ABSTRACT:
A motor-driven propulsion device (10) can be attached separately to a surface-cleaning machine (1), which has a drive (2) for a rotor drum and is equipped with a handle supporting deck (3) for manual propulsion. For this, the device (10) is connected mechanically to the handle supporting deck (3) and secured to the axle (5) of the surface-cleaning machine (1) with a swivel hook (34) and a two-pronged fork. In this position, at least one motor-driven frictional wheel (11) presses on the running wheels (6) of the surface-cleaning machine (1). The frictional wheel (11) is driven by a separate motor in the housing (12) of the propulsion device (10), which, if necessary, uses a separate power supply or the same power supply as the drive motor of the rotor drum of the surface-cleaning machine (1).
