Maximizing the efficiency of the RoboVac

We’re absolutely in love with our RoboVac, but have found that there are a few things we just can’t seem to figure out. Most of all, I’ll come downstairs in the morning and find it stuck under the couch. We’ve tried raising the couch up using furniture movers, and it works for the most part, but I’d be curious to see what tips and tricks everyone has used to make sure that their RoboVac starts, runs, and returns home every day.
