- Bi-directionality: its innovative design and manoeuvrability allow the user to reverse the Duplex 420’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 420 cleans under furniture, along the wainscoting and in hard to reach corners.
