Abstract
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.
