The judges have ruled
Beatbot Sora 30 4-in-1 Cordless Robotic Pool Cleaner took this fight in our Middleweight division showdown.
Ringside notes
These two met in our Middleweight division fight, and as of July 2026 the ruling has changed hands: the Sora 30 now holds the belt. The reversal came from re-reading both listings on the same day rather than comparing numbers taken months apart. The Scuba S3's owner score fell from 4.7★ to 4.3★ — and the larger 145-rating base behind it is pooled from several countries and padded with Amazon Vine reviews written by people who received the robot free. The Sora 30's 4.4★ across 259 ratings (October 2026) comes entirely from US buyers who paid. On top of that, the S3's most common owner complaint lands on the thing it's marketed for: the cleaning pattern leaves uncleaned strips where it turns and skips the far and shallow ends. The Sora 30's counterpunch was always reach and stamina — 3,229 sq ft of claimed coverage and a 270–300 minute runtime against the S3's ~1,615 sq ft and 180–240 minutes, at a similar price — and it now leads on owners as well. The honest catch against it is unchanged and real: the one rigorous independent test panned its build and cleaning, and its advertised 3-micron fine filter isn't in the box — it ships with a 150-micron basket, and Beatbot sells the 3-micron basket separately. The S3 keeps the better filter and the longer eco runtime; if those are your priorities, it's still the buy. Both batteries are effectively sealed.

What would decide it
- Owner proof: Aiper Scuba S3 Cordless Robotic Pool Cleaner reads 4.5★ across 115 owners; Beatbot Sora 30 4-in-1 Cordless Robotic Pool Cleaner reads 4.4★ across 259. Depth of sample matters as much as the star.
- The money: Aiper Scuba S3 Cordless Robotic Pool Cleaner streets ~$650, Beatbot Sora 30 4-in-1 Cordless Robotic Pool Cleaner ~$699 — MSRPs, not sale lows, decide the tier.
- The hidden consumable: Aiper Scuba S3 Cordless Robotic Pool Cleaner battery — Sealed; Beatbot Sora 30 4-in-1 Cordless Robotic Pool Cleaner — Not stated. A robot whose battery can't be replaced IS the consumable.
- Aiper Scuba S3 Cordless Robotic Pool Cleaner — your pick if: filtration and runtime are what you're optimising for — 3 µm and up to 240 minutes, in the lightest body to lift out — and your pool is a simple shape, since the recurring owner complaint is uncleaned strips and skipped ends on freeform pools.
- Beatbot Sora 30 4-in-1 Cordless Robotic Pool Cleaner — your pick if: you want big coverage and long runtime backed by the strongest owner record in cordless (4.4★/259 all verified US purchases, no free-product reviews padding it) — just know the one rigorous test panned the build, so owners and testers disagree.

“I've had five corded Dolphin robot cleaners in the past 20 years. The last one was the top of the line costing $1500. It cleaned the pool bottom ok, never cleaned the pool walls, and made no attempt to clean the stairs. Sora 30 has been fantastic at cleaning the pool floor, scrubbed the walls, and works its way up and down the stairs.”
“After two weeks testing the Beatbot Sora 30 in our test pool, I cannot recommend it.”

Pro review “After two weeks testing the Beatbot Sora 30 in our test pool, I cannot recommend it.”— Justin D., The Pool Nerd
- 4.4★ across 259 Amazon ratings, every one we could read a US verified purchase — with up to 300 min of floor-only run time and big claimed coverage (3,229 sq ft), at ~$699 in either colour
- 4-in-1 cleaning (floor, walls, waterline, shallow) with 13-sensor navigation and a 2-year warranty
- Light-touch value: it's the easiest way into a current, waterline-capable cordless robot
- The one serious independent test (The Pool Nerd) was negative — cheap-feeling build, weak and slow cleaning, poor wall and step performance — and rated it 'disapproved'; owners disagree, but the tester gap is real
- The box ships with a 150-micron basket; Beatbot's 3-micron basket is sold separately (in stock on Beatbot's store at our 8 October read), and the 6,800 GPH suction is a brand claim testers found optimistic
- Battery replaceability isn't documented — treat it as another sealed-ish consumable until Beatbot confirms otherwise
Two complaints recur equally in the newest critical reviews: units that stop charging within weeks of delivery, and cleaning that falls short of the listing on fine dust, walls and the waterline.

Aiper Scuba S3 Cordless Robotic Pool Cleaner
3-micron filtration, lightest to liftYour pick if filtration and runtime are what you're optimising for — 3 µm and up to 240 minutes, in the lightest body to lift out — and your pool is a simple shape, since the recurring owner complaint is uncleaned strips and skipped ends on freeform pools.
- 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
- 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.

FAQ
Which is better, the Aiper Scuba S3 or the Beatbot Sora 30?
As of July 2026 our Middleweight fight rules for the Beatbot Sora 30. It has the better owner record (4.4★/259 at our October 2026 read, all from US buyers who paid) and, more importantly, a cleaner one: the S3's base as it then stood was pooled across countries and included a substantial share of free-product Vine reviews. That gap has since widened in a way that is easy to misread: the S3's Amazon listing died and was re-listed in September 2026, then again in October, and now shows 4.5★/115, a higher number on a base that is global, mostly free-product Vine reviews, and carries just two critical reviews — so we do not rank on it. The S3 keeps the finer 3 µm filter and longer eco runtime, so it's still the pick if filtration is your priority.
Why did the verdict change?
We re-read both Amazon listings on the same day in July 2026, which is the only way to compare fairly. The S3 had drifted from 4.7★/75 to 4.3★ across 145 ratings while the Sora 30 read 4.6★ across 94; by our August re-read the S3 stood at 4.3★/116 and the Sora 30 at 4.5★/217. Reading the reviews rather than just the averages showed the gap was wider than a tenth of a star: roughly a third of the S3's visible reviews were free-product Vine ones from outside the US, and its recurring complaint is incomplete coverage — the capability it's sold on.
Do the S3 or Sora 30 have replaceable batteries?
No on both, practically speaking. The S3's battery is sealed, and Beatbot doesn't document replaceability on the Sora 30, so treat it as sealed too. The division's third contender, the WYBOT S2, has a user-serviceable battery, but WYBOT no longer sells a genuine replacement pack — and owners report that battery failing early. For a battery-free machine, go corded.
