Abstract:
1. A rotating cleaning assembly useful for cleaning the inside surface of a pool by agitation comprising: a. a pop up head including three aligned parts in order: an upper piston, a middle cylindrical portion, and an annular beveled flange, b. wherein said three aligned parts are each longitudinally aligned to an axis, c. wherein said upper piston and said middle cylindrical portion are closely adjacent and are connected together by friction in a manner to allow both to independently rotate about said axis, d. wherein said annular beveled flange is closely adjacent to said middle cylindrical portion, e. at least one nozzle opening on the radial surface of said upper piston, f. an impeller, impeller shaft, and mechanical gearing disposed to cause said upper piston and said middle cylindrical portion to rotate around said axis when water flows around said impeller, wherein said impeller shaft is substantially parallel to said axis, g. an insert assembly which contains said pop up head, wherein said insert assembly is placed substantially within a floor or wall of said pool, h. an intermittent water flow from a pump source to said insert assembly, i. wherein said axis is substantially perpendicular to said floor or said wall, j. wherein when said water flow is active, k. wherein when said water flow is inactive, whereby the water flow through said at least one nozzle opening provides for agitation along the inside surface of a pool.
