Dolphin Proteus DX5i
Corded Wi-Fi robot with waterline scrubbing · Reviewed by Katie · amazon.com live, Sept 24 2026
Why it scored a 77
The Proteus DX5i is Dolphin's corded Wi-Fi robot, and Quality 88 and Features 88 are its case: always-connected scheduling through the MyDolphin Plus app, wall climbing, waterline scrubbing, an active brush, a top-load filter and a rated 4,000 GPH on pools up to 50 ft. It scores 77, a Fair Buy, because $1,199.00 buys a lot elsewhere (Value 66) and owners are cooler on it than on other Dolphins: 4.0 stars over 257 ratings gives Satisfaction 78 after the low-volume deduction. The 2-year warranty is a year longer than current Nautilus models.

Should you buy the Dolphin Proteus DX5i?
The Dolphin Proteus DX5i is for an in-ground pool up to 50 ft where you want a corded Dolphin you can schedule from your phone anywhere. Maytronics also lists it for above-ground pools. At $1,199.00 it ranks #9 of 10 in our Robot Pool Cleaners category. The Dolphin Nautilus CC Plus gives you the same corded reliability for $829.00 without Wi-Fi, and the cordless Beatbot Sora 30 scores higher at $699.00.
Where it earns its score
- Wi-Fi scheduling. Always-connected Wi-Fi and the MyDolphin Plus app let you set a weekly timer and start cleans from anywhere.
- Waterline scrubbing. It grips the walls and scrubs the waterline, not just the floor.
- Big-pool rating. Rated for pools up to 50 ft, with a 4,000 GPH suction rate and a 2-hour default cycle.
- Corded, no charging. A floating cable means no battery to fade and no downtime between runs.
What to know first
- Value is the lowest factor at 66. Tied with Warranty, it reflects a $1,199.00 price that is $370 more than the Dolphin Nautilus CC Plus, with Wi-Fi as most of the difference.
- Cooler owner ratings. 4.0 stars over 257 ratings trails the 4.3 to 4.4 other Dolphins earn, so Satisfaction is 78.
- Warranty is 2 years. Maytronics lists 2 years for the DX5i, a year more than current Nautilus models but short of the Beatbot AquaSense 2 Ultra.
Our verdict
The Dolphin Proteus DX5i scores 77, a Fair Buy and #9 in our Robot Pool Cleaners category. Quality (88) and Features (88) are real, but Value (66) and Satisfaction (78) hold it back. Buy it only if Wi-Fi scheduling on a corded Dolphin matters to you. Otherwise the Dolphin Nautilus CC Plus (83) is $370 cheaper and better rated.
