Abstract: 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. Retractable elements carried proximate the inlet form a plenum for water to enhance adherence of the pool cleaner to the submerged pool surface being cleaner. A drive train independently drives each of two wheels for maneuvering the pool cleaner in forward and reverse directions along the submerged surface. 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.
