## 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](https://reviewed.com/home-outdoors/content/aiper-scuba-s1-robotic-pool-cleaner-review)
- 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](https://www.thesmarthomehookup.com/?p=5626)

### Aiper Scuba X1 Pro Max

- Digital Trends: Editors' Choice. Floor and wall cleaning was about 90% effective and it never got stuck, with stronger suction than a Beatbot AquaSense Pro; skimming underperformed and it climbed only 0.5 to 1 inch above the waterline.

- The Pool Nerd: Rated Pool Nerd Disapproved: measured weaker suction than top corded robots, fine sediment remained after several passes, and it needed 4 to 5 hours of charging after each session. [Source](https://www.thepoolnerd.com/aiper-scuba-x1-pro-max-review)
