I am running the beta firmware for the robotic vacuum. I upgraded to it a while back because of this same issue, hoping it would fix the problem. Alas, the same issue arose yesterday. The vacuum is set on a schedule to automatically run each week (not sure if this plays a factor). I heard it sounding like it was having an issue and upon checking it was stuck under our desk. This is an area where I placed a virtual wall. I pulled up the map, and sure enough, the original had rotated 45 degrees. The virtual walls stay in the same place, thus it gets into areas where it gets stuck. I submitted logs for the incident.
Also please note - I went to submit a support ticket, however the Vacuum is not a product listed that you can report a problem with… The site shows the cameras etc, but not the vacuum.
