A robot cleaning system, including: a cleaning robot connectable to a mopping module of the cleaning robot, and a base station provided for the cleaning robot to dock, the cleaning robot includes: a main body; a mobile module; and a connection assembly, configured to detachably dispose the mopping module on the body of the robot; the base station includes: a storage module, configured to store at least one mopping module; an operating position, for the cleaning robot to dock to replace the mopping module; and a transfer module, configured to transfer the mopping module between the storage module and the operating position; and the robot cleaning system further includes a control unit. Beneficial effects of the present disclosure are: the cleaning robot is more intelligent, and the corresponding base station is compact in structure and small in occupied area.

An autonomous floor cleaner can include a brush chamber, a brushroll rotatably mounted in the brush chamber, a controller for controlling the operation of the autonomous floor cleaner; and a fluid delivery system with a supply tank and at least one fluid distributor configured to deposit cleaning fluid onto a surface to be cleaned.

A surface cleaning apparatus is provided with a housing including an upright assembly and a base assembly moveably mounted to the upright assembly, the upright assembly forming a stalk, a fluid container provided on the housing, a fluid distributor provided in the base assembly in fluid communication with the fluid container, a working air path through the housing, a recovery container provided on the housing and defining a portion of the working air path, a suction source provided on the housing and defining a portion of the working air path, a suction nozzle provided on the base assembly.

A surface cleaning apparatus includes a recovery tank, a suction nozzle in fluid communication with the recovery tank, and a suction source in fluid communication with the suction nozzle and the recovery tank to generate a working air path to transport debris-containing fluid including air and liquid from the suction nozzle into the recovery tank. An air/liquid separator can be provided within the recovery tank for separating liquid from air in the debris-containing fluid.

A cleaning robot and an automatic cleaning method thereof, to implement automatic cleaning. The cleaning robot includes a lifting mechanism and a cleaning base, where the cleaning base includes a base body, a scraping mechanism disposed on the base body, and a spraying assembly provided with nozzles. The nozzles are arranged along a mopping component of the cleaning robot and formed into a structure for spraying water or mist to the mopping component. The scraping mechanism includes a scraper, and the scraper comes into contact with and moves relative to the mopping component, to scrape off the attachment on the mopping component while squeezing out the water. The lifting mechanism causes the mopping component to lift or move down by causing the mopping component to come into contact with or separate from the scraper.

An upright walk-behind microscrubber apparatus including a handle assembly connected to a base assembly, and featuring an improved handle function. The handle assembly is manipulated by the user to operate the apparatus. The apparatus provides a releasable, lockable, joint assembly that connects the handle assembly to the base assembly, whereby the handle assembly is pivotally connected to the base assembly. The joint assembly permits the handle assembly to be disposed in a fully released configuration in which the handle assembly is freely pivotal relative to the base assembly, or in a fully locked position in which the handle assembly is temporarily locked in an upright orientation. The joint assembly permits the base assembly to be released to a use position generally parallel to the floor, or releasably locked in a storage position generally parallel to the handle assembly but with the base assembly's scrubbing brushes removed from the floor.

A mop unit lifting device and a cleaning machine are provided. The mop unit lifting device includes a mop unit, a lifting mechanism for lifting the mop unit; and a driving mechanism for driving the mop unit to rotate. The driving mechanism is a first driving mechanism that is configured not to be lifted together with the mop unit, and the lifting mechanism and the mop unit are formed in one piece or separate pieces; or the driving mechanism is a second driving mechanism that is configured to be lifted together with the mop unit, and the lifting mechanism and the mop unit are formed in separate pieces.

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 mobile cleaning robot can include a body, a drive wheel, and a wheel stop. The drive wheel can be connected to the body and can be operable to move the mobile cleaning robot about an environment. The wheel stop can be movable with respect to the body and the drive wheel between a stop position and a release position. The wheel stop can be engageable with the drive wheel in the stop position to limit vertical travel of the drive wheel with respect to the body.

A surface cleaner may have various features including an engagement mechanism secured to an agitator support frame and positioned to be pivoted by an agitator lift lever as the agitator lift lever translates, the pivoting engagement mechanism lifting the agitator support frame and the agitator secured thereto from a lowered position to a raised position. Other features may include a projection to limit belt slack when the agitator assembly is raised, a compact detent mechanism for releasing a spine assembly in an upright surface cleaner, a compact motor drive assembly, a self-priming centrifugal pump, a fluid-dispensing system having a high flow operating state and a low flow operating state, and a clean-out tray in which a base of the surface cleaner may be docked.
