Abstract (en)
A footpad (10) for a swimming pool cleaner (12) carries a footpad (10) which itself carries a flexible vacuum seal (16) for contacting a submerged surface (18) during movement of the cleaner (12) driven by an interrupted fluid flow (20) through the cleaner (12). The footpad (10) includes a bottom contoured surface (26) and is formed from a first material making frictional contact with the submerged surface (18). The footpad (10) is characterized by a removable friction pad insert (38) locked within an aft most bottom surface portion (40) of the footpad (10). The insert (38) is formed from a second material making a greater frictional contact with the submerged surface than the first material of the footpad (10). The insert (38) further has an arcuate surface (50) generally shaped to conform to and protrude from the bottom contoured surface (26) of the footpad (10).
