Abstract
A high pressure cleaning means is described with a preferably portable housing having a high pressure pump (6) and an electric motor drive (7) for the high pressure pump (6), the motor drive having an electric drive motor (8) with a drive shaft (9) connected to the high pressure pump (6). The motor drive (7) has at least a second electric drive motor (11) and the electric motors (8, 11, 12) of motor drive (7) are coupled to one another so as to drive the high pressure pump (6) jointly. The use of universal motors as the electric drive motors (8, 11, 12) is especially advantageous. The motor arrangement is also applicable to hand saws, water pumps, shredders, vacuums (wet/dry vacuums, leaf vacuums) and various other assemblies.
