I was watching my Dolphin tonight and turned off the wall climbing. It covered a much smaller area of the pool.

You've been watching yours a lot more than I've seen mine but it seems that the only real progress to new turn is when it hits the surface and craps along the waterline.

The amount of time it spends there seems to be tied to the size of the pool you tell it you have. I think it calculates the time to cross it and adds some for water level cleaning and crabbing along the edge to new territory.

If your unit will climb the walls to the surface, try going up one size on the set up mode and see what happens.
