Abstract
A filtration bag assembly may include an air permeable bag and a collar affixed thereto. The collar may include an opening that communicates with the interior of said bag and at least one panel that is movable to selectively obscure the opening. The collar includes a bottom surface and a pair of opposed tabs extending laterally from opposed lateral edges of the collar. A bracket is secured to the floor cleaning apparatus and includes a pair of opposed legs, that each includes a first ramp surface and a second ramp surface. During insertion of the collar into said bracket, the first ramp surface slidingly contacts the bottom surface and the second ramp surface slidingly contacts said tabs to move the collar upwardly into fluid communication with a nozzle.
