I love my shark ultra!!! It’s so easy to set up and get cleaning. The app guides you thru the set up process and house mapping. This shark whom I named Downey is so smart are found it’s way all around my downstairs which was fascinating to watch. Once we were mapped and labeled we were ready to vacuum. And away Downey went! I almost felt lazy watching him do all my work. Next up I easily attached the mop attachment which the app showed me how to do and my whole downstairs was magically cleaned. Fast, efficient, easy and I’m in love!
