The suction power is adjustable through a regulator. I have it mostly at half strength. This is efficient enough and the noise still portable. In the upper third, he is already very noisy, I must admit. That was not so pleased.
I have now tested the vacuum cleaner a few weeks and am really excited about the suction power. The vacuum cleaner has dirt pulled out my carpet that I just could not believe it. I once drove all carpets (and there are not many) and the container was filled with about 1/4 dust and crumbs. When I think how many times I was on this carpet, yuck!
Even animal hair (in my case, cat dander) removed the Dirt Devil like a champ. Finally, the sofa is back hair free. This was not possible with the old bag device. Suction is a smooth 1!
Cleaning:
Just the container empty, fluff filter cleaning, may hold times under the tap and then install directly again. 5 minutes and it can go on. Unbeatable!
Handling:
The vacuum cleaner rolls nicely behind and travels without mucking and grumbling about his cable. But what really bothers me: The aluminum intake manifold is attached to the handle made of plastic. There is no snap, and it happened to me constantly that loosens the pipe and also gladly times throughout rausflutscht. I have the pipe already on it stuck with all their might, it stopped again suck 2-3 times, but was again loose. This is a shame and that bothers me personally also most of the device. Maybe I have since gotten even a Monday model.
Conclusion:
For me, the vacuum cleaner is but a very strong buy recommendation. Register here for price and performance. It does not always draufstehen Dyson :)
