housing to remove contaminated liquid from the floor surface, collected by a pair of scrapers, in which the suction system leaves the floor essentially dry, the reservoir mounted on the housing for collection is dirty liquid removed from the floor when the suction motor is running and the battery pack is installed in the housing and provides power to the suction system.

According to a further aspect of the invention, the washing device includes a washing device case, a handle connected to the case, a sponge mounted on the case and movable between an extended position in which the sponge extends from the case and is used for washing the surface, and a retracted position in which the sponge is essentially retracts into the body, while the sponge has a central plane, dividing the sponge in half, a pair of scrapers installed on the body and located in parallel at a distance from one another, while the pair with Rebko located in first and second planes, and wherein the central plane of the jaw diverges from the first and second scrapers planes in a direction away from the housing.

One advantage of the washing device is that one stand-alone device performs the metered flow of the fluid, washing and drying.

Another advantage of the washing device is that contamination of the washing liquid is prevented by providing separate tanks for clean water and dirty water.

An additional advantage of the washing device is the compact size and light weight of the device.

Other advantages and advantageous aspects of the invention will become clear to those skilled in the art after they have read and delved into the subsequent detailed description of the invention.

Referring now to the drawings, which are given solely for the purpose of depicting preferred embodiments of the present invention, but not with a view to limiting its essence, a mop device for wet cleaning with a vacuum system without a power cord is shown in FIG. 1-5. The device mainly includes a handle assembly 1 0 connected to the housing 1 2, a removable cylinder 1 4 for clean water and a removable tank 1 6 for dirty water. The washing device is installed in the housing 1 2 and includes a retractable sponge 18, a pair of scrapers 20, battery pack 22, a suction motor 24, a suction fan 26, and a switch 30 for turning the suction motor on and off. The clean water cylinder 14 includes a piston 28 for dispensing clean water along with a cleaning solution to the floor. The sponge 18 extends out of the housing 1 2 when it is used to clean the floor, and then retracts back into the housing during the suction operation. Pulling the sponge 18 into the housing drives the suction motor 24, and the suction system begins to draw water from the floor into the dirty water tank 16. The scrapers 20 shown in FIG. 3 and 4 are lowered to the floor during the suction operation to collect dirty water and leave the floor essentially dry.

The handle assembly 10 includes an upper handle 40 with a portion of a hand grip 42 covered with foam and a cap 44. The cap 44 is preferably provided with a hinge device that is used to hang the device on the wall. The upper handle 40 includes a threaded insert 46 that allows the upper handle to be screwed onto the lower handle 48, which is a one-piece piece fixed in the housing 12 with at least two bolts 50. The handle 48, which is a one-piece piece, is preferably molded from plastic and contains a thread section for connection to a threaded insert 46, a support for the spin handle 52 and means for mounting the lower handle 48 on the housing 1 2.

The spin handle 52 is pivotally mounted on the lower handle 48 in the first hinge 54 and hinged on the rod 56 in the second hinge 58. The extraction handle 52 is made with two legs 60, one of which goes around each side of the lower handle 48. The flat end of the rod 56 is inserted between two uprights 60 and pivotally attached to the uprights axis passing through the bar and the rack. The rod 56 passes near the lower handle 48, through the housing 12. The opposite end of the rod 56 passes through the metal bracket 64 and is attached to the sponge 18.

In operation, the spin handle 52 extends and retracts the sponge 1 8 and simultaneously switches the suction motor 24 on and off via the switch 30. The spin handle 52 moves the sponge 1 8 between three positions. In the extended position shown in FIG. 1, the sponge 18 extends in the shape of a fan for a pair of rollers 62 mounted on an extraction bracket 74. In the extended position, the metal bracket 64 rests against the rollers 62 and holds the sponge in the position required for washing. In order to remove the sponge 18, the spin handle 52 is retracted from the upper handle 40 in the direction of the arrow A. When the spin handle is moved, the rod 56 causes the sponge to pull up. When lifting the sponge, the water absorbed by the sponge is squeezed onto the floor by compressing the sponge between the rollers 62.

The position in which the sponge 1 8 is retracted (removed) is shown in FIG. 2. In this position, the sponge 1 8 is inserted into the metal bracket 64 and the front end of the sponge extends only a small distance beyond the ends of the rollers 62. This distance is preferably in the range from 0.1 to 0.5 inch. The sponge 18 is held in the retracted position by expanding a part of the sponge behind the rollers 62. In addition, in the handle 52, clamps (not shown) can be provided to hold the sponge in the retracted position.

