The SBD 650-3 is no longer available. A similar substitute is the SBD 285-3 Combination Floor Tool.
The Miele SBD 650-3 AirTeQ Combination Floor Tool is an energy-saving floor tool that is ideal for homes with carpets or bare floors. Switch from carpets to bare floors by pressing the foot pedals on the floor tool itself to engage or disengage the bristle strip. The metal soleplate and rubberized wheels glide smoothly over all your surfaces.
