Abstract
A domestic automatic swimming pool cleaner which randomly travels about and cleans the walls and bottom surfaces of a swimming pool includes two parallel or non-parallel impact tubes, the top ends of which are connected to a flexible suction hose which in turn is connected to the suction side of the pool's filter pump. The bottom ends of the tubes are served intermittent shots of water by a hinged self-starting flapper valve with an unrestricted upstream opening in the cleaner's pool surface contacting head. By the action of the valve alternately delivering pool water to the two tubes, kinetic forces are generated which move the automatic pool cleaner about the pool.
