Efficient cleaning in large commercial facilities

A Duplex 620 is a large floor scrubber that thoroughly cleans floors simultaneously washing, agitating and extracting in a single pass. At 620mm in width the Duplex 620 is the widest model in the Duplex floor scrubber range and is perfectly suited for efficient cleaning in large commercial facilities. Despite the large size this machine is incredibly easy to use and highly maneuvrable.

The Duplex 620 floor scrubber is packed full of features and best of all there is basically no set up time. Simply fill the two solution tanks with water, select the height setting, pull back the handle and start cleaning. It is that easy.
