Dolphin Nautilus Pool Cleaners Compared
The Dolphin Nautilus lineup now spans two distinct branches: established corded AG/CC models and the new cordless EON series for pools up to 50 feet. The best model is not automatically the most expensive one. It depends on your pool size, whether you need wall or waterline coverage, and whether app control is worth paying for.

The Nautilus CC Plus Wi-Fi is the best choice for most inground pools
It combines proven floor and wall cleaning with Wi-Fi scheduling and support for pools up to 50 feet. That makes it the safest all-around recommendation for buyers who want dependable cleaning without moving to a more expensive premium model.
Choose the standard CC Plus if you want to save money and do not care about app control. Choose the Nautilus AG for an above-ground pool. Move up to the CC Pro Wi-Fi when waterline cleaning justifies the extra cost.
New for 2026: the Nautilus EON 100 and EON 120D create a genuine cordless branch inside Nautilus. EON 100 is the more direct cable-free alternative for 50-foot pools, while EON 120D adds sun-ledge cleaning to its waterline-capable cordless platform. Because these are new listings with no Amazon review history returned in our August 20 audit, we are not automatically replacing the proven CC Plus Wi-Fi as the overall winner yet.

Individual Model Reviews
Dolphin Nautilus EON 100
The new mainstream cordless branch: Wi-Fi-connected cleaning for pools up to 50 feet with wall and waterline scrubbing.
Check Current PriceWhy it changes the Nautilus lineup
Until EON, choosing Nautilus meant accepting a cord. EON 100 changes that decision completely: Amazon currently lists it as a cordless, Wi-Fi-connected cleaner for pools up to 50 feet with wall and waterline scrubbing, top-load filtration, and smart navigation.
Pros
- No floating power cable
- Wall and waterline scrubbing
- 50-foot pool positioning
- Wi-Fi connectivity
- Top-load filter
Cons
- New platform with limited long-term ownership evidence
- Battery charging becomes part of the routine
- Amazon audit returned no rating/review count yet
Dolphin Nautilus EON 120D
The premium EON step-up for buyers whose pool geometry includes shallow sun ledges as well as walls and the waterline.
Check Current PriceWhy choose it over EON 100?
The verified Amazon listing explicitly adds sun-ledge cleaning to the cordless, Wi-Fi-connected, waterline-capable EON platform. That is the clearest reason to pay more for 120D rather than treating it as a generic premium upgrade.
Pros
- Cordless design
- Waterline cleaning
- Sun-ledge cleaning
- For pools up to 50 ft
- Wi-Fi + smart navigation
Cons
- Higher purchase price
- Sun-ledge capability may be unnecessary for simpler pools
- New platform without established Amazon review history in our audit
Dolphin Nautilus AG
A straightforward floor cleaner for above-ground pools up to 33 feet.
Check Current PriceWhy we recommend it
The Nautilus AG is the easiest model to recommend for above-ground pool owners who want dependable floor cleaning without paying for features their pool may not need. It includes an active scrubber brush and top-load filter access, making it easier to maintain than basic suction-only cleaners.
Pros
- Designed specifically for above-ground pools
- Active scrubbing brush
- Top-load filter access
- Simple setup
Cons
- No wall cleaning
- No Wi-Fi
- Not intended for larger inground pools
Dolphin Nautilus CC
A useful step up from the AG when your pool needs wall climbing.
Check Current PriceWhy we recommend it
The Nautilus CC fills the gap between a floor-only above-ground cleaner and the larger CC Plus models. It is a better fit for smaller pools where wall climbing matters but Wi-Fi and premium waterline cleaning do not.
Pros
- Wall climbing
- Works in above-ground and small inground pools
- Top-load filter
- Good middle-ground option
Cons
- Limited to pools up to 33 ft
- No Wi-Fi
- No waterline cleaning
Dolphin Nautilus CC Plus
The strongest value for medium inground pools when app control is unnecessary.
Check Current PriceWhy we recommend it
The standard CC Plus remains a strong purchase because it focuses on the features that affect cleaning most: smart navigation, active scrubbing, and wall climbing for inground pools up to 40 feet. It is the model to choose when you would rather save money than pay for remote scheduling.
Pros
- Strong floor and wall cleaning
- Good fit for pools up to 40 ft
- Simple operation
- Better value than Wi-Fi models
Cons
- No smartphone control
- No waterline cleaning
- Smaller pool limit than the Wi-Fi version
Dolphin Nautilus CC Plus Wi-Fi
The best-balanced Nautilus for most residential inground pools.
Check Current PriceWhy we recommend it
The CC Plus Wi-Fi extends the useful pool-length range to 50 feet and adds app control for scheduling. It is not dramatically better at scrubbing than the standard CC Plus, but it is easier to integrate into a regular pool-maintenance routine.
Pros
- Suitable for pools up to 50 ft
- Wi-Fi scheduling
- Wall climbing
- Available with caddy bundles
- Best balance in the lineup
Cons
- Costs more than the standard CC Plus
- No dedicated waterline scrubbing
- Corded design
Dolphin Nautilus CC Pro Wi-Fi
The premium Nautilus choice for wall and waterline cleaning in pools up to 50 feet.
Check Current PriceWhy we recommend it
The CC Pro Wi-Fi earns its premium position by adding waterline scrubbing to the floor-and-wall coverage of the rest of the upper Nautilus range. That upgrade matters most in larger inground pools where grime regularly collects at the waterline.
Pros
- Floor, wall, and waterline cleaning
- Wi-Fi control
- For pools up to 50 ft
- Best cleaning coverage in the Nautilus lineup
Cons
- Higher purchase price
- Smaller value advantage for medium pools
- May be unnecessary if waterline cleaning is not important
Which Dolphin Nautilus Should You Buy?
The Nautilus Line Is Now Corded + Cordless
This is the key 2026 update. EON should not simply be appended as two more rows at the bottom of an old Nautilus chart. It creates a second buying path.
Should You Pay More for Wi-Fi?
Wi-Fi is worth paying for when you use recurring schedules or want to start a cycle without walking to the power supply. It does not automatically improve the robot's scrubbing performance.
The standard CC Plus is the smarter value when you normally place the cleaner in the pool, press start, and remove it after the cycle. The CC Plus Wi-Fi is the better ownership experience when scheduling is part of your weekly routine.
What About the Nautilus Pool-Up?
The Nautilus Pool-Up listing was unavailable when this guide was updated. Because availability is uncertain, we do not recommend building your buying decision around it. The Nautilus AG is the safer current above-ground recommendation, while the Nautilus CC is the better step up when wall climbing matters.

