The BSW 28 sweeper is powered by a gel battery, has a 28 inch wide
sweeping path, self propelled traction, and features active dust
control. The active side broom on the BSW 28 sweeps even the smallest
debris and dust from the walls edge into the large main broom path for
placement into a large hopper. The large hopper is easy to remove for
emptying, and provides total access to the main broom and large dust
filter. Large traction wheels provide smooth operation. The BSW 28 is
very quiet at only 59 dBA, which allow sweeping in noise sensitive
areas.
