A cleaning tray is provided for docking an extraction cleaner, including upright or robot extraction cleaners, for self-cleaning. The cleaning tray may include one or more sprayers for spraying a cleaning fluid toward a suction nozzle, brush chamber, and/or agitator of the extraction cleaner. Systems for self-cleaning extraction cleaners are also provided.

The present disclosure discloses an automated cleaning robot which includes a robot body capable of realizing automatic walking and a mop mechanism provided at a rear end of the robot body. The mop mechanism includes a mount support rotatably connected to the robot body, a rotation component received in and rotatably connected to the mount support, a crawler-type wiping cloth sleeving outside the rotation component, and a lifting mechanism being in transmission connection with the mount support, for driving a rear end of the mount support to ascend or descend relative to a front end of the mount support.

A handheld cleaning device includes a surface-moving portion and an upright portion. The surface-moving portion is in contact with a surface to be cleaned and is connected with the upright portion. The upright portion is configured to move the surface-moving portion in a case in which the surface-moving portion is in operation. The handheld cleaning device further includes a power battery configured to supply power to the handheld cleaning device. The surface-moving portion further includes at least two non-coaxial brushrolls configured to clean stains on the surface to be cleaned. The rotation speed of each brushroll is less than 3000 r/min.

A cleaning device and methods for cleaning are provided. In one embodiment, the cleaning device includes a head assembly, a body assembly, and a handle assembly. The cleaning device also includes components that enable the cleaning device to operate in dry cleaning modes and wet cleaning modes. Dry cleaning modes can employ a vacuum assembly, including a motor, tubing, and a fluid recovery tank in order to draw in debris and waste into a fluid recovery tank. Wet cleaning modes can further employ a fluid supply tank, a pump, and tubing in order to supply fluid to a brushroll to aid in a cleaning process.

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 surface cleaning apparatus such as an extractor has a fluid flow path extending from a dirty fluid inlet head to a clean air outlet. The fluid flow path upstream of the separation stage comprises a removable portion.

A floor cleaning machine is provided, in particular a hand-guided and/or hand-held floor cleaning machine, including a support device, at least one cleaning roller arranged on the support device, capable of being driven in rotation and provided with a cleaning substrate, said cleaning substrate being made of a textile material; and at least one mouth towards the at least one cleaning roller that includes a first and a spaced second mouth wall having a mouth opening therebetween, wherein the first mouth wall is positioned above the second mouth wall relative to the direction of gravity, wherein the first and/or second mouth wall protrude(s) into the cleaning substrate of the at least one cleaning roller.

A cleaning base station for a cleaning robot includes a base. The base defines a maintenance space. The cleaning base station further includes at least two of a debris suction device, a sewage pumping device, a cleaning liquid pumping device, a filtering device and a sterilization device. The at least two of the debris suction device, the sewage pumping device, the cleaning liquid pumping device, the filtering device and the sterilization device are installed in the maintenance space.

A floor cleaner including a base movable over a surface to be cleaned, a suction nozzle provided on the base having a suction inlet, a body portion having a fluid dispensing member selectively removable from the body portion, the body portion being pivotally mounted to the base movable between an upright storage position and an inclined floor cleaning position, a suction source in fluid communication with the suction nozzle, and a reservoir configured to provide solution. The fluid dispensing member includes a grip, a dispensing nozzle in fluid communication with the reservoir, and an actuator. The fluid dispensing member is configured to deliver solution from the reservoir through the dispensing nozzle upon user actuation of the actuator, independent of function of the base and body of the floor cleaner.

Self-cleaning features for extraction cleaners and attachments for extraction cleaners, such as accessory tools, wands, and/or hoses, are provided. The self-cleaning features are configured redirect cleaning fluid from a fluid supply system of the extraction cleaner into a working air or fluid recovery path of the extraction cleaner, including, but not limited to into the working air or fluid recovery path of a tool, wand, and/or hose of the extraction cleaner.
