Duplex – One for All Floor Machine

Over the years, Duplex has been popular in the market especially when it comes to floor cleaning machines. Why?

Perhaps the reasons why Duplex floor machines tops cleaning industry are the important features and advantages of its floor machines. These generally apply to all its roller brush machines:

1.    Duplex floor machines are suitable for all floor cleaning jobs, not only for deep cleaning or stripping like the single disc machines, but also for maintenance cleaning and for polishing.

2.    As it is a scrubber-drier, Duplex has a vacuum system and fresh /waste water tanks; therefore you don’t need a separate wet vacuum cleaner as with other floor maintenance machines. It can be switched between a scrub only function or a simultaneous scrub / vacuum function.

3.    Duplex operates with roller brushes. They have a contact pressure that is 6 times higher than disc-type brushes and they rotate 10 times faster, which results in a much higher efficiency.

4.    Roller brushes not only perform well on smooth surfaces but also on studded rubber floors or non-slip tiles because they have the ability to scrub deep into profiles.

5.    Duplex floor machines work in both the forwards and reverse directions and are neutral in its movement that gives many advantages. For example, most people will be able to operate the machine without fatigue. It scrubs equally well across the total working width. It gets right into corners and close to edges. The cleaning solution is kept within the track and is not splashed. You can work with only a small overlap of the tracks which saves time.

6.    Duplex floor machines are very compact and lightweight hence, it can be carried by one person. The handle collapses for transportation and the machine can be easily loaded into the trunk of a car.

7.    It can also be used for the vitrification / crystallization of terrazzo and marble, an entirely new application for this kind of machine. Normally, this work is done with heavy single disc machines at a very slow pace and it is very expensive. Today, it is possible for everybody to perform this task at a comparatively low cost and very quickly.
