The all new SBB 400 3XL twister floor tool is a super sized version of its predecessor, the SBB 300-3. The extra large dusting radius allows you to clean much larger areas at a time. Its two soft rollers and genuine horse-hair bristles are well designed to thoroughly clean tiled and wood floors. The 400 3XL has a 90 degree rotation and is exceptionally agile when cleaning around obstacles such as tables, chair legs and much more. This product is a fantastic new addition to the Miele family of fine products.
