ABSTRACT:
The present invention provides an apparatus for cleaning floors. In one embodiment, the apparatus includes four wheels, two of which are steerable wheels, and a steering mechanism that permits the two steerable wheels to turn to a degree that allows very tight turns to be made by the sweeper. In another embodiment, the apparatus is a sweeper with a cylindrical side broom. Yet a further embodiment of the sweeper includes flaps or seals that form a skirt about the broom and a mounting mechanism for slidably receiving the flap or seal. In a further embodiment, the apparatus is a sweeper that employs flaps with wear indicators that tell an operator when to adjust or replace the flap. In another embodiment, the apparatus is a sweeper that utilizes a pre-filter to remove debris that remains in the vacuum airstream after having passed through the hopper and that is of a size that can require frequent cleaning of a subsequent filtering device. In yet a further embodiment, the apparatus is a scrubber with two counter rotating disk brushes, a primary squeegee, and a second or pre-squeegee for relieving the primary squeegee from processing the heavier concentration of wastewater produced in the area between the brushes. In yet another embodiment, the apparatus is a scrubber that includes a squeegee mounting systems that is relatively easy to use and permits the squeegee rubber to extend beyond the end of the mounting structure.
