ABSTRACT:
A swimming pool cleaner of the pressurized water actuated, random sinuous motion, sweeping arm type is disclosed which agitates silt and other particulate debris, thereby facilitating their removal by conventional pump-driven recirculating filtering means. The random sinuous motion of the immersed sweeping arms is greatly enhanced by unique compound water discharge jets which efficiently convert water head into sweeping arm motion. The discharge jets further greatly reduce frictional wear of the sweeping arms caused by abrasion against the interior surfaces of the pool, and provide a distributed water scrubbing action of the interior pool surfaces. The compound water discharge jets are further configured to minimize the possibility of stalling of the sweeping arms due to their finding a position of static equilibrium. The apparatus and method described are equally suitable for use in industrial processes where it is desirable to provide agitation of a liquid by simple and economical means.
