Date Feb. 26, 1998An apparatus for cleaning tubs filled with a liquid, wherein a suction device which can be moved by a drive communicating with a delivery pipe is arranged on a base of the tub. The drive is operated by a pressurized fluid and drives a water wheel which is non-positively coupled to a displacement device contacting the base of the tub. A filter unit is connected to a suction pipe of the suction device. The suction device has a guide system for to and from movements and a two-way valve is actuated by limit switches for alternative opening of a passage for reversing movement of the water wheel. The apparatus can be used in a washer chamber of an aeration plant.
