## 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)

### Beatbot iSkim

- Reviewed: Five days in a windy above-ground pool flanked by trees; the tester never needed a hand skimmer and the 9 L basket never overflowed between daily checks. Downsides were the missing charger and an app remote that takes practice. Editors' Choice badge. [Source](https://www.reviewed.com/cleaning/content/beatbot-iskim-review-robot-pool-skimmer)
- Android Authority: Hands-on with a Sora 30: charged itself by sun after an initial plug in of a couple of hours in a sunny desert test, and covered about 80 sq m in a couple of hours. Lacks the Ultra's S-path and clarifier. [Source](https://www.androidauthority.com/beatbot-sora-30-iskim-due-hands-on-3690811/)
