One of the cheapest cordless robots that still climbs walls and works the waterline, with no app to set up. The Smart Home Hookup found its coverage the best in a group test, but Reviewed needed several cycles to clear leaves. Charge it indoors or in shade and dry the port well.

Aiper's do it all model covers floor, walls, waterline and surface, with a big 5 L basket and a 3 year warranty. Digital Trends called it one of the best cleaners on the market, while The Pool Nerd found weaker suction than top corded robots. It suits big in-ground pools where you want no cord, but it is heavy to lift out.

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
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. Source
- 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
