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
Dreame Z1
- CyberShack (8.6/10): Ran 160 to 180 min in standard mode. A 20 m2 floor, 24 m2 wall and 24 m tile line test took 80 min and used 47% of the battery. Charged in 4 to 5 h and weighs 12.1 kg. Source
- The AU Review (3.5/5): Ran just under 3 h and charged in about 4 h. Strong suction, but missed tight corners, sometimes left debris on walls, moved slowly, and the remote and app connection were weak. Source
