The powerful drive, which even helps to overcome inclines with ease, is one of the most striking features of our BD 80/100 W Classic Bp Pack walk-behind scrubber drier. The hand-held and battery-powered device has a very robust design. For example, heavily used components such as the squeegee and disc brush head are made of solid and durable aluminium. The tried-and-tested operating concept with the spring clip on the back of the handle, the simple increase in brush contact pressure from 40 to 68 kilograms for particularly stubborn dirt or for decoating, and the continuously adjustable transport and cleaning speed of up to 5 km/h are very convenient for the user. The large working width of 80 centimeters and the 100 liter tank enable long and efficient cleaning operations and area performance of up to 4,800 m² per hour. The new 160 Ah strong lithium-ion battery with extremely high cycle stability and the possibility of intermediate charging ensures maximum machine availability, and with a charging current of 50 amps the battery can also be charged much faster.
