Dolphin Nautilus CC Plus Robotic Pool Cleaner

Our take

The Dolphin Nautilus CC Plus 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, and has no app.

On paper it scores 6.2 out of 10 (fair) against other robotic cleaners. Its strongest areas are pool size (10.0) and runtime (8.5). 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 $829 at Maytronics Dolphin (US). The typical robotic cleaner we track costs $899, so this one is about average. For what it does, its value score is 3.5 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 AquaSense 2 Robotic Pool Cleaner scores higher (9.0) at $799.

Bottom line: a fair pick for large pools.
