Main trade-off
Dolphin Nautilus CC
No app or anti-tangle swivel
Head-to-head
Dolphin Nautilus CC vs Nautilus CC Plus Wi-Fi: Plus Wi-Fi reaches a longer pool, neither scrubs the waterline
The short answer
Choose Nautilus CC for a pool up to 33 feet when low lifting weight and simple operation matter. Choose CC Plus Wi-Fi for an in-ground pool up to 40 feet, app control and the listed ultra-fine filter. Neither adds waterline scrubbing, so that requirement calls for a different model.
Before you choose
The reasoning and the trade-offs
The size upgrade is seven feet
A 36-foot pool is outside CC's limit and inside Plus's.
What this is based on
40 − 33 = 7 ft. Published pool length, rather than cable length, sets this boundary.
Main trade-off
Dolphin Nautilus CC Plus with Wi-Fi
About six pounds heavier to retrieve

- Choose it for
- Cover an in-ground pool above 33 and up to 40 feet
- Use MyDolphin Plus and the listed ultra-fine kit

What matters in practice
The differences that matter
The size upgrade is seven feet
A 36-foot pool is outside CC's limit and inside Plus's.
How we reached this conclusion
40 − 33 = 7 ft. Published pool length, rather than cable length, sets this boundary.
The connected model adds six pounds
CC Plus Wi-Fi is roughly 41% heavier dry.
How we reached this conclusion
20.837 − 14.796 = 6.041 lb. 6.041 ÷ 14.796 = 40.8%. Retained water adds to the lifting load.
Wi-Fi does not buy waterline coverage
Both technical tables explicitly exclude waterline scrubbing.
How we reached this conclusion
Each lists floor and wall coverage with Waterline Scrubbing No. An app cannot change that surface limit.

Meaningful differences
What changes the fit
| What changes | Dolphin Nautilus CC | Dolphin Nautilus CC Plus with Wi-Fi | Why it matters |
|---|---|---|---|
| Maximum pool length | 33 ft | 40 ft | Length limits are separate from cable length. |
| Listed pool class | In-ground and above-ground | In-ground | Match installation type before automation. |
| Cleaning coverage | Floor and walls, no waterline | Floor and walls, no waterline | Wall climbing does not establish waterline scrubbing. |
| Connected control | No app | MyDolphin Plus and weekly timer | Plus adds remote scheduling. |
| Included filter type | Fine filter kit | Ultra-fine filter kit | Confirm supplied panels in the exact listing. |
| Dry weight and swivel | 14.796 lb, no swivel | 20.837 lb, swivel | A swivel does not remove cable-care requirements. |
What you give up
Every choice has a cost
If you choose Dolphin Nautilus CC
- Fine filter rather than the Plus's ultra-fine kit
If you choose Dolphin Nautilus CC Plus with Wi-Fi
- Still no waterline scrubbing
Recommendation switch
The decision flips if...
The pool is longer than 33 and no longer than 40 feet
Choose Dolphin Nautilus CC Plus with Wi-Fi. Only Plus meets the published length range.
Waterline scrubbing is required
Choose neither. Both lack that function.
A sub-18 lb dry robot is essential
Choose Dolphin Nautilus CC. Only CC meets that weight threshold.
What matters in practice
How to make the call
Rule out an undersized cleaner
CC is a smaller-pool machine. Plus is justified above 33 feet, provided the pool remains within its 40-foot in-ground rating. Neither cable length nor filter size overrides that limit.
Separate controls from cleaning surfaces
The app and timer can simplify when a run starts. They do not add waterline scrubbing, which both technical tables exclude. Buyers wanting that task need a model explicitly listing it.
Plan retrieval and filter care
CC is considerably lighter dry. Plus offers a swivel and ultra-fine media, but still needs cable care and filter cleaning. Confirm the supplied filter parts instead of assuming every Nautilus bundle is identical.
What this comparison cannot tell you
- No cleaning-speed, pickup or reliability test was performed. Dry weight excludes retained water.
