摘要： 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.

摘要： A cleaning device includes an air flow generator for generating an air flow, which encompasses a first suction flow through a first suction line, which is arranged in flow direction of the air flow upstream of the air flow generator and which leads into a first collecting container, and a pressure flow in a pressure line, which is arranged in flow direction of the air flow downstream from the air flow generator. Using a Venturi nozzle, the air flow generates a second suction flow, which is separated from the first suction flow, through a second suction line, which leads into a second collecting container.
