The Miele SBB 400-3 Parquet Twister XL floor brush is an upgraded version of the Miele SBB 300-3 brush, having a wider cleaning path of 16 inches as compared to the 12-inch one of its predecessor. Some floor brushes have natural bristles, but this floor brush does not. It has natural boars hairs instead, which are gentle and firm at the same time. It also has rubber wheels which do not leave any marks on the floor. A mixture of polyamide and natural hair ensures a gentle cushion for this floor brush which makes sure that tile, wood and other smooth surfaces are cleaned thoroughly with extreme care. As far as the design is concerned, the knuckle construction of this floor brush makes it agile enough to reach any virtually unreachable areas. Its twister neck allows it to sneak around obstacles of any kind like furniture corners, thresholds and so on. This twister neck, which can be angled at up to 90 degrees, sets the 400-3 floor brush apart from other parquet floor brushes or hard floor brushes manufactured by Miele which may indeed be available for lower prices but which are less maneuverable and agile. The SBB 400-3 Parquet Twister XL floor brush provides thorough cleaning on a variety of hard floors such as marble, bamboo, granite and many more. It is also a very good cleaning solution for delicate floors such as ceramic floor or laminates ones.
