The Duplex 420 washes, sweeps and disinfects, and is particularly effective on uneven floors and gaps; it is extremely easy to handle and operate.

With its compact design, its brushes, tanks and centrally located motor are all laid out to make it perfectly balanced.

The Duplex 420 is the only machine which cleans right up to the wainscoting and into hard to reach corners.

Duplex has created the simplest and most versatile solution for deep cleaning and drying any floor, with total recovery of fluid and solid dirt.


  • Bi-directionality: its innovative design and manoeuvrability allow the user to reverse the Duplex 420’s direction simply by inverting its handle. This “about face” function is very quick, and makes it incredibly easy to clean from right to left/forwards and backwards and vice-versa – especially in restricted spaces.
  • Prewash function: Duplex products have the option of disabling detergent solution recovery for prewashing, a huge benefit when cleaning very dirty floors.
  • Brush pressure adjustment: the brush pressure can be adjusted for better cleaning results.
  • Total cleaning of even the most challenging areas of the floor: the Duplex 420 cleans under furniture, along the wainscoting and in hard to reach corners.
