ABSTRACT:
A combination floor sweeping and scrubbing machine is as compact and maneuverable as an equivalent machine which only sweeps or scrubs, while retaining typical hopper and tank volumes. Its operator can change it from sweeping to scrubbing or vice versa at any time by moving a few controls and without adding or removing any parts. It has one debris hopper and one horizontal cylindrical rotating brush and they function in both the sweeping and scrubbing modes. A vacuum system supplies dust control during sweeping and vacuum pickup of dirty solution during scrubbing. In the scrubbing mode a single tank supplies scrubbing solution and receives dirty solution picked up from the floor.
