This is my first cordless vacuum so I was skeptical about its power and run time. Our lab has been shedding like crazy and we just found out that my husband is allergic to pet dander and dust. We needed a quick and easy solution for vacuuming every day and this provided exactly that. The amount of hair and dust this picks up is crazy! We plug in the battery at the end of each day and have never had a power issue. So happy with this purchase and would highly recommend.
