Abstract:
A wet/dry cannister-type vacuum cleaner is provided with a plastic grid unit that includes a spherical cup-like main section, an upper annular mounting lip, a short tubular support disposed within the main section with the lower end of the support surrounding a central inlet opening in the latter, and a grid extending across the support at the top thereof and disposed below the mounting lip. The lower end of the support constitutes a seat for a floating ball valve element. An axially extending slot in the support provides a drain for liquid that may be accumulated by the main section at the interior thereof.
