One of tge best, most high end vacuum robots I have ever owned. The shark ultra 2 in 1 robot is not your average vacuum, it exceed my expectations. What makes it even easier to manage it is the very simplified app. Super easy to follow, and to chose the areas where the robot should be vacuuming or mopping. It is a life saver! All I have to do is within a click of a button. It's super powerful, does the job and cleans AND mopps. And when done, goes back on the dock to recharge. I love every single details in the Super awesome shark robot. Ultra amazing!!
