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).
Claims12
A propulsion device (10) for a motor-driven surface-cleaning machine (1), said motor-driven surface-cleaning machine equipped for manual propulsion and having a handle-supporting deck (3) and an axle (5) extending laterally through a lower portion of said surface-cleaning machine, said axle having two running wheels (6),
- the propulsion device (10) comprising:
- a detachable coupling between the surface-cleaning machine and the propulsion device;
- a housing, said housing having at least one driven frictional wheel (11) positioned on said housing to drive at least one of the two running wheels (6) of the surface-cleaning machine when the propulsion device is coupled to the surface-cleaning machine.
