Directional control means for robotic swimming pool cleaners
First Claim
1. Directional control means for an automatic swimming pool cleaner of the type having a housing, with front and rear ends and two sides, a pair of motor driven cylindrical brushes rotatably mounted on the front and rear ends of the housing respectively for propelling the cleaner along the bottom surface of a swimming pool, said control means comprising a projectable leg mounted on one side of the housing between the front and rear ends;
- and means to reciprocably operate the leg for projected movement into contact with the bottom surface of the swimming pool to partially lift one side of the cleaner from said surface as it is propelled therealong causing the cleaner to pivot around the projected leg to change direction.

Abstract
Directional control means are provided for robotic swimming pool or water tank cleaner of the type having an internal filter bag for removing and retaining debris from the pool, an electric pump for drawing water through the filter bag and two parallel motor driven cylindrical brushes for propelling the cleaner along and sweeping the bottom surface of the pool, said control means including one or more water activated hydraulic cylinders located on the side of the cleaner between the brushes, each containing a leg adapted to project downwardly to contact the pool bottom and partially lift one side of the cleaner. As the cleaner moves along the pool bottom it pivots around the projected leg to change direction. Manual or automatic means can be provided to activate the hydraulic legs.
