Quick Answer: The WYBOT S3 is WYBOT’s new flagship robotic pool cleaner, launched in April 2026 at $2,499.99 during presale (regular price $2,999.99, per Gadget Review). It’s the brand’s first robot with a self-emptying dock — debris transfers automatically into a 10-liter bin — and the first with full 3D pool mapping built from a 36-sensor array that learns your pool’s floor, walls, waterline, steps and depth changes on the first cycle. Dual-layer filtration, an AI-guided app, and solar-or-DC dock charging round it out. It’s a genuinely more automated system than anything else WYBOT sells, but the price and a fussier dock-placement setup mean it’s not the right buy for most owners.
WYBOT built its reputation on undercutting Dolphin and Beatbot on price. The S3 is a different pitch entirely: it’s WYBOT’s first attempt at a true set-and-forget flagship, competing less with its own C1 and C2 Vision and more with premium self-emptying systems from Beatbot and corded robots like the Dolphin Premier. Below is the full review — verified specs, what the self-emptying dock and 3D mapping actually change day to day, and where the S3 fits against the rest of WYBOT’s lineup covered in our best WYBOT pool cleaner guide.

- 36-sensor array builds a full 3D map of the pool on the first cleaning cycle.
- Climbs walls and the waterline, and adapts to steps, ledges and depth changes.
- Dual-layer 180μm + 40 PPI filtration and a solar-or-DC charging dock.

By the numbers
- Presale pricing: WYBOT launched the S3 at $2,499.99 during presale, with a $2,999.99 regular price once the presale window closes, per Gadget Review’s coverage of the April 2026 launch — roughly $700 above the S2 Solar, WYBOT’s previous flagship.
- Sensor array: The S3 maps the pool using 36 sensors, per Android Authority’s hands-on coverage — nearly double the sensor count WYBOT lists for the S2 Solar’s navigation system, and the basis for the S3’s first-cycle 3D map.
- Debris capacity: The self-emptying dock stores collected debris in a 10-liter bin, per WYBOT — large enough that most owners won’t need to empty it after every single cleaning cycle, unlike a robot’s onboard basket.
- Filtration: Dual-layer filtration pairs a 180μm filter box with a 40 PPI sponge, per WYBOT, catching both larger debris and fine particles in the same pass.
What it does well
Self-emptying is a real quality-of-life change. Every other robot in WYBOT’s lineup — and most cordless robots on the market — require you to lift the unit out, open the basket, and rinse it after each run. The S3’s dock automates that step, transferring debris into its own 10-liter bin so the robot itself needs far less hands-on attention between cleans.
3D mapping is more than a buzzword here. With 36 sensors building a full map on the first cycle, the S3 learns depth changes, stairs and ledges rather than treating the whole pool as one flat surface — a genuine step up from the sensor-only or camera-only navigation on the C2 Vision and S2 Solar, and the app’s real-time map view makes it easy to confirm coverage.
Flexible dock charging. Supporting both solar and DC power gives owners a choice the S2 Solar doesn’t — DC as a reliable primary source with solar as a supplement, rather than depending on sunlight alone.
Wall, waterline and depth-change coverage. Android Authority’s hands-on testing confirmed the S3 navigates walls and the waterline without getting stuck, and adapts cleanly to pools with varying depths — the areas where cheaper robots most often struggle.
Where it falls short
- Setup is genuinely more involved. Android Authority flagged the S3’s setup as more complex than a traditional drop-in cordless robot, and initial setup may require getting in the pool yourself to position the dock and calibrate the mapping.
- Dock placement is critical, not optional. The dock needs a permanent location with AC power access and enough clearance for the robot to approach and dock reliably. Insufficient space in shallow areas can affect how consistently it docks — this isn’t a robot you can just toss in and forget where the base sits.
- Premium pricing puts it out of reach for most buyers. At $2,499.99 presale and $2,999.99 regular, the S3 costs more than double WYBOT’s previous flagship and rivals Beatbot’s top-tier AquaSense 2 Ultra. Budget-conscious owners are far better served by the WYBOT C1 or C2 Vision.
- Unproven track record. As a just-launched model, the S3 doesn’t yet have the months of owner reviews and independent long-term testing that older WYBOT models like the C2 Vision have accumulated — early adopters are the ones finding any reliability issues first.
- Not for owners happy with manual retrieval. If you don’t mind lifting a robot out and rinsing a basket every few days, the self-emptying dock’s convenience premium is hard to justify.
WYBOT S3 vs the alternatives
| Model | Navigation | Self-emptying | Cleans | Price |
|---|---|---|---|---|
| WYBOT S3 | AI vision + 3D map, 36 sensors | Yes — 10L dock bin | Floor, walls, waterline | $2,499.99 presale / $2,999.99 |
| WYBOT C2 Vision | AI camera, floor-only | No — onboard basket | Floor, walls, waterline | ~$1,069 list |
| WYBOT S2 Solar | Standard sensors | No — onboard basket | Floor, walls, waterline | ~$1,799 |
| Beatbot AquaSense 2 Ultra | AI camera, HybridSense mapping | No — onboard basket | Floor, walls, waterline, surface, clarify | $3,150 list / ~$2,649 sale |
| Dolphin Premier | Standard sensors, corded | No — onboard basket | Floor, walls, waterline | ~$1,500 |
Within WYBOT’s own range, the S3 is a clear step above the C2 Vision and S2 Solar — both still require manual basket emptying, and neither builds a full 3D map. Against Beatbot’s AquaSense 2 Ultra, the closest competitor on price and ambition, the S3 counters with self-emptying (which the Ultra lacks) while the Ultra counters with surface skimming and water clarification the S3 doesn’t do; see our full WYBOT vs Beatbot comparison for the broader brand matchup. Against the corded Dolphin Premier (~$1,500), the comparison is straightforward: the Premier is $1,000 cheaper and never needs docking calibration, but it has no self-emptying, no mapping, and requires a permanent plumbing connection the S3 doesn’t need.

Who should buy the WYBOT S3
Buy it if you want the most hands-off pool cleaner WYBOT has ever built and are willing to pay flagship pricing and accept a more involved one-time setup for it. The self-emptying dock and 3D mapping are real, working upgrades over every other WYBOT model, and it’s a strong pick for owners who found the C2 Vision’s weekly battery rationing frustrating.
Skip it if you’re comfortable with normal basket-emptying — the WYBOT C1 or C2 Vision clean nearly as thoroughly for well under half the price. Owners who also want surface skimming and water clarification should compare the Beatbot AquaSense 2 Ultra before committing to the S3, and anyone leaf-heavy should check our best pool cleaner for leaves guide first.
The bottom line
The WYBOT S3 is a genuine flagship — the brand’s first robot with a self-emptying dock and true 3D pool mapping, backed by a 36-sensor array and dual-layer filtration. At $2,499.99 presale, it’s priced to compete with Beatbot’s top tier rather than WYBOT’s own budget-friendly reputation, and the dock-placement requirements make setup meaningfully more involved than a drop-in cordless robot. It earns a solid ★★★★: an impressive, genuinely more automated cleaner for owners who want the least hands-on pool maintenance possible and can justify the price — everyone else is still better served by the far cheaper C2 Vision or C1.
