The Shark AI Ultra 2-in-1 Robot with Self Empty XL has changed my life! The setup was super easy and the instructions were clear and easy to understand. In just a short time I was setup and ready to clean. I love the self cleaning brush roll. I live in a home with people who have long hair and and pets so that is a super important feature to have. The matrix cleaning ensures that nothing is left behind. I love that I’m able to clean my home with a press of a button and I don’t have to be there. The app is super easy to use too.
