Hi there, we are getting our pool renovated with new PebbleTec, tile, and coping next week, and were planning on continuing to use our "Dolphin" cleaner/vacuum for pool upkeep. But the dolphin has these two long rubber rollers with lots of little rubber flaps that sort of "scrub" the walls. It's great for "brushing" the walls of the pool (it climbs), and does a great job, but does anyone know if this will sweep the stones our of my PebbleTec? Is it safe to have something that crawls and brushes the PebbleTec, or do I need to (no, no, no please...) vacuum the pool instead?

If you have a PebbleTec pool, what do you use to keep it clean and swept (besides Polaris...gave up on that years ago)? Thanks!
