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 supply unit for a cleaning machine which can be connected via at least one flexible hose, has a heating device for heating water, a water pump for conveying water into or out of the heating device, a hot water and/or steam connector which is connected to the outlet of the heating device, a dirty water tank, a suction device, which preferably includes a suction turbine, for sucking dirty water from a dirty water connector into the dirty water tank. In a preferred embodiment the unit has at least one, preferably precisely one central, drive unit for driving at least one, preferably a plurality of or all components to be driven of the supply unit and/or of a cleaning machine to be connected to it.

A surface cleaning device comprises a cleaning head having a housing, a fluid tank configured to store fluid and be in fluid communication with the cleaning head, a cleaning pad coupled to the cleaning head and configured to remove debris from a surface, and a plurality of nozzles distributed along the cleaning pad, wherein the fluid tank is configured to release at least some of the fluid such that the released fluid flows through the plurality of nozzles onto the cleaning pad.

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.

A cleaning roller for a cleaning appliance, in particular a wiping roller for a wet cleaning appliance, or a cleaning appliance having such a cleaning roller processes an area to be cleaned. The cleaning roller has a roller core that can rotate about a longitudinal axis and has a bearing for a drive shaft and a roller cover surrounding the roller core in the circumferential direction. The roller core, based on a cross section perpendicular to the longitudinal axis, has several spring elements formed beside one another in the circumferential direction of the cleaning roller, each of which extends from the bearing to the roller cover.