Spin handle 52 is also used to remove sponge 1 8 for replacement or cleaning. Removing the sponge 1 8 is performed by pressing the handle 52 in the direction towards the upper handle 40 in the direction indicated by arrow B. As a result, the sponge 1 8 and the metal bracket 64 pass through rollers 62, which diverge in the extraction bracket 74.

The spin handle 52 also turns the suction motor 24 on and off by actuating the switch 30 using the raised deflection 66 in the rod 56. Thus, the suction motor 24 only works when the sponge 1 8 has been removed. This allows you to save battery power by stopping the motor when it is not needed, giving you the opportunity to save battery pack energy. As shown in FIG. 2, when the sponge is retracted to a retracted position, the projecting deflection 66 in the rod 56 passes over the switch 30, including the suction motor 24.

Basically, a battery pack of 22 power with a voltage of 6 V, having 5 elements, provides from 5 to 1 0 min of operating mode for a permanent magnet electric motor and with a current of 1 2-1 4 A. Since the suction motor 24 only works when required suction, battery pack power supply 22 can be used for a floor having a size of at least 250 square feet (23 m ² ) without recharging.

The battery pack of power supply 22 is shown more clearly in FIG. 5, which is an enlargement of the central part of FIG. one . The battery pack of power supply 22 is preferably a pack of rechargeable 6-volt batteries capable of holding up to six cells, which is inserted into the cavity 68 for the battery inside the housing 1 2. The battery pack of the power battery is held in place by a locking (locking) cell 70 that rotates around the bottom handles 48. The protrusions 72 on the lower handle hold the locking element 70 in the proper axial position on the handle. The locking element 70 is shown in the open and closed positions in FIG. 1 and 2, respectively.

When the battery pack 22 enters with a slide into the battery cavity 68, the two spring-loaded battery contacts 80 move to a position in which the battery contacts 80 in the battery cavity come into contact with the mating battery contacts 78 on the side of the battery pack.

A suction motor 24 is installed inside the device 82 for mounting the motor in the usual way, for example by mounting the motor in a pair of 12 supports formed inside the housing. The suction motor 24 is preferably a permanent magnet motor, of direct current, about 12-14 A, 6 V (strontium magnet), with a power of about 18,000 to 25,000 rpm, preferably from 21,000 to 22,000 rpm. The suction motor 24 is isolated from the adjacent fan chamber 84 by an elastic sealing gasket 86 shown in FIG. 5, which prevents the passage of any amount of water that can get into the fan chamber, into the electric motor.

The suction motor 24 used in the present invention is capable of self-cooling and does not require a fan for cooling. However, if necessary, it can be added. The ventilation holes 88 are preferably provided on the side of the housing 1 2 to ensure air circulation closer to the motor. The chamber of the fan 84 also includes outlets 90 through which the exhaust gas passes.

The lower part of the body is best shown in an enlarged view of FIG. 4 and includes a sponge, a squeegee magazine (pallet) 92, a dirty water tank 16, a fan chamber 84 and a suction fan 26.

Store 92 for scrapers includes two elongated scrapers 20, which are inserted into the store 92 in a known manner. Scrapers have a length of from 5 to 20 inches, preferably from 8 to 12 inches (20.32-30.48 cm). The scraper magazine 92 has a suction inlet 94, which is an elongated oval opening located between the two scrapers 20 and extending along 1/4 to 1/2 of the entire length of the scrapers in the center of the scrapers. Water is sucked up along the length of the scrapers 20 from the open ends between the scrapers into the suction inlet 94. The cross-sectional area of the passage between the two scrapers and the floor and the cross-sectional area of the suction inlet 94 are sized to provide the necessary air velocity that should carry the water droplets with air. At speeds of approximately 1,000 feet (304 m) per minute to approximately 3,000 feet (914 m) per minute or higher, water droplets will be carried along with the air.

The scrapers store 92 is fitted with a set of wheels 1 22 to enable the entire device to easily move on wheels on the floor during washing, suction or transportation. The scrapers 20 are installed in the scrap shop 92 in parallel such that when the device rolls along the floor, both scrapers are in contact with the floor. When the sponge 1 8 is in a stretched position, the scrapers 20 will not be in contact with the floor, as the sponge extends beyond the scrapers. The central plane X, which halves the sponge 18, is located at an angle α relative to the Y planes of the scrapers. This angle α is in the range of about 10 to 30 °, preferably about 25 °.

