Why I bought it in the first place
My place is a mix of hardwood and carpet, and the hardwood shows everything — dust, crumbs, the works. I'd tried the cheaper-robot-vacuum route before and always ended up finishing the job by hand, especially the mopping. So when eufy put a self-cleaning roller mop and a fully automatic dock into one machine with the Omni S2, I decided to find out whether spending flagship money actually buys you back your weekends.
What you actually get for $1,599
The Omni S2 is eufy's 2026 flagship, and the spec sheet is genuinely top-of-the-class. The numbers that matter in daily life:

Pricing note: $1,599.99 is the U.S. MSRP and the Omni S2 is discounted often. Canadian and regional pricing differs, so check the current price before buying.
Setup and the app
Setup was refreshingly painless. You unbox the robot and station, drop in the supplied cleaning solution and a fragrance pod, and let it run its first mapping pass — the app handled my floor plan, oddly shaped rooms and all, without complaint. From there you can set cleaning strategy, water intensity, and suction power per room, plus schedules. It's dependable and easy; if I have a nitpick, it's that the deeper automation and smart-home options are a little thinner than a couple of rival apps, which I'll come back to.
Living with it: hardwood and mopping
This is where the S2 justifies itself. The roller mop is the headline act, and it's the first robot I've owned that leaves hard floors looking mopped rather than just damp. The 15N of downward pressure is the difference-maker: a dried-on coffee ring that older bots would just smear came up in a single pass. Because the roller continuously scrubs and scrapes itself against clean, heated water, it isn't just pushing dirty water around — my hardwood came out consistently streak-free and genuinely shiny.
The mop is the whole reason to buy this thing. It's the first robot vacuum I've used that makes the floors look like I did them myself — except I didn't.
Carpet and hair
On carpet the S2 is smart about itself: it auto-raises its height for pile up to about two inches, cranks the suction, and lifts the mop so it stays dry. Hair — usually a robot vacuum's nemesis — has been a non-issue thanks to the DualSpiral detangle brushes; I've pulled the brush bar out expecting a tangled mess and found it basically clean. The honest caveat: on my thickest, highest-pile carpet it plays it safe and slows right down, and its deep-carpet results aren't a dramatic step up from eufy's much cheaper models. If your home is mostly deep carpet, that's worth weighing.
Navigation and the hands-free dock
Navigation is excellent. The 3D MatrixEye system reliably picks out obstacles — down to roughly centimeter-sized things like a stray charging cable or a dropped sock — and over months of daily runs I can count its actual collisions on zero fingers. The UniClean dock is the other half of the "hands-free" promise and it delivers: it empties the robot, washes and hot-air-dries the mop so it never develops that damp-mop smell, refills clean water, doses detergent, and even runs an electrolyzed-water sterilizing cycle. With a roughly 68-day dust capacity and a filter rated up to a year, I genuinely forget it needs me. The built-in aromatherapy (it ships with three scent pairings) is a gimmick I didn't expect to like and now quietly enjoy.
What could be better
No robot is perfect, and pretending otherwise would make this a worse review. The S2's edge and corner cleaning is its clearest weakness — despite an extending side brush, it still leaves a slim gap right along baseboards and cabinet kickplates that I occasionally touch up by hand. There's also no true one-tap "vacuum first, then mop" cycle: if you want both done properly you set up separate passes, which is a small but real workflow annoyance. Its carpet results, while good, aren't dramatically better than eufy's cheaper models, so deep-carpet homes are paying mostly for the mop and the dock. It's a touch louder than the average flagship (never alarming, just noticeable), and the app's advanced controls and smart-home integration trail the very best competitors. And, of course, the price.
Pros & cons
What I love
- Self-cleaning roller mop tackles dried-on stains in one pass — easily the best mopping I've used
- Enormous 30,000Pa suction and excellent hair detangling
- Genuinely hands-free dock; I go weeks without touching it
- Reliable navigation with effectively zero collisions
What could be better
- Edge and corner cleaning leaves a slim gap along walls and cabinets
- No automatic single-pass vacuum-then-mop; you run separate passes
- Carpet performance isn't a big step up from cheaper eufy models
- A bit louder than rivals; app/smart-home depth lags the best; premium price
eufy Omni S2: frequently asked questions
Is the eufy Omni S2 worth it?
For hard-floor and mixed-floor homes, yes. The self-cleaning roller mop and fully hands-free dock are the best I've used and genuinely cut down floor chores. If your home is mostly deep carpet or you're on a tight budget, a cheaper eufy makes more sense.
eufy Omni S2 vs S1 Pro: what's the difference?
The S2 is the bigger upgrade: roughly four times the suction (30,000Pa), a self-cleaning roller mop with heated water for sticky messes, a tangle-free DuoSpiral brush, and smarter navigation. The S1 Pro is the budget pick if you don't need the latest features.
Is the eufy Omni S2 good on carpet?
It's competent and very good with hair on carpet, and it auto-raises height and lifts the mop to stay dry. But deep-carpet cleaning isn't a dramatic step up from cheaper eufy models, so deep-carpet homes are paying mainly for the mopping and the dock.
Can the eufy Omni S2 vacuum and mop at the same time?
Not in a single automatic cycle. If you want both done properly you set up separate vacuum and mop passes, which is a minor but real workflow annoyance.
How long does the eufy Omni S2 battery last?
Around 120 minutes of runtime, covering roughly 567 to 2,960 sq ft per charge depending on suction mode. It auto-returns to the dock to recharge and then resumes where it left off, so whole-home cleans aren't a problem.
How much maintenance does it need?
Very little. The UniClean dock auto-empties dust for about 68 days, washes and hot-air-dries the mop, and the filter is rated up to 365 days before service. Most weeks you don't touch it.
How much does the eufy Omni S2 cost?
It launched at $1,599.99 USD and is discounted often. Canadian and regional pricing differs, so check the current price before buying.
The verdict
The eufy Omni S2 is the most genuinely low-effort floor cleaner I've owned, and the roller mop alone makes it special on hard floors. If your home is mostly hard or mixed flooring like mine and you want to genuinely stop thinking about your floors, it's worth the splurge. If your home is wall-to-wall thick carpet, you're on a tight budget, or you crave deep smart-home automation, a cheaper eufy or a rival will serve you better. For me — hardwood I actually want mopped, and carpet it keeps tidy between deep cleans — the mopping and the truly hands-off dock made it an easy keeper.
