Bought the vacuum cleaner according to the good rating from Stiftung Warentest. We had until now a bagless of AEG.Dieser was very loud and sucked getting worse. The assembling of Siemens was easy and I was surprised even the light weight of the sucker. The next surprise was the first Einschalten.Das's a vacuum cleaner I can Flüstersauger.Den make garnicht to full power because it is so tightly drawn on the carpet, I no longer get it moving. Super suction !!! Actually, I was set out bagless vacuum cleaner. But when I see what the cost and the noise and the mess every time when emptying. Since I prefer to buy back anthers. I was pleasantly surprised by the length of the power cord. In the last suckers were much shorter. The vacuum cleaner also runs very easily afterwards so he also recommended for people who do not have is a lot of strength. In short, I can recommend the Siemens VSZ31455 !!!
