Wybot S3
Cordless robot that docks, charges and empties itself underwater
Researched by Riley Hart · updated Nov 3, 2026
Is the Wybot S3 worth it? For owners who never want to lift a robot out of the pool or empty a basket every run: the S3 parks, charges and dumps debris into a dock bin by itself. It costs $3,000 as of Nov 3, 2026, and GadgetGuy scored it 8.5/10.
For owners who never want to lift a robot out of the pool or empty a basket every run: the S3 parks, charges and dumps debris into a dock bin by itself. Reviewers found it cleaned floors, walls and the waterline well, but setup takes work and the dock needs a fixed spot with enough room to approach. Skip it if you have a small pool or a normal budget.
Best for: hands off cleaning of large in-ground pools. Skip if: you have a small pool or a tight budget.
Specs
- Pool types

- Runtime
- Up to 2.5 h per GadgetGuy; Smart Home Fox reports about 3 h

What independent reviewers found
- Mapped the pool on the first run, climbed walls and scrubbed the waterline without getting stuck, and docked and emptied on its own. Docking was unreliable in a shallow area until the dock was moved to a spot with a longer approach; setup required getting into the pool.
- Android Authority
- Up to 2.5 h runtime and about 3 h mains charging; transferred debris to the 10 L dock cassette and lifted above the waterline on wall runs. Finer 180 µm and 10 µm filters do not clear through the auto transfer and need hosing about every two weeks. Value scored 6 of 10.
- GadgetGuy · 8.5/10

Questions buyers ask
Do I still need to empty the robot?
Not after each run. The robot dumps its 3 L basket into a 10 L dock bin, which Wybot says lasts up to about 30 days. The finer filters still need hosing out about every two weeks, per GadgetGuy.
Does it need an outlet by the pool?
It can charge from a solar kit, DC or AC. GadgetGuy found solar alone needs about three days of full sun between weekly cleans, and Android Authority notes the dock wants AC access for best results.
How big a pool can it clean?
The maker rating cited by reviewers is up to 300 sq m, about 3,230 sq ft. Wybot's US product page does not list a maximum.
