I bought this accessory together with the Dyson DC52 Animal turbine, driven by the substantial moved my two German shepherds "long hair". Unconvinced to buy (because having tried moult brushes or devices "dépoilants" ...), I told myself at the time that, considering the price of the vacuum cleaner, I could spend another 29 for a gadget additional. Upon first use, I was hooked! Remarkable efficiency! (I already made some emulators ...) Two points still to be specified: 1 - The "hair" metal are quite fragile in the sense that they can quickly twist, brush always good straight line to not twist, which could impair the function of "exit-withdrawal" of the brush. 2 - Gradually acclimatise dog vacuumed before the first brush in the coming cajoling look a treat near the vacuum cleaner while it is operating, with lyrics and reassuring attitude, and several days. If you do not do this and your dog becomes frightened, it will be damn long time to brush it with this accessory and a hassle when he hears the vacuum cleaner running. He must associate the vacuum cleaner something pleasant as the treat.
