This is the coolest robot vacuum! The app was easy to download and works really well.  The app contains a lot of cool features.  Such as, tracking square footage or area already cleaned.  You can control the robot vacuum through the app by changing cleaning pattern or setting times/days to automatically run the vacuum.  You can also change the suction through the app and use the ionizer.  The different levels of suction are great for different flooring types.  The vacuum itself is not very noisy.  The suction power is great, as the tray was nice and full with dirt and grime.  The vacuum maneuvers nicely around objects and continues on it's cleaning path.  I totally recommend purchasing one!
