A mobile cleaner includes a body, a mop module, and a sweep module. The mop module includes a pair of spin mops configured to rotate and mop a surface. The sweep module is configured to sweep up foreign material on the surface using a rotating agitator. The sweep module includes a dust housing, the agitator, and a wheel assembly. The wheel assembly is configured to support the dust housing on the surface and includes a wheel body that is movable in a vertical direction. A cliff sensor is configured to detect movement of the wheel body.

The cleaning robot includes a housing, a brush roller and a suction device. The housing is provided with a mounting chamber. A debris collecting chamber is communicated with the mounting chamber. The brush roller is pivotally mounted in the mounting chamber and at least a part of the brush roller protrudes from the mounting chamber. The housing is further provided with a debris collecting channel, one end of the debris collecting channel is communicated with the debris collecting chamber, the other end of the debris collecting channel penetrates through the rear end of housing, and the housing is further provided with a first door for opening or closing the debris collecting channel.

A surface cleaning apparatus having a housing, a suction nozzle, a suction source, a steam port, a steam supply system, and a flexible seal. The housing having a cleaning foot and an upper housing operably coupled to the cleaning foot. The suction source being fluidly connected to the suction nozzle by a working air conduit. The steam port having an aperture provided in the cleaning foot. The steam supply system having a steam nozzle with at least a portion that projects through the steam port. The flexible seal being provided at least around the steam nozzle.

A floor cleaner includes an electrically powered component and a switch. The switch includes a button including an actuator surface. A fluid channel is formed by a fluid collection surface disposed below the button and an outer channel wall extending upwardly from the fluid collection surface, the fluid channel having a fluid outlet. A projection of the button is received in an inner button aperture formed by an inner wall extending from the fluid collection surface forming a bushing around the projection. The inner wall inhibits flow of fluid from the fluid channel through the inner button aperture. The outer channel wall surrounds the aperture wall such that fluid entering the body between the perimeter of the button actuator surface and the aperture wall is collected by the fluid channel and directed to the fluid outlet.

A cleaning robot including: a main body; a drive device; and a cleaning device equipped for wet-cleaning floors to be cleaned, wherein: the main body, on the side facing the floor to be cleaned, is assigned a receptacle unit, a first mop pad configured for wet-cleaning is fastened to the receptacle unit, and the cleaning robot is configured to autonomously exchange the first mop pad fastened to the receptacle unit for a second mop pad.

An auto clean machine comprising: a height computing device; and an obstacle determining device. The height computing device is turned on to compute a height or an overhang height of an obstacle when the obstacle determining device determines the obstacle exists in a predetermined region of the auto clean machine. The height computing device does not compute the height and the overhang height when the obstacle determining device does not determine the obstacle exists in the predetermined region.

A high-power slurry vacuum cart is well suited to collect and contain any slurry or wet residue produced through concrete and other surface processing operations. A multi-horsepower propane engine and propane tank are mounted on a mobile frame, along with a suction pump powered by the propane engine. A slurry containment vessel mounted on the frame has an input in communication with a squeegee and an output coupled to the suction pump. The squeegee may be adapted for floor contact to collect slurry for transfer to the slurry containment tank. The suction pump is directly coupled to the propane engine through a universal joint, thereby obviating the use of belts, chains or pulleys. The output of the pump may optionally be used as an air blower for surface drying, or the like, as well as use as an air blower to assist in emptying the slurry containment tank.

A surface cleaning apparatus is provided with a dispensing system for applying a treating agent stored on the surface cleaning apparatus to the surface to be cleaned. The dispensing system can include at least one container for storing a supply of treating agent and a dispenser for dispensing the treating agent to the surface to be cleaned. The dispensing system uses filtered working exhaust air to blow treating agent off the treating agent dispenser.

Provided is a robot cleaner. The artificial intelligence robot cleaner includes a traveling driving unit configured to allow the artificial intelligence robot cleaner to travel in an indoor space of a home, a cleaning unit configured to remove pollutants, a sensor configured to acquire data that is used to identify a plurality of members, and a processor configured to control the traveling driving unit and the cleaning unit so as to determine one or more subordinate spaces corresponding to each of the plurality of members among a plurality of subordinate spaces by using the data and a map of the indoor space, determine a return time of some or all of the plurality of members, determine a cleaning priority of the plurality of subordinate spaces based on the return time, and perform cleaning according to the cleaning priority.

The present disclosure provides a surface cleaning apparatus that mechanically removes liquid and debris from a brushroll and stores the mechanically-removed liquid and debris onboard the apparatus in a first collection area. The surface cleaning apparatus also collects further liquid and debris from the brushroll by a source of suction including a vacuum motor or a pump and stores the collected liquid and debris onboard the apparatus in a second collection area.
