ABSTRACT:
Discs for devices such as automatic swimming pool cleaners are disclosed. The discs incorporate one or more flutes, or raised areas (arched protrusions), extending generally radially from adjacent their central portions to their peripheries. The peripheries themselves, moreover, may include upturned areas (lips) between flutes, and both the discs and footpad may include ramped segments facilitating movement over obstacles extending from swimming pool surfaces.
