5 Best Dolphin Cordless Pool Cleaners

The Dolphin M600 is a robotic pool cleaner designed for inground pools up to 15 meters in length, making it a great fit for most residential pools. It offers impressive cleaning coverage, reaching the floor, walls, and waterline thanks to its water jet propulsion and smart navigation technology that helps it move around efficiently without missing spots. The advanced brushing system with multi-layer brushes is effective at removing stubborn dirt and debris from all pool surfaces. One of its strong points is the large filter capacity with dual filtration (fine and ultra-fine), which means less frequent emptying and better trapping of even tiny particles, leading to a sparkling clean pool.

The cleaner connects via Wi-Fi and is controlled through an app, allowing you to schedule cleaning cycles and customize settings for convenience. Despite being corded electric, it features a swivel cable design to prevent tangling and comes with a caddy for easy transportation and storage. Weighing 11.5 kg, it’s relatively lightweight for a robotic cleaner, though this might feel a bit heavy when lifting it wet. The cycle length can be controlled via the app, giving flexibility in cleaning schedules. A 3-year warranty adds peace of mind about its durability. While it requires a nearby power connection and some attention to cable management during use, the advanced features and thorough cleaning justify the higher price compared to simpler models for those seeking automated pool maintenance with minimal hands-on effort.

The Dolphin S400 is a corded robotic pool cleaner designed for medium to large inground pools up to 15 meters long. Although it’s not cordless, its 18-meter swivel power cable offers good range without tangling, which helps keep cleaning uninterrupted. It cleans the floor, walls, and waterline thoroughly using CleverClean navigation and PowerStream mobility technology, ensuring your pool gets covered well. The brushes actively scrub all surfaces, removing dirt efficiently.

This model offers flexible cleaning cycle lengths from 1 to 2.5 hours, so you can choose a cycle that fits your pool’s needs or your schedule. Using the MyDolphin Plus app, you get convenient remote control with features like weekly timers and delay starts, making it easy to set and forget your pool cleaning. The filtration system is multi-layered and top-loading, capturing both fine and coarse debris with a large capacity, which means less frequent filter cleaning.

Weighing 7.5 kg, the S400 is relatively lightweight and comes with a sturdy caddy to make transport and storage hassle-free. Its build quality is solid, and the 4-year warranty gives peace of mind for long-term use. While it lacks the cordless flexibility, it remains an ideal choice for pool owners seeking a powerful, high-tech, and easy-to-use robotic cleaner that provides extensive coverage with smart navigation and app control. If you don't mind the cord and want thorough cleaning with strong scheduling options, this is a reliable option.

The Dolphin M400 cordless robotic pool cleaner is designed for pools up to 12 meters and works well on rough surfaces like quartz or pebbles. It uses smart navigation with dual motors that help it move efficiently across the floor, walls, and waterline, ensuring thorough cleaning coverage. Its triple scrubbing brushes are powerful enough to remove algae, dirt, and debris, leaving the pool spotless. One of its strengths is the dual filtration system, which includes fine and ultra-fine cartridges that capture both large and tiny particles, making it suitable for regular maintenance or heavier cleaning tasks.

The 18-meter swivel cable minimizes tangling, which makes operation smoother, and the included caddy adds portability despite the unit’s relatively heavy 11 kg weight. The Dolphin M400 connects to Wi-Fi and can be controlled remotely via an app, allowing you to schedule cleanings and monitor progress easily from your phone. Since it is mains-powered rather than battery-operated, it doesn’t offer cordless convenience, which could limit flexibility if your power outlets are not close to your pool. Its weight might make handling slightly challenging for some users, despite the caddy helping with transport.

If you have a rough-surfaced pool and want a smart, thorough cleaner with strong scrubbing and filtration, the Dolphin M400 is a reliable choice, especially if you value app control and don’t mind a mains connection.
