ONEPWR Cordless Vacumn
[This review was collected as part of a promotion.] This is awesome. Great suction, long lasting battery to vacuum a 2000 SF home. I wanted it for the dog fur that piles up daily. It was difficult to always bring my corded vacuum out daily. this ONEPWR is awesome. Picks up dog fur with ease. Of course it is not for deep cleaning but for me to get all the fur up; it is awesome. I would highly recommend it.
