I love the battery life. I use it twice a day!!We have to small dogs that are “hypoallergenicâ€....However, l run this twice a day and it sucks up so much dog hair.It almost grosses how much dirt and dog hair builds up in a few hours.I’m a clean freak—I enjoy waking up to a clean floor.If you’re hesitant about buying DO IT!Think of how much time we spend sweeping or vacuuming.. I have more time to do things I enjoy because it’s cleaning for me.You won’t regret buying this shark!The only thing I would suggest- do a good vacuum before you use it. One—it starts off with a clean slate.. Two— you’ll be amazed how much you missed. It’s also goes under hard to reach places.TREAT YOURSELF!You’ll be so glad you did it.
