The Dolphin Proteus line is Maytronics' simple, do-the-job pool robot family — plug-and-play cleaning that scrubs the floor and climbs the walls, with a programmable weekly timer so it runs on its own schedule. No booster pump, no hoses, no assembly.

All three Proteus models — the DX3, DX4, and DX5i — are corded cleaners for inground pools. Every one is shown below with live pricing; our pool experts compare them further down. Want waterline cleaning and NanoFilters™? Step up to ProLine™ or the Max-Series.

Dolphin Proteus DX3

The Dolphin Proteus DX3 is a straightforward pool cleaner suitable for inground pools up to 33 feet, focusing on scrubbing floors and walls. However, it does not offer waterline cleaning or NanoFilters, limiting its effectiveness in capturing finer debris and algae. While the DX3’s Plug'n'Play functionality provides easy setup, the lack of advanced features, such as an anti-tangle swivel, makes it less appealing compared to newer, feature-rich alternatives. For users needing a thorough, uninterrupted clean, this model may not meet higher performance expectations.

Dolphin Proteus DX4

The Dolphin Proteus DX4 offers waterline scrubbing and includes an anti-tangle swivel, making it a more advanced option in the Proteus lineup. Designed for pools up to 40 feet, it has high-speed scrubbing brushes but lacks NanoFilters, which limits its ability to capture finer particles. While it provides energy-efficient motors and a weekly scheduling feature, it still does not support smartphone connectivity, which some users might find restrictive. Comparable models with more advanced filtration and control options may offer better value for those seeking top-tier cleaning performance.

Dolphin Proteus DX5i

The Dolphin Proteus DX5i features waterline cleaning and anti-tangle swivel technology, along with high-speed brushes for enhanced pool coverage. Although it offers convenient Plug'n'Play functionality, the lack of multiple filtration options and limited warranty may be drawbacks for users who require robust, long-lasting solutions. Suitable for pools up to 50 feet, the DX5i delivers efficient wall and floor cleaning, but the absence of a smartphone app and more advanced filtration capabilities may leave some users looking for a more feature-rich cleaner at a similar price range.
