A water supply mechanism and an automatic cleaning apparatus are provided. The water supply mechanism is applicable for a wet cleaning assembly of a cleaning device, comprising a water outlet device, wherein the water outlet device is connected to a cleaning liquid outlet of a water tank, and a cleaning liquid in the water tank flows to the water outlet device through the cleaning liquid outlet of the water tank and is transported to a surface to be cleaned through the water outlet device.

A roller cover for a floor-cleaning machine with a housing, a cleaning roller, a drive, a dirt container, and a dirt strip. The housing having a rear wall and defining an opening that faces a floor surface during operation of the roller cover. The cleaning roller includes a cleaning element that extends through the opening. The drive rotationally powers the cleaning roller such that the cleaning roller rotates toward the rear wall. The dirt container is disposed in the housing and faces away from the rear wall. The dirt strip has a bottom edge that is arranged on that side of a longitudinal axis of the cleaning roller that faces the rear wall and configured to engage a surface of a floor. The dirt strip is movably coupled to the housing to permit changes in the distance between the bottom edge and the longitudinal axis.

A detachable structure and a self-moving robot are provided. The detachable structure is provided in a self-moving robot including a wet cleaning apparatus. The wet cleaning apparatus includes a housing and a cleaning assembly disposed in the housing, and the detachable structure includes: a pressure plate having a connection end and a movable end. The movable end is adjustably clamped to the housing. When the movable end and the housing are in a clamped state, the movable end blocks a partial structure of the cleaning assembly such that the cleaning assembly abuts against the housing; and when the movable end and the housing are in a non-clamped state, the cleaning assembly is removable from the housing.

Systems and method for self-cleaning extraction cleaners, including upright or robot extraction cleaner are provided. In one system, a tray can be provided for docking the extraction cleaner during the self-cleaning mode. The tray may include one or more sprayers for spraying a cleaning fluid toward an agitator of the extraction cleaner. In another system, a nozzle flushing manifold mounted on the nozzle assembly of the extraction cleaner includes a plurality of distributor outlets configured to spray cleaning fluid into the suction pathway.

A combination of a floor cleaner and a cleaning tray. At least a portion of a base of the floor cleaner is received by a reservoir of the cleaning tray. The floor cleaner further including an upright portion movable between an inclined use position and an upright storage position. The brushroll is powered by a brushroll motor. The brushroll motor includes a control circuit that controls the brushroll. The control circuit has a first switch that is open when the floor cleaner is in the upright position and closed when the floor cleaner is in the inclined use position. The second switch is in parallel with the first switch. The second switch is opened in response to the portion of the base being removed from the cleaning tray and the second switch is closed when the portion of the base is in the cleaning tray.

A stand-on floor scrubber is provided to clean floor surfaces and includes a housing, a scrubber head, and drive wheels. The scrubber head may be positioned against a floor to provide scrubbing action during a floor cleaning operation. The housing includes an upright forward housing section and an upright rear housing section that are spaced apart by an operator platform with each of the forward housing section and rear housing section containing operational components of the stand-on floor scrubber, such as batteries and fluid tanks. The operator platform is sloped between the forward and rear housing and provides adjustable support for an operator of the stand-on floor scrubber.
