ABSTRACT:
A pump and filtration system for a pond or pool. The filtration mechanism has a collapsible bag in which dirty water is forced through it from one direction in order to clean the water while cleaning water is forced through the bag in the opposite direction in order to clean the filter bag. The filter bag is positioned in a housing and separated from the walls of the housing by a mesh or screen-type member. A tapered nozzle (water jet member) is used to increase the flow of the water entering the flotation unit. A tubular member is lowered through the housing in order to clean contaminants from the collapsible filter bag. The dirty water is directed to a flower bed or the like.
