Quick Answer: The Dolphin Nautilus CC Supreme (~$1,149 sale / $1,449 list, per Maytronics) is Maytronics’ mid-premium robotic cleaner — a Wi-Fi-connected, three-motor upgrade over the Nautilus CC Plus with 4,500 GPH suction and two included filter options (Fine and Ultra-Fine cartridges). It cleans inground pools up to 50 ft with 1.5 or 2.5-hour cycle settings. Independent testers are lukewarm: Robotic Reviews scored it 83/100 but flagged its filter system as a weak spot, and Poolbots called it overpriced next to the similarly priced Dolphin Sigma and Premier. For most inground pools the cheaper CC Plus remains the smarter buy — the Supreme only earns its keep if you specifically want its faster suction and can’t stretch to the Sigma.
The Nautilus CC Supreme sits in an awkward spot in Maytronics’ lineup: pricier than the brand’s best-seller CC Plus, but without the gyroscope navigation of the Sigma or the swappable multi-media filtration of the Premier that would clearly justify the jump. Here’s what it actually gets you, where independent testers landed, and who should — and shouldn’t — buy it.

Dolphin Nautilus CC Supreme
- Three commercial-grade motors deliver 4,500 GPH suction — faster than the CC Plus.
- Two filter cartridges included: standard Fine and Ultra-Fine, both top-loading.
- Wi-Fi + MyDolphin Plus app for remote start, scheduling and status checks.
- Selectable 1.5 or 2.5-hour cycles to match how dirty the pool actually is.
Waiting on freight shipping for a 24-lb robot is its own kind of annoying — a free 30-day Amazon Prime trial can get it to your door by the weekend instead, and you can cancel anytime before the trial ends if you don’t plan to keep it.
By the numbers
- Suction rate: Maytronics’ own spec sheet and independent testing at Robotic Reviews both confirm 4,500 GPH across three motors — noticeably stronger than the single-motor CC Plus, though it lands below the Sigma’s dual-motor system on large debris.
- Independent score: Robotic Reviews gave the CC Supreme an 83 out of 100 overall — solid on waterline cleaning and warranty perception, but its filtration was rated “Bad” specifically because it ships without the NanoFilters some rival Dolphins include standard.
- Price drift: Maytronics’ own US store lists it at $1,149 sale (down from $1,449 list), while multiple third-party listings put it as high as $1,499–$1,500 — a real spread worth checking before buying from a reseller.
- Weight: At ~24.6 lbs (per Maytronics’ own dimensions listing), it’s heavy enough that most owners will want the optional caddy for lifting it out of the pool, the same trade-off flagged in Poolbots’ independent test.
What it does well
Real suction upgrade over the CC Plus. Three motors and 4,500 GPH give the CC Supreme genuinely stronger pickup than Maytronics’ entry-level corded robots — on pools with fine silt or heavier debris loads, that extra suction shows up in cleaner filters and fewer missed passes.
Two filter options in the box. Unlike the base CC Plus, the Supreme ships with both a standard Fine cartridge and an Ultra-Fine cartridge, so you can switch between everyday debris and fine pollen/algae without buying a separate filter kit — a genuine convenience win, even if Robotic Reviews still dinged it for lacking the four-option lineup some competitors offer.
Selectable cycle length. The 1.5-hour and 2.5-hour cycle options let you match cleaning time to how dirty the pool actually is that week, instead of running one fixed cycle regardless of debris load — useful after a storm versus routine maintenance.
Wi-Fi app control. MyDolphin Plus adds remote start, scheduling, and status checks — the same connectivity tier as the current CC Plus, layered on top of the Supreme’s stronger hardware.
Where it falls short
- Hard to justify against the Sigma. At a similar price, the Dolphin Sigma adds gyroscope-based SmartNav mapping and quad brushes — both Poolbots and Robotic Reviews independently concluded the Sigma is the smarter buy for the same money.
- Weak filtration versus its price. Robotic Reviews explicitly rated the filter system “Bad” because it comes without NanoFilters, a feature some rivals in this price bracket include.
- Shorter warranty than the Premier. Maytronics’ own page lists just 1 year on the CC Supreme, versus the Dolphin Premier’s 3-year non-prorated coverage at a comparable list price — a meaningful gap if long-term support matters to you.
- No gyroscope navigation. Despite the premium price, it still scans with the same CleverClean pattern as the budget CC Plus rather than mapping the pool like the Sigma does.
Dolphin Nautilus CC Supreme vs the alternatives
| Model | Navigation | Filtration | Warranty | Price |
|---|---|---|---|---|
| Nautilus CC Supreme | CleverClean scanning | Fine + Ultra-Fine (2 options) | 1 year | $1,149–$1,449 |
| Nautilus CC Plus | CleverClean scanning | Fine + Ultra-Fine baskets | 1 year (US) | ~$799 |
| Dolphin Sigma | Gyroscope SmartNav 3.0 | Oversized dual cartridges | — | ~$1,499 |
| Dolphin Premier | CleverClean scanning | Multi-media (leaf bag + 2 cartridges) | 3 years | $1,999–$2,499 |
The comparison that matters most: at roughly the same price as the Sigma, the CC Supreme brings weaker navigation and a plainer filter lineup — which is exactly why independent reviewers steer buyers toward the Sigma instead. And against the cheaper CC Plus, the Supreme’s extra suction rarely justifies a $350–650 premium on a typical residential pool.

Who should buy the Nautilus CC Supreme
Buy it if you specifically want more suction than the CC Plus but don’t want to spend Sigma or Premier money, and you’re comfortable with CleverClean’s proven-but-unmapped scanning pattern. It’s a reasonable middle-tier pick for pools with moderate-to-heavy debris that don’t need gyroscope navigation or swappable multi-media filtration.
Look elsewhere if you want the smartest navigation Dolphin makes (Sigma), the best filtration flexibility for a leaf-heavy pool (Premier), or simply the best value for a standard inground pool (CC Plus, our top pick site-wide). For the full picture, our best robotic pool cleaner guide ranks every tier of the market including brands beyond Dolphin.
The bottom line
The Dolphin Nautilus CC Supreme ($1,149 sale / $1,449 list) is a competent mid-premium robot — stronger suction and two included filter options beat the entry-level CC Plus on paper. But independent testers at Robotic Reviews (83/100, filtration rated “Bad”) and Poolbots (called it overpriced) both landed on the same conclusion: at this price, the Dolphin Sigma or Dolphin Premier deliver more for similar money. We rate it ★★★☆ — a solid robot, just not the smartest way to spend Supreme-tier dollars.
