The invention is related to a mobile industrial autonomous device that can be used to perform different functions with the modules (8) of different features which can be easily changed by the user on the same platform. Although the main function targeted with the invention is the cleaning of indoor spaces, functions such as polishing, mowing, fertilizing, spraying etc. can also be provided by the robotic platform of the invention with modules that can be easily changed by the user. It will move automatically by the help of the lidar unit (4) and the camera units on the autonomous device, scan and map the environment and determine a route for itself accordingly and perform its function.

A floor washing-drying machine includes a framework, which can move on the floor and supports, in a lower region, a floor washing assembly having at least one rotating brush and at least one nozzle for dispensing a washing liquid. A floor drying assembly is arranged at the rear of the washing assembly, which includes a rear floor wiper, which extends substantially transversely to the advancement direction of the machine, and a suction device which is connected to a tank for recovering the dirty liquid. The machine further includes at least one pair of lateral floor wipers, which are arranged on mutually opposite sides with respect to the vertical central plane of the framework and extend substantially along at least one portion of the longitudinal extension of the framework; each one of the lateral floor wipers includes respectively at least three vertical drying blades.

The present disclosure discloses that the robot cleaner includes a mop module including a left rotating plate to which a mop is attached to the bottom surface and a right rotating plate to which the mop is attached to the bottom surface; a base on which the mop module is installed; a case disposed to cover at least an upper portion and a part of a side of the base; and a plurality of push supporters supporting the case spaced apart from the base, wherein each push supporter provides the case with the elastic restoring force at least in the upper direction of the base and the outer direction of the base.

A robot cleaner of the present disclosure includes: a main body forming an outer shape; a pair of rotary mops configured to rotate in contact with a floor to move the main body; a drive motor configured to rotate the pair of rotary mops; a mop sensing unit comprising at least one micro switch provided on a surface of the rotating plate configured to output a sensing signal when the mop cloth is attached; and a controller configured to determine attachment state of the mop cloth based on the sensing signal and control the driving of the rotary mop. Accordingly, the robot cleaner may detect whether the mop cloth is attached to the rotating mop, and alert the user, thereby protecting the floor by preventing wet cleaning without the mop.

A mobile cleaner includes a dust housing, an agitator, and a dustpan. The dust housing has a collection opening facing a surface. The agitator is rotatably disposed within the dust housing and is exposed to the surface through the collection opening. The agitator is configured to move foreign material from the floor into the dust housing. The dustpan directs the foreign material moved by the agitator into the dust housing. The dustpan extends around a portion of an outer circumferential surface of the agitator and is configured to rotate independent of the agitator.

A supply unit for a cleaning machine which can be connected via at least one flexible hose, has a heating device for heating water, a water pump for conveying water into or out of the heating device, a hot water and/or steam connector which is connected to the outlet of the heating device, a dirty water tank, a suction device, which preferably includes a suction turbine, for sucking dirty water from a dirty water connector into the dirty water tank. In a preferred embodiment the unit has at least one, preferably precisely one central, drive unit for driving at least one, preferably a plurality of or all components to be driven of the supply unit and/or of a cleaning machine to be connected to it.

A machine (1) for cleaning surfaces (100) comprises a main body (10) and a handle portion (50) configured to move the main body (10) along a determined advancing direction. The main body (10) is equipped with a cleaning brush (15) positioned adjacent to the surface to be cleaned, and a first and a second squeegee element (20a) positioned at opposite sides of the cleaning brush (15). The main body (10) provides, furthermore, a first and a second suction mouth (25a, 25b) positioned at the first and the second squeegee element (20a), respectively, connected to a suction device (30) by a suction circuit (35). This comprises a deviation device (40) configured to alternately and selectively pneumatically connect the first suction mouth (25a), or the second suction mouth (25b) and the suction device (30), and to pneumatically disconnect, instead, the other suction mouth (25a, 25b).

A floor maintenance machine includes a chassis, a floor-cleaning implement adapted for engagement with the floor, and a service cabinet. The floor-cleaning implement is supported by the chassis. The service cabinet is coupled to the chassis and defines a cavity. The cavity receives a plurality of fluid access points collectively therein.

A method for adjusting a position of suction lips of a floor cleaning machine relative to a floor to be cleaned is proposed, wherein a first suction lip and at least one second suction lip located at a distance therefrom, which are arranged on a suction beam, contact the floor, a fan device generates a suction flow which subjects a space between the first suction lip and the second suction lip to a negative pressure, a negative pressure is detected, and the suction flow is adjusted such that the negative pressure lies at a set value or in a set value range, so that an angle of incidence of the first suction lip and the second suction lip on the floor lies at a set value or in a set value range.
