The Miele STB 205-3 Turbo Comfort Turbobrush has been discontinued. The STB 305-3 TurboTeq TurboBrush is the appropriate replacement.
The STB 205-3 is air-driven and is ideal for low to medium pile carpeting. It has an 11" wide roller brush that loosens dirt from the carpet. There is a bumper strip around the Turbobrush that protects your walls and furniture from scuffing. There is an adjustment slide on top of the Turbobrush that you can adjust for use on hard floors or loose rugs.
