The Duplex Advantage

Counter-Rotating Cylindrical Brushes

The Duplex 420's revolutionary design uses two cylindrical brushes rotating in opposite directions at 650 RPM. This creates a unique cleaning action that lifts and separates carpet fibres while simultaneously agitating embedded soils.

  • Forward brush lifts fibres and loosens surface dirt
  • Rear brush deep-cleans and restores pile direction
  • 420mm coverage ensures uniform cleaning across width
