ABSTRACT:
This invention provides an accessory for an automatic pool cleaner, to increase the randomness of movement of a suction head of the pool cleaner, and a method therefor. The method comprises looping a section of the cleaner hose and allowing the hose sections leading up to the loop to vary in length. Particularly, the hose section leading from the pump to the loop is varied. The accessory comprises two connection parts, one for connection to each respective section of hose to form the necessary hose loop. Preferably one of the parts is slidable along the hose length to enable the hose to vary its length. The sliding action of the hose occurs between two stops in the length of the hose, and a pawl mechanism is provided to enable the slide to occur in one direction towards a stop. Contact with the stop causes the pawl mechanism to switch over and slide the hose in the opposite direction.
