Owner Insightssummarized from Reddit and owner forums
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 Reddit reports.
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 Reddit 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.
What owners like
- +Perfect 24-of-24 obstacle-avoidance score in Vacuum Wars testing — it simply does not hit things
- +Massive carpet improvement over the S1 Pro — 87% deep clean vs 61% — with 0% hair tangles from the DuoSpiral split brush
- +12-in-1 UniClean dock goes about 68 days between debris empties and auto-dispenses detergent
- +HydroJet roller mop self-cleans as it mops, presses at 15N, and lifts a full 28mm over carpet — one of the highest lifts in class
- +Built-in scent diffuser with three fragrances sounds like a gimmick, but reviewers consistently note the house actually smells freshly cleaned
Common complaints
- −Mopping regressed from the S1: an 82-point dried-stain score, about 20% below the studio average, because it meters water too conservatively (0.35g vs a 1.07g average)
- −$1,599.99, and it keeps you inside eufy's ecosystem for detergent and fragrance refills
- −Noticeably louder than competing flagships while vacuuming
- −Slow, below-average navigation — roughly 1,088 sq ft per charge and unhurried runs
- −Failed a 32mm threshold in testing despite its 35mm climbing rating
- −Several Reddit owners returned it and bought the ~$600 Ecovacs T90 Pro Omni instead, citing value and easier upkeep
