The one spec that makes WYBOT worth knowing
The C2 publishes a dual filter: a 10-micron fine layer behind a 180-micron coarse layer, at around $500. Nothing else under $500 publishes a fine filtration figure anywhere near that, and only Aiper’s 3-micron flagships at $800+ beat it.
The staging is as important as the number. A single very fine filter in a real pool blinds within one cycle, because leaf fragments plug the mesh long before sediment fills the basket — at which point flow collapses and your fine-filtration machine performs worse than a coarse one. A coarse layer in front keeps the fine layer flowing. The filtration explainer sets out why staging beats a better headline number, and the sand and silt roundup ranks on exactly this.
The range
| Model | Positioning | Key published spec |
|---|
| B1 | Cheapest wall climber | Quad roller brushes, high obstacle crossing |
| C1 | Best runtime per dollar | 160 min, both pool types, app control |
| C2 | The one to buy | 10 + 180 micron dual filter, 2,152 sq ft/cycle |
| C2 Vision | Camera plus waterline | AI camera, floor-to-waterline |
| S2 Vision | The flagship | AI camera, brushless motor, horizontal waterline |
Two more things WYBOT gets right
The brushless motor on the S2 Vision
A machine that spends hundreds of hours submerged in chlorinated water has no business using a brushed motor with a commutator to wear. WYBOT publishes brushless on the S2 Vision, which is the correct engineering choice and one most competitors at this price do not make.
Camera navigation at a low price
The C2 Vision at around $630 and the S2 Vision at around $900 are the cheapest camera-navigated machines here. On a freeform, kidney-shaped or multi-level pool, where pattern navigation leaves the same gaps every cycle, that is real value.
The disclosure problem, which is the brand’s main weakness
WYBOT publishes a micron figure on the C2 and on nothing else. The S2 Vision at $900 describes filtration qualitatively. The C2 Vision drops the explicit 10-micron claim its own cheaper sibling makes. The B1 publishes no weight, no runtime, no rated area and no filter rating.
For a buyer trying to compare machines on paper, that is genuinely frustrating. We mark every omission as an omission on each product page rather than carrying a figure across from a different model — and on a brand this inconsistent, that discipline matters.
Track record and parts
WYBOT has been in this market less time than Aiper and far less than Maytronics, so owner-report depth is thinner. The encouraging counter-signal is that a third-party ecosystem has already started: a 6 Ah replacement pack for the C1 at around $69, 25.2 V chargers at around $17, and ultra-fine filter elements for the C2 at around $23.
On a cordless machine, the availability of a replacement pack is the question that determines its life, so that is a meaningful positive — the battery section lists what exists. Verify availability for the S2 and B1 specifically before assuming.
Which WYBOT to buy
- Fine debris under $500: C2. The whole reason to consider the brand.
- Above-ground pool, best runtime: C1. 160 minutes, both pool types, and a replacement battery exists — our top above-ground pick.
- Cove is visibly the problem, tight budget: B1.
- Freeform pool on a budget: C2 Vision.
- Freeform pool, want the waterline too: S2 Vision — but compare against the Aiper Obsidian, which publishes 3-micron filtration and a dock for less. The head-to-head is here.
