Eufy Omni S2

The Omni S2 is Anker's flagship swing at the premium tier, and its signature stat is one nothing else in this catalog matches: a perfect 24-of-24 obstacle-avoidance run in Vacuum Wars testing. Reviewers describe a robot you genuinely don't supervise — T3 called it "a brilliant all-round solution" needing little in the way of babysitting. It also fixes the S1 Pro's biggest flaw, jumping from 61% to 87% on carpet deep cleaning with zero hair tangling. Note that this is a 2026 release with thin owner-thread coverage so far — most of what's below comes from professional long-term reviews rather than a deep well of owner discussions report.

The daily experience is built around the 12-in-1 UniClean dock: heated 140°F mop washing, hot-air drying, auto-detergent, a claimed 68 days between debris empties, and a scent diffuser (Bamboo & Sage, Citrus & Basil, or Bergamot & Lychee) that reviewers admit actually works. The HydroJet roller mop cleans itself as it goes, extends toward walls, and lifts 28mm over carpet. The catch is the mopping result itself: it dispenses so little water (0.35g vs a 1.07g average in testing) that dried-stain removal came in about 20% below average — a step back from the S1. It's also slower than average around the house, louder than rivals while vacuuming, and it flunked a 32mm threshold despite its 35mm rating.

This is for mixed carpet-and-hard-floor homes with clutter, kids' toys, and pets — the households where obstacle avoidance is worth more than scrubbing power. At $1,599.99 it sits right at Roborock Saros 20 money with weaker mopping and no comparable threshold climbing, which is a hard sell at list; the most damning data point is owners returning it for the half-price Ecovacs T90 Pro Omni. Catch it on one of eufy's frequent $200+ coupon deals and the calculus improves considerably.
