This thing is amazing! The battery is enough to clean 3 floors of the house. I cleaned the upstairs staircase as it is the only place in my house that has carpet. This thing collected all the dog hair. It's lightweight but doesn't feel cheap. Easily folds and stores under the bed and cradle. I highly recommend this vacuum cleaner! I usually get itchy and runny dog hair when vacuuming, but with the HEPA filter I've found I don't have that problem. love this vacuum.
