Our last was a vacuum cleaner Miele S-Class. He has served no less than true 15 years. He does still, but some stairs crashes have then battered him something. So, a new was needed. My wife wanted the test winner of Stiftung Warentest 2013/14 for the half, almost 1 / 3Value, a corresponding Miele vacuum cleaner .. First Impressions: * Extremely high suction power at full capacity, the center position is dramatically better than the full capacity at peak Miele. * Very quiet - he purrs. The cats are afraid even before this silent stage. * Really good is the very long cables, now I suck even where I often times to comfortably wait for the Umsteckens the cable that I enjoy. * A very light and handy device. It runs better and more easily than the Miele. * Value? I suspect once this device does not live as long as the Miele. The transition from the hose to the intake manifold seems to be inevitable in my opinion a short lifetime. That's better! Since Siemens could overtake with this truly outstanding unit Miele, when the long-term quality is right. Unfortunately, now is the following common: Good quality for a short time boosts the economy. I, as a consumer wants good quality for a long time! Purchase Date: 6/2014. I will, if necessary, report on the first failures. Conclusion: So far, this vacuum cleaner is more than highly recommended! And for the new device I give a full purchase recommendation! Longevity: ??? If he creates 10 years I was very pleasantly surprised by this unit, even more: love it!
