A surface cleaning apparatus includes a housing including an upright handle assembly and a base mounted to the upright handle assembly and adapted for movement across a surface to be cleaned. The surface cleaning apparatus is further provided with a fluid delivery system comprising a fluid dispenser configured to dispense fluid to a brushroll and at least one fluid delivery channel forming a portion of a fluid delivery pathway. The fluid delivery channel can extend adjacent to a portion of the suction nozzle assembly. An interference wiper interfaces with a portion of the brushroll to remove excess liquid from the brushroll.

A base station includes a base station body, a first water tank, and a second waterway system. The base station body is provided with a cleaning system. The first water tank is removably installed in the base station body, and is configured to be manually added with clean water and/or removed with sewage. The first water tank is defined with a first cavity communicated with the cleaning system. The second waterway system includes a waterway channel arranged on the base station, and the waterway channel is configured for receiving and transporting clean water from the outside of the base station to the cleaning system and/or configured to receive sewage from the cleaning system and discharge the sewage to the outside. Both or either one of the first cavity and the second waterway system may supply clean water to the cleaning system and/or receive sewage from the cleaning system.

A surface cleaning apparatus includes a housing including an upright handle assembly, a base mounted to the upright handle assembly, a recovery system comprising a recovery pathway, a fluid delivery system, and a brushroll within the recovery pathway of the recovery system. The surface cleaning apparatus is further provided with a self-cleaning mode configured to clean the brushroll and the recovery pathway.

An autonomous floor cleaning system includes an autonomous floor cleaner with a docking station. The docking station is configured to performing maintenance for the autonomous floor cleaner, such as refilling the autonomous floor cleaner, emptying the autonomous floor cleaner, washing mopping pads, and/or recharging the autonomous floor cleaner. The docking system can supply heated cleaning fluid to the autonomous floor cleaner. Methods for servicing or performing maintenance on an autonomous floor cleaner by a docking station are disclosed.

A supply tank assembly for a cleaning apparatus includes first and second reservoirs for housing first and second liquids, respectively, and a cap assembly with a plunger. A first flow path for the first liquid is defined from the first reservoir to the dispensing outlet. A second flow path for the second liquid is defined from the second reservoir to the dispensing outlet. A switch assembly is operable between different positions to control dispensing of the second liquid. The plunger is biased toward a sealed position to seal the first and second flow paths and is configured to move to an opened position to open the first and second flow paths to concurrently dispense the first and second liquids to be mixed outside of the supply tank assembly based on a position of the switch assembly.

A method for controlling a mobile, self-propelled appliance, in particular a floor cleaning appliance such as a robot vacuum cleaner and/or a sweeper and mopping robot so as to mop up an accumulation of liquid, includes driving on a floor surface intended for cleaning in a direction of travel in a forward movement of the appliance and cleaning the floor surface by using a dry cleaning module and/or a wet cleaning module of the appliance. The accumulation of liquid is detected in the direction of travel in front of the appliance in a moist area. The forward movement in front of the moist area is terminated and the appliance is rotated about substantially 180. Driving on the moist area in a reversing movement in the direction of travel of the appliance and mopping up the accumulation of liquid using the wet cleaning module is carried out.
