What features does it have?
The Dolphin Proteus DX4 brings reliable, wall-climbing cleaning to your pool without the complexity of hoses or booster pumps. It's a practical pick for keeping your water consistently clean. Below, we cover its features and how it fits into the 2026 Dolphin lineup.
Wall Climbing
Clean like a pro. With wall coverage, the Dolphin Proteus DX4 can clean and scale your walls with precision and power. While Wall Climbing is a great feature, don't get this confused with the superior waterline cleaning feature.
What is Dolphin Proteus DX4 missing?
Waterline Cleaning
Dolphin Proteus DX4 does not included waterline cleaning. Not only is this an essential feature that you'll want when looking for a pool robot, but one you will likely need. Waterline cleaning enables the robot to climb and reach the dirtest part of your swimming pool. Without this feature, you'll still need to manually clean your waterline by hand with a brush to prevent any algae or scum that builds up. It is one feature that you'll need that is not included with the Dolphin Proteus DX4.
Leaf Bag
With leaves being a common issue, it would be safe to assume most pool robots utilize a leaf bag. Well, no so fast. Nearly every robotic pool cleaner is missing a leaf bag, except the Dolphin Premier. If you have a lot of leaves, this is the best pool robot for leaves. Not to mention the Premier's 3 year warranty, Dual Commercial Motors, and Multi-Media™ make it one of the best models available.
It's worth noting the Proteus DX4 relies on standard filtration rather than NanoFilters and sits below the ProLine and Max-Series tiers. If top-tier filtration and commercial-grade power matter to you, a ProLine cleaner such as the Dolphin Premier or a Max-Series model is the natural upgrade.
What's included with the Dolphin Proteus DX4?
The Dolphin Proteus DX4 includes everything you'll need. Here is what is included with the unit:
- Dolphin Proteus DX4 Unit
- 60 ft Cord with Anti-Tangle Swivel
- Programmable Weekly Timer
- Standard Filters
- 2 Year Warranty
How to set up the Dolphin Proteus DX4
Simply plug and play. All robotic pool cleaners are ready to go right out of the box. No booster pump or assembly needed. The Proteus DX4 has everything needed to get started in its box. It's that easy.
