Quick Answer: The WYBOT B1 is a cordless robotic pool cleaner priced at $334.93 on sale (list $399.99, per wybotpool.com), covering pools up to 1,150 sq ft with up to 120 minutes of runtime per charge. It cleans floors, walls, and the waterline across five modes, and hands-on testing from Popular Science found it lightweight (about 13 lbs), quick to set up, and effective at tracking corners and sloped walls — without the independent-test red flags that have dogged some cheaper WYBOT models.
WYBOT’s lineup now spans from the sub-$150 Osprey 200 up to the self-emptying, 3D-mapping S3 near $2,500. The B1 sits in the lower-middle of that range — a step up from floor-only budget bots, without the premium price of the C1 or C2 Vision. Here’s what the pricing and testing show.

By the numbers
- Real discount, not list-price inflation: WYBOT’s own store prices the B1 at $334.93, down from a $399.99 list — a genuine 16% cut confirmed directly on wybotpool.com, not a marked-up “sale” figure.
- Setup speed: Popular Science’s hands-on test clocked setup at under 5 minutes — no hose, cord, or pump connection to manage.
- Weight: At about 13 lbs dry, per Popular Science’s test, it’s among the lighter cordless robots on this site — easier to lift out solo than the 17-25 lb models common in the mid-tier and flagship classes.
- Coverage gap vs the C1: WYBOT rates the B1 for up to 1,150 sq ft, noticeably below the WYBOT C1’s 1,614 sq ft rating — a real limitation for larger pools, not just a marketing distinction.
What it does well
Genuinely cordless convenience. No cable to thread, coil, or trip over — Popular Science’s reviewer called out eliminating “cord management hassles” as the single biggest quality-of-life win over corded robots.
Real wall and waterline cleaning. Unlike WYBOT’s cheapest model, the floor-only Osprey 200, the B1 climbs walls and cleans the waterline, with dedicated edge-to-edge side brushes that independent testing found handled corners and sloped walls well.
Modular, tool-free maintenance. Filter and component swaps don’t require tools, per the hands-on test — a real advantage for anyone who’ll be doing routine maintenance themselves.
Self-parking retrieval. It surfaces at the pool wall when a cycle ends, with an included retrieval hook, so you’re not fishing it off the bottom.
Where it falls short
- Smaller coverage than the C1. At 1,150 sq ft, larger in-ground pools will need multiple cycles or should size up to the C1 instead.
- 120 minutes may mean multiple charge cycles. For bigger pools within its rated coverage, a single charge might not finish the job — charging only happens between cycles, not during operation.
- Just a 1-year warranty. In line with most budget-to-mid WYBOT models, but shorter than the 2-3 year warranties on premium corded and cordless robots like the Dolphin Nautilus CC Plus or Beatbot AquaSense 2.
- No independent lab test score yet. Unlike the C1 or Osprey 200, Robotic Reviews hasn’t published a numeric score for the B1 as of this review — the Popular Science hands-on test is positive, but it’s not the same as a full lab-style evaluation.
WYBOT B1 vs the alternatives
| Model | Coverage | Runtime | Cleans | Price |
|---|---|---|---|---|
| WYBOT B1 | ~1,150 sq ft | Up to 120 min | Floor, walls, waterline | $334.93 |
| WYBOT C1 | 1,614 sq ft | Up to 150 min | Floor, walls, waterline | $429.99 |
| WYBOT Osprey 200 | ~538 sq ft | ~1 hr | Floor only | Under $150 |
| Aiper Seagull SE | ~850 sq ft | ~90 min | Floor only | $249 |
Against its closest sibling, the WYBOT C1 covers about 40% more pool area and runs 30 minutes longer for roughly $95 more — worth it if your pool is on the larger side of “residential.” Against the rock-bottom WYBOT Osprey 200, the B1 costs more but actually cleans walls and the waterline instead of floor-only, and independent testing flagged real durability concerns on the Osprey 200 that haven’t surfaced with the B1.

Who should buy the WYBOT B1
Buy it if you have a small-to-medium above-ground or in-ground pool (up to ~1,150 sq ft) and want real floor, wall, and waterline cleaning in a lightweight, easy-to-lift package without paying C1 or flagship prices.
Skip it if your pool is larger than 1,150 sq ft — the WYBOT C1 is the better fit — or if you only need floor cleaning on a small flat-bottom pool, where the far cheaper WYBOT Osprey 200 or Aiper Seagull SE will do the job for less.
The bottom line
The WYBOT B1 is a solid mid-tier cordless pick: real wall and waterline cleaning, a genuinely lightweight build, and independently-tested ease of setup, all for under $335 on sale. It doesn’t match the WYBOT C1’s coverage, so measure your pool before buying — but for smaller above-ground and in-ground pools, it’s one of the more balanced budget-to-mid cordless robots WYBOT makes.
