- HTML version: https://robotsforthat.com/robot/wybot-s2/

## Verdict

A strong cleaner for big pools that PCWorld rated as effective as far pricier robots, missing just 1 of 100 test leaves. Navigation looks random and the app is rough, and the store page now claims a longer runtime than reviewers measured. Pick it for a large pool on a mid range budget; skip it if you want tidy, predictable cleaning paths.

## Pros

- Rated for pools up to 3,229 sq ft
- Left 1 of 100 test leaves in PCWorld testing
- Fairly light at about 19 lb
- Treads crossed a main drain without sticking

## Cons

- Random looking navigation with long pauses
- Cleaning history broken in PCWorld testing
- Runtime claims vary between sources
- Fine grit needs the optional second filter

## Specs

- pool types: Above-ground and in-ground (Wybot); max depth 9.8 ft (The Gadgeteer spec list)
- cleans: Floor, walls including tile, steps and waterline; 7 modes and 6 paths in the app, 3 on the robot (Wybot)
- power: Cordless, 25.9 V 7,800 mAh battery, triple motors plus a brushless motor, 90 W (Wybot, The Gadgeteer)
- runtime: Up to 210 min (Wybot store today); PCWorld measured about 2 h 45 min against a 3.5 h claim at the time; The Gadgeteer saw about 3.5 h
- charge time: About 3 h (Wybot, PCWorld)
- filter: Dual layer filtration, mesh plus a removable foam filter (Wybot, The Gadgeteer); PCWorld found fine grit needed the secondary filter, which is not installed by default
- max pool size: Up to 3,229 sq ft (Wybot)
- app: Wybot app over Wi-Fi with OTA updates and scheduling up to 4 cycles per 7 days; PCWorld found the cleaning history never worked

## Questions buyers ask

### Does it come with a charging dock?

The S2 sold alone on Wybot's US store parks near the wall for pickup with a hook. Reviewers who tested the S2 Pro bundle got an inductive dock it returns to on its own.

### How long does it really run?

Wybot now lists up to 210 minutes. PCWorld measured about 2 h 45 min, and The Gadgeteer about 3.5 h.

### Does it catch fine dirt?

PCWorld found it did only with the secondary foam filter installed, which is not fitted by default.
