A cleaning apparatus may include a cleaning unit that is kept from moving downwardly from a predetermined limit position. The apparatus body includes a positioning member that positions the cleaning unit at the limit position. The cleaning unit includes an intake nozzle that is arranged at a position separated from the surface to be cleaned by a predetermined gap, a cam member that holds the cleaning unit at the limit position, and an operation input unit that changes the limit position to a higher position by moving the cleaning unit upward by operating the cam member.

The present disclosure discloses a floor cleaning apparatus, comprises a cleaning robot and a washing base, and the cleaning robot comprises a robot main body and a mop assembly; the mop assembly is provided with a turntable-type mop mechanism able to stretch out downwards; the washing base comprises an outer container, a rinse tank and a solution-feeding mechanism. In the technical scheme disclosed, the automatic floor cleaning and finishing cloth washing are achieved so as to realize intelligent automatic cleaning, effectively removing dirt attached to the finishing cloth automatically, and freeing from artificially detaching and then washing the finishing cloth stained with dirt, automatically performing washing operation, and greatly alleviating operation burden of a user. Meanwhile, with the structure of the finishing cloth with a lifting structure, secondary pollution caused by the finishing cloth is avoided.

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 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 cleaning assembly for a cleaning robot is provided. The cleaning assembly includes a motor, a transmission mechanism coupled with the motor, and a cleaning device comprising a shaft having a first gear coupled with the transmission mechanism and a cleaning module mounted to an end of the shaft. The transmission mechanism is configured to drive the shaft to rotate through the first gear. The shaft is configured to move axially. The cleaning module is configured to clean a surface area.

An automatic cleaning device includes a mobile platform, a lifting station, a cleaning module, a liquid supplying module, and a collecting module. The mobile platform is configured to automatically move in a target direction on a surface to be cleaned. The lifting station is connected to the mobile platform and configured to move upwards or downwards with respect to the mobile platform. The cleaning module is connected to the lifting station and configured to clean the surface to be cleaned; the liquid supplying module is configured to provide cleaning liquid to the surface to be cleaned; and the collecting module is configured to collect the cleaning liquid. A height of the cleaning module of the automatic cleaning device is adjustable, and the automatic cleaning device has a great cleaning strength and is capable of collecting dirty cleaning liquid, thus, the automatic cleaning device can be applied broadly.

A cleaning assembly includes a cleaning device, a mounting base, and a swing arm. The cleaning device is movable in a vertical direction, and a positioning part is provided on the cleaning device. The mounting base is located at one side of the cleaning device. The swing arm has one end pivotally connected to the mounting base and another end connected to the positioning part. The swing arm is configured to swing with a vertical movement of the positioning part.

An autonomous traveling floor cleaner is disclosed that improves cleaning efficiency. A floor cleaner may include a suction nozzle that suctions suction matter collected by a rotary brush, an extension nozzle that suctions suction matter collected by an extension brush, and a collection box for collecting, through an inlet, the suction matter suctioned by the nozzles. The floor cleaner may have an elongated profile. The extension nozzle may be switchable between a retracted posture and a lateral cleaning posture. The extension nozzle in the lateral cleaning posture may be pivotable rearward. The extension nozzle in the lateral cleaning posture may have a protruding end in the width direction to be aligned with an end of a turning range of the floor cleaner in the width direction.
