Professional steam floorwasher

The Duplex 420 Steamplus, Floor Steam Cleaner, with a cleaning width of 420 mm (16″), gives ‘right to the edge’ cleaning on all floor surfaces, alongside walls and into corners.

Steam is supplied to one of the contra rotating brushes and therefore floors are left sanitised and virtually immediately dry.

Its supporting panels and entire structure are in die cast aluminium, while the accessory housing is impact proof and the brush holder panels are made of stainless steel.

The 130° jet of steam, directed onto the floor, makes it easy to remove even the most stubborn dirt.

The machine is also supplied with standard fluid tanks, allowing it to be used in steam or fluid cleaning mode as required. A range of different brush types to suit different types of flooring are available.

The Duplex 420 Steamplus is great on carpets, tiles, wood, marble, vinyl, Timbersafe, Flotex, Marley, carpet tiles, safety floorsresin floors and many more.

Unique features

  • Effective and extremely easy to use: steam is particularly good at cleaning fabric surfaces such as carpets and carpet tiles, since it does not wet the fabric and revitalises the fibres.
  • It is equipped with two tanks: one acts as a boiler, while the other holds and dispenses the water. The machine can also be used as a conventional floorwasher with detergent solutions.
  • 130° steam jet: makes the most stubborn dirt easy to remove.
  • Total cleaning of even the most challenging areas of the floor: the Duplex 420 Steam Plus cleans under furniture, along the wainscoting and in hard to reach corners.
  • Bi-directionality: its innovative design and manoeuvrability allow the user to reverse the Duplex 420 Steam Plus's direction simply by inverting its handle. This "about face" makes it easy to clean from right to left/forwards and backwards and vice-versa - especially in restricted spaces.
  • Perfectly balanced: compact design, centrally located brushes and tanks, centrally positioned motor.
