duPLEX 14" multi- surface cleaning


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 heavilysoiled 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.



Multifunctional, professional: the Duplex is particularly effective for thoroughly cleaning medium sized spaces such as hotel rooms, kitchens, offices and hospitals.


The Duplex® brand, a byword for efficiency, identifies machines with innumerable advantages for cleaning and sanitizing your floors to best effect.
3 application solutions: wash only, wash with recovery, and polishing.


In normal use, the Duplex is an automatic floorwasher: it dispenses the liquid, washes the surface and immediately recovers the dirt.
If the floor is particularly dirty, simply flipping a lever turns the machine into non-recovery floor washing machine.
The cleaning fluid is recovered at a later stage when the lever is returned to its original position.


Two larger diameter cylindrical counter-rotating brushes

The energetic action of the two patented cylindrical brushes, rotating in opposite directions at 650 rpm (peripheral speed of 5 m/s), assures effective mechanical washing. 
The Duplex brushes are larger than conventional floor cleaning brushes, so that they rotate at a faster peripheral speed which greatly reduces cleaning times.


Dual liquid dispensing (one head per brush)

The two washing solution tanks wet both brushes at the same time for highly effective results in both directions.


Dual dirt recovery system

The machine is equipped with sophisticated and safe dirt recovery system employing special transport belts.


Unique removable tanks

The liquid tanks are easy to remove when necessary, since they are not blocked by the valve cables; they are easy to clean, while the dirt recovery tank is located at the centre of the machine with two special scrapers which gather all the solid and liquid waste.


Versatile application

the Duplex 420, when fitted with special optional brushes, can also be used for removing wax and encrustations, and polishing and degreasing

  • 4 working positions: for dealing with any surface, carpet tile, wood, pvc, cotto, ceramic tile, stone and so on.

  • Removable brushes: the hex wrench included with the machine makes it a snap to remove and replace brushes in just a few seconds.

How the Duplex Floor Washing Machine Works

To start the machine simply lower the handle slightly. Pull the trigger to release water and detergent. Cylindrical brushes flick dirt onto rotating belts which carry it to a central recovery tank. This tank is easily removed for emptying. To stop the machine simply raise the handle back to the upright position.


Unique Features:

Dual-direction: the original design and versatility of the Duplex allows bi-directional cleaning. With the brushes working to the edge on one side, a fluid movement to change handle position allows cleaning up to every edge without having to lift or turn the machine.  

Thorough floor cleaning, even in the most hard to reach areas: under furniture, along skirting boards and in corners.  

  • Two large contra-rotating cylindrical brushes  
  • Liquid distribution for each brush  
  • Double dirt recovery system  
  • Removable recovery tank
