Frequently Asked Questions
What type of machine is the Karcher B 300 RI LPG?
The B 300 RI LPG is a combination sweeper-scrubber. It can sweep debris, scrub floors, and vacuum dirty water in a single pass. This dramatically increases cleaning productivity in large facilities compared to using separate sweepers and floor scrubbers.

What types of facilities typically use this machine?
The B 300 RI is designed for very large facilities including warehouses, airports, manufacturing plants, transportation hubs, and large institutional buildings where sweeping and scrubbing must be completed quickly.
