<p>Apparatus for use with automatic pool cleaners includes a tube which defines a flow channel for water drawn pump from the pool through a house by a remote pump. The tube includes tubular sections (10A, 10B) joined by a joint (11) which operates to move one tube section between first and second angularly displaced positions. Means are provided for periodically causing the movable tube section to move about the joint with sufficient force to impart movement to the hose to cause a change in direction of the cleaner.</p> |
