The SEBO power head is made for the K3, D4 and Felix 1 models. It is 12 inches wide, with a 10.5 inch cleaning path. It has a four-level manual brush height adjustment. It agressively cleans carpets, but the brush roller may be switched off by pressing the green illuminated on/off button, so delicate rugs and hard floors can be cleaned with straight suction. Its amazing 180 degree steering ability provides maneuverability around furniture and the extension side of the L-shaped head makes cleaning edges and under counters easy. It also has easy brush roller removal, a convenient clog removal door and an orange warning light with automatic shut off for brush roller obstructions.
