A SWIMMING POOL CLEANING APPARATUS AND A METHOD FOR SELECTIVELY RAISING OR SINKING A HOSE OF THE APPARATUS IN A SWIMMING POOL

摘要

There is provided a cleaning apparatus (10) for cleaning a swimming pool (12). The apparatus includes a hose (18) for the passage of water (24) from the pool and deformable means (28, 38) able to be deformed from a resting state to a working state by a pressure differential produced when water is drawn through the hose from the pool, such that the buoyancy of the hose is altered to enable the hose to float. The deformable means is adapted to be able to automatically return to the resting state from the working state to thereby cause the hose to sink when the pressure differential has been removed. There is also provided a method for selectively causing the hose of the cleaning apparatus to rise or sink in the pool.
