Sunken Living Room

Our living room is 4” below the surrounding rooms.  Although our robot has mapped the room, it cannot reach it because of the drop.

What is the best strategy for running the robot in the living room?  If I just put it there, I think it will clean the room without a problem.  It will not, however, be able to get back to its base for water, and charging.

Suggestions?

You can add a ramp and then add it to the map as a virtual ramp.
