Scrubber drier B 250 R I + R 120

The battery powered B 250 R I + R 120 combo ride-on scrubber drier with eco!efficiency mode is characterised by sophisticated roller technology with 120 cm working width and sweeping function.

The B 250 R I + R 120 combo ride-on scrubber drier has a practical sweeper, which makes time-consuming preliminary sweeping superfluous, and a 120 centimetre wide roller brush, whose speed can be optimally regulated in 3 stages for each cleaning situation thanks to FACT function. The large water tank (250 l) and the durable battery (36 V/630 Ah) guarantee long work intervals, whereas a round filter and the automatic filter cleaning make possible dust-free work. The machine, which is available in several configuration options, is very easy to operate thanks to colour-coded operating elements, EASY Operation switch and a large colour display for setting and adjusting the cleaning modes. Operating errors are largely ruled out with the KIK system. The eco!efficiency mode reduces turbine power, water volume and roller speed at the touch of a button – at the same time the runtime is increased by around 20 percent. As an option, the machine can also be connected to Kärcher Fleet, our cloud-based fleet management system. With this system the machine can be monitored in real time and, for example, its utilisation can be optimised.
