| What changes | Dolphin Nautilus CC | Dolphin Nautilus CC Supreme | Why it matters |
|---|---|---|---|
| Coverage and pool limit | Floor and walls, 33 feet | Floor, walls and waterline, 50 feet | Supreme reaches a larger documented pool class and another cleaning zone. |
| Dry weight | 14.796 pounds | 24.63 pounds | Supreme adds almost ten pounds before water. |
| Cycles | Two hours | 1.5 or 2.5 hours | Supreme offers short and longer cycle choices. |
| Control | No app or weekly timer | MyDolphin Plus and weekly timer | Supreme supports connected scheduling. |
| Filter and brushes | Fine filter, one brush | Fine plus extra ultra-fine kit, three brushes | Supreme adds filter choice and brush hardware. |
What you give up
Every choice has a cost
If you choose Dolphin Nautilus CC
- The exact current US model lists no app, weekly timer or automation mode.
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 waterline coverage with less weight and no app requirement
Choose neither. Advantage Ultra weighs about 18.5 pounds and provides full-zone cleaning.
What matters in practice
How to make the call
For someone who lifts the robot daily
The nearly ten-pound dry difference deserves serious consideration. Premium cleaning features help only if the robot can be retrieved comfortably and maintained consistently. Supreme needs a sensible storage and lifting routine, especially when wet.
For a larger or dirtier pool
Supreme higher pool-length rating, waterline coverage and extra filter kit address different parts of the job. Three brushes alone do not establish three times the cleaning. Choose based on the zones and debris that the smaller CC leaves for manual work.
For remote scheduling
Supreme app can schedule and control cycles through the powered system. CC is simpler and lacks that documented timer. Connected control still requires safe power-supply placement and regular filter cleaning, so it does not turn the cleaner into a maintenance-free installation.
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.
