Abstract
In order to keep the dimensions of the drive motor as small as possible in a combined high pressure cleaning and suction appliance incorporating a drive motor whose drive shaft drives both a high pressure pump and a suction fan, it is proposed that the drive shaft of the drive motor be connected to the high pressure pump and to the suction fan via a respective coupling, and that there be provided switching means which, on each occasion, selectively close one of the two couplings and open the other one.
