1. A pool cleaner comprising:

  • a housing having an inlet;

    two wheels operable for driving the housing along a submerged surface, wherein an outer diameter of at least one of the wheels defines a perimeter thereof;

    a roller operably carried by the housing forward the inlet, the roller having a tubular shape defined by an outer surface and an inner surface;

    an axle carried by the housing, wherein the inner surface of the roller is slidably rotatable about the axle, and wherein the axle is dimensioned for permitting the roller to extend beyond the perimeter and operable for retracting the roller within the perimeter responsive to movement along the submerged surface; and

    a retractable element operably carried by the housing aft the inlet, the retractable element moveable from outside the perimeter to inside the perimeter responsive to movement along the submerged surface, wherein the retractable element and the roller in combination partially form a plenum for enhancing adherence of the pool cleaner to the surface during a flow of liquid through the inlet.
