Discs and a footpad for devices such as automatic swimming pool cleaners are disclosed. The discs incorporate upwardly-extending, non-truncated fins protruding radially from their peripheries. The peripheries themselves, moreover, define a plurality of tongues for increased flexibility, and both the discs and footpad may include ramped segments facilitating movement over obstacles extending from swimming pool surfaces. Also disclosed are discs having series of slits spaced along portions of their peripheries. Each such disc may be part of an assembly including a 'bib,' or cap, that too may be slitted if desired. The slits of each component, when present, permit its effective surface area to increase as the associated cleaner climbs the side of a swimming pool, enhancing the maneuverability of the cleaner. By contrast, unslitted portions of the cap seal, or cover, the slits present in the disc to provide adequate suction for the disc against the pool surface.
