I was very surprised after I tried it for the first time, because the day before I had done a complete cleaning in the room. I do not regret the purchase, I am very satisfied. Its pros: Really very quiet. High suction power. Compact. Technologically logical in the process - assemble / disassemble. Cons below: It is not customary to use the suction power adjustment using a sliding flap on the tube that you hold by hand. Although from a technical point of view, this is a plus - the absence of an additional engine speed control circuit.
