Since I have the whole house hard floors, I bought this for my brush vacuum cleaner from Siemens. Delivery is very fast. Since the floor brush made a very cheap impression after the first visit, I was at first not sure if it could be an Asian replica this product. However, because the packaging had a sticker from Siemens with the correct product and serial number of this brush, I assume that this is an original accessory. As mentioned above makes the brush at first glance a very cheap, simple and bit quality impression, which, however, again the selling price benefits, and belies the actual processing. Because the brush is handled quite properly and the plastic used is of good stability and very robust. The suction result can actually nothing to be desired. All dirt which may occur in a household is, literally smoothly sucked away. What I am also arrived at the actual purpose of this brush. Sucking hard floors such as wood or tile. This works pleasantly low noise due to the long and stable brush hairs. Unlike the standard brush to fly formally without much effort on the ground. Of course, can be produced by the design of the brush hairs, carpets very difficult to suck. But that is not the area of application of this brush. I am extremely pleased with this accessory and do not regret the purchase.
