Head-to-head
Dolphin Nautilus CC vs WYBOT B1: B1 adds cordless waterline work, its area label is not a length limit
The short answer
Choose WYBOT B1 when waterline routes and cable-free operation are required. Choose Nautilus CC for a permitted pool within its 33-foot length limit when its corded floor-and-wall cycle fits the routine. B1's area headline is not a substitute for checking all pool dimensions, and neither runtime figure proves better cleaning.
Before you choose
The reasoning and the trade-offs
A waterline job requires a different route
Nautilus CC covers the floor and walls but does not claim waterline cleaning. WYBOT B1 offers waterline routes, making it the relevant candidate when that band is a routine manual job you want the robot to address. Dolphin remains useful for a floor-and-wall owner who accepts separate waterline maintenance and prefers corded power. B1's 120-minute maximum battery runtime and Dolphin's two-hour program do not establish equal cleaning coverage or equal performance.
What this is based on
Both figures equal 120 minutes numerically, but one is a maximum endurance claim and the other a programmed cycle. Coverage and route design are separate specifications.

About this comparison
Compare Dolphin Nautilus CC and WYBOT B1 for waterline routes, pool dimensions, corded use, recharging and the limits of runtime claims.
Decide whether waterline scrubbing is required, then verify pool dimensions without treating area and length limits as interchangeable.
Winner by situation
Start with what you need it to do
Waterline scrubbing is essential
CC covers floor and walls. B1 lists waterline routes.
- Dolphin Nautilus CC
- Not suitable
- WYBOT B1
- Good
My pool is 38 feet long
CC is rated to 33 feet. B1's area headline alone does not verify all pool dimensions.
- Dolphin Nautilus CC
- Not suitable
- WYBOT B1
- Depends
I want no in-pool power cable
CC is corded and B1 is rechargeable and cordless.

I need a verified weekly timer on this exact model
CC's technical table says no timer. A qualifying B1 weekly schedule was not established in this evidence.

What matters in practice
The differences that matter
A waterline job requires a different route
Nautilus CC covers the floor and walls but does not claim waterline cleaning. WYBOT B1 offers waterline routes, making it the relevant candidate when that band is a routine manual job you want the robot to address. Dolphin remains useful for a floor-and-wall owner who accepts separate waterline maintenance and prefers corded power. B1's 120-minute maximum battery runtime and Dolphin's two-hour program do not establish equal cleaning coverage or equal performance.
How we reached this conclusion
Both figures equal 120 minutes numerically, but one is a maximum endurance claim and the other a programmed cycle. Coverage and route design are separate specifications.
Pool area does not cancel a length limit
A 38-by-12-foot rectangle has only 456 square feet of surface area, yet its 38-foot length exceeds Nautilus CC's 33-foot rating. Dolphin is therefore outside its published length limit for that example. B1's 1,150-square-foot headline makes it worth investigating, but does not by itself verify every dimension, depth or wall shape. Choose the robot only after its complete pool requirements match. For a shorter suitable pool, the corded versus rechargeable workflow can decide.
How we reached this conclusion
38 multiplied by 12 is 456 square feet. A surface-area total and a maximum pool length constrain different aspects of a route and should remain separately labeled.
Fine debris needs a filter check separate from coverage
If the recurring problem is very fine settled powder, B1's 180-micron filter specification is more useful than its wall-climbing claim, but it does not establish complete retention of smaller particles. This packet does not establish a comparable numerical filter rating for Nautilus CC. Before choosing either for that job, confirm the exact supplied media and supported alternatives with the maker. A floor-and-wall route cannot make unsuitable filter media retain the target debris.
How we reached this conclusion
B1 lists 180-micron media. CC's reviewed coverage facts do not provide a matching numerical filtration rating. No fine-silt retention test was found.
Choice A
Dolphin, 99996113-USB
Nautilus CC
A compact corded Dolphin that adds wall climbing without becoming heavy or complicated.

- Duration: The standard cycle lasts two hours.
- Power source: It is corded.
Choice B
WYBOT, 2026
B1
A compact cordless step-up that adds wall and waterline modes plus app setup.
- Best matched use
- Add documented waterline routes
Checked facts
- Pool-size basis: The published pool-area limit is 1,150 square feet.
- Coverage: Selectable cleaning includes floor, wall and waterline routes.
- Duration: Maximum battery runtime is 120 minutes.
- Power source: The cleaner is cordless and requires recharging.
Meaningful differences
What changes the fit
| What changes | Dolphin Nautilus CC | WYBOT B1 | Why it matters |
|---|---|---|---|
| Pool-size basis | The current technical limit is pools up to 33 feet. | The published pool-area limit is 1,150 square feet. | Maximum length and surface area must remain separately labeled. |
| Coverage | It cleans the floor and walls without a waterline-cleaning claim. | Selectable cleaning includes floor, wall and waterline routes. | Only B1 lists waterline routes. |
| Duration | The standard cycle lasts two hours. | Maximum battery runtime is 120 minutes. | Fixed cycle length is not directly equivalent to maximum battery runtime. |
| Power source | It is corded. | The cleaner is cordless and requires recharging. | Corded placement and battery charging create different owner work. |
What you give up
Every choice has a cost
If you choose Dolphin Nautilus CC
- The 33-foot maximum excludes the 38-foot example
If you choose WYBOT B1
- A 180-micron filter is not a promise of capturing every fine particle
Recommendation switch
The decision flips if...
Use a corded floor-and-wall cycle
Choose Dolphin Nautilus CC. Choose a documented two-hour program for a permitted pool. No documented waterline cleaning.
Add documented waterline routes
Choose WYBOT B1. Remove the in-pool power cable. The area headline does not establish every dimensional limit.
What matters in practice
Before you choose
What this comparison cannot tell you
- The rectangle is a sizing example, not confirmation of B1 compatibility.
