How we worked this out
Subtract 18.478 from 24.63 for 6.152, then divide by 18.478 for 33.3 percent.
Only 12.5 percent more flow is specified
They differ by 500 GPH.
How we worked this out
Take 4000 from 4500 for 500, then divide by 4000 for 12.5 percent. Nothing here is meant to infer a cleaning-speed ratio.
Named zones and pool length are already the same on both
Paying for the upgrade gets control and hardware. The length limit stays the same.
How we worked this out
Each lists 50 feet along with floor, walls and waterline. They differ in weight, cycles, app, brushes and filter contents.

Trade-offs
What each pick costs you
With Dolphin Advantage Ultra
- Compared with the Supreme, the standard two-hour cycle gives you less to adjust.
With Dolphin Nautilus CC Supreme
- You still need a safe deck spot for the cable and power supply.
Change of plan
When the answer changes
You want to run the Advantage platform from an app
Neither model fits. Advantage Pro covers floor, walls and waterline and adds connected controls.
Decision guide
How to decide
Pick Ultra for full-zone cleaning in a lighter body with no app setup. Pick Supreme for app control, selectable cycles and an extra ultra-fine filter kit.
A standard pool that is 50-foot-or-smaller
The Ultra already covers every named cleaning zone, so the Supreme has to earn its place through features you will use, such as app scheduling or finer filtration. Having a waterline in the pool does not by itself make the more expensive model necessary.
As filter needs shift through the season
The extra ultra-fine kit with the Supreme gives you another media option for finer material. It can come in handy after dusty weather, whereas coarser debris may be easier to handle with the standard kit. Install and rinse each set as the supplied instructions say.
On carrying and storage
The Ultra weighs a little over six pounds less when dry. The Supreme's extra weight shows when you lift it over the pool edge or carry it to storage. Weigh the route and the retrieval posture alongside the app features, particularly if the same person handles the robot after every session.
What this page can’t tell you
- The flow, runtime and coverage figures come from the manufacturer and are not matched, independent pool-cleaning tests.
- How well a robot climbs walls, handles steps and cleans the waterline depends on pool geometry and surface conditions. Having an app does not mean you get live underwater radio control.
By the numbers
What the data shows
What we found across the robot pool cleaners we compare, plus the checked facts behind each finding.
How many fit
None of the 27 models checked meets all of “I need a robot light enough for the lift at poolside”, “My pool collects fine dust, sand or dead algae”, “I want an app for controls and status”, and “Regular scrubbing is needed at the waterline”, so the pick goes to the closest practical compromise.
0 models fit, out of 27 checkedShow the facts and the math
How we countedThe count uses each product's current fit ratings for “I need a robot light enough for the lift at poolside”, “My pool collects fine dust, sand or dead algae”, “I want an app for controls and status”, and “Regular scrubbing is needed at the waterline”. A need with no documented match is not counted.
