How does the Sweeper work? 

The Schwarze sweeping action is caused by a knife edge jet of air hitting the pavement surface. This high pressure, full width jet dislodges dust. dirt, screenings, leaves and litter, even out of cracks and gaps in the road surface such as joints, holes and cobblestones.

Once adhesion is broken, the debris is blasted forward into the path of air moving at high speed across the front chamber of the sweeping head and up the left hand side into the hopper.

The debris laden air enters the hopper at an angle and is directed towards the right rear of the hopper. As the litter is deposited, the air continues in a circular motion and after passing through a filter is drawn back into the blower unit to begin its action again.

As the debris is packed into the hopper under pressure, rather than just dropped in, the hopper's space is more efficiently and densely loaded, thereby increasing payload capacity.
