I’m enjoying this robot vacuum.  This little helper allows me to tackle other tasks while it’s vacuuming for me. It navigates the room it is vacuuming pretty well.  I wish it were better at moving from one space to another.   The app can be better.  I don’t feel that the map in the app provides an accurate description of where the vacuum and where it traveled during the course of cleaning.  I also found that the vacuum had a hard time finding the base.  I hoping both of these will improve over time.  On the positive side, vacuum responds quickly when using the app.
