The catch
Dolphin Nautilus AG
Walls and waterline are left as separate work by floor-only coverage
Side by side
Dolphin Nautilus AG vs WYBOT B1 Compared: B1 takes in walls and waterline, while AG covers a powered floor-only job
Quick verdict
Nautilus AG is the choice for a powered floor-only routine in a compatible above-ground pool up to 30 feet. WYBOT B1 is the choice when documented wall and waterline routes matter and charging is manageable. You cannot turn the B1's 1,150-square-foot area label into a universal pool-length approval, and its two-hour maximum is not a measured cleaning advantage.
Before you buy
Why, and what it costs you
Checking round-pool area does not remove a length limit
About 804 square feet is the surface area of a round pool 32 feet across. That sits below B1's 1,150-square-foot headline but beyond Nautilus AG's 30-foot length limit, so rule out AG at that size. B1 stays conditional, because surface area alone does not verify its shape, depth, material or above-ground installation requirements. In a compatible smaller pool, coverage and charging are the clearer deciding factors.
Where this comes from
16 squared times pi comes to about 804 square feet. In this example, the diameter is the relevant maximum span. No maximum pool length for B1 is invented from its area label.

What this page compares
Dolphin Nautilus AG and WYBOT B1 are compared on above-ground pool sizing, wall and waterline tasks, charging and cleaning-duration claims.
Which one fits
Pick the situations that sound like you
My above-ground pool is round and 32 feet across
AG is past its 30-foot rating. B1 still needs full fit verification, although the area is under its headline limit.
- Dolphin Nautilus AG
- Not suitable
- WYBOT B1
- Depends
I need walls and the waterline cleaned
B1 documents both additional routes, while AG is floor-only.
- Dolphin Nautilus AG
- Not suitable
- WYBOT B1
- Good
Battery recharging is out for me
B1 requires charging, whereas AG is corded.

I need weekly scheduling confirmed to run unattended
The technical table for AG lists no weekly timer, and no verified weekly schedule for B1 is established here.

In practice
Differences you will notice
Checking round-pool area does not remove a length limit
About 804 square feet is the surface area of a round pool 32 feet across. That sits below B1's 1,150-square-foot headline but beyond Nautilus AG's 30-foot length limit, so rule out AG at that size. B1 stays conditional, because surface area alone does not verify its shape, depth, material or above-ground installation requirements. In a compatible smaller pool, coverage and charging are the clearer deciding factors.
How we worked this out
16 squared times pi comes to about 804 square feet. In this example, the diameter is the relevant maximum span. No maximum pool length for B1 is invented from its area label.
A floor-only cleaner leaves the walls as another job
The pool floor is the documented job of Nautilus AG. B1 adds floor, wall and waterline modes, which makes it the better starting point if the robot has to handle those additional surfaces. AG is the pick when a compatible above-ground pool needs only automated floor pickup and a powered setup is convenient. Neither coverage list promises that every liner, curve, slope or contaminant will respond the same way.
How we worked this out
What separates them is the cleaning role the manufacturer supports. Debris removal was not measured. B1's 180-micron filter specification says nothing quantitative about how well either machine scrubs residue.
A maximum battery time does not make it a scheduled appliance
B1 advertises up to 120 minutes of battery runtime and still needs recharging, while AG specifies a 90-minute powered cycle and no weekly timer. AG is the choice if getting rid of battery charging matters more to you than going cordless. B1 is the choice if cable-free operation and broader coverage justify the charging chore. Neither the extra 30-minute headline nor AG's powered connection establishes unattended multi-day cleaning with no owner care.
How we worked this out
The subtraction 120 minus 90 gives 30 minutes, yet maximum endurance and a fixed cycle measure different things. Emptying the filter and storing it where permitted still need the owner's attention.
Option A
Dolphin, 99996132-PC

Spec by spec
Where they really differ
| Spec | Dolphin Nautilus AG | WYBOT B1 | In practice |
|---|---|---|---|
| Pool sizing | The technical table rates above-ground pool length up to 30 feet. | The published pool-area limit is 1,150 square feet. | You cannot swap a length limit for a surface-area limit. |
| Coverage | Coverage is floor only. | Selectable cleaning includes floor, wall and waterline routes. | Documented wall and waterline routes are what B1 adds. |
| Duration basis | Its powered cleaning cycle is 1.5 hours. | Maximum battery runtime is 120 minutes. | Maximum battery endurance is not the same as a fixed powered cycle. |
| Power and scheduling | It is corded and has no app or weekly timer in the technical table. | The cleaner is cordless and requires recharging. | B1 needs charging, and the technical table gives AG neither an app nor a weekly timer. |
Trade-offs
What each pick costs you
With Dolphin Nautilus AG
- Pools up to 30 feet are all the technical table rates
With WYBOT B1
- Shape and material compatibility cannot be established from area alone
Change of plan
When the answer changes
Rely on a powered, floor-only 90-minute cycle
Go with Dolphin Nautilus AG. No battery has to be charged once its permitted operating period ends. Floor-only coverage means walls and waterline stay separate jobs.
Get modes for cleaning walls and the waterline
Go with WYBOT B1. Cordless operation works as long as the exact pool-fit requirements are met. Recharging is required.
Decision guide
How to decide
Nautilus AG suits a powered floor-only routine in a compatible above-ground pool up to 30 feet. WYBOT B1 suits documented wall and waterline routes when charging is manageable. The B1's 1,150-square-foot area label cannot be converted into a universal pool-length approval, and its two-hour maximum is not a measured cleaning advantage.
Checking round-pool area does not remove a length limit
Consider a round pool 32 feet across, which has about 804 square feet of surface area. That is under the B1 1,150-square-foot headline but over the 30-foot length limit of Nautilus AG, so rule out the AG at that size. The B1 stays conditional, because surface area alone does not verify its shape, depth, material or above-ground installation requirements. In a compatible smaller pool, coverage and charging are the clearer deciding factors. Pi times 16 squared is about 804 square feet. Diameter is the relevant maximum span in this example. No maximum B1 pool length is invented from its area label.
A floor-only cleaner leaves the walls as another job
The documented job of Nautilus AG is the pool floor. The B1 adds floor, wall and waterline modes, which makes it the better starting point when the robot has to handle those additional surfaces. Pick AG if a compatible above-ground pool only needs automated floor pickup and a powered setup is convenient. Neither coverage list promises that every liner, curve, slope or contaminant responds the same way. What separates them is the cleaning role the manufacturer supports. No debris-removal result was measured. The 180-micron filter specification of the B1 does not quantify how well either machine scrubs residue.
A maximum battery time does not make it a scheduled appliance
The AG specifies a 90-minute powered cycle and no weekly timer. The B1 advertises up to 120 minutes of battery runtime and still needs recharging. Pick AG if not having to charge a battery matters more than going cordless. Pick B1 if cable-free operation and broader coverage justify the charging task. Neither the extra 30-minute headline nor the AG's powered connection establishes unattended multi-day cleaning with no owner care. 120 minus 90 equals 30 minutes, but maximum endurance and a fixed cycle are different measures. Filter emptying and permitted storage still need your attention.
