The present disclosure discloses a cleaning base station. The cleaning base station includes a base and a vibration device. The vibration device includes a driving mechanism and a cleaning element. The driving mechanism is fixed to the base. The cleaning element is connected to the driving mechanism. The cleaning element is configured to contact a part-to-be-cleaned of a cleaning robot. The driving mechanism drives the cleaning element to vibrate so as to clean the part-to-be-cleaned of the cleaning robot. The present disclosure also discloses a cleaning robot system using the cleaning base station described above. The present disclosure has the advantages of reducing a user's burden of manual cleaning and avoiding contamination of a floor surface by the part-to-be-cleaned of the cleaning robot.

A coverage robot including a chassis, multiple drive wheel assemblies disposed on the chassis, and a cleaning assembly carried by the chassis. Each drive wheel assembly including a drive wheel assembly housing, a wheel rotatably coupled to the housing, and a wheel drive motor carried by the drive wheel assembly housing and operable to drive the wheel. The cleaning assembly including a cleaning assembly housing, a cleaning head rotatably coupled to the cleaning assembly housing, and a cleaning drive motor carried by cleaning assembly housing and operable to drive the cleaning head. The wheel assemblies and the cleaning assembly are each separately and independently removable from respective receptacles of the chassis as complete units.

The present disclosure provides a surface cleaning apparatus that includes a housing including a base adapted for movement across a surface to be cleaned, a fluid delivery system, and a recovery system. The surface cleaning apparatus can be configured to clean multiple surfaces, including hard and soft surfaces, and for different cleaning modes, including wet cleaning, dry vacuum cleaning, and self-cleaning. Methods for self-cleaning a surface cleaning apparatus are also provided.

A portable surface cleaning apparatus for a floor surface includes a main housing assembly adapted to be hand carried by a user, the main housing assembly carrying a fluid delivery system adapted for storing cleaning fluid and delivering the cleaning fluid to the surface to be cleaned, and a fluid recovery system adapted for removing the cleaning fluid and debris from the surface to be cleaned and storing the cleaning fluid and debris that was recovered, the main housing assembly comprising a base housing, a supply tank received on the main housing assembly, a recovery tank received on the main housing assembly separately from the supply tank.

A surface cleaning head is provided having a casing with a rotatably mounted cleaning brush associated with a brush opening and a drying roller operable in a drying mode. In the drying mode, the drying roller removes water from the rotatably mounted cleaning brush. The surface cleaning head also has a water collection container positioned to receive water removed from the rotatably mounted cleaning brush by the drying roller.

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 surface cleaning apparatus has a fluid distribution system for storing and delivering fluid to a surface to be cleaned, and includes a steam nozzle in fluid communication with a steam generator. A pad mounting plate is adapted to mount a cleaning pad to the apparatus, and has a steam orifice in fluid communication with the steam nozzle. A flexible seal is provided between the steam nozzle and the pad mounting plate to seals a space between the steam nozzle and the steam orifice to prevent steam leaks.

Method for operating a dirt collecting device for a sweeping vehicle or for a vacuum cleaner nozzle of a floor or upright vacuum cleaner, which each comprise a suction fan with controllable speed and/or power, wherein in a first method step, the suction power of the suction fan is set at such a low level that the suction pressure in the dirt collecting device or the vacuum cleaner nozzle is merely sufficient to convey and deposit the absorbed coarse dirt into the intermediate container, and to convey the absorbed fine dirt into a downstream collection container, (normal operation); and that in a second method step, the filling level in the intermediate container is detected with respect to the coarse dirt deposited therein; and that in a third method step, if the filling level in the intermediate container is exceeded, the suction power of the suction fan is increased such that the coarse dirt, which is temporarily deposited in the intermediate container, becomes dispersible and is conveyed into the downstream collection container (emptying mode).

A cleaning device is provided. The cleaning device includes a driving roller, a driven roller, a flexible cleaning belt sleeved on the driving roller and the driven roller, a garbage collection box disposed on one side of the cleaning belt, a brush disposed over the garbage collection box, a sewage collection tank, a clean water tank and a water squeezing roller disposed on the side of the cleaning belt. The garbage collection box is provided with a guide plate near one end of the cleaning belt, and the guide plate corresponds to the outer side of the cleaning belt. The sewage collection tank and the clean water tank are located downstream of the garbage collection box along the moving direction of the cleaning belt, and the water squeezing roller corresponds to the sewage collection tank.

The present disclosure relates generally to an apparatus for cleaning or otherwise treating a floor or ground surface. Devices provided herein include various features to enhance the efficiency and efficacy of cleaning operations. Such devices includes, but are not limited to, bearing protector devices, cord and cable management devices, and ergonomic features useful with ride-on floor treating machines.
