Spec-based review: scored from Maytronics Dolphin's published specifications with the same weights as every other robotic cleaner. Not a hands-on test. How we score.

Our take

The Dolphin Nautilus CC Robotic Pool Cleaner is a corded robotic pool cleaner from Maytronics Dolphin. It cleans the floor and walls, navigates in a systematic pattern rather than at random, using CleverClean, and has no app.

On paper it scores 6.0 out of 10 (fair) against other robotic cleaners. Its strongest areas are runtime (8.5) and navigation (7.0). Where it gives ground: app & connectivity (2.0) and warranty (4.0). Climbs walls but doesn’t scrub the waterline.

The best price we found is $699 at Maytronics Dolphin (US). The typical robotic cleaner we track costs $899, so this one is cheaper than most. For what it does, its value score is 4.6 out of 10.

If you want mapping navigation, the cheapest we track with it is the Dreame Z1 Cordless Robotic Pool Cleaner at $349.99.

If you want a Wi-Fi app, the cheapest we track with it is the Dreame Z1 Pro Cordless Robotic Pool Cleaner at $399.99.

To spend less for nearly the same spec score, the WYBOT C2 Cordless Robotic Pool Cleaner (2026 Upgrade) rates 8.4 for $429.

For about the same money, the Beatbot Sora 10 Robotic Pool Cleaner scores higher (8.4) at $469.

Bottom line: a fair pick for above-ground pools.
