Disclosed is a drainage system for an automatic cleaning storage base of an electric mop. The automatic cleaning storage base of the electric mop comprises a casing member having a cleaning tank. The drainage system comprises a drain valve; an outlet end of the drain valve is connected to the outside of the casing member, and an inlet end of the drain valve is connected to the cleaning tank; the drain valve has a switch, and the switch is provided with a first rack; the drain valve is further provided with a duplex gear and a second rack; the duplex gear has a gear portion with a larger outer diameter to mesh with the first rack, and the duplex gear has a gear portion with a smaller outer diameter to mesh with the second rack.

A self-cleaning automatically-stored electrical mop includes a mop rod assembly, a mop head assembly, and a cleaning base assembly used for storing and cleaning the mop head assembly. The mop head assembly is arranged at the lower end of the mop rod assembly and includes a mop head shell which is provided with a rotatable cleaning roller and a motor used for driving the cleaning roller. The cleaning base assembly includes a shell part. A cleaning groove used for cleaning the cleaning roller is formed in the shell part, and a cleaning assembly used for scrubbing the cleaning roller is arranged in the cleaning groove. The shell part is provided with a sewage discharge system used for discharging sewage.

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 wet cleaning device, in particular a wet mop, has a cleaning roller mounted rotatably about a roller axis and a roller cover surrounding, at least in part, the cleaning roller in the circumferential direction, which roller cover has at least one movable cover element for elective sealing and/or exposing of an opening region of the roller cover. In order to enable a changeover of the wet cleaning device from a wiping operation to a regeneration operation in a particularly convenient and time-saving manner, according to the invention, the wet cleaning device has a first cover element and a second cover element which, based on a circumferential direction of the cleaning roller, can be moved in opposition to each other in order to seal and/or to expose the opening region from opposite circumferential directions.

The disclosure provides a water channel assembly including a channel shell and a filtering piece. The water channel is disposed on the surface of a cleaning roller in a seal and overturn mode so that the cleaning roller is washed by water flowing in the water channel. The filtering piece is laid in the water channel and faces the surface of the cleaning roller. As a result, the solid trash on the cleaning roller is filtered by the filter element and cannot enter the water channel, thus preventing the blockage of the waterway of the water supply system.

A robot cleaner includes a cleaning module having a left spin-mop and a right spin-mop configured to contact a floor while rotating in a clockwise direction or in a counterclockwise direction when viewed from above. The robot cleaner also includes a controller that manages the cleaning module such that, when the robot cleaner travels in a zigzag pattern including a first travel, during which the robot cleaner travels straight in a first direction, and a second travel, during which the robot cleaner travels straight in a second direction, which is opposite the first direction, a movement trajectory of the left spin-mop or the right spin-mop during the second travel overlaps a movement trajectory of the left spin-mop and a movement trajectory of the right spin-mop during the first travel.

A surface cleaning apparatus is provided with a primary fluid distributor and an auxiliary fluid distributor. Each distributor can have a separate and independent flow control actuator. The flow control actuator for the auxiliary fluid distributor is operably coupled with a push-push flow control mechanism, where push-push flow control mechanism has a push on/push off configuration such that pushing the auxiliary flow control actuator once starts fluid flow from the auxiliary fluid distributor and subsequently pushing the auxiliary flow control actuator again stops fluid flow from the auxiliary fluid distributor.

The embodiments of the present application provide a cleaning device and a roller brush component. The roller brush component includes a mounting base, a roller brush frame, an adjusting mechanism, a first roller brush and a second roller brush. A notch is formed on one side of the mounting base. The roller brush frame is rotatablely connected with the mounting base. The adjusting mechanism is in driving connection with the roller brush frame to drive the roller brush frame to rotate. The first roller brush and the second roller brush are connected with the roller brush frame, and the roller brushes are positioned in the notch. The roller brush frame, the first roller brush and the second roller brush are configured such that the first roller brush and the second roller brush may have different ground clearances during rotation of the roller brush frame.

A surface cleaning apparatus includes an upright body and 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 surface cleaning apparatus includes a fluid delivery system and a fluid recovery system, as well as a hybrid brushroll including a dowel, a plurality of bristle extending from the dowel, and microfiber material provided on the dowel between the bristles. The hybrid brushroll is suitable for use on both hard and soft surfaces, and for wet or dry vacuum cleaning.
