Abstract
This invention is concerned with flexible plastics material discs which are shaped to engage around the inlets to automatically operating swimming pool cleaners which are caused to move by an interruption of the flow induced through the cleaner by the pump of the pool filtration plant. The discs act to hold the cleaner against the surface to be cleaned and the invention provides guides on the upper surface of the disc preferably in the form of radially extending ribs decreasing in height towards the periphery of the disc. The guides direct dirt over the disc into the inlet of the pool cleaner.
