What matters in practice
The differences that matter
Supreme adds one-third more dry weight
The gap is 6.152 pounds.
How we reached this conclusion
24.63 minus 18.478 equals 6.152. Divide by 18.478 for 33.3 percent.
The flow specification rises only 12.5 percent
The difference is 500 GPH.
How we reached this conclusion
4500 minus 4000 equals 500. Divide by 4000 for 12.5 percent. No cleaning-speed ratio is inferred.
Both already cover the same named zones and pool length
The upgrade buys control and hardware rather than a higher length limit.
How we reached this conclusion
Both list 50 feet plus floor, walls and waterline. Differences are weight, cycles, app, brushes and filter contents.

Meaningful differences
What changes the fit
| What changes | Dolphin Advantage Ultra | Dolphin Nautilus CC Supreme | Why it matters |
|---|---|---|---|
| Dry weight | 18.478 pounds | 24.63 pounds | Supreme adds about 6.2 pounds. |
| Cycle choices | Two-hour default | 1.5 and 2.5 hours | Supreme provides shorter and longer options. |
| App | None | MyDolphin Plus | Supreme adds remote cycle control. |
| Brushes | Two | Three | Supreme adds a third brush, not a measured cleaning multiplier. |
| Flow and filter | 4,000 GPH, fine filter | 4,500 GPH, fine plus extra ultra-fine kit | Supreme has a higher published flow and another filter option. |
What you give up
Every choice has a cost
If you choose Dolphin Advantage Ultra
- The standard two-hour cycle offers less tuning than the Supreme.
If you choose Dolphin Nautilus CC Supreme
- The cable and power supply still need a safe deck position.
Recommendation switch
The decision flips if...
You want app control on the Advantage platform
Choose neither. Advantage Pro combines connected controls with floor, wall and waterline coverage.
What matters in practice
How to make the call
For a standard 50-foot-or-smaller pool
Ultra already supplies the full set of named cleaning zones. Supreme should therefore earn its place through the features you will use, such as app scheduling or finer filtration. A more expensive model is not automatically necessary merely because the pool has a waterline.
For filter changes through the season
Supreme extra ultra-fine kit provides another media choice for finer material. That can be useful after dusty weather, while coarser debris may be easier to manage with the standard kit. Follow the supplied instructions for installing and rinsing each set.
For carrying and storage
Ultra saves a little over six pounds dry. Supreme added weight is noticeable when lifted over the pool edge or carried to storage. Compare the route and retrieval posture along with the app features, especially if the same person handles the robot after every session.
What this comparison cannot tell you
- Manufacturer flow, runtime and coverage figures are not matched independent pool-cleaning tests.
- Wall climbing, steps and waterline performance depend on pool geometry and surface conditions. App support does not establish live underwater radio control.
What the facts say
What the comparison shows
Useful conclusions from the current robot pool cleaners comparison, followed by the checked facts used to reach them.
Compared set
None of the 27 models checked covers every part of “I need a lighter robot for the poolside lift”, “Fine dust, sand or dead algae settles in my pool”, “I want controls and status in an app”, and “The waterline needs regular scrubbing”, so the recommendation favors the closest practical compromise.
