What matters in practice
The differences that matter
The weight advantage is modest
C2 is about 0.9 pound lighter dry.
How we reached this conclusion
18.478 minus 17.6 equals 0.878 pound, about 4.8 percent of Ultra weight.
A full C2 run and recharge can occupy six hours
Its maximum run and listed charge are each about three hours.
How we reached this conclusion
180 minutes runtime plus 180 minutes charging equals 360 minutes. This is a scheduling illustration, not a promised duty cycle.
Both already include the waterline in their named scope
The power and maintenance routine is more decisive than zone names.
How we reached this conclusion
Both document floor, wall and waterline cleaning. Compare cable handling, recharging, app controls and filter care.

Meaningful differences
What changes the fit
| What changes | WYBOT C2 | Dolphin Advantage Ultra | Why it matters |
|---|---|---|---|
| Power | Cordless battery | Corded power supply | C2 removes the cable while Ultra avoids battery recharge waits. |
| Session timing | Up to 180 minutes, about three-hour charging | Two-hour default cycle | Maximum battery runtime and preset cycle duration are different measures. |
| Filter | 180-micron plus 10-micron secondary media | Fine filter kit without a matched micron figure here | C2 has a quantified finer stage, but no exact capture ranking is established. |
| Control | App and seven modes | No app, weekly timer | C2 provides phone-selected modes. |
| Dry weight | 17.6 pounds | 18.478 pounds | The published dry-weight gap is under one pound. |
What you give up
Every choice has a cost
If you choose WYBOT C2
- Battery charging adds downtime between long cycles.
If you choose Dolphin Advantage Ultra
- The standard two-hour cycle offers less tuning than the Supreme.
Recommendation switch
The decision flips if...
You want corded operation and app control together
Choose neither. Advantage Pro adds MyDolphin Plus to a full-zone corded platform.
What matters in practice
How to make the call
For frequent cleanup after storms
A corded cleaner can begin another supported cycle without waiting for its battery to refill. You still need to empty and rinse the filter, remove large debris manually where required and follow operating limits. C2 is more convenient when one charged session usually handles the routine.
For a crowded pool deck
C2 removes the in-water cleaning cable, but charging and storage still need a suitable dry location. Ultra power supply needs safe placement and cable management. Choose the setup that can be deployed consistently without creating a troublesome path around the pool.
For very fine material
C2 supplies a 10-micron secondary layer. Ultra fine-filter name alone is not a matched micron specification, so this page avoids inventing a capture ratio. Confirm the exact included filter and available replacements for the offer you are considering.
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.

None of the 27 models checked covers every part of “I do not want a cable across the pool”, “I prefer corded power without a battery deadline”, “I want controls and status in an app”, and “Fine dust, sand or dead algae settles in my pool”, so the recommendation favors the closest practical compromise.
