I'm in the market for a robotic cleaner for my new fiberglass pool. It's a 16x40 and has a 6-8" ledge that goes around the whole deep end which starts when the floor starts to slope. Below is what the pool looks like with the ledge. I want to make sure the cleaner can go up the full wall in the deep end without falling off when it gets to the ledge. Does anyone have this situation and if so, which cleaner have you found to work the best to overcome the wall ledge. Also, how well does it clean with rounded inside edges?
