A buoyant, closed-wall member (12) is secured in a leakproof manner to sheet (11) to define a relatively shallow, pan-like container for floating on the surface of the water. Apparatus (10) also includes a relatively short length of tube pivotally mounted to the outer periphery of the container for holding a vacuum or suction pipe of the kind used to clean a swimming pool.
