摘要： A pool cleaner assembly includes a pool cleaner body supported for motion over an underwater pool surface, the pool cleaner body defining a water source connection and a suction opening on a lower surface thereof through which debris is removed from the underwater pool surface. The assembly further includes a steering device having a first steering device end configured for connection to a water hose and a second steering device end connected to the water source connection of the pool cleaner body, the steering device being operable to generate relative rotational motion between the first and second steering device ends.
