eufy Robot Vacuum Omni S1 Pro: Specs, Features, Pros & Cons
eufy's Omni S1 Pro mops with a roller that eufy calls always-clean, and the station behind it takes on ten jobs by eufy's count. Between them, the robot and its base aim to keep a long mopping run going without the mop turning grubby halfway through.
The roller lifts clear when carpet appears, and the station washes it and doses detergent without prompting, so there is nothing to measure out by hand. The roller also comes out of the robot for replacement.
The endurance is the surprise in the spec sheet. It comes from a 4,600 mAh battery, a modest capacity, yet eufy rates one charge at well over three hours. LiDAR handles navigation, with mapping and no-go zones, 3D obstacle avoidance steers round clutter, and recharge-and-resume picks up an unfinished job.
Suction trails the flagships, there is no extending arm to reach into corners, and the list of cleaning modes is short. The robot mops and vacuums in one pass, but carpets and pet hair get less attention than on a higher-powered machine.
eufy says the roller is rinsed with clean water as it turns, the meaning of its always-clean label, and the robot climbs thresholds of up to 20 mm. The long runtime pays off on hard floors in a large home, because one charge covers what a shorter-running robot splits across two. The roller is the change a spinning-pad owner will notice first.

How this VS Score was computed
Score 47: each known spec is measured against the median of all robot vacuums (58 products), then weighted; 50 means level with that median. In classes of six or more, a value beyond the class’s 10th–90th percentile range counts as that limit, so one extreme product cannot set the scale. 47% of the scoreable weight could be used; unknown values, features not applicable to this class and proxies (battery capacity where a rated life exists) add or remove nothing.

Editor’s note
The Omni S1 Pro runs for 216 minutes in standard mode and 277 in quiet mode, and it does it at under 60 dB.
Both figures are eufy's ratings for those modes, and eufy does not publish the floor or settings behind them. The standard-mode runtime is the one to plan around. How much floor one charge covers depends on carpet, boost and mopping, so a long rating does not mean a large home gets done in one pass. The quiet mode is what lets it run while you are in the house.
The mop is a roller in place of spinning pads, applying continuous pressure across its width and presenting a clean surface as it turns, which handles dried marks better than a dragged pad. It lifts 12 mm for carpet, the dock washes it and dispenses detergent automatically, and the roller comes out for replacement.
Navigation is LiDAR with obstacle avoidance and mapping, so it works as well at night as during the day. At 96 mm it clears more furniture than the 105 mm machines, and the water tank holds 240 ml with a 250 ml bin.
Suction is rated at 8,000 Pa, under half of what current roller-mop flagships from ECOVACS and Roborock list. Each maker measures Pa its own way, so that gap is a difference between listings and says nothing measured about cleaning. Taken as a rating, it suits hard floors and low-pile carpet, and deep rugs ask for more.
eufy stopped selling it on its US store in April 2026, so the warranty from whichever retailer still has stock counts for more than it would on a current model.

The bottom line
The eufy Robot Vacuum Omni S1 Pro earns a VS Score of 47, below the median of the 58 robot vacuums it is measured against (a score of 50 is level with that median).
- Who it’s for
- Large, mostly hard-floored homes where the robot runs while people are in, and one long quiet pass matters more than power.
- Who should look elsewhere
- Carpet-heavy homes and pet owners fighting hair should look elsewhere, and so should anyone who wants corners reached by an extending arm.
- The trade-off that matters
- Suction is where it falls short. Hard floors and low pile are fine, and deep rugs or shed fur get a lighter clean than a flagship motor gives.
- The main alternative
- Roborock Qrevo Curv 2 Flow: also a roller mop, still on sale, with far more suction and a dock that washes the roller hot.
