Abstract (en)

A pool cleaner comprises an electrically driven endless track vehicle drawing water through a filter compartment and expelling the water normal to the surface on which the vehicle runs. The endless tracks (22) and a pump impeller (33) are driven by a single motor (30). The impeller (33) is mounted on a shaft (34) co-axial with the motor (30). The endless tracks (22) are driven through a reduction gearing system. The eye of the impeller is open to a space containing a filter (15, 16) and the impeller (33) expels water radially into a volute manifold (14) in a direction normal to the surface on which the vehicle runs.
