What reviewers found
Wybot A1
- The Pool Nerd: Tested in the reviewer's flat container pool. Runtime was roughly 1 h against an advertised 2 h, suction struggled with large debris, and it only works on flat floors. Filtration beat the Aiper Seagull SE. Verdict Pool Nerd Disapproved. The site favors corded Dolphin robots and earns affiliate commissions. Source
- drohnen.de (3.7/5): German hands-on test with leaves, pebbles, insects and fine sand: good cleaning including fine particles, edge parking worked, but heavy soiling may need two cycles and fine dust in crevices was only partly removed. Lacks an app and wall cleaning. Source
Wybot S3
- Android Authority: 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. Source
- GadgetGuy (8.5/10): 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. Source
