## 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)

### Seauto Shark

- PCWorld: Picked up about 85% of organic debris and over 90% of artificial leaves in a 3+ hour floor only run, scrubbed the tile line well, and docked at the wall every time. The app was buggy and a firmware update never completed. [Source](https://www.pcworld.com/article/2287110/seauto-shark-robot-pool-cleaner-review.html)
- Pro Tool Reviews: In a 20,000 gallon in-ground pool it ran more than 3 h in floor only mode, about 5 h total, recharged in 2 to 3 h, crossed raised drain covers and cleaned in a linear pattern. The app kept disconnecting. [Source](https://www.protoolreviews.com/?p=135996)
