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.

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.

A fluid dispensing scrubber includes a shaft having a first end and a second end; a fluid inlet configured to receive a first fluid from an external source; a reservoir configured to store a second fluid; a valve assembly configured to selectively mix the first fluid and the second fluid; a scrubbing head supported adjacent the first end of the shaft, the scrubbing head including a brush and a motor operable to rotate the brush; a battery pack supported adjacent the second end, the battery pack operable to provide power to the motor; and a dispensing nozzle configured to selectively dispense one or both of the first fluid and the second fluid, the nozzle supported on an exterior surface of the scrubbing head.

Provided are a vacuum head, a collection bin, a cleaning tray, a filter assembly, and a cleaning apparatus. The cleaning apparatus includes: a housing, a rolling brush, and a cleaning assembly, where the cleaning assembly includes a cleaning medium inlet and a plurality of cleaning medium spray orifices; the plurality of cleaning medium spray orifices face the rolling brush, and lengths of flow channels from various cleaning medium spray orifices to the cleaning medium inlet are equal. According to the present disclosure, a cleaning medium may be sprayed to a rolling brush surface uniformly, so that the rolling brush may be cleaned completely, thereby improving the cleaning efficiency and the cleanliness of the rolling brush.

A method of controlling a moving robot is provided. The method of controlling a moving robot includes the steps of: (a) performing a basic motion of the moving robot which moves on a rotating mop; (b) measuring the slip rate of the moving robot; and (c) controlling the travel of the moving robot.

A cleaner head for a cleaning appliance including an agitator rotatable about an axis; a housing having a front side, a rear side, and first and second sides which extend between the front and rear sides, said housing defining a chamber which at least partially surrounds the agitator, the chamber having a dirty air inlet and a dirty air outlet; and a spray nozzle device for spraying cleaning fluid onto the agitator in a direction towards the rear side of the housing, said spray nozzle device being fluidly connectable to a cleaning fluid supply tank of a cleaning apparatus.

A surface cleaning tool including a housing forming a handle, a motor, a fluid reservoir coupled to the motor for rotational movement, a cleaning head coupled to and rotatable with the fluid reservoir, and a valve configured to control the flow of fluid from the fluid reservoir to the cleaning head. The valve is actuated by movement of the fluid reservoir from a first position to a second position relative to the cleaning head.

A cleaner includes a body, a left spin-mop module and a right spin-mop module configured to perform mopping, and a water supply module configured to supply water to the left spin-mop module and the right spin-mop module. The water supply module includes a water tank to store water therein, a pump to pressurize the water in the water tank to move the water to the left spin-mop module and the right spin-mop module, a first supply pipe connecting the water tank and the pump, a common pipe connected to the pump, the common pump configured to guide movement of the pressurized water from the pump, a first branch pipe configured to guide a first portion of the water in the common pipe to the left spin-mop module, and a second branch pipe configured to guide a second portion of the water in the common pipe to the right spin-mop module.

A surface treatment robot includes a chassis having forward and rear ends and a drive system carried by the chassis. The drive system includes right and left driven wheels and is configured to maneuver the robot over a cleaning surface. The robot includes a vacuum assembly, a collection volume, a supply volume, an applicator, and a wetting element, each carried by the chassis. The wetting element engages the cleaning surface to distribute a cleaning liquid applied to the surface by the applicator. The wetting element distributes the cleaning liquid along at least a portion of the cleaning surface when the robot is driven in a forward direction. The wetting element is arranged substantially forward of a transverse axis defined by the right and left driven wheels, and the wetting element slidably supports at least about ten percent of the mass of the robot above the cleaning surface.

A robot cleaner enables a wet cleaning, has a replaceable cleaning unit, and ensures a sufficient friction force for doing a wet cleaning of a floor. The robot cleaner includes a frame including a wheel for driving, a replaceable cleaning unit formed at a lower part of the frame to clean a bottom surface and disposed in front of the wheel, a tank disposed at an upper part of the wheel and configured to supply fluid to the cleaning unit, a pump configured to pump the fluid contained in the tank such that the fluid contained in the tank is supplied to the cleaning unit, a hose configured to extend to the pump and the upper part of the cleaning unit and through which the fluid pumped by the pump flows, and a bumper formed on a side of the frame.
