What reviewers found
Aiper EcoSurfer S2
- Bob Vila (4.5/5): Named Best With App. Picked up leaves and bugs well and was compact, but app pairing was difficult at first and it sometimes got stuck after head on wall hits. Subscores: Ease of Use 4.3/5, Performance 5/5, Value 4/5. Source
- The Pool Nerd: Budget option at $299 with no approval badge; leaves often slipped past or sank, and the author suggests paying about $70 more for the Betta SE. Notes the S2 is not part of Aiper's Seagull Pro or Elite Pro recalls. Source
Betta SE
- Bob Vila (4.6/5): Named Best Basic. Called it the fastest skimmer tested, with solar charging that kept it running and ultrasonic navigation that rarely left it stuck. It occasionally missed tight corners, and the test unit's rear propellers stopped working after about 12 months (covered by warranty). Subscores: Ease of Use 5/5, Performance 5/5, Value 5/5. Source
- The Pool Nerd: Pool Nerd Approved and named Best Overall Pool Skimmer. Cleared the surface within a few hours, ran daily for several weeks with no jams, and the basket needed emptying every few days. The site earns affiliate commissions. Source
