I bought my Aquavac because I currently renovating an old attic. Since a lot of dirt to fall, sometimes with moisture. So far I have the Aquavac not used as pure wet vacuum cleaner. As a normal part of the vacuum cleaner but already works really well. The suction power is, in comparison with other parts of the same high-performance, very good. The volume is higher than in a "normal" house vacuum cleaner, it is still in a tolerable range. As another reviewer already wrote, the stainless steel container is really good made. Too bad that only a paper bag is included and also is very sensitive (they tear relatively quickly). I try to use the Swirl Uni 20 and hope that the work better.
