We have a 27ft ABG pool. Got tired of spending so much time vacuuming it so we bought a Dolphin Atlantis robotic cleaner. We LOVE it. Drop it in and 3 hours later take it out. It is worth every penny we paid for it. Most stores that sell them will let you take the store model home for 24 to 48 hours for a test run if you want. We didn't because we didn't want to put something in our pool that had been in someone else's in case they had algae or other problems. Would definitely buy this model again.
