The suction power is generally very good, but sit down after a short time booze and hair on the inner cone from pink. If you have about 60 m2 sucked, you have to clean the inner screw definitely, otherwise he no longer sucks. While this is fairly simple, but you might have spared himself the large dust container, since it does not even begin to fully is before the screw is clogged. 3 stars, because the handling and cleaning is relatively simple and convincing the suction line in the purified state.
