ABSTRACT:
A sweeper-scrubber is provided which has a towable scrubbing unit. The scrubbing unit is substantially self-contained, including scrubbing brushes, a pick-up squeegee, a liquid supply tank, and a recovery tank. The sweeper has an arcuate tow bar with a steerable rear wheel located behind the center of curvature of the tow bar. The scrubbing unit has a hitch which engages the arcuate tow bar and can move longitudinally therealong to achieve a high degree of maneuverability. The scrubbing unit also has a multiple reel assembly for flexible lines which supply hydraulic fluid and electrical power from the sweeper. This assembly takes up slack in the flexible lines.
