The Miele SBD 350-3 FiberTeQ Classic Combination Floor Tool has been discontinued. A similar substitute that will fit all models that used the SBD 350-3 is the SBD 285-3 Classic Combination Floor Tool.
The SBD 350-3 has a push lever that lets you control whether you want to use the tool on carpets or bare floors. There is a brush strip along the front and squeegee along the back to allow you to gently clean your bare floors without scratching the surfaces. Notches along the front of the brush help guide the dirt to the nozzle. The brush strip and the squeegee are recessed when using the carpet and rug setting and the channeled steel sole plate makes contact with the carpet and pulls the air through the nap to clean it. The soft rubber wheels allow the tool to move smoothly over your floors without scratching the surface.
