The PowerBoss Admiral 40 Sweeper/Scrubber takes cleaning to the next level. With one pass of the machine, you perform three functions: pre-sweeping, wet scrubbing and dry vacuuming. First, the machine sweeps up any fine or coarse dirt with its powerful vacuum blower with dust filter. Then two directly driven disc brushes intensely scrub away even the most stubborn dirt. Finally, the parabolic squeegee dry vacuums, leaving the floor dry enough to walk on.
