My Roomba 780
comes with two 810-lighthouses. But the lighthouses only work as virtual wall, even if I flip the switch on it to Lighthouse.
I even tried walling the roomba in, then setting a lighthouse at a door entrance in lighthouse mode. Then the Roomba avoids the room with the same mechanic as if it was set to virtual wall.
I'm starting to wonder if my Roomba is broken in its logic, or if it is my lighthouses that’s the problem.
Here's a vid showing the behavior:http://youtu.be/SbztwC_5DL4
