Aiper Scuba S3 Cordless Robotic Pool Cleaner
3-micron filtration, lightest to lift — 3 µm filtration and up to 240 minutes in eco mode (the Scuba V3 matches both), and the lightest to lift — and its Amazon listing was RE-LISTED under a new ASIN in September 2026 showing 4.5★ across 115 global ratings — a number we deliberately do not rank on, because it is pooled across two ASINs and carries exactly one critical review, which is itself Vine. The most common complaint on the older, readable base was that it misses parts of the pool, and its battery is sealed (you can't replace it)

Filtration is rated in microns (µm — millionths of a meter): the smallest particle the filter reliably traps, so a lower number is a finer filter. A human hair is ~70 µm; ultra-fine (~3–10 µm) catches the silt and dead algae that make water hazy. "µm not published" means the maker states no number — which is information in itself.
Pros
- Up to 240 min in eco mode and a 3-micron ultra-fine filter (Aiper rates the Scuba V3 the same). Its listing shows 4.5★ across 115 and we deliberately do NOT rank on it: the old listing died, this is a fresh one, the ratings are GLOBAL, the identical 4.5★/115 appears on a second ASIN, and the only critical review in existence on it is an Amazon Vine free-product card. The Beatbot Sora 30 keeps the owner-rating belt on 217 verified US ratings
- JetAssist waterline scrubbing, climbs walls, sensor (dToF) navigation, and light to lift at 18 lbs
- 4,800 GPH suction and a 2-year warranty
Cons
- Brand-new 2026 model with no independent lab review yet — owners love it, but it hasn't faced the harder-testing reviewers, and Aiper's older Scuba S1 was panned by them
- Sealed battery you can't replace — when it degrades in a few years, the whole robot becomes the consumable (the hidden cost, made literal)
- Smallest rated coverage of the three (~1,615 sq ft) — a big pool wants the Beatbot Sora 30
Coverage gaps: the nav pattern leaves strips at the turns and untouched areas in the shallow end.

✓ Safety: no active recall — No active CPSC recall on this model (CPSC recall API queried by ProductName=Aiper on 2026-09-12: two records, both other models). Aiper's recalls cover the Seagull Pro ZT6001 (2025-03-20) and the Elite Pro GS100 (2023-08-24), both adapter/charging burn-and-fire hazards — neither is the Scuba series. Standard lithium-battery care applies.
