Dolphin Premier
The Dolphin Premier is acclaimed as the best pool robot by USA Today, highly regarded by both experts and pool owners. Its standout feature is the Multi-Media™ system, offering an unmatched range of filter options, including a unique leaf bag designed for pools with heavy leaf debris. This model is user-friendly and equipped with Media-Alert for real-time filter tracking. Enhanced with commercial-grade motors, NanoFiltration™, and waterline cleaning capabilities, the Dolphin Premier is a flagship model in the ProLine series, offering a blend of essential and advanced features. However, it is an investment but well worth it - especially with a longer 3 year warranty.
Shop Dolphin PremierDolphin Quantum
The Dolphin Quantum combines power and user-friendliness, featuring a MaxBin™ that is easier to clean and includes NanoFilters. It stands out with its PowerJet 3D Mobility and HyperBrush, ensuring thorough pool coverage and superior filtration. This top inground Dolphin pool cleaner is also part of the ProLine series, offering features like waterline cleaning and a weekly timer.
Shop Dolphin Quantum
Dolphin Sigma
The Dolphin Sigma is noted for its advanced technology, including a gyroscope and SmartNav 3.0™, powered by three commercial-grade ProLine™ motors. This makes it highly efficient in pool cleaning, with a triple commercial-motor design that impressed our pool experts in their testing. The Sigma is easy to use, controlled via the myDolphin Plus app (even utilizes Siri Voice Control), and includes NanoFiltration™. While it is one of the most expensive Dolphin robots, it does include the longer 3 year warranty as well.
Shop Dolphin SigmaDolphin Cayman
Recognized as the best value Dolphin pool robot, the Cayman is a part of the Max-Series™, featuring MaxBin, Wall Climbing, and even optional NanoFiltration. It offers essential features like a weekly timer and extraordinary cleaning abilities, making it a top choice in 2026. It lacks waterline cleaning and commercial-grade motors, but still provides the best cleaning performance we have ever seen at this price.
Shop Dolphin Cayman
Dolphin Escape
Ideal for above-ground or small inground pools, the Dolphin Escape is built on the Max-Series™ platform, equipped with a MaxBin and HyperBrush. Ranked the best above ground Dolphin pool robot, the Escape is a top pick from our pool experts. Its HyperBrush actively scrubs the pool floor at double the speed of the unit, ensuring thorough cleaning. This highly-efficient cleaner gets the job done and impressed us in its testing.
Shop Dolphin EscapeDolphin Liberty
As a part of the new Dolphin Liberty Series, the Dolphin Liberty 200 is the best cordless robotic pool cleaner available. Suitable for situations where an extension cord can't reach, it still falls short in performance and filtration compared to corded models like those in the Max-Series and Dolphin ProLine. This model is recommended for specific cordless cases, as it is more expensive with less features.
