Only visually good

The device is very cheap ............ that's the positives. The installation is simple and straightforward by hand, self-explanatory.
The vacuum cleaner itself is very noisy, because one wants to achieve a proper suction power. If you push the Watt controller to the center position, the yellow devil sucks below average, but still quite noisy bearable. But if you want an even reasonably satisfactory suction power, so you need full suction and so overwhelmed you the little devil actually the engine whines in the flashiest shades. This keeps you so about 5 minutes ............. or about as long as it takes to suck a small, not narrow apartment. Then you're glad to be able to turn off the breaker.
I also only 2x times sucked the dirt devil, so very empty bag; as the suction power changes with full bag, I can not say. But it is assumed that a slowing suction.
Even for the price it is expensive and I would advise everyone to spend a few euros more for a quieter and saugstärkeres Maschinchen.
Supplement May 2013:

The suction power is close to zero. You have to keep the nozzle directly over the crumbs, so that the devil himself after some deliberation deigns him to the attention, that is it included in the vacuum bag.

In addition, the front wheel is broken from the cheap bracket and the sharp edges because I had not noticed the damage me my newly sanded wood floor with ugly scratches has provided.

I strongly advise against purchasing this literally to be taken little devil!
