The B 90 R range provides simple, highly productive scrubbing and drying in a compact ride-on package. The B 90 R features Kärcher’s interchangeable brush head system, making 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 three formats - the Classic model offering fixed settings for ease of use, the Advanced model featuring variable suction, brush speed and contact pressure, and the Advanced Dose model featuring Kärcher’s Dose detergent metering system
