Filter bag for pool cleaners

Abstract

An improved filter bag is provided for swimming pool cleaners and the like particularly of the type designed for travel along submerged pool surfaces to dislodge and collect debris. The filter bag is formed from an elongated stretch of porous fabric, such as nylon mesh, folded upon itself to define conforming left and right sidewalls joined by front and rear seams and a seamless upper end. The lower ends of the sidewalls are secured to a mounting collar which cooperates therewith to define an open mouth for entry of debris into the bag and means for attachment about the discharge end of a pool cleaner suction mast. Water and debris are drawn by the cleaner through the mounting collar into a primary flow chamber within a forward region of the filter bag and separated from a rear collection chamber by an upstanding divider seam which terminates below the seamless upper end of the bag. In use, upon forward travel of the pool cleaner within a swimming pool, water flows relatively efficiently through the primary flow chamber and exits the bag through the seamless upper end, while debris drawn upwardly within the primary flow chamber is guided rearwardly over the divider seam and settles within the rear collection chamber. A portion of the rear seam is defined by separable Velcro-type fastener strips to permit removal of debris from the collection chamber without requiring removal of the filter bag from the pool cleaner.
