The catch
Dolphin Nautilus CC
Neither app nor anti-tangle swivel
Side by side
Dolphin Nautilus CC vs Nautilus CC Plus Wi-Fi Compared: Neither scrubs the waterline, but Plus Wi-Fi reaches a longer pool
Quick verdict
When a pool of up to 33 feet, low lifting weight and simple operation are what matter, Nautilus CC is the one to pick. CC Plus Wi-Fi is for an in-ground pool of up to 40 feet, app control and the listed ultra-fine filter. Waterline scrubbing is missing from both, so if you need it, look at a different model.
Before you buy
Why, and what it costs you
Moving up in size adds seven feet
CC's limit does not reach a 36-foot pool, but Plus's does.
Where this comes from
This boundary is set by published pool length and not by cable length. 40 − 33 = 7 ft.
The catch
Dolphin Nautilus CC Plus with Wi-Fi
Retrieval means lifting about six pounds more
Dolphin Nautilus CC
- Why pick it
- Pull out a robot of roughly 14.8 lb after every run
- Take care of a suitable small pool and skip app setup
- The catch
- Neither app nor anti-tangle swivel
Dolphin Nautilus CC Plus with Wi-Fi
- Why pick it
- Serve an in-ground pool over 33 and up to 40 feet
- Run MyDolphin Plus along with the listed ultra-fine kit
- The catch
- Retrieval means lifting about six pounds more

In practice
Differences you will notice
Moving up in size adds seven feet
CC's limit does not reach a 36-foot pool, but Plus's does.
How we worked this out
This boundary is set by published pool length and not by cable length. 40 − 33 = 7 ft.
Six pounds more come with the connected model
Dry, CC Plus Wi-Fi weighs roughly 41% more.
How we worked this out
Retained water adds to the lifting load. 20.837 − 14.796 = 6.041 lb, and 6.041 ÷ 14.796 = 40.8%.
Waterline coverage does not come with Wi-Fi
Waterline scrubbing is explicitly excluded in both technical tables.
How we worked this out
Floor and wall coverage is listed for each, with Waterline Scrubbing No. No app can change that surface limit.

Spec by spec
Where they really differ
| Spec | Dolphin Nautilus CC | Dolphin Nautilus CC Plus with Wi-Fi | In practice |
|---|---|---|---|
| Maximum pool length | 33 ft | 40 ft | Cable length is not the same thing as a length limit. |
| Listed pool class | In-ground and above-ground | In-ground | Decide the installation type, then automation. |
| Cleaning coverage | Floor and walls, no waterline | Floor and walls, no waterline | Climbing walls does not show that a robot scrubs the waterline. |
| Connected control | No app | MyDolphin Plus and weekly timer | Remote scheduling is what Plus adds. |
| Included filter type | Fine filter kit | Ultra-fine filter kit | Check which panels are supplied in the exact listing. |
| Dry weight and swivel | 14.796 lb, no swivel | 20.837 lb, swivel | Cable care is still needed even with a swivel. |
Trade-offs
What each pick costs you
With Dolphin Nautilus CC
- A fine filter, while Plus has the ultra-fine kit
With Dolphin Nautilus CC Plus with Wi-Fi
- Waterline scrubbing is still absent
Change of plan
When the answer changes
Pool length falls above 33 and up to 40 feet
Go with Dolphin Nautilus CC Plus with Wi-Fi. The published length range is met by Plus alone.
Waterline scrubbing has to be included
Neither model fits. Neither has that function.
Dry weight below 18 lb is essential
Go with Dolphin Nautilus CC. That weight threshold is met by CC alone.
Decision guide
How to decide
Pick Nautilus CC for a pool up to 33 feet if you value low lifting weight and simple operation. Pick 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 need points to a different model.
Eliminate a cleaner that is too small
The CC is a smaller-pool machine. The Plus makes sense once a pool is longer than 33 feet, as long as it stays within the 40-foot in-ground rating. That limit holds no matter the cable length or filter size.
Keep controls apart from cleaning surfaces
An app and a timer can make it easier to decide when a run starts. Neither adds waterline scrubbing, which both technical tables rule out. If you want that task done, you need a model that lists it explicitly.
Prepare for retrieval and filter care
Dry, the CC is considerably lighter. The Plus brings a swivel and ultra-fine media, yet it still needs cable care and filter cleaning. Check which filter parts are supplied rather than assuming every Nautilus bundle is the same.
What this page can’t tell you
- No cleaning-speed, pickup or reliability test was run. Dry weight leaves out any retained water.
