Product Review · Robot Pool Cleaners · #8 Ranked
Dolphin Nautilus AG
Corded floor-only robot for above-ground pools · Reviewed by Katie · amazon.com live, Sept 24 2026
Why it scored a 79
The Nautilus AG is the safe, plug-in choice for above-ground pools, and it scores 79 on Reliability 90, Quality 88 and Satisfaction 88 from 6,385 ratings at 4.4 stars. It is corded, scans the pool to plan its path, scrubs with an active brush and finishes a cycle in about 1.5 hours, with a top-load filter for easy emptying. The catches: it cleans the floor only, not walls or the waterline, so Features sits at 66, and $568.00 is a lot for a floor-only robot, so Value is 76. Maytronics lists a 1-year warranty, which scores 55.

Should you buy the Dolphin Nautilus AG?
The Dolphin Nautilus AG is for an above-ground pool up to 33 ft whose owner wants a corded robot that just works and is happy to brush the walls by hand. At $568.00 it ranks #8 of 10 in our Robot Pool Cleaners category. The Aiper Seagull SE 2025 costs far less at $147.98 but sits under our buy line; the Beatbot Sora 30 costs $131 more and adds walls, waterline and cordless operation.
Where it earns its score
- Proven owner base. 6,385 ratings at 4.4 stars, the second-deepest record here after the Dolphin Nautilus CC Plus.
- Corded, no charging. Plug in, drop it in and power on; a cycle takes about 1.5 hours with no battery to wear out.
- Active scrubbing. A spinning brush scrubs the floor while smart navigation plans the path for any shape or surface.
- Top-load filter. The basket lifts out from the top for quick emptying.
What to know first
- Warranty is the lowest factor at 55. Maytronics lists a 1-year warranty for the Nautilus AG, half the term of most cordless rivals here.
- Floor only. Dolphin states it does not clean walls or the waterline, so those still need a brush.
- Size and naming. The listing rates it for pools up to 33 ft while Maytronics says 30 ft, and this Amazon page once sold the Dolphin E10, so older reviews may describe that model.
Our verdict
The Dolphin Nautilus AG scores 79, a Fair Buy and #8 in our Robot Pool Cleaners category, carried by Reliability (90), Quality (88) and Satisfaction (88). Buy it for an above-ground pool if a corded, floor-only Dolphin covers your needs. If you want walls and waterline too, the Beatbot Sora 30 (85) handles above-ground pools for $699.00.
