The Kehrer met not even begin the job. We wanted a device that is suitable for parquet. But that can not be said of this unit. The housing scrapes and grinds at the bottom, so you have to have more concerns that the parquet floor wearing a damage it. The dirt on the other hand remains lie. After several back and forth a crumb moving time into the case. When opening for emptying one is faced with the next challenge. This is quite rigid and not very easy to use.
I can not understand it, why a company like Leifheit brings such a device to market. It has 0% value and 100% creates credibility. In future I think about, again a device from the home to buy Leifheit, I have to call into question the credibility and feel lied to me.
