I love my new shark ion vacuum its amazing cleans up cat hair and all the dirt I am able to run my vacuum from my phone and it has a charger I plug into the wall and I can dock my vacuum and it charges it truly is the best vacuum i ever owned it picked up so much cat hair I didn't even realize was there and it has a bump censor and it can redirect itself so it didn't get stuck also if I put down the magnetic strips it keeps the vacuum from areas that could be dangerous like under furniture or by wires and plugs. If you need a vacuum cleaner that runs on its own and you can control through your phone and cleans your house amazingly this is the vacuum for you.