The upper surface of the scraping box 92 includes an oval groove 96 surrounding the suction inlet 94. To ensure tightness between the suction inlet 94 and the central tube 1 00 of the dirty water tank 1 6, an elastic sealing element 98 is placed in the groove 96. Elastic elastic element 98 it is preferably made of a compressible spongy rubber material, which spring up the reservoir 1 6 upwards so that it becomes in the desired position after its installation in the housing 1 2.

Each scraper 20 is made with a smooth edge on one side and a notched edge on the opposite side. The scrapers are installed inside the magazine 92 in such a way that the smooth sides of the two scrapers face one another. Thus, when the device moves along the floor, both scraper are in contact with the floor and bend. Water first passes under the first scraper due to the fact that the jagged edge of the scraper is in contact with the floor. This water will then be retained by a second scraper, the smooth edge of which is in contact with the floor. Thus, the device can be used alternately both in the forward and backward directions when the user is processing the floor surface. Water is drawn from the space between the scrapers by a stream of air from the open ends between the scrapers to the central suction inlet 94.

From the central suction inlet 94, the water enters the dirty water tank 16 containing the central tube 1 00, which is molded in the tank. The central tube 1 00 passes a sufficiently large distance up into the tank 1 6, which makes it possible to dispense with the closure element closing the central tube to avoid leaks when the tank is removed to remove water. The lid 1 02 is located inside the upper part of the tank 1 6 and is sealed at the edges of the tank with an O-ring 104. The lid 1 02 contains a hole 1 06 through which air passes from the tank 1 6 to the fan chamber 84. The lid 102 also includes a guide wall 1 08 to deflect water that is sucked through the central tube 1 00 into the tank. A mechanical seal 116 is provided in the lid 1 02 around the hole 1 06 to tightly close the passage between the dirty water tank 16 and the fan chamber 84.

The central tube 100 and the baffle 108 are located inside the dirty water tank 16 so that a large tank capacity can be provided in an inclined working position. In addition, if the device is placed on the floor and the back surface 118 of the device is located on the floor, with a partially filled tank of 1 6 for dirty water, the dirty water will not flow out either through the central tube 100 or through the hole 106 into the fan chamber 84.

The dirty water tank 16 and the lid assembly 102 are removed from the housing 12 for emptying and cleaning. The tank 1 6 is inserted by installing the bottom of the tank against the sealing element 98 and moving the tank forward into the housing. As soon as the tank 1 6 is inserted, it is secured with a bolt 110, which is slidably mounted outside the tank and has a protrusion 112 that enters the corresponding recess 114 in the housing 1 2. The lid 1 02 of the tank 1 6 for dirty water may also have one or more locking means 120, which hold the reservoir in the housing at the same time as the shutter 110.

The suction system in operation sucks air from the open ends between the two scrapers 20 through the suction inlet 94 and the central tube 100 of the dirty water tank 16 at a rate that allows you to entrain water droplets in the air. The water hits the guide wall 1 08 inside the tank 1 6 and is directed down into the tank. The air velocity decreases when it enters the tank 1 6 from the central tube 1 00 and drops of water fall into the tank. Then, the air goes around both sides of the central tube 1 00 and exits the tank through the hole 1 06 into the chamber of the fan 84 through the suction fan 26, and then from the casing through the vent holes 90. To maintain this drop in speed in the tank 1 6 at which water drops fall out from the air into the tank, the cross-sectional area of the air passage through the tank between the guide wall 1 08 and the hole 1 06 must exceed the cross-sectional area of the central tube 100. While the air velocity in the tank is mental Approximately less than 1000 feet (304 m) per minute, water will remain in the tank.

The dirty water tank 1 6 may also include control means that turns off suction when the water in the tank 1 6 reaches a certain level. This tool may include a floating device that blocks the opening 1 06 of the tank 1 6 when it is full. Alternatively, the motor used can provide automatic shutdown. For example, a motor with 9 inches (22.86 cm) of hermetic suction will automatically shut off when the tank is full to 9 inches (22.86 cm).

The cleaning solution is supplied to the floor surface before washing with a cylinder of 1 4 for clean water, which is removably mounted on the front surface of the 1 24 housing. The washing solution or washing liquid that is used in the cylinder for pure water according to the present invention may be any known washing solution or combination of solutions, for example water with the addition of detergent.

The container 14 is preferably a blow molded bottle having three holes and a piston 28 which is actuated in order to allow the washing solution to flow onto the floor. The first hole 134 is provided on the side surface of the container and has a threaded cap 1 40 that is removed to fill the container. Since the first opening 134 is located on the side of the bottle, the bottle can be easily filled in the sink. The cap 1 40 can be used as a measuring device in order to measure the required amount of detergent additive that is miscible with water in the bottle.

