How does a road sweeper work?
Typically, the brushes are capable of spinning at around 4,000 revolutions per minute (rpm). Regenerative road sweepers use a hydraulic system that forces air into a swirling effect inside a contained sweeping head. A negative pressure on the suction side is then used to suck the debris into the hopper.
What are the duties and responsibilities of a sweeper?

How does a regenerative air street sweeper work?
A regenerative air street sweeper uses forced air to create a swirling effect inside a contained sweeping head and then uses the negative pressure on the suction side to place the road debris inside a hopper. Debris is removed from the air by centrifugal separation, keeping particulate matter inside the hopper.
When was the first self propelled sweeper invented?
