Eufy Omni S2: Robovac with a roller mop exceeds clean (review)
Summary
The Eufy Omni S2 is a major step forward for robot vacuum/mops, building on the S1 Pro’s roller-mop concept and improving suction, mopping delivery and AI-driven navigation. Key hardware upgrades include 30,000 Pascals suction, an on-board cyclonic dustbin, HydroJet 2.0 roller-mop with ozonated water delivery, the tangle-free DuoSpiral brush and a compact UniClean station that washes and dries the roller. Across four panellists’ homes the Omni S2 delivered near-perfect hard-floor mopping (97–98% first pass), very strong pet-hair pickup and above-average carpet performance, though heavy high-pile patches can require extra pauses or a second pass.
The robot excels at obstacle avoidance, maps quickly (approx. 1 minute per 10m2), supports multi-level maps, and applies AI to choose cleaning strategies and detect 40+ mess types (including liquids and pet waste). Australian RRP is AUD 2,499 with expected retail availability in October (pre-production firmware tested). Overall verdict: almost perfect for whole-of-home unattended cleaning, especially if mopping is a priority.
Key Points
- Roller-mop system (HydroJet 2.0) uses ozonated water and continuous self-cleaning to avoid dragging dirty water across floors.
- 30,000 Pascals suction and an on-board cyclonic dustbin maintain consistent suction as the bin fills.
- DuoSpiral rotary brush is tangle-resistant and effective on pet hair and many carpets.
- Strong AI suite with RGBD cameras, dToF LiDAR and 3D MatrixEye 2.0 for exceptional obstacle avoidance and room-aware cleaning.
- Exceptional hard-floor mopping: ~97–98% first-pass cleanliness in tests.
- Very good vacuuming on short and medium pile; high-pile carpets may need extra duty cycles.
- Compact UniClean station washes, soaks and hot-air dries the roller; smaller footprint than many competitor docks.
- Good battery endurance (up to ~150 minutes), fast mapping and multi-map support for multi-level homes.
- Pet-focused features: pet mode, liquid detection and steering clear of messes; performs well on faux pet poo tests.
- Australian RRP AUD 2,499; one-year warranty (ACL applies).
Why should I read this?
If you care about clean floors without babysitting your robot, this review cuts to the chase. We’ve actually run the Omni S2 in four real homes and it pretty much rewrites the rulebook for robot mopping — less dragging of dirty pads, smarter obstacle handling and proper suction. If you hate streaky floors or pets that leave surprises, this one might save you a lot of elbow grease.
Author style
Punchy: This isn’t incremental tinkering — Eufy has pushed roller-mop tech and practical AI into a package that feels like a genuine generational leap. If you’re in the market for a premium robovac this year, the details here matter: suction, mop delivery, obstacle behaviour and how the UniClean station actually works day-to-day. Read the specifics before you buy.
Context and relevance
The Omni S2 arrives as the roller-mop trend becomes mainstream. It tightens the gap between proof-of-concept designs and genuinely usable whole-home solutions. Its AI-driven mapping and object recognition put it squarely in the Gen 5 class of robots capable of unattended cleaning across multiple levels. Competitors such as Ecovacs, Narwal and Dreame are bringing similar concepts, but Eufy’s combination of high suction, continuous roller cleaning and a compact dock gives it a distinct edge for hard-floor-first households and pet owners.
Quick verdict
Pros: Outstanding hard-floor mopping, strong pet-hair performance, superb obstacle avoidance, compact cleaning station, fast mapping and convincing AI-driven automation. Cons: High-pile carpets may require extra cycles; one-year warranty is conservative for a premium product.
