Abstract (en)

A swimming pool cleaning device (10) for automatically cleaning a submerged surface (12) includes a forwardly inclined housing (100) forming a flow passage (110) between the surface (12) to be cleaned and a suction hose (16). A flow control valve (200) is operable within the flow passage (110) and includes a flap (202) pivotable from a seated position against the forward wall (102) of the housing (100) for blocking flow through the passage (110) to an unseated position in a spaced relation to the forward wall (102), permitting. A shoe (302) is carried at an inlet (112) to the flow passage (110) and a flexible planar flange (304) extends around the shoe (302) for engaging the surface (12) to be cleaned. A groove (310) within the shoe bottom surface forms a channel with the surface (12) to be cleaned for passage of debris and fluid flow through the channel. The flexible planar flange (304) 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 (400) is operable between the housing (100) and shoe (302) for rotating the housing (100) about the shoe (302) and flange (304), and includes a ratchet and pawl (402) 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 (110), while biasing against rotation in an opposing direction. <IMAGE>
