M400 provides highly efficient pool cleaning for pools up to 50ft in length. Advanced systems ensure accurate scanning for systematic coverage of floor, walls and water-line, leaving clean and hygienic water throughout.
Dolphin’s patented swivel cables eliminate tangled cables forever!
As your Dolphin moves around the pool, the swivel ensures that the cable stays free and clear, allowing for complete pool coverage.
Advanced scanning software and gyroscopic navigation system ensure floors and walls are fully covered using the most efficient route. The Dolphin automatically navigates around obstacles and quickly returns to its cleaning pattern.
Dual drive-motor for optimal pool maneuverability and coverage, regardless of shape, slope and obstacles.
Dual-level filtering ensures clog-free operation in any pool conditions. Use the net filter at the start of season to clear rough debris; for regular use, catch fine and rough dirt with the ultra-fine filter cartridge.

"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
