An improved disposable filter bag (10) for use with a pool cleaner (12) of the type disclosed, for example, in U.S. Patents 5,863,425; 4,558,479; and 3,822,754. The filter bag (10) is formed from a porous filter material such as a non-woven spunbond polymer having marginal seams (28,32,34,36) formed by direct welding, in the absence of additional adhesive material, to form a reinforced cuff defining an open bag (30) mouth leading to a hollow bag interior. The cuff is configured for removable attachment to a downstream end of a pool cleaner suction mast (24), as by removable connection to a mounting collar (38) as disclosed in U.S. Patents 5,863,425; D409,341; D468,067; and 6,740,233. The filter bag (10) incorporates a ported tab (14) formed generally at an upper end thereof for facilitated removable coupling to a pool cleaner supply hose (16) or the like which supports the filter bag (10) in a generally upright orientation.

L'invention concerne un sac-filtre jetable amélioré, destiné à être utilisé avec un robot nettoyeur de piscine du type décrit, par exemple, dans les brevets U.S 5863425 ; 4558479 ; et 3822754. Le sac-filtre est formé à partir d'un matériau poreux tel qu'un polymère filé-lié non tissé présentant des coutures marginales formées par soudage direct, en l'absence de matériau adhésif supplémentaire, afin de former un revers renforcé définissant une bouche de sac ouverte conduisant à un intérieur de sac creux. Le revers est conçu pour la fixation amovible à une extrémité aval d'un mât d'aspiration d'un robot nettoyeur de piscine, tel que par raccordement amovible à un collier de montage tel que décrit dans les brevets U.S. 5863425 ; D409341 ; D468067 ; et 6740233. Le sac-filtre comprend une languette portée formée généralement au niveau d'une extrémité supérieure de ce dernier afin de faciliter l'accouplement amovible à un tuyau d'alimentation de robot nettoyeur de piscine ou analogue qui supporte le sac-filtre de manière généralement verticale.
