Convenient while it lasted.. which wasn't long..
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.The fact that it empties itself is convenient but it has been barely over a month and the cheap plastic handle which is hollow and thin broke! My wife was vacuuming and all of a sudden calls me over all upset because the handle was snapped in half with wires showing. Im not sure if maybe ours had taken some damage in shipping or if the handle just happend to be compromised somehow but for something that you are supposed to push arround, turn and lift (with attachement) to reach corners, you would expect the handle to be reinforced or a little mor solid but after seeing the inside its not very thick at all. My wife has other opinions and preferred our older shark vacuum vortex something or other over this one but i tried to defend it because i kiked that i didnt have to empty the canister so often and it seems to get clogged less but i expected to last more than a month and change. Not sure what to do here but for now i taped and glued it hoping it can hold hntil i get a replacement but not sure what i can teust anymore. This wasnt a cheap vacuum to be breaking so easily!! Ill happily change the review if I had a model that lasted longer because it could easily be 4 or 5 stars not for the flimsy handle.

Frustrating
||Posted . Owned for 2 months when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.I have a small area rug in the living room and tile floors. If you have kids and pets, this is not the one for you. If you just have dust and a little dirt now and then, it's perfect. By far the worst cordless vac I've owned, I gave it the benefit of the doubt for 3months. It will clog within the first 2min of usage due to the 1/2" inlet at the brush side of it. Very frustrating just pushing dirt around. I've owned much cheaper Amazon brands that did a much better job. Make sure to spec out the size of your inlet tube before purchasing a portable vacuum. The self cleaning option is all I like about the unit.

Terrible suction
||Posted . Owned for 1 week when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Horrible suction. This is a complete waste of money. Always had decent luck with shark products but this one is a complete flop.
