  • One-off or cyclic road sweeping
  • 24/7 emergency response

Our regenerative road sweepers employ a closed loop, constantly re-circulating (regenerating) their air supply internally while cleaning.

The air is forced down onto the pavement on one side of the sweeping head, travels across the width of the head (collecting debris as it goes due to the air-swirling action of the head), and is then sucked up the pickup hose on the other side. Debris is removed from the air by centrifugal separation and retained in the hopper.

Gutter brooms on both sides of the machine help to brush material accumulated against the kerb into the path of the sweeper.

Compared with other sweepers, regenerative road sweepers have the following benefits:

  • They can cover a wider road area
  • Because they air blast the pavement across the entire width of the sweeping head, they are also recognised as achieving a more thorough cleaning job over the entire pavement surface covered
  • They can pick up smaller particles of debris – which are a leading cause of stormwater pollution and can also contribute to reduced air quality
  • The closed-loop prevents dust-laden air from being exhausted back into the atmosphere
  • They are less expensive to operate and maintain (with fewer moving parts) meaning savings can be passed on to customers

They can cover a wider area because they air blast the pavement across the entire width of the sweeping head.

For this reason, they are typically considered the most effective sweeper type for areas requiring high-quality cleaning, such as:

  • General urban street sweeping
  • Residential street sweeping
  • State highway and tollway sweeping
  • Motorway sweeping
