ABSTRACT:
A turbine driven underwater pool cleaner is disclosed having a housing to which is attached a hose providing a source of suction. The suction functions to draw debris into and through the housing via an opening at the bottom surface of the housing. A rotatable turbine is provided in the flow path of the fluid being drawn through the housing. A pair of wheels are provided which are mounted both for rotation and translation with respect to the housing. A pair of shafts extend from and are driven by the turbine. A radial projection is provided at the end of each shaft. During each revolution of the shaft, the radial projection provides both a rotational and a translation force on the wheel for driving the cleaner in a sure manner about the pool surface. Two alternate approaches are disclosed for steering the cleaner. In one approach, the drive to one of the wheels is selectively disengaged. In another embodiment, the device is steered by placing a torque on the suction hose.
