Thanks to a new generation of brush heads, the new B 90 R scrubber-dryer comes in up to 72 different versions. Users can also opt for roller brushes or disc brushes in different working widths - even after purchasing the machine. The entire brush head can be replaced in just a few minutes without the use of tools. Three versions of the machine are available: The basic “Classic” model operates on a fixed setting, so even inexperienced operators can make almost no mistakes. The “Advanced” model can be adjusted on site where required. The “Advanced DOSE” model features the ability to add a precise dose of detergent when needed.
