Abstract: A swimming pool cleaning device for automatically cleaning a submerged surface includes a forwardly inclined housing forming a flow passage including a flow control valve. A flexible planar disc extends around an inlet to the flow passage for engaging the surface to be cleaned. The flexible planar member includes slits extending from the peripheral edge inward toward the central opening to form a pedal-like segmented flange for splaying of each segment in response to travel of the cleaner over an irregularly contoured surface and facilitate an effective frictional contact with the surface. A steering mechanism driven by fluid flow through the housing causes the housing to rotate about the planar disc.

Abstract: A swimming pool cleaning device for automatically cleaning a submerged surface includes a forwardly inclined housing forming a flow passage between a surface to be cleaned and a suction hose. A flow control valve is operable within the flow passage and includes a flap pivotable from a seated position against the front wall of the housing for blocking flow through the passage to an unseated position in a spaced relation to the forward wall, permitting. A shoe is carried at an inlet to the flow passage and a flexible planar disc extends around the shoe for engaging the surface to be cleaned. A groove within the shoe bottom surface forms a channel with the surface for passage of debris and fluid flow through the channel.
