Certainly the best upright vacuum cleaner, we have ever had. No doubt he is loud, but as the saying goes, lawnmower, shavers and vacuum cleaners are only good if they are noisy :-)) This seems to apply well. Other reviews I can only complement; there were complaints that the power switch can not be established. This I think does not matter, because the device must anyway in hand held and the switch is just right there.
For short battery life: I can not negative, because it is supposed to a hand vacuum cleaner for small cleaning jobs to be, not a sucker for the whole living room.