The second bore 136 is provided with a dispensing dispensing cap 1 42 with a thread having an opening 1 48 for dispensing and a supporting surface of the piston or a seal 1 44 surrounding the opening for dispensing, against which the end of the piston is hermetically sealed. The third hole 138 serves to receive the piston 28 and provides an air channel. The presence of three holes in the cylinder 1 4 allows you to fill the cylinder without removing the piston 28 from the cylinder.

The piston 28 has a handle 1 46 shown in FIG. 1, at the first end 1 4, and the second end passes through the third opening 138 in the cylinder 1 4 for contacting the piston bearing surface 1 44 and closing the dispensing opening 1 48. Spring 150, best shown in FIG. 5, acts between the ring 152 on the piston 132 and the bottom surface 154 of the piston cap 156 to spring the piston to the closed position.

The piston cap 156 includes a cylindrical part 158 that extends into the neck of the opening 138 in the cylinder 14 and provides a ventilation mechanism for removing air from the cylinder when the piston handle 1 46 is drawn in the direction of arrow C. which provides a ventilation mechanism. The first O-ring 1 60, located in the annular support surface 1 66 on the piston, provides a hermetic seal between the piston 28 and the cap of the piston 156 in the closed position. However, when the piston handle 146 moves up in the direction of arrow C, opening the dispensing opening 148, the first O-ring 160 slides up above the groove 162 and allows air to pass through the cap into the bottle. The second O-ring 1 64 provides a tight seal between the piston cap 156 and the balloon 14.

The balloon 14 is mounted on the housing 12 by means of a pair of housing pins 170 which extend upward and are inserted into the mating grooves 1 72 in the balloon, sliding the balloon downward on the pins, as shown in FIG. 3A. The canister 14 is then fixed in place by a pivoting latch 1 74, which snaps over the ledge 1 76 at the top of the can.

The clean water cylinder 1 4 is designed to contain a quantity of washing liquid sufficient to clean the floor with a surface area of at least 250 square feet (23 m ² ), preferably with a surface area of 250 to 300 square feet (23-28 m ² ). In addition, the container 14 for clean water preferably has a volume slightly smaller than the volume of the tank 16 for dirty water. This allows the tank 16 for dirty water to collect as spilled liquid, and the entire contents of the cylinder 14 for clean water. For example, a cylinder 1 4 for clean water may have a capacity of approximately 16 ounces (450 g), while a tank for dirty water has a capacity of about 24 ounces (680 g). Preferably the volume of the tank 1 6 more than the volume of the cylinder 14 by approximately 20-60%.

Despite the fact that the containers for clean water and dirty water were called the cylinder 14 and the tank 16, respectively, it should be understood that these terms refer to any type of container for liquid. These containers are preferably made of a lightweight, wear-resistant and slightly flexible material, such as plastic.

The first embodiment of the present invention includes a retractable sponge and a fixed pair of scrapers. However, it should be understood that a fixed sponge and moving scrapers can be used.

FIG. 6A and 6B depict an alternative implementation example of the washing device 200, in which the sponge 202 and the scrapers 204 are in a fixed position at the bottom (bottom) of the washing device. This embodiment is used to clean the floor in the position shown in FIG. 6A, where the sponge 202 is in contact with the floor. Washing fluid can spill on the floor as the handle 206 is pushed up and down before or during the floor washing. When the wash is completed, the device 200 switches to the position shown in FIG. 6B, so that the scrapers 204 are in contact with the floor and the floor can be dried in the same manner as described for the first embodiment.

The implementation example of FIG. 7A-7C is a washing device 300, also having a fixed sponge 302 and fixed scrapers 304, which is switched between the arrangements shown in FIG. 7A and 7C for washing and drying operations. This embodiment also includes an additional flush pad 306, which is located at one end of the device 300 and is used for flushing in the position shown in FIG. 7B. Wash pad 306 can be removably mounted using a VeLcro device. The washing device 300 also includes a telescopic handle 308.

A fourth embodiment of the washing device 400 is shown in FIG. 8A and 8B. The washing device 400 includes a retractable sponge 402 and fixed scrapers 404. The washing liquid is supplied through the opening 406 for the dosed supply of washing liquid, which is located at the top of the device 400, and the pump handle 408 is used to supply the pressurized fluid so that it can be sprayed out of the hole.

