Main trade-off
WYBOT B1
The 1,150-square-foot rating is below the larger C-series cleaners.
Head-to-head
B1 suits a smaller pool with ordinary debris. C2 adds much more rated area, an extra hour of maximum runtime and a 10-micron secondary filter for finer material.
Before you choose
Its limit is about 87 percent larger.
What this is based on
2152 minus 1150 equals 1002 square feet. 1002 divided by 1150 equals 87.1 percent.
Main trade-off
The 1,150-square-foot rating is below the larger C-series cleaners.
Main trade-off
At 17.6 pounds dry, it is heavier than simple floor-only cordless models.


Compare WYBOT B1 and C2 for pool-area limits, runtime, filter media and cleaning modes, with attention to the difference between ordinary debris and fine silt.
Winner by situation
C2 has the larger area rating.
C2 includes finer secondary media.
C2 lists up to three hours.
B1 covers the simpler requirement.
What matters in practice
Its limit is about 87 percent larger.
2152 minus 1150 equals 1002 square feet. 1002 divided by 1150 equals 87.1 percent.
Maximum runtime rises 50 percent while area rises about 87 percent.
180 divided by 120 minus 1 equals 50 percent. Coverage is a manufacturer rating, not a fixed square-feet-per-minute guarantee.
C2 adds a 10-micron stage to the shared 180-micron class.
180 divided by 10 equals 18 for nominal pore-size scale. This does not imply eighteen times better capture or water clarity.

What you give up
Recommendation switch
Choose neither. Advantage Ultra provides corded floor, wall and waterline cleaning.
What matters in practice
C2 provides a larger advertised area margin and more battery time. An irregular shape, slopes and wall work can consume more of a session, so the maximum area is only a starting fit check. Do not extrapolate the rated area into guaranteed one-pass coverage.
C2 finer secondary media is the clearer reason to step up when small particles pass through coarser baskets. It can also need more frequent rinsing as it loads. B1 is easier to justify when the recurring problem is ordinary leaves and grit in a smaller pool.
Both provide app-selected floor, wall and waterline work. C2 additional modes are useful only if they match the cleaning routine. Select the intended mode before submerging and follow the model guidance for scheduling, rather than assuming a continuous phone link underwater.
What the facts say
Useful conclusions from the current robot pool cleaners comparison, followed by the checked facts used to reach them.
None of the 27 models checked covers every part of “My pool is compact or under 33 feet”, “My pool is large or close to 50 feet”, “Fine dust, sand or dead algae settles in my pool”, and “I do not want a cable across the pool”, so the recommendation favors the closest practical compromise.
0 matching models from 27 checkedWYBOT C2 lists 180 min for published full cleaning cycle, 50% above WYBOT B1 at 120 min.
Match countThe count uses the current product-to-need assignments for “My pool is compact or under 33 feet”, “My pool is large or close to 50 feet”, “Fine dust, sand or dead algae settles in my pool”, and “I do not want a cable across the pool”. A need with no documented match does not count.
