Hello. I am absolutely satisfied with the device. Compared with my previous vacuum cleaner with 2300 W (Siemens) he is actually quiet, although he's still loud. Compared to the previous vacuum cleaner it is also really powerful, despite the great difference in the wattage. A friend who is professionally active in the cleaning of buildings, however, is not convinced by the performance. I would buy the little ones definitely go back, maybe then the number is larger. It delivers what it promises. If you were accustomed to working with a "normal" vacuum cleaner, you realize how much time 20 L capacity at all. In wet eyes so far I could not test it, but with or without a bag, everything went well. What I like is that he does not like a wind makes my old appliance.
