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 S2
- PCWorld: Picked up 99 of 100 synthetic leaves and captured organic debris and grit well with the secondary filter fitted. Ran about 2 h 45 min against a 3.5 h claim, moved in a haphazard pattern, and the app's cleaning history was unavailable throughout testing. Source
- The Gadgeteer: Tested the S2 Pro bundle with a self charging dock. Ran about 3.5 h, left the pool visibly cleaner, agitated the surface even at the 9 ft deep end, and its treads did not stick on the main drain. The dock bracket mounts permanently with adhesive. Source
