Kärcher

The B at a glance

Kärcher’s B scrubber dryers wash, scrub and dry a hard floor in a single pass. The family runs from compact walk-behinds for workshops and smaller industrial floors to ride-ons for warehouses, production halls and car parks. Most take disc or roller brush heads, to suit smooth or textured floors.

Heads, squeegees and dosing

The roller heads on the B 110 R, B 150 R and B 200 R pre-sweep coarse dirt into a drawer while they scrub. Squeegees are die-cast aluminium with Linatex suction lips, and they give way on contact with a wall. Speed-responsive dosing cuts the water flow in bends and at low speed.
