Abstract: The present invention relates to a pressure pad unit for use in a swimming pool cleaner of the vacuum suction type having a body and a suction inlet. The pressure pad unit allows the cleaner to traverse relatively small radius transitions between horizontal and vertical surfaces without significant loss of vacuum. The pressure pad unit is comprised of a circular disc of flexible plastics material, a central opening defined in the disc for engaging around the suction inlet of the cleaner body, and a plurality of equally circumferentially spaced radial slots. The slots have parallel sides and extend from the outer peripheral edge of the disc across a major portion of the radius thereof toward the central opening. The slots divide the disc into an equal plurality of independently flexible segments which are capable of following pool wall transitions and curvatures.
