In practice
Differences you will notice
Dry, Supreme weighs about 66 percent more
That works out to 9.834 pounds.
How we worked this out
Subtract 14.796 from 24.63 for 9.834, then divide by 14.796 for 66.5 percent.
Short and long cycles fall 30 minutes either side of CC
Against the CC default, Supreme can run shorter or longer by half an hour.
How we worked this out
Two hours is 120 minutes. Supreme's 90 and 150 minutes differ by plus or minus 30. The scope of each cycle varies.
Three different control and coverage features come with Supreme
The difference spans waterline work, app access and recurring scheduling.
How we worked this out
Supreme lists all three. The exact CC page lists none of them: waterline, mobile application and weekly timer.
Option A
Dolphin, 99996113-USB
Nautilus CC
This compact corded Dolphin climbs walls and still stays light and uncomplicated.
- Best for
- A small in-ground pool where you want the floor and walls cleaned by a robot that is easy to lift
Facts we checked
- For pools up to 33 feet, Maytronics rates the exact model 99996113-USB.
- A two-hour cycle takes in the floor and walls.
- Per the current tech specs: one brush, no weekly timer and a 14.796-pound dry weight.
Option B
Dolphin, 99991083-PC
Nautilus CC Supreme
The flagship Nautilus has three brushes, reaches the waterline and runs short or deep cycles you control from the app.
- Best for
- An in-ground 50-foot pool that needs full-line scrubbing and finer filtration
Facts we checked
- In pools up to 50 feet, it covers the floor, walls and waterline.
- Pick a 1.5 or 2.5 hour cycle.
- Documented features are three brushes, 4,500 GPH flow, app control and an extra ultra-fine filter kit.

| Dry weight | 14.796 pounds | 24.63 pounds | Supreme is almost ten pounds heavier before water. |
| Cycles | Two hours | 1.5 or 2.5 hours | Supreme has both a short and a longer cycle choice. |

| Filter and brushes | Fine filter, one brush | Fine plus extra ultra-fine kit, three brushes | Filter choice and brush hardware are added on Supreme. |
Trade-offs
What each pick costs you
With Dolphin Nautilus CC
- No app, weekly timer or automation mode appears in the listing for the exact current US model.
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 waterline coverage, less weight and no need for an app
Neither model fits. Full-zone cleaning comes at about 18.5 pounds with Advantage Ultra.
Decision guide
How to decide
Pick CC for a lighter, simpler floor-and-wall cleaner. Pick Supreme for waterline coverage, app scheduling and finer filter options, and accept nearly ten pounds more dry weight.
If you lift the robot every day
A dry-weight gap of nearly ten pounds deserves serious thought. Premium cleaning features pay off only when you can retrieve the robot comfortably and maintain it consistently. With the Supreme, you need a sensible storage and lifting routine, especially when it is wet.
If the pool is bigger or dirtier
The Supreme's higher pool-length rating, waterline coverage and extra filter kit each address a different part of the job. Having three brushes does not mean three times the cleaning. Decide by looking at which zones and which debris the smaller CC would leave you to handle by hand.
On remote scheduling
Through the powered system, the Supreme's app can schedule and control cycles. The CC is simpler and has no documented timer. Connected control still calls for a safe power-supply position and regular filter cleaning, so the cleaner does not become a maintenance-free installation.
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”, “Regular scrubbing is needed at the waterline”, “I want an app for controls and status”, and “My pool collects fine dust, sand or dead algae”, 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”, “Regular scrubbing is needed at the waterline”, “I want an app for controls and status”, and “My pool collects fine dust, sand or dead algae”. A need with no documented match is not counted.
