## What reviewers found

### Aiper EcoSurfer S2

- PCWorld: Cleared synthetic leaves in about 3.5 h with roughly 80% collected by the robot. 24 h of nonstop running used about 25% of the battery, and it kept a 10 h daily schedule through weeks of overcast weather. Slow, slightly underpowered, and the basket is hard to remove. [Source](https://www.pcworld.com/article/3125386/aiper-ecosurfer-s2-review.html)
- 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](https://www.bobvila.com/reviews/best-robotic-pool-skimmer/)
- 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](https://www.thepoolnerd.com/best-pool-skimmers)

### 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](https://www.bobvila.com/reviews/best-robotic-pool-skimmer/)
- 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](https://www.thepoolnerd.com/betta-se-review)
- The Pool Nerd: Best Overall in its April 2026 skimmer roundup at about $370; estimated it delivers about 80 to 90% of the cleaning of skimmers costing twice as much. [Source](https://www.thepoolnerd.com/best-pool-skimmers)
