In a combination sweeping, polishing and scrubbing floor maintenance machine, the present invention includes a debris hopper removably positioned in a frame secured to a portion of the machine. The debris hopper has a rearward opening facing a pair of substantially side-by-side disc tools, e.g. brushes. The brushes preferably rotate in the same rotational direction with one brush positioned slightly ahead of the other brush. Immediately in front of the forward edge of the leading brush is a conduit means secured to the hopper. Adjacent the conduit means and extending along the hopper opening is a flexible member. Both the flexible member and the conduit means serve as debris receiving means for directing swept debris upwardly into the debris hopper. Blade members may be provided forward of the debris receiving means and beneath the hopper to guide debris into a central area of the machine\s path of travel.
