In the world of robotic pool cleaners, few names carry the same weight as Maytronics Dolphin, and two of its most efficient in-ground models—the Dolphin Proteus DX4 vs Dolphin Triton PS—frequently stand out among discerning pool owners. These cleaners are both powerful, reliable, and packed with features tailored to meet the expectations of modern residential pool maintenance.
Although they appear similar in terms of size and structure, they offer key differences in filtration design, navigation intelligence, and cleaning effectiveness. Below is a detailed, structured comparison to help you determine which robotic pool cleaner best suits your needs.

Differences Between Dolphin Proteus DX4 vs Dolphin Triton PS
Below is a summary of the specifications:
Design Comparison
The Dolphin Proteus DX4 and the Dolphin Triton PS are both designed for in-ground pools up to 50 feet, featuring 60-foot swivel cables that allow tangle-free navigation during cleaning cycles. Their low-profile bodies are optimized for effective wall climbing and precise maneuverability.
The Proteus DX4, weighing 20 pounds, has a solid, durable exterior and is built for tough debris conditions. Its design includes a robust top-handle, and the cable management system is excellent, thanks to the integrated swivel technology.
On the other hand, the Dolphin Triton PS is lighter at just 16.5 pounds, making it easier to carry and lift, particularly for elderly users or anyone looking for a lightweight model. Despite its lower weight, it still maintains a sturdy design with excellent grip and handling for pool entries and exits.
Winner: Dolphin Triton PS
The Triton PS wins for users prioritizing lightweight design and portability, though both offer equal pool size compatibility and cable performance.
Cleaning Performance Comparison
The Dolphin Proteus DX4 is equipped with dual active scrubbing brushes that rotate independently to maximize debris removal from pool floors, walls, and especially the waterline. Its 4000 GPH suction power allows it to pick up both large and fine debris efficiently. It uses a dual-layer top-load filter basket combining fine and ultra-fine filtration, which captures a wide spectrum of contaminants—from large leaves to pollen and silt.
The Dolphin Triton PS features a single front-mounted high-speed PowerStream brush that works effectively at scrubbing dirt off all surfaces, including tiles and vinyl. It also offers 4000 GPH suction, but it comes with a single fine filter basket, which means it may allow ultra-fine debris to pass through unless upgraded with optional filters.
Both units have a 2-hour cycle time, offering full pool coverage with internal scanning algorithms that help them avoid overlap and missed spots.
Winner: Dolphin Proteus DX4
The dual active brushes and layered filtration system give the DX4 superior scrubbing and debris collection, especially for pools with finer particles or heavy organic buildup.
Feature Comparison
The Dolphin Proteus DX4 includes a built-in weekly scheduler that allows you to set it to clean daily, every other day, or every third day. This feature removes the need to start the cleaner manually, though all controls are handled via the power supply. It does not offer Wi-Fi or mobile app integration.
The Dolphin Triton PS offers a similar weekly scheduler, also accessed from the power supply. Like the DX4, it lacks any kind of smart connectivity or remote operation. Both models use Maytronics’ scanning logic to map the pool for efficient navigation, but neither includes gyroscopic mapping or Bluetooth control.
Where they differ is in user experience with filter access and cleaning. The DX4’s top-load dual-layer basket is easier to clean and handles more debris without frequent emptying. The Triton PS filter is top-loading but lacks the dual-layer design, requiring more frequent maintenance in high-debris pools.
Winner: Dolphin Proteus DX4
While both have the same automation features, the DX4’s filter technology makes it more practical and efficient for hands-free pool cleaning over time.

Conclusion
Choose Dolphin Proteus DX4 if you want a powerful, versatile robotic pool cleaner with dual active brushes, fine + ultra-fine filtration, and maximum cleaning performance. It is the better choice for pool owners who experience a variety of debris types or want more aggressive scrubbing action for algae and biofilm.
Choose Dolphin Triton PS if you prefer a lighter, easy-to-lift model that still delivers reliable cleaning for floor, wall, and waterline. It’s an excellent option for those who want a basic but dependable cleaner without the need for enhanced brush or filtration systems.
Overall Winner: Dolphin Proteus DX4
With its advanced filtration, stronger scrubbing brushes, and better debris-handling capabilities, the Dolphin Proteus DX4 stands out as the more complete and performance-driven robotic cleaner for comprehensive pool maintenance.
