ABSTRACT A chassis frame is supported on a front steering axle and a rear steering axle. Between the two axles and beneath the chassis frame, a hollow support serving as a main blow duct is pivotingly disposed. Rais- ably and lowerably connected to the support via levers is a sweeping- brush roller. Connected to the support are blowing nozzles which lead air supplied by a fan mounted on the chassis frame into a blow duct formed by a cover plate disposed in front of the sweeping-brush roller. Disposed within the blow duct are two suction ports which are connected via dirt-suction pipes to a vacuum-sweepings container disposed on the chassis frame. The outlet of the vacuum-sweepings container is connected at a dismantling point to an air-suction duct which is in turn connected to the intake of the fan. This cleaning vehicle can be used for snow clearance by opening a flap and closing another flap in an air-outlet pipe piece and by moving an operating lever from a middle position into either of two end positions.
