Robotic Pool Cleaners matchup
Aiper Scuba S1 vs Aiper Scuba S3 Cordless Robotic Pool Cleaner
proof volume vs the newest star
Different weight classes
These two fight in different divisions — this is a budget question, not a fair fight. The tale of the tape below shows what stepping up (or down) actually buys.
Ringside notes
Aiper against itself: the robot with the deepest proof in cordless versus the brand's best-rated machine. The S1 at ~$550 is the known quantity — 4.2★ across 856 owners, the largest verified base on our board, happiest in light-debris pools up to ~1,600 sq ft on standard 180 µm mesh (a 3 µm MicroMesh filter is an optional add). The S3 at ~$900 was the Middleweight champion until the Beatbot Sora 30 took the belt in July 2026: 4.7★, genuinely fine 3 µm filtration standard, 4,800 GPH suction, and dToF sensor navigation. The $350 buys real hardware — but the honest tale of the tape says what it doesn't buy: coverage barely moves (~1,615 vs ~1,600 sq ft), the S3's stellar rating sits on a young 75-owner base with no independent lab test yet, and its battery is sealed where the S1's is at least no worse (undocumented on both). Small pool, light debris, value-first: the S1's 798 owners are the argument. Haze, silt, fine debris: the S3's standard 3 µm filter is exactly the tool — but the Beatbot Sora 30 has since taken the Middleweight belt from it.

What would decide it
- Owner proof: Aiper Scuba S1 reads 4.5★ across 804 owners; Aiper Scuba S3 Cordless Robotic Pool Cleaner reads 4.3★ across 145. Depth of sample matters as much as the star.
- The money: Aiper Scuba S1 streets ~$500, Aiper Scuba S3 Cordless Robotic Pool Cleaner ~$900 — MSRPs, not sale lows, decide the tier.
- The hidden consumable: Aiper Scuba S1 battery — Not stated; Aiper Scuba S3 Cordless Robotic Pool Cleaner — Sealed — not replaceable. A robot whose battery can't be replaced IS the consumable.
- Aiper Scuba S1 — your pick if: you want the most owner-proven pick in cordless value — 4.5★ across 804 owners at about $500 — and you'd rather sidestep WYBOT's brand risk; best for light-debris pools, not heavy silt or the biggest pools.
- 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.

Aiper Scuba S1
Best valueYour pick if you want the most owner-proven pick in cordless value — 4.5★ across 804 owners at about $500 — and you'd rather sidestep WYBOT's brand risk; best for light-debris pools, not heavy silt or the biggest pools.
“I picked up a S1 a few weeks ago and have been very impressed. It cleans just as good as my old Maytronics, for half the price and no cord.”— JJ_Tex, verified owner (Trouble Free Pool)
- Excellent price-to-performance
- Cleans the waterline too
- Long runtime for the price (~270 min floor-only; ~150 min combined)
- Easy to live with
- Testers ding fine-debris pickup on very silty pools
- Best for light-debris pools; weaker than corded models
- Navigation/app less refined than the premium tier

Aiper Scuba S3 Cordless Robotic Pool Cleaner
Best owner-ratedYour 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.
“Cleans my pool surface a lot better than my Dolphin. Pool wall and waterline cleaning is very thorough. The water in my pool is more clear now too from using the micro filter… The ten minute hover at the surface after cleaning is a bit hit and miss. It seems like the unit can't connect to WiFi quick enough after popping up at the waterline to send the alert through the app.”— William Edward Mohr, Amazon
- The highest owner rating here — 4.7★ across 75 Amazon ratings — with the longest run time (up to 240 min in eco mode) and a fine 3-micron filter
- 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 WYBOT S2 or Beatbot Sora 30

FAQ
What does the Aiper Scuba S3 add over the S1?
Standard 3 µm ultra-fine filtration (the S1 runs 180 µm with a 3 µm filter as an optional extra), 4,800 GPH suction, dToF sensor navigation, and the best owner rating in cordless (4.7★). Coverage stays essentially the same (~1,600 sq ft class).
Is the S3's 4.7★ more trustworthy than the S1's 4.4★?
It's higher but younger: 75 owners against the S1's 798 — the deepest base we track. Both are real, dated Amazon reads. Confidence-per-review favors the S1; peak performance and filtration favor the S3.
Which should a first-time robot buyer pick?
Match the pool: light debris and a small-to-mid pool, the S1 at ~$550 is the most owner-proven money in cordless. Fine silt, pollen haze, or algae dust, the S3's standard 3 µm filter is the difference you'll actually see in the water.
