I have this thing now for 2 days, and am. Fully satisfied with the performance. Even at a low extraction level, he still sucks good (cigarette ash, small wood chips, etc.). The cleaning funzt simply, the kind-snap clean the filter I find also very thoughtful. But: The unit is very noisy. My Siemens vacuum cleaner with 1600W is, however, a "Flüstergerät". I'm the piece as far as possible so not to use at night to be able to continue to live with my neighbors in peace. For persons living alone (homeowners) certainly the best device.
