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.
- Not ready to buy? eufy also rents the Omni S2 through its Flex program at $55/month — see our robot vacuum rental guide for the breakeven math against the $1,599.99 purchase price.
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.
