I have purchased it for my new fireplace. Unfortunately, I gave up after two repeated use. The unit is extremely loud, which would be more disposed to suffer, but the filter was to 2x suck too, so it no longer works. It is recommended here auspinseln and rinse it. Unfortunately tapping is not because of the dust sits very firmly in the filter. Auspinseln lasts forever and rinse dirty the entire bath - not recommended. I use since then whisk broom and dustpan.
Unfortunately, a return was not, as was stated that I get refunded only 70% of the purchase price. Together with the delivery it's worth no more. I feel that at the point as impudence from the shipper
