Abstract
A lower section has an open bottom, a closed top, and intermediate front and side panels defining a vacuum chamber there within. Each panel has a lower generally vertical leg with a horizontally disposed pivot pin couples each panel to the top. A bumper extending outwardly from each vertical leg moves into operative proximity with an edge of a floor and pivots a panel to increase the size of the vacuum chamber for overlying and vacuuming dust adjacent to the edge of the floor.
