We owned this vacuum for a couple of years. It's a great little vacuum. It effectively picks up dog hair off of rugs, and we use it frequently in between major vacuuming to touch up. After a while, the batter started not lasting as long. That seemed reasonable after a couple of years, so we ordered a new battery. The new battery was great, for about a month. Now it won't charge at all. The light on the charger doesn't even come on when it's inserted. I've tried all of the recommendations (unplug charger, wait 30 seconds; put battery in vacuum, turn on, wait 30 seconds). Nothing works. The charger still charges the old battery, but it now only lasts a couple minutes. The battery problems are very disappointing. This would have 4-5 stars, if not for the battery problems.
