TURBINE-DRIVEN SWIMMING POOL CLEANING APPARATUS AND METHOD

A swimming pool cleaner is driven along a submerged surface by water and debris flowing past a turbine positioned between an inlet and outlet of the cleaner. Rollers are rotatably carried on the bottom of the cleaner and forward and aft the proximate an inlet port. The rollers in combination with lower side wall portions of the housing form a plenum for water and enhance adherence of the pool cleaner to the submerged pool surface being cleaner. A hose connector operable with an outlet port is angled toward the forward direction of movement of the pool cleaner such that a suction hose will be placed slightly ahead of the pool cleaner when climbing a side wall surface to provide a weight for keeping the cleaner below the water surface and thus prevent an undesirable sucking of air at the inlet.
