ABSTRACT:
A pool cleaning method and apparatus in which a vortex is generated to concentrate foreign material at the center of the pool. The vortex can be generated by a pool scrubbing procedure carried out in a systematic manner. The scrubbing and vortex inducing procedure can be carried out by manual means. Large particulate matter is thus suspended in the vortex center and can be removed from the pool with a commercially avaiable strainer. Fine particulate sediment is then removed from the pool center by a manually reciprocated suction device which draws debris laden water from the floor of the pool through a disc shaped filter which retains microscopic particulates. Filtered water is then ejected through the top of the device's barrel assembly.
