I needed something easier to maneuver than the upright and canister vacs that I usually have.  I also didn’t want to have to drag a cord all over the house and changes outlets. I have hardwood floors with a couple of small area rugs. I can vacuum my whole downstairs on ½ a charge (about 1100 sf). When I’m done, I fold it up and plug it in for the next time.  With two medium sized shedding dogs, I vacuum at least once a day.  This little powerhouse has really saved time, aggravation, and my back and shoulders!  So far, my only complaint is that I wish the dust cup was bigger.
