Description
- The present invention relates to a floor scrubbing machine.
- More particularly, the present invention relates to a floor scrubbing machine for professional use.
- The so-called floor scrubbing machines "for professional use" (in contrast with machines for household use) are known and widely used for scrubbing floors and surfaces in industrial environments (for example, plants, workshops, laboratories), in commercial environments (for example, supermarkets and department stores), as well as in public buildings (for example, stations, hospitals and the like).
- Such floor scrubbing machines can be of the "walk-behind" type if they are propelled by an operator walking behind the machine or of the "ride-on" type if the machine body includes a seat for the operator.
- In both cases, such floor scrubbing machines generally comprise a body which is mounted on wheels and inside which a supplying tank containing a cleaning liquid (usually a solution of water and a suitable detergent product) and a collection tank for the polluted cleaning liquid after use are provided.
- A motorized rotating brush is mounted in front positon on the lower wall of said body and the supplying tank is connected to said brush by means of a suitable duct: the fresh cleaning liquid is supplied by gravity to the brush, which - by virtue of the combination between the mechanical rotating and rubbing action and the chemical action of the cleaning liquid - removes dirt from the surface with which it comes into contact.
- A rubber squeegee wiping the now dirty cleaning liquid and a suction duct which sucks said dirty cleaning liquid from the squeegee and takes it to the collection tank are also provided, in a rear position relative to the rotating brush, on the lower wall of the machine body.
- Both "walk-behind" machines and "ride-on" machines are further equipped with electrical supply means for operating the rotating brush and the suction system and - possibly - for forward movement thereof.
- Owing to the combined action of the motorized rotating brush, of the rubber squeegee and of the suction duct connected thereto, said floor scrubbing machines allow to leave the floors they are passed on clean and substantially dry.
- Floor scrubbing machines of the known type are, however, subject to remarkable limitations, especially due to their size and poor maneuverability.
- Although on one hand said floor scrubbing machines can be used for cleaning large areas, on the other hand they are not suitable for cleaning narrow and hardly accessible spaces.
- However, it is apparent that in all industrial, commercial and public buildings there are several places that cannot be reached with the floor scrubbing machines of the type described above; an example thereof are the areas around and behind pillars and columns, areas under seats, benches and other fixed furniture and so on.
- Furthermore, the floor scrubbing machines of the type described above are not able to clean the lower part of vertical walls, which often - especially in public buildings - is as dirty as the floors.
- These hardly accessible places are often not cleaned at all, this resulting in a deterioration of the decor and of the cleanliness of the environments.
- Alternatively, in order to clean hardly accessible places, the operator will have to temporarily leave the floor scrubbing machine, equip himself/herself with a bucket and a rag or a mop and manually wash the areas he/she cannot reach with the floor scrubbing machine.
- However, in this manner it will anyway be impossible to obtain a satisfactory cleaning, essentially for two different reasons: first of all, manual rubbing with the rag cannot be as effective as that obtainable with the motorized brush; secondly, the operator will continue to dip the rag in the same bucket, thus using a cleaning liquid becoming dirtier and dirtier.
-
US 4 893 375 discloses a floor scrubbing machine which may operate in two distinct modes: either as a walk-behind floor scrubber or as a manually-operated, scrub-and-recover system using a floor wand having a cleaning solution dispenser and convertible brush/squeegee at the working end of the wand for use in locations with difficult access. - The main object of the present invention is therefore to provide an improved floor scrubbing machine that is able to overcome the limitations of the prior art and, in particular, allows to effectively clean also narrow and hardly accessible places.
