For starters EVERY time you open the app you have to login with your user name and password... Really, for a vacuum cleaner..?.?...   Another surprise, you can only "map" and "label" one level, Roomba maps multiple levels, if I had known that one feature wasn't available than I would not have bought the shark.  Another complaint is the integration with Google Max Hub, IF you command the shark with your phone only then it works but when my Max Hub picks up the command then it doesn't recognize the shark being connected. It appears to be trying to command a different shark model (not the one we bought) and then says that the shark cannot be found.  The machine itself seems to be ok and works as designed.  I hope after time shark will update the software and make it more user friendly.
