So, now for Rowenta:
I would have gladly given 5 stars, but there are unfortunately still find fault. The front air sucked comes back side out again and then blows before, what you really want to soak away.
Otherwise, I am very satisfied. The suction power is excellent. The charging time is pleasantly brief 6 hours (the Dirt Devil 16 hours). Can fully charge you suck about 15 minutes. The slider to turn snaps into position, so you do not have to hold him. He also is lighter and handier than the Dirt Devil.
However, most excites me the large triangular brush. I've almost always better: sometimes just suck the wooden staircase, or quickly on the tiles in the bathroom. I even get the dog hair out of the carpet.
Meanwhile, I've bought a second battery vacuum cleaner - one for each floor. Considering Hab long, which model should be. Recently I had to decide between the Fakir LHN 18 Black / Chrome Battery vacuum cleaner 'and described here Rowenta. Unfortunately, the fakir had only a mini brush, so I have now a second Rowenta.
