Product Overview
The Kärcher B 50 W Bp walk-behind scrubber is designed for fast and efficient wet cleaning of floors and hard surfaces. It offers advanced cleaning technology in a compact design, delivering impeccable results over areas up to 18,200 square feet. Available with either the R55 cylindrical brush or the O51 orbital brush, both models enhance efficiency and ease of use. The machine features durable cast aluminum construction for the brush head and squeegee assemblies. The parabolic squeegee ensures excellent water recovery, even on uneven surfaces and in tight turns. An integrated AGM battery provides ample power for extended operations, and the wheel-drive system reduces operator fatigue.
