I never knew how much I needed this purr air robot vacuum until I got it and used it. I do not like sweeping so that is why I decided to get this vacuum and I love it! I get my floors cleaned fast and never have to put up a broom. It also has air purification and a remote! It usually lasts for about 40 minutes to an hour before I need to recharge. I usually just empty it and put it away once the battery runs down and place it on the charger for next time. This is so convenient and saves me so much time!
