The B 90 R range provides simple, highly productive scrubbing and drying in a compact ride-on package.

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
