The present invention is an improved method of employing a wet/dry vacuum cleaner for wet material pick-up. By employing a hydrophobic and air permeable filter material, such as an expanded polytetrafluoroethylene (PTFE), with a tight gasket around its edge in place of a conventional wet/dry vacuum filter, it has been determined that the filter can be retained in place at all times during operation, regardless of the material being collected.

La présente invention concerne un procédé amélioré permettant d'employer un aspirateur de liquides/poussières pour recueillir des déchets humides. L'utilisation d'un matériau de filtre hydrophobe et perméable à l'air, tel un polytétrafluoroéthylène expansé (TPFE), muni d'un joint étanche autour du bord de filtre, à la place d'un filtre classique à liquides/poussières, a permis d'établir que ce filtre peut être maintenu en place pendant toute la durée du fonctionnement de l'appareil, quel que soit le matériau recueilli.
