<p>A suction pad 10 for an automatic pool cleaner has a general periphery, for example round. In a peripheral region 28 only, the pad 10 includes, intermittently in circumferential spacing, a plurality of raised formations 24 which, preferably, project radially outwardly beyond the general periphery. Edges of the formations may advantageously be undulating or scalloped to render the periphery wavy - both when seen in plan view and in side view. In use, the raised, projecting formations 24 can pass over and flexibly envelope obstacles such as debris, and irregularities of a submerged surface such as proud standing formations.</p> |
