This Miele AllTeQ is a combination tool with a top mounted lever to switch between carpets and bare floors. For bare floors a brush strip around the perimeter pops out to provide non-scratching brushing action. Notches along the front allow dirt to easily enter the nozzle. For carpets and rugs, the brush strip is recessed, allowing the channeled steel sole plate to contact the carpet, pulling air through the nap to clean it. This attachment has a long tab on its elbow to mate with the parking slots on the Miele S2, S4, S5, S6, S8, C1, C2 and C3 Series canister vacuums.   For similar products see our list of Miele Vacuum Accessories.
