The TORQUE DRIVE electrobrush monitors the resistance on the cleaning brush shaft (360 samples per second) and automatically adjusts the power of the device to the type of surface to be vacuumed. Thanks to it, it is possible to thoroughly clean both the carpet and the substrate with much harder characteristics, without having to change the cleaning tip. The replaceable shaft is equipped with black anti-static carbon fiber and rigid nylon bristles. Shaft Color: Nickel Plated
