Once again i am going to ask for advice in the awesome forum. I am looking for recommendations on an automatic pool cleaner for a 30,000 gallon pool with plaster and fiberglass wall kit. Salt water pool.
I would get a robotic pool cleaner. My pool is similar in size to yours and I have a Dolphin Supreme M400. It works great for me. I can't speak for other brands, but if you get a Dolphin, buy from a store and not online as the online models do not offer a warranty (at least they did not the last I checked).
My dolphin just died a few days and I replaced it with a polaris 9450 sport. So far its been amazing way easier to clean out and use then the dolphin was and it picks up everything. Made opening the pool a breeze this year
