OBJECT OF THE INVENTION

The present invention refers to a machine or mobile equipment for manually cleaning stairways, floors, and baseboards regardless of the surface material or coating of the surface (metallic surfaces, granite flooring, clay, marble and concrete), for residential premises.

BACKGROUND OF THE INVENTION

The purpose of cleaning a certain area is to provide a safe environment, free of dust and waste, as well as to reduce the amount of microorganisms that may be present in said area. Cleaning includes removal of microorganisms and chemical substances which are present in the surfaces, by mopping and washing with water, soap or a suitable detergent, so as to remove residues, dust and impurities from the surfaces.

In order to achieve these objectives, several cleaning methodologies have been created, as well as manual and automated equipment for different types of surfaces and several products intended therefor.

Each day there are created new products and devices which make cleaning tasks of different areas easier, especially in people homes.

Patent No. US 8,938,850 B1 granted to Velez discloses a device for cleaning stairways having a vacuum system which allows automatically vacuuming dirt. This mechanism features a pair of vacuum units coupled to each other by means of a connector. Each vacuum unit comprises its own vacuum housing extending through a bottom surface of the vacuum housing. A set of side rollers is coupled to the vacuum housing for moving the device. The movement is performed in a forward direction and then, by means of the movement system of the machine, a second movement is performed transversely to the first direction. Patent No. 8,376, 124 B1 granted to Rosen, discloses a manual cleaning system which uses an elongated brushes system as the main cleaning process. This mechanism operates as follows: This machine comprises a set of bristles extending along a longitudinal axis which are intended for surface cleaning. This happens due to the existing pulley process. This pulley process uses a set of resilient tensionable belts actuating the drive motor.

Patent No. US 8,337,625 B2 granted to Gehm discloses a system for cleaning escalators which is formed by a set of parallel bands using a cleaning material to gather dirt from the moving step. These bands are formed by a set of cleaning pads which are attached to a rotating brushes cleaning system.

Patent No. US 6,527,103 B2 granted to Neszmerak, discloses a system for cleaning escalators which allows waste to accumulate in a waste collecting plate.

Patent No. US 5,715,565 granted to Kern, discloses a system for cleaning escalators which is formed by a set of elements such as:

- A roller brush rotationally driven being integrated in the housing.

- A device for adding a solution to the cleaner.

- A suctioning device for removing dirt particles.

- A brush moving in the escalator moving direction.

The roll brush moves rotationally, such that dirt is removed as the adding device adds to the cleaning device the solution which is used for removing dirt residues in the area, and while the suction device removes the exceeding dirt particles, the brush moving in the escalator direction finishes the cleaning process.

Patent No. US 5,042,641 A granted to Soldat, discloses a machine for cleaning moving escalators, this system comprising a set of grooves, cleaning the escalators as people walk on them, and a brush. Bristles perform a counter-movement to that of the brush, in such a way that the surface is cleaned twice at practically all the step height. Patent No. US 8,689,392 B2 granted to Kawamura, discloses a vacuum cleaner for cleaning dust and dirt in a given surface. This machine prevents dust form being dispersed during the vacuuming process, since the mechanisms from the state of the art before this invention, did not contemplate an improvement of this drawback.

Patent number US 7,979,959 B2 granted to Courtney, is an accessory for a cleaning device which comprises a head, and a suction opening downward oriented. The rotating mechanism provides a movement between the head and the opening which allows a rotation that cleans the surface.

Patent number US 7,401 ,378 B2 granted to Hobbs, consists of a vacuum apparatus having a vacuum pump mechanism for courtyards. The vacuum pump mechanism is adapted for any type of cleaning, such as it is the case of debris removal, and this is achieved by adapting different attachments, depending on the type of cleaning or the courtyard area intended to be cleaned.

Patent number US 7,284,297 B2 granted to Shanor, discloses a support for the current mechanisms for cleaning floors. DESCRIPTION

The main object of the present invention is to make the domestic cleaning and disinfection tasks from every home area easier, in a quick and efficient way, by providing a device formed by a rectangular base made of plastic or the like, in which the components are to be accommodated. At the bottom side thereof, there are a number of outlets for water steam being arranged in line, with rotating brushes being coupled to the steam outlets, these brushes being rotational and replaceable so as to adapt them according to the type of surface to be treated, an replaceable sponge and mop being also replaceable for washing thereof). All the attachments cited can be replaced once the service life thereof is finished.

Another object of the present invention is to avoid dependence on the electric power supply using a rechargeable battery by means of system having electrical connection. It is another object of the present invention the activation of the system by means of an on-off button.

Another object of the present invention is to handle the device by means of a retractable stick located on a rotational base for a more comfortable directional control thereof by the user.

It is another object of the present invention to produce water steam being contained in a small inner storage deposit.

It is another object of the present invention to proceed with the cleaning of baseboards by means of a folding plate being provided with outlets for the water steam, as well as with a sponge and a mop. Another object of the present invention is to protect the baseboard cleaner by applying a removable protecting cover when not in use.

It is another object of the present invention to provide the equipment with mobility by means of four multidirectional wheels which allow a better displacement of said equipment.

It is another object of the present invention to prevent the wheels from contaminating the surface by means of small mops covering them and thus preventing the wheels footprint from being marked on the clean surface.
