Abstract

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.
