Its suction is certainly good, but it's less convenient in almost every single way than a regular vacuum with a hose and what-not.
It doesn't get into corners or edges or under furniture as well and it's much less convenient to store, not to mention being so noisy that I have to wear earmuffs when I'm using it.
Also, the build quality is not stellar — if I pick it up by its carry-handle, it falls apart, and there's no straightforward way of fixing that.
D-, would not buy again. If I could find the receipt, I'd be taking it back for a refund.
