Patent ID: 7578010

Claim:
A method of cleaning a swimming pool, the method comprising: providing a cam operated swimming pool cleaning head and nozzle assembly comprising at least a first and a second saw tooth member within the assembly, each saw tooth member comprising a first side and an opposite side; vertically translating the nozzle upward and simultaneously incrementally rotating the nozzle clockwise to an extended position in response to application of water pressure within the nozzle, the nozzle being guided in its incremental rotation by the first side of the first saw tooth member; ejecting a stream of water through an outlet of the nozzle and directing the stream to a surface of the swimming pool when the nozzle is in the extended position; vertically translating the nozzle downward and simultaneously incrementally rotating the nozzle clockwise from the extended position to a retracted position in response to cessation of the water pressure within the nozzle, the nozzle being guided in its incremental rotation by the first side of the second saw tooth member; incrementally rotating the nozzle in steps through a predetermined number of degrees each time the nozzle is vertically translated until a predetermined degree of angular rotation is reached; repositioning a cam reverser operatively associated with the nozzle when the nozzle is vertically translating; vertically translating the nozzle downward from the extended position to the retracted position and simultaneously incrementally rotating the nozzle counter-clockwise after the cam reverser is repositioned and in response to cessation of the water pressure within the nozzle, the nozzle being guided in its incremental rotation by the opposite side of the second saw tooth member; and vertically translating the nozzle upward to the extended position and simultaneously incrementally rotating the nozzle counter-clockwise in response to application of water pressure within the nozzle, the nozzle being guided in its incremental rotation by the opposite side of the first saw tooth member.
