Abstract
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.
