Most robot vacuum launches focus on a single headline spec. The Omni S2 is throwing the entire feature list at the wall. There's class-leading suction, a self-cleaning rolling mop, AI obstacle avoidance, electrolyzed water disinfection, and, in what might be a first for the category, a built-in aromatherapy system that scents your home while the robot cleans it.
The S2 made its debut at CES 2026, picking up a Best of Innovation award, and is now available on Eufy.com and Amazon.
30,000 Pa of Suction That Actually Lasts
The suction system here is called AeroTurbo Carpet Master, and it delivers 30,000 Pa and 100 air watts, a figure Eufy claims is up to 5 times stronger than competing units. What's arguably more interesting is the claim that it holds peak suction for weeks rather than degrading as the filter fills up.
That staying power comes from cyclone separation technology that directs dirt away from the filter, keeping it clog-free for up to 90 days. For carpets specifically, the S2 handles pile heights up to 5cm and can cross thresholds up to 35mm. The DuoSpiral detangling brushes are designed to handle hair without jamming.
HydroJet Mopping That Cleans Itself
The HydroJet Always Clean Mop is an 11.4-inch rolling mop that self-cleans 360 times per minute by scraping dirty water off the floor surface. Downward pressure sits at 15N, which is meaningfully more force than most competing mop systems, and the robot carries separate clean and dirty water reservoirs, so it isn't redistributing contaminated water.
The electrolyzed water feature is the standout: the station converts tap water into a hypochlorous acid and ozone solution that Eufy says kills 99.99 percent of common household bacteria. It's the kind of claim that sounds marketing-heavy but is backed by real science.
CleanMind AI: 200+ Obstacles, 40+ Stain Types
Navigation runs on a 3D ToF and RGB camera system that recognizes over 200 types of household obstacles, including cables, shoes, toys, and tassels on rugs. The tassel avoidance is a nice detail, and it's a known failure point for robot vacuums that few brands specifically address.
Dirt identification covers over 40 stain types, and the system adjusts water flow, mop pressure, and scrubbing duration based on what it detects. The S2 also builds a 3D map of your home in the app, recognizing rooms, floor types, and furniture placement. Matter support means it slots into most major smart home ecosystems without friction.
The 12-in-1 UniClean Station
The station handles self-emptying, self-refilling, hot-water mop washing, hot-air drying, wastewater collection, and automatic detergent dispensing. The 3L dust bin, 2.5L clean water tank, and 1.8L dirty water tank are all managed from the station, which has LCD controls and a dirt detection system.
Then there's the aromatherapy. Available scents include Citrus and Basil, Bamboo and Sage, and Bergamot and Lychee, released during each cleaning cycle. Whether you want your robot vacuum doubling as a diffuser is entirely a personal preference call, but the option is at least easily ignorable if it's not your thing.
Pricing and Availability
The Omni S2 is available now on Eufy.com and Amazon for $1,599/£1,599.
At this price point, the S2 is competing against the top-tier Roborock and Narwal flagships. The combination of electrolyzed water disinfection, long-lasting suction, and a self-managing station ticks the same boxes as those units. The aromatherapy feature is genuinely novel, if a touch eccentric. What remains to be seen in hands-on use is whether the 30,000 Pa claim holds up across real-world floor types and whether the mopping system actually eliminates the streaking that plagues most robot mop competitors.
