Floor and Carpet Cleaner

The mid range sized  Duplex 420 Floor Cleaning Machine is the most popular of the versatile Duplex range.

With it’s twin contra-rotating brushes this machine gives powerful cleaning results on all floor types including carpets, safety flooring, wood, tiles, marble, vinyl, carpet tiles, Tarkett, Altro, Marley, Flotex, Polysafe, Timbersafe, non-slip floors, resin floors, entrance matting and many more.

With a cleaning width of 420 mm (16″), the Duplex 420 Floor Cleaning Machine cleans, scrubs and picks up the dirty water. With the simple flick of a switch the brush height can be adjusted to suit all flooring types.

A pre-scrub facility is available for heavily soiled floors meaning that cleaning solution can be released onto the floor and then when the water has had a chance to do it’s job, the recovery facility can be switched on to extract dirty water and grime from the floor.

This also allows ‘right to the edge’ cleaning, alongside walls and into corners, along skirtings, under furniture and around fixtures. A range of easily interchangeable brushes are available to suit any particular floor surface surface from carpets to hard flooring.

The Duplex 420 Floor Cleaning Machine is remarkable-it gives outstanding results on all floor surfaces and washes, mops, scrubs, dries and polishes all surfaces to an exceptionally high standard.

The Duplex 420 Floor Cleaning Machine has brushes which are offset to one side and the machine’s bi-directional handle allows cleaning in both directions with no lifting involved.

Unique features

  • Bi-directionality: its innovative design and manoeuvrability allow the user to reverse the Duplex '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 cleans under furniture, along the wainscoting and in hard to reach corners.
