ABSTRACT:
An improved disposable filter bag for use with a pool cleaner of the type disclosed, for example, in U.S. Pat. Nos. 5,863,425; 4,558,479; and 3,822,754. The filter bag is formed from a porous filter material such as a non-woven spunbond polymer having marginal seams formed by direct welding, in the absence of additional adhesive material, to form a reinforced cuff defining an open bag mouth leading to a hollow bag interior. The cuff is configured for removable attachment to a downstream end of a pool cleaner suction mast, as by removable connection to a mounting collar as disclosed in U.S. Pat. Nos. 5,863,425; D409,341; D468,067; and 6,740,233. The filter bag incorporates a ported tab formed generally at an upper end thereof for facilitated removable coupling to a pool cleaner supply hose or the like which supports the filter bag in a generally upright orientation.
