I love it! And now with the new updated "smart mapping", the vacuuming should be more efficient. The app itself is easy to navigate. Edit: I just changed it from 5 stars to 2. It just spent 1 hour and 40 minutes creating a "smart map". I then went to direct it to clean a specific room and it's telling me I need to create a smart map in order to do that. So all that noise and making sure EVERYTHING was out of the way so it would make the best map was a complete waste of time.
