A baseplate for a robotic self-propelled pool cleaner having one or more inlet openings through which water-borne debris passes prior to filtration is provided with downwardly depending inlet extension members having walls that define an opening corresponding in shape to the baseplate inlet opening and that are mounted in close-fitting relation to extend the water intake opening towards, but without touching, the pool surface to increase the suction force at the surface. The baseplate optionally includes a rotatable wheel mounted in an inboard recess in the baseplate on, or adjacent to the longitudinal centerline of the cleaner to facilitate passage over obstacles that would immobilize the pool cleaner by contact with an inlet extension member.
