I have had a Dolphin Automatic pool cleaner for over ten years. I just had a problem recently with belt coming off. I was noticing not moving as fast as when I first purchased it. I want to repair it and keep as a back up. Just purchased new pool cleaner Polaris. This works well only thing doesn't run as long as the dolphin.when purchasing new belts what else should I buy for dolphin that could be worn as well as the belts.
