I had a pleasure to use this machine, and must say that it was a bit disappointing. Suction was good but it wasn't really moving easily on the carpet.
The worst was emptying though. The bin seems to be made of a really cheap quality plastic, you could basically easily bend it and you've got the littlest handle to hold it while opening.
I find Big Balls bin much better and much easier to empty, those machines seem to be much better in my opinion
