Quick Answer: “Nautilus CC” is Maytronics’ family name for its CleverClean-navigation robotic pool cleaners, and it covers three tiers: the base Nautilus CC (about $599, floor-only), the Nautilus CC Plus (about $749, floor + walls + waterline, Maytronics’ best-seller), and the Nautilus CC Supreme ($1,149 sale / $1,449 list, adds a third motor and stronger suction). For most inground pools up to 50 ft, the CC Plus is the one to buy — it covers the full floor-walls-waterline job at the best price, and independent testers agree the pricier Supreme rarely earns its premium on an average residential pool.
If you searched “Dolphin Nautilus CC” hoping to find one specific robot, here’s the short version: there isn’t just one. Maytronics uses “Nautilus CC” as an umbrella name for a family of corded robots that all share the same CleverClean navigation pattern, and the suffix — nothing, “Plus,” or “Supreme” — is what actually tells you what you’re buying. Below is the plain-English breakdown of each tier, real 2026 prices, and which one fits your pool.
The Nautilus CC family at a glance
| Model | Cleans | Motors | Wi-Fi | Price |
|---|---|---|---|---|
| Nautilus CC (base) | Floor only | 1 | No — weekly timer | ~$599 |
| Nautilus CC Plus | Floor, walls, waterline | 1 | Yes (current model) | ~$749 |
| Nautilus CC Supreme | Floor, walls, waterline | 3 | Yes | $1,149 sale / $1,449 list |
Dolphin Nautilus CC Plus
- Cleans floor, walls and waterline of inground pools up to 50 ft.
- Corded — unlimited runtime, nothing to recharge.
- Wi-Fi + MyDolphin Plus app on the current model.
Robots this size usually ship freight, which can mean a multi-day wait — a free 30-day Amazon Prime trial can get one on your deck faster, and you can cancel before the trial ends if you don’t plan to keep it.
By the numbers
- Price spread: The three tiers span ~$599 to $1,449 (per Maytronics US), roughly 2.4x between the cheapest and priciest Nautilus CC — a wide range for models that share the same core navigation pattern.
- Suction jump: The CC Supreme’s three motors deliver 4,500 GPH, per Maytronics’ own spec sheet and confirmed independently by Robotic Reviews — notably stronger than the single-motor CC Plus, though that extra pull is the Supreme’s main upgrade over its cheaper sibling.
- Independent score: Robotic Reviews scored the CC Supreme 83/100 overall but rated its filtration “Bad” for shipping without NanoFilters — a reminder that a higher price tier doesn’t automatically mean a better-reviewed filter system.
- Coverage: All three models are rated by Maytronics for inground pools up to 50 ft — the tier you pick changes what gets cleaned and how fast, not how big a pool the robot can handle.
What “CC” actually buys you (and what it doesn’t)
The one thing all three Nautilus CC models share is CleverClean navigation — an algorithm-driven scanning pattern, not camera-based AI mapping like the pricier Dolphin Sigma uses. That’s worth knowing before you shop by name alone: “CC” tells you the navigation style, not the coverage area or the motor count. Two robots can both be “Nautilus CC” and clean completely different parts of your pool.
Base Nautilus CC — floor only. The cheapest way into the Dolphin brand. It scans and scrubs the pool floor and nothing else — no wall climbing, no waterline scum line removal. It makes sense only if you already have a pressure-side or suction cleaner handling the walls, or you genuinely don’t mind a visible line at the waterline.
Nautilus CC Plus — floor, walls, waterline. The “Plus” is the whole story: it’s the same base hardware with wall-climbing and waterline scrubbing added, which is why it’s Maytronics’ best-seller and our top pick throughout the best Dolphin pool cleaner guide. We cover it in full in our dedicated Nautilus CC Plus review.
Nautilus CC Supreme — CC Plus coverage, faster suction. Same floor-walls-waterline coverage as the Plus, but a third motor pushes suction to 4,500 GPH and it ships with two filter cartridge options instead of one. Independent reviewers weren’t convinced it’s worth the jump — see our full Nautilus CC Supreme review for the complete breakdown, including why Poolbots and Robotic Reviews both steered buyers toward the similarly priced Dolphin Sigma instead.
Which one should you buy?
For the overwhelming majority of inground pools up to 50 ft, the Nautilus CC Plus is the right call. It closes the gap between “floor clean” and “actually clean pool” — the waterline scum line is the thing most owners notice first — without paying for suction most residential pools don’t generate enough debris to need.
Step down to the base Nautilus CC only if another cleaner is already handling your walls and waterline, or budget is the deciding factor and floor-only coverage is genuinely acceptable.
Step up to the CC Supreme only if you have heavier or finer debris load (nearby trees, wind-blown dust, a pool that runs dirtier than average) and you’ve already compared it against the Dolphin Sigma at a similar price — most independent testers rate the Sigma’s gyroscope navigation and quad brushes as the better buy for Supreme-tier money. If your pool and budget are bigger still, the Dolphin Premier adds swappable multi-media filtration on top of everything the Supreme offers.
For the full market beyond Dolphin — Beatbot, Aiper, Polaris, Hayward and more — see our best robotic pool cleaner guide, and if you’re still deciding between a robot and a suction or pressure cleaner, our best automatic pool cleaner guide breaks down all three categories.
The bottom line
“Dolphin Nautilus CC” isn’t one robot — it’s a family of three, and the suffix does all the work. The base CC (about $599) cleans the floor only, the CC Plus (about $749) adds walls and waterline for the price-to-performance sweet spot most owners should buy, and the CC Supreme ($1,149-$1,449) trades a real price jump for faster suction that most residential pools won’t fully use. Start with the CC Plus unless you have a specific reason not to — it’s the model this family is actually known for.