In the exemplary embodiment of the washing device 500 shown in FIG. 9, the clean water tank 502 and the dirty water tank 504 are mounted side by side on the device. In addition, the sponge 506 is made so that it surrounds the scrapers 508.

Finally, the washing device 600 of FIG. 1.0 has a removable dispensing bottle 602 mounted in slot 604 in the housing of the washing device. This dispensing bottle 602 has a spray nozzle 606 for spraying cleaning fluid on the floor surface.

FIG. 11-1 6 show a preferred implementation example of a scrapers magazine 92, which provides a regulating mechanism for adjusting the position of two scrapers 20 relative to each other, which makes it possible to use the device for a larger range of washing angles compared to the capabilities of the fixed scrapers.

The three-dimensional image with the spatial separation of parts from the bottom of the scrapers' store 92 and one of the two scrapers 20a is shown in FIG. 11. The scraper magazine 92 has springs 700, which are inserted into the magazine and allow the front scraper 20a to move in the direction of arrow D in order to provide different washing angles.

The scraper magazine 92 has a front wall 702, a rear wall 704, an upper wall 706, two end walls 708, 710, and several central partition elements 716. Each of the scraper 20a, 20b includes a flexible scraper blade 712 made of rubber or other elastic material, inserted into the U13 shaped housing 714 scrapers. The front scraper 20a is inserted into the scraper magazine 92 near the front wall 702, while the rear scraper 20b (shown in FIG. 12) is inserted into the scraper magazine near the rear wall 704. The scraper 20a and 20b are mounted in the scraper magazine 92 between the center partition elements 716 and the front or rear walls of the magazine for scrapers with two tabs 718 located on the inner surface of each of the walls (front and rear). The tabs 718 are inserted into the corresponding slots 720 in the housing 71 4 scrapers.

The slits 720 are most clearly visible in FIG. 1 2, which depicts a top view in perspective of the scraper magazine 92, with the front wall 702 removed. The slits 720 are of such size that the scraper 20a can be moved from the extended position shown in FIG. 1 2-1 4, in the retracted position of FIG. 15 and 16, in which the springs 700 are compressed.

As shown in FIG. 12A, springs 700 are preferably lamellar springs having a base 722, two side portions 724, 726, and one leg 728. The side portions 724, 726 of each spring 700 engage with the ends of a square hole 730 (Fig. 12) in the upper wall 706 of the magazine 92 for scrapers. The concave side portions of the leaf spring 724, 726 allow the spring to be forcefully inserted into the square hole 730 and held there. The end of the spring leg 728 engages with the upper surface of the scraper body 714 and spring up the scraper 20a in the direction from the upper wall 706 of the scraper magazine.

As shown in FIG. 13, when the front scraper 20a is in the extended position, it extends beyond the rear scraper 20b by a distance d, which is preferably from 0.1 to 0.5 inch (0.25-1.27 cm), more preferably about 0, 2 inches (0.5 cm). According to one embodiment, the rear scraper 20b is fixed, and the front scraper 20a is movable. The movable front scraper 20a increases the range of angles at which the washing device can operate, by about 10 / -40 / compared to the washing device in which both the scraper are fixed. According to another exemplary embodiment of the invention, both the front scraper 20a and the rear scraper 20b can be movable to increase regulation. According to another alternative embodiment, the rear scraper 20b can be movable and the front scraper fixed.

According to one preferred embodiment of the present invention, the springs 700 are plate springs made of a beryllium-copper alloy that has undergone a heat treatment. Various spring coatings, such as nickel, can be used for corrosion resistance. Of course, the springs can also be made of plastic for corrosion resistance. Although lamellar springs are shown, any other type of compression spring can also be used, including coil springs.

When shop for scrapers FIG. 11-1 6 is mounted on a wet cleaning mop that does not have a power cord, as shown in FIG. 1 4, permissible washing angles, i.e. the angle between the handle 40 and the floor, under which the mop can be held while the scrapers are working, increases significantly. This allows users to mop at different heights with a wide range of corners of the sink, not allowing the front scraper 20a or rear scraper 20b to lose contact with the floor and leave water strips on the floor.

The advantages of each of the embodiments of the present invention include the fact that this device is an autonomous device that contains clean water and there is no need to carry a heavy bucket of water. In addition, the problem of pollution of clean water is eliminated and the floor remains really dry. The device is easy to clean, because after removing the dirty water tank, any obstacle in the suction system can be easily seen and removed.

Although the invention has been described in detail with reference to preferred examples of its implementation, it will become clear to a person skilled in the art that various changes and equivalent solutions are possible without departing from the gist and scope of the present invention.
