Abstract
A push side pool cleaner (1) has a spheroidal overall shape, within this shape two outer segments (9, 10) serve as wheels and a central zone (8) carries a suction passage (33) and a debris collector (32) also located entirely within the overall shape. The wheels are driven directly by water jets (44, 45) without any gears or other transmission. A flow splitter is provided in the cleaner (1) to divide push side water flow between the jets (44, 45) which drive the wheels and jets (43) which provide impulsion to the suction passage (33).
