What reviewers found
Aiper EcoSurfer S2
- 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
- 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
Betta SE Plus
- The Pool Nerd: Used in the reviewer's own pool; the surface was clear of leaves, bugs and trash after a few hours, and he went weeks without skimming by hand. Rated Pool Nerd Approved. Says little changed from the SE beyond backup charging, for about $30 more. The site earns affiliate commissions. Source
- Bob Vila (tested) (4.6/5): Best Overall of seven skimmers tested over about two months in residential inground pools. Easy to set up and removed more leaves and floating debris than any other model. Rated ease of use 5/5, performance 4.9/5, value 4/5. The tester's earlier Betta SE stopped working after about 12 months. Source
