I ran into this issue when I changed to the newer updated cable that came with a smaller float. Mine keep getting stuck on it's side where the pool floor and stair walls meet. It happens in shallow water. I took the old floats off the old cable and installed it on the Nautilus CC plus and has never got stuck since then. You can test out my theory by Zip tying an empty water bottle on the power cable. You can adjust the buoyancy by adding water into the bottle. You want to position the bottle under the water line where it would pull the cable up in a straight line with minimal slack. This assists the robot in staying up rather than on its side. Try it and post back your results. Maytronics's customer service is worthless. I've used a number their products for the past 12yrs, they performed well when they are 2yrs new, after that, 3 to 4 years go by, they start malfunctioning. They won't help troubleshoot how to fix the issue, they only refer you to their service centers which are also worthless.
