Is a fun design ...

1. So loud it is definitely. If you have kids who sleep level, and you even want to quickly soak up the crumbs that goes before garnicht .... Since even the neighbors are awake by the noise.
2.OFF the openings on the sides so is a tornado - out air flow that he stirs up all the dust and there is nothing left to suck ... -D. The larger crumbs that are too heavy to fly are, of course 1A sucked.

So the suction definitely good (this explains the tornado comes out of it). About 5m cable, one should not complain, as the cup was probably intended for small suction surfaces and not durchzusaugen the whole apartment. And Vorrteil to Akkusauger, the suction power will not diminish over time (zmnd. Should not :)).
So for the price, one can press the minuses an eye.
