Our old vacuum cleaner was not broken - but the noise did eventually just annoyed. We have a new device searched with the top priority that it should be as quiet as possible - but of course this also has good suction, because this is, after all, the whole point. We opted ultimately for Siemens. After a few weeks' probation "We are pleased with our choice more than satisfied - that makes vacuuming again (almost) fun. The vacuum cleaner is really very pleasantly quiet. For the daily evening through eyes (mainly cat litter, lint, hair) the lowest level do just fine - and here are we and our cats to enjoy a really pleasant quiet engine noise. In addition, the sucker is agile, easy to use, looks good and holds also pleasant to (high quality finish) and another plus is the super long cord. If you choose Other Essays (upholstery nozzle, etc.) then the sucking sound actually much louder - louder than the motor. We think however that this is probably just can not be avoided in the current state of the art, and - as I said - the standard daily use, which accounts for 90% of use certainly, yes, this does not apply. The only shortcoming that certainly does not apply to everyone but: The bottom piece is significantly higher than that of our old vacuum cleaner, etc. so we hereby no longer come under it in some closet, cabinet edge, Sofa. Therefore, we have now gained us the parquet brush - so happy you again. All in all, therefore: strong buy recommendation!
