Portability Comparison
The Dolphin Proteus DX3 is slightly bulkier, measuring 22 x 18 x 13 inches, while the Dolphin Proteus DX4 is more slimline, with the same height but being 0.5 inches taller and 0.5 inches narrower. Despite being slightly heavier by 0.5 pounds, the DX4 still looks more polished and easier to store than the DX3.
One of the key features of the Dolphin Proteus DX4 is the anti-tangle cable, making it more user-friendly to carry and store, whereas the DX3 is lacking this feature, making it susceptible to tangling and potentially damaging the cable, which results in a shorter lifespan of the product.
The DX3, on the other hand, boasts a cable of 50 feet, whereas the DX4 is limited to a 10-foot cable.
Power Comparison
Compared to cleaning performance, the DX3 can handle depths of up to 33 feet, and the DX4 can efficiently clean swimming pools as deep as 50 feet. Thus, the DX4 is better suited for larger and deeper swimming pools.
The filter type on both devices is the same, but the DX4’s basket is larger, allowing for the collection of more debris, making it the winner in this category.
Both robotic cleaners feature a high-speed front scrubber, but the DX4 has an added standard back scrubber, allowing for more thorough cleaning of the pool.
The Dolphin Proteus DX3 and DX4 have a comparable cleaning speed, both taking roughly 2 hours to complete the task.
With plug-in functionality, Dolphin cleaners save money on additional equipment and have a longer lifespan, while also being more energy efficient than other options on the market.
Features Comparison
The Dolphin Proteus DX3 and DX4 lack smartphone and connectivity capabilities, making it impossible to control and manage them with your phone. Unlike other modern robot cleaners, these models do not have smartphone capacities.
The Proteus DX3 offers a weekly scheduler feature that allows users to set a cleaning schedule in three modes: daily, every other day, or every three days. In contrast, the Dolphin Proteus DX4 only offers one standard cleaning time, which is a significant disadvantage.
Conclusion
In our view, the Dolphin Proteus DX4 is the superior choice over the DX3. We are confident that the DX4 will effectively remove the buildup of algae from the winter and spring seasons in a short amount of time. Additionally, it is more lightweight, simple to clean, and more efficient at removing debris from the bottom of gunite/ Pebble Tec pools. The DX4 also boasts a Front High-Speed Scrubber and Standard Back Scrubber, which work together to improve the overall clarity of pools.
