The B 90 R range from Kärcher brings a new level of flexibility and value to scrubber driers. As well as several improvements over the BR and BD Trike machines the range replaces, the B 90 R features Kärcher’s new interchangeable brush head system. This makes it possible to purchase one machine and choose between roller or disc brushes in different working widths, with the option of retro-fitting a different brush head to better suit another application. The B 90 R is available with a brush disc or roller head in 65cm width, or optional 75cm width. As well as four head options, the machine is available in two formats – the Classic model offering fixed settings for ease of use, and the Advanced model featuring Kärcher’s DOSE detergent metering system and variable suction, brush speed and contact pressure.
