The Dolphin Max-Series
The Best Pool Robots
Updated for 2026, the Dolphin Max-Series delivers on perfecting pool robots and their performance. The Dolphin Quantum, Cayman and Escape are equipped with a Gen-2 MaxBin® and all include NanoFiltration™ compatibility.
These new 2026 pool robots clean like never before, with no restocking fee ever. And when you're ready for the top of the line, the Dolphin Sigma adds an onboard gyroscope, triple commercial-grade motors and quad scrubbing brushes.
The largest cartridge ever in a pool robot
Larger Than Ever Before
The new Sigma's filtration system is so large, easy and convenient, you'll never consider messy, cumbersome debris bags again. Cartridge filters have been around for years, but pool owners found them small and difficult to clean. Consider this problem solved.
With the new Sigma, Dolphin introduces a new massive top-loading cartridge with the highest capacity ever recorded on a pool robot.
