What reviewers found
Aiper Scuba S1
- Reviewed: In a roughly 1,200 sq ft pool it climbed walls well and covered most of the pool, but left leaves behind and needed four cycles for a spotless pool; drying the charging port was a chore. Source
- The Smart Home Hookup: Ran 3 h 56 min against 150 min listed with about 95% wall and floor coverage, the best in the group, but its rear suction stirred up leaves. 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