The Nautilus CC Plus Wi-Fi is the best overall model for most buyers because it supports pools up to 50 feet, cleans floors and walls, and adds app scheduling.
Which Nautilus model is best for above-ground pools?
The Nautilus AG is the safest current choice for above-ground pools up to 33 feet. Choose the Nautilus CC when you also want wall climbing.
Is the CC Plus Wi-Fi worth more than the standard CC Plus?
Yes for pools longer than 40 feet or buyers who use app scheduling. Otherwise, the standard CC Plus is the better value.
Which Nautilus cleans the waterline?
The Nautilus CC Pro Wi-Fi is the premium model in this comparison that explicitly adds waterline scrubbing.
Are Dolphin Nautilus cleaners cordless?
Some are now. Nautilus EON 100 and EON 120D are cordless, while the established AG, CC, CC Plus and CC Pro branch remains corded.
What is the difference between Nautilus EON 100 and EON 120D?
Both verified Amazon listings position the robots as cordless, Wi-Fi-connected cleaners for pools up to 50 feet with waterline capability. EON 120D explicitly adds sun-ledge cleaning, making it the more specialized choice for pools with tanning ledges or shallow shelves.
Which model is best for a 50-foot inground pool?
Choose the CC Plus Wi-Fi for the best balance or the CC Pro Wi-Fi when waterline cleaning is worth the premium.
The CC Plus Wi-Fi is the best Nautilus for most buyers
It is the easiest model to recommend because it covers pools up to 50 feet, cleans floors and walls, and adds useful scheduling without forcing every buyer into the highest premium tier.
Choose the standard CC Plus for corded value, the Nautilus AG for above-ground pools, and the CC Pro Wi-Fi when you specifically want proven corded waterline cleaning. Choose EON 100 when cordless convenience is the priority, or EON 120D when sun-ledge cleaning makes the premium worthwhile.
