I'm very satisfied with the sucker. For a handyman he does good services. If you want to suck up fine dust, the use of a vacuum cleaner bag is recommended. Although cost something, but it also fits some pure. Anyone who wants to avoid the bag-buying, often must the filter manually turn down, but this is quick, uncomplicated, but also caused some dust. The built-in automatic filter cleaning delays the dust from hand but a little is not a substitute, for. Suction is good overall, at 1800 watts but would still expect a little more. Suction hose could have an air slide, so that the suction power can be ggf.dosiert. Suction can be maneuvered well and not easily tip over. Opening the rather large collection container is easy. Overall ease of use. Water I have not yet absorbed. In my view, price and performance here in good agreement. The professional at the site probably needs a better machine that he is, however, not get for the price.
