Karcher B 40 W BP

Walk-Behind Floor Scrubber

The B 40 W with traction drive scrubber features: a 10.6 gallon fresh and recovery tank-in-tank design, interchangeable modular disc or cylindrical roller scrubbing heads, 33.5” vacuum squeegee and Kärcher’s Intelligent Key system. The KIK system enables the facility manager to create a unique cleaning profile, making it easier to train users and operate the scrubber. KIK is used to set varying levels of authorized access by means of color-coded keys; yellow, grey and red; for operators, facility managers and technicians, respectively. Facility managers can set parameters such as travel speed, brush speed, motor output or cleaning solution output to suit the needs of the cleaning task. An operator’s key carries out the pre-determined settings, needing only to select their desired cleaning program from a rotary knob. As a result, only the required amount of energy and cleaning agent is used.
