Quick Answer: The eufy Omni S2 is eufy’s new 2026 flagship, launched January 20 at $1,599.99 with a huge suction jump to 30,000 Pa via its new AeroTurbo 2.0 motor — nearly 4x its predecessor’s 8,000 Pa, per T3 and Tom’s Guide. It pairs that with a HydroJet 2.0 self-washing roller mop and a 12-in-1 dock (empty, wash, dry, water refill, hot-water sterilization, plus a fragrance diffuser). Tom’s Guide measured an 89.25% overall cleaning score, but both Tom’s Guide and T3 independently flagged navigation as the one place it falls short of top rivals despite the new “CleanMind AI” camera system. Verdict: a genuinely strong suction-and-mop flagship, held back from best-in-class only by mapping polish.
Every eufy Omni generation has led with one headline spec, and the Omni S2 leads hard: 30,000 Pa of suction is nearly 4x the 8,000 Pa that made the eufy S1 Pro a mopping specialist rather than a carpet monster. That single number reframes what the Omni line is for — this is no longer just “the roller-mop robot,” it’s eufy’s answer to Roborock’s Saros flagships on raw power, with the self-washing roller mop layered on top. This review breaks down whether the $1,599.99 flagship earns its price, and where two independent reviewers agree it still comes up short.
eufy Omni S2 by the numbers
- 30,000 Pa — AeroTurbo 2.0 motor suction, roughly 4x the S1 Pro’s 8,000 Pa, per T3 and Tom’s Guide.
- $1,599.99 — launch MSRP, $100 above the S1 Pro’s original $1,499.99, per T3.
- 89.25% — Tom’s Guide’s measured overall cleaning score in independent testing; 84% specifically on pet hair.
- 87% vs 61% — embedded-sand removal on carpet, Omni S2 versus S1 Pro, per VacuumWars/Gear Live comparative testing — the clearest evidence the suction jump translates to real cleaning.
- 12-in-1 dock — self-empty, mop wash, mop dry, water refill, hot-water sterilization, and a built-in fragrance diffuser, up from the S1 Pro’s 10-in-1 station, per T3 and Android Headlines.
- 68 days — how long eufy says the dustbin can go between manual empties under normal use.

eufy Omni S2
- 30,000 Pa AeroTurbo 2.0 suction — nearly 4x the outgoing S1 Pro, and independent testing shows it actually cleans carpet better (87% vs 61% embedded-sand removal).
- HydroJet 2.0 self-washing roller mop scrubs at up to 240 RPM and lifts clear of carpet automatically.
- 12-in-1 dock handles nearly everything hands-off — including hot-water mop sterilization and a fragrance diffuser.

30,000 Pa: the suction jump that actually shows up in testing
Spec-sheet suction numbers are easy to inflate and hard to trust — but the Omni S2’s jump from 8,000 Pa to 30,000 Pa isn’t just a bigger number on paper. VacuumWars and Gear Live’s comparative testing found the Omni S2 pulled 87% of embedded sand out of carpet versus the S1 Pro’s 61%, and put up 88%+ pet-hair lift on carpet as well. That’s the difference a real motor upgrade makes, and it moves the Omni S2 out of “mopping specialist” territory and into genuine competition with high-suction flagships like Roborock’s Saros 20 (36,000 Pa) and Saros 10.
Tom’s Guide’s own independent cleaning tests measured an 89.25% overall score, with pet hair specifically at 84% — strong numbers, though the same review noted the robot struggled with tightly-grouped debris (their Cheerio test) and occasionally scattered clumped cat hair rather than fully collecting it. Real-world performance, in other words, backs up the spec bump without being flawless.

