"Works wonderfully. Named him "Flipper" and he does a GREAT job. I love that I can put him in and walk away to do other things and know that after 2-3 hours my pool is super clean and ready to go." -Cindy Lindeman, WI

"I have used Dolphin cleaners since 2003. That Dolphin served me well for 12 years without a problem. The time came to replace the cleaner. My decision was easy. I purchased the Dolphin M500." -Jerry Filippone, IL

"I watched the model in the tank at the place where I get my water checked for about 2 years. It looked amazing but I could not afford to buy at that time. The business then started to rent them out and I was hooked! No other pool cleaner grabbed my attention like the Dolphin." -Tracey Ellis, VA
