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. 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 is operable between the housing and shoe for rotating the housing about the shoe and planar member, and includes a ratchet and pawl operable between upper and lower steering members for providing free rotation in one direction in response to a pulsating fluid flow through the flow passage, while biasing against rotation in an opposing direction.
