Head-to-head

WYBOT B1 vs C2: C2 adds a fine secondary filter for smaller debris

The short answer

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

The reasoning and the trade-offs

C2 nearly doubles the rated pool area

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

WYBOT B1

The 1,150-square-foot rating is below the larger C-series cleaners.

Main trade-off

WYBOT C2

At 17.6 pounds dry, it is heavier than simple floor-only cordless models.

About this comparison

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

Start with what you need it to do

  • Pool area exceeds 1,150 square feet and is no more than 2,152 square feet

What matters in practice

The differences that matter

C2 nearly doubles the rated pool area

Its limit is about 87 percent larger.

How we reached this conclusion

2152 minus 1150 equals 1002 square feet. 1002 divided by 1150 equals 87.1 percent.

Runtime grows less than rated area

Maximum runtime rises 50 percent while area rises about 87 percent.

How we reached this conclusion

180 divided by 120 minus 1 equals 50 percent. Coverage is a manufacturer rating, not a fixed square-feet-per-minute guarantee.

The secondary filter changes the debris target

C2 adds a 10-micron stage to the shared 180-micron class.

How we reached this conclusion

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

Every choice has a cost

If you choose WYBOT B1

  • Its 180-micron filter favors ordinary debris over very fine dust.

If you choose WYBOT C2

  • Battery charging adds downtime between long cycles.

Recommendation switch

The decision flips if...

You want full-zone cleaning without battery recharge cycles

Choose neither. Advantage Ultra provides corded floor, wall and waterline cleaning.

What matters in practice

How to make the call

01

For a pool near the B1 limit

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.

02

For dust that settles after every swim

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.

03

For mode selection

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.

Check these before buying

  • Check the exact model year, pool surfaces, dimensions, depth and operating conditions against the manual.
  • Compare included filter media, charging hardware and caddy contents for the exact offer.
  • Plan safe retrieval, filter rinsing and storage after each cleaning session.

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.

What the facts say

What the comparison shows

Useful conclusions from the current robot pool cleaners comparison, followed by the checked facts used to reach them.

Compared set

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.
