Dolphin Nautilus AG Above-Ground Robotic Pool Cleaner

The Nautilus AG is the most reviewed cleaner on this entire page by a wide margin, and it holds a strong average across all of them. For above-ground pools it's the safe, boring, correct answer.

The review record

Thousands of reviews at a 4.4 average is a different class of evidence from the double-digit review counts on most newly launched cordless robots. It tells you how the machine behaves in its third season, not its first week — which is the question that actually matters.

Gentle on liners

Above-ground pools are almost always vinyl. The active scrubbing brush is designed to be tough on dirt and gentle on the surface, which is the specification you want when the alternative is scouring a liner you can't refinish.

Smart Navigation

It scans the pool and computes an efficient path rather than bouncing randomly. On a round above-ground pool that's what gets full floor coverage inside a 1.5-hour cycle.

Where it stops

This is a floor cleaner. If you want walls and waterline on an above-ground pool, the Dolphin Escape in our own range is the model built for that job.
