Abstract: An apparatus for inducing variable randomized patterns of traversing a floor of a swimming pool by a suction cleaner device; said apparatus comprising a water flow driven mechanism for axial rotation of a pool cleaner hose; said hose located between a suction pump inlet and said suction cleaner device.

Abstract: An apparatus for inducing variable randomized patterns of traversing at least a floor of a swimming pool by a suction cleaner device; said apparatus including a water flow driven mechanism interposed between a suction pump inlet in a wall of said swimming pool and said suction cleaning device; said apparatus further including a suction hose and an angled connector attached to said suction hose; said angled connector rotatably connected to a swivelling outlet port of said suction cleaning device; said apparatus inducing substantially continuous axial rotation of said suction hose and said angled connector whereby rotating the hose and angled connector alters the geometry of the propulsion force of the pool cleaner thus steering the pool cleaner all over the pool.

Abstract: A hat having a brim configured to extend substantially around the head of a wearer, wherein a weight increasing means is provided on the brim to increase a radius of gyration of the hat. Typically, the weight increasing means is provided at, or adjacent to, a periphery of said brim.
