ABSTRACT:
A multi-purpose floor cleaning tool for use in picking up or collecting wet or dry media is disclosed, and includes a first passageway connecting a first side of the tool to a vacuum line, a second passageway connecting a second side of the tool to the vacuum line, and an adapter for optionally closing off the second passageway during use of the first passageway or for closing off the first passageway during use of the second passageway. One of the passageways is used exclusively for dry media whereas the other passageway is used exclusively for wet media. This requires re-positioning of the tool for the proper orientation of the dry or wet media passageway, as desired.
