    I’m extremely impressed with the performance of this vacuum. I have not had any clogs from pet hair and I love the feature of it automatically dumping into a canister versus having to dump it each time.

    This isn’t my favorite vacuum. It doesn’t last a long time. The suction is very good in the beginning and then wears out overtime.

    No, I would not recommend this to a friend

    I’ve owned two other model battery operated vacuums from Dyson and Levoit, so far this is the best I’ve used. It picks up everything as well as my corded, the dust bin is a nice touch. The battery on the highest setting lasts about 15 minutes. This picks up everything really well for the price and I can’t honestly think of any complaints that would warrant knocking a star off.

    Seems to clean well. I like that it cleans the tank on the vacuum when you set it on the charger. Says that the dump the bin that it doesn't go everywhere...it doesn't AS MUCH as others, but it still can make a mess.
