This app is worthless. I paid way too much for a robot vacuum that doesn't even have a functional app. The map resets every time I open the app. I got this so I could have it clean certain rooms downstairs (gotta love golden retriever hair), but since the map resets, it just cleans randomly around the downstairs, missing all kinds of spots. The app worked for a short while, but now it only opens half the time and won't save my map. We won't be purchasing any more shark products.
