What features does it have?
The Dolphin Proteus DX5i offers easy, automated cleaning with the added convenience of smart control, so keeping your pool clean is as simple as pressing a button. Here's a closer look at what the DX5i does well and where it lands in 2026.
Wall Climbing
Clean like a pro. With wall coverage, the Dolphin Proteus DX5i 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 DX5i missing?
Waterline Cleaning
Dolphin Proteus DX5i 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 DX5i.
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.
To set expectations, the Proteus DX5i doesn't include NanoFilters and isn't part of the ProLine or Max-Series lineup. For the absolute best filtration and commercial-grade motor power, consider a ProLine cleaner like the Dolphin Premier or a Max-Series model.
What's included with the Dolphin Proteus DX5i?
The Dolphin Proteus DX5i includes everything you'll need. Here is what is included with the unit:
- Dolphin Proteus DX5i Unit
- 60 ft Cord with Anti-Tangle Swivel
- Programmable Weekly Timer
- Standard Filters
- 2 Year Warranty
How to set up the Dolphin Proteus DX5i
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 DX5i has everything needed to get started in its box. It's that easy.
