  1. Dolphin 300i Is Wonderful

    The dolphin 300i is easy to use, does a great job getting your pool clean in no time. It's able to pick up small particles trapping them in the many filters along with larger debris. Cleaning the basket is easy. The only downfall I see is it does not get the seams at the corners completely clean.

  2. Premature Review

    I've only had my S300i for a week. Just got it set up and used it one time. The directions for sssembling the caddy could have been better but was finally able to complete. The dolphin did a great job on a pool that had not been vacuumed for three weeks. Cleanup was fast and easy. I love it, but less see how it continues to perform.