HydroJet 2.0: the roller mop, tuned up
The Omni S2 keeps the self-washing roller concept the S1 Pro pioneered, but tunes it up: HydroJet 2.0 applies about 15N of downward pressure at up to 240 RPM, per VacuumWars, versus the S1 Pro’s roughly 1 kg (about 10N) at 170 RPM. The roller still rinses itself with clean water mid-run rather than dragging a dirtying pad, and it lifts about 2 inches automatically to keep carpet dry as it crosses. T3 called the mopping performance “brilliant” in testing.
The dock backs it up: a 12-in-1 UniClean-style station adds electrolyzed hot-water sterilization and a fragrance diffuser on top of the S1 Pro’s self-empty, wash, dry, and water-refill functions — genuinely new capability, not just a repackaged 10-in-1 dock, per T3 and Android Headlines.
Where it falls short: navigation
Two independent reviewers landed on the same conclusion. Tom’s Guide’s review was literally titled “excels in just about everything except this one thing” — that one thing being navigation, despite the new CleanMind AI system combining 3D mapping with RGB camera vision and recognition of 200+ object types, per Android Authority. T3 separately called navigation “short of top rivals” in its own testing, and both outlets flagged the Omni S2’s high price and eufy’s proprietary mop-pad/accessory ecosystem as secondary downsides.
Neither reviewer called navigation bad — it’s a flagship-tier robot that maps and avoids obstacles competently. The critique is relative: at $1,599.99, buyers are comparing against best-in-class mapping from rivals, and the Omni S2’s camera-and-AI system, while genuinely upgraded from the S1 Pro’s binocular infrared setup, doesn’t quite close that gap.
eufy Omni S2 vs eufy S1 Pro vs Roborock Saros 20
| Omni S2 | S1 Pro | Saros 20 | |
|---|---|---|---|
| Suction | 30,000 Pa | 8,000 Pa | 36,000 Pa |
| Mop | HydroJet 2.0 roller, 15N/240 RPM | HydroJet roller, ~10N/170 RPM | Dual spinning pads |
| Navigation | CleanMind AI (camera + mapping) | 3D MatrixEye binocular IR | LiDAR + AI camera |
| Dock | 12-in-1, hot-water sterilize, fragrance | 10-in-1, ozone water | Multi-function dock |
| Price | $1,599.99 | ~$700–$900 clearance | $1,599.99 list |
| Known weak spot | Navigation (per Tom's Guide, T3) | Carpet suction (2024-era) | Price |
| Best for | Suction + mop, all-in-one | Max scrub per dollar | Raw carpet suction |
At the same $1,599.99 price point as the Roborock Saros 20, the choice comes down to priorities: the Saros 20 edges ahead on raw suction and LiDAR-based mapping, while the Omni S2 counters with a superior self-washing roller mop and a more elaborate dock. If your S1 Pro is aging out, our full eufy S1 Pro review has the clearance-price case for staying one generation behind. For the wider brand match-up, see eufy vs Roborock.
Who should buy the eufy Omni S2
- Buy it if you want eufy’s roller-mop concept with genuinely flagship suction — the 30,000 Pa jump shows up in real carpet-cleaning tests, not just the spec sheet.
- Buy it if hands-off maintenance matters — a 12-in-1 dock with hot-water mop sterilization and a ~68-day dustbin interval is about as low-touch as robot vacuums get in 2026.
- Buy it if you’re comparing self-washing roller mops against spinning-pad flagships like the eufy X10 Pro Omni — the Omni S2 out-scrubs disc-pad designs.
- Skip it if best-in-class mapping and obstacle avoidance is your top priority — Tom’s Guide and T3 both independently found navigation the weakest link here.
- Skip it if $1,599.99 is a stretch — the discontinued eufy S1 Pro uses the same core mopping idea for roughly half the price, if 8,000 Pa suction is enough for your floors.
The bottom line
The eufy Omni S2 makes good on its headline spec: 30,000 Pa isn’t a marketing number, it’s a measured 87% embedded-sand removal on carpet versus its predecessor’s 61%, per independent testing. Layer on a genuinely improved self-washing roller mop and a 12-in-1 dock that handles nearly everything short of restocking cleaning solution, and you have one of 2026’s strongest all-around flagships — Tom’s Guide’s 89.25% overall score backs that up. The one real caveat, flagged independently by two outlets, is navigation: competent, upgraded from the S1 Pro, but not class-leading at this price. If mapping polish isn’t your dealbreaker, the Omni S2 earns its $1,599.99 price tag.
