Quick Answer: “Nautilus CC” is Maytronics’ family name for its CleverClean-navigation robotic pool cleaners, and it actually covers four tiers: the base Nautilus CC ($649 sale / $699 list, floor and walls — not floor-only, per Maytronics’ own current spec page), the Nautilus CC Plus (about $749, adds waterline scrubbing and Wi-Fi, Maytronics’ best-seller), the Nautilus CC Pro ($999 sale / $1,149 list, a rarely-mentioned two-motor step up most guides skip), and the Nautilus CC Supreme ($1,149 sale / $1,449 list, three motors and the family’s strongest suction). For most inground pools up to 50 ft, the CC Plus is the one to buy — per Maytronics’ own current pages, all three paid tiers now carry the same 1-year warranty, so the pricier options buy hardware, not extra coverage or protection.
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,” “Pro,” 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.
Last updated: October 5, 2026 — corrected the base Nautilus CC's coverage: Maytronics' own current spec page (and an independent Poolbots test) confirm it cleans floor and walls, not floor-only as this guide previously described it, and that it has no weekly timer either (power-supply control only). Fixed the base CC's price to its current $649 sale / $699 list. See our new dedicated Nautilus CC review for the full breakdown.
Last updated: October 3, 2026 — added the Nautilus CC Pro, a real currently-sold fourth tier that this guide had missed entirely (it's absent from Maytronics' own "CC vs CC Plus vs CC Supreme" marketing and most third-party buying guides), and corrected the warranty picture across the family: Maytronics cut the Nautilus CC line's warranty to a flat 1 year in 2026 (down from 2-2.5 years), confirmed directly on Maytronics' own US product pages for the CC Plus, CC Pro, and CC Supreme.
The Nautilus CC family at a glance
| Model | Cleans | Motors | Wi-Fi | Warranty | Price |
|---|---|---|---|---|---|
| Nautilus CC (base) | Floor and walls | 1 | No app or timer | — | $649 sale / $699 list |
| Nautilus CC Plus | Floor, walls, waterline | 1 | Yes (current model) | 1 year | ~$749 |
| Nautilus CC Pro | Floor, walls, waterline | 2 | Yes | 1 year | $999 sale / $1,149 list |
| Nautilus CC Supreme | Floor, walls, waterline | 3 | Yes | 1 year | $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 four 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. The CC Pro’s two motors land in between, at roughly 4,000-4,500 GPH depending on the source.
- Warranty is flat across every paid tier: Per Maytronics’ own current product pages, the CC Plus, CC Pro, and CC Supreme all carry the same 1-year warranty — down from the 2-2.5 years these models carried previously. Spending more within this family buys motors and filtration, not longer coverage.
- 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. The CC Pro has no independent lab test found yet, since most reviewers skip straight from the CC Plus to the CC Supreme.
- Coverage: All four 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 Pro — the tier most guides forget. Same floor-walls-waterline coverage as the Plus, with a second motor and brush added and a reusable dual-layer mesh filter in place of swappable cartridges. It’s a real, currently-sold SKU (Maytronics model 99996207-PCI) — it’s just absent from most buying guides, including Maytronics’ own marketing, which tends to jump straight from the Plus to the Supreme. Full breakdown in our dedicated Nautilus CC Pro 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 if budget is the deciding factor — it still climbs the walls, it just skips the waterline scrub and Wi-Fi.
Consider the CC Pro only if you want a second motor’s worth of extra suction over the CC Plus but don’t want to spend CC Supreme money — just know it doesn’t carry a longer warranty for the extra ~$250, since Maytronics backs every paid Nautilus CC tier with the same 1 year today.
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.
Nautilus CC isn’t the only Dolphin family with a confusing suffix lineup — Maytronics runs the same base/PRO/ULTRA pattern on its separate Dolphin Advantage line. See our Dolphin Advantage explained guide if you’ve been comparing the two families and aren’t sure which naming scheme you’re looking at.
The bottom line
“Dolphin Nautilus CC” isn’t one robot — it’s a family of four, and the suffix does all the work. The base CC ($649-$699) cleans the floor and walls — not floor-only — the CC Plus (about $749) adds the waterline scrub and Wi-Fi for the price-to-performance sweet spot most owners should buy, the CC Pro ($999 sale / $1,149 list) is a real but rarely-discussed two-motor step up, and the CC Supreme ($1,149-$1,449) trades a real price jump for faster suction that most residential pools won’t fully use. None of the paid tiers currently buy you a longer warranty than the CC Plus — Maytronics backs all three at a flat 1 year. Start with the CC Plus unless you have a specific reason not to — it’s the model this family is actually known for.
