Quick answer
Buy WINBOT W2S OMNI if you specifically want its newer edge-cleaning system (TruEdge/Quad-Edge with Intelligent Pad Lift), a larger 80 mL water tank, and the roughly C$206 Canadian price premium (checked August 18, 2026) is reasonable for your budget. Buy WINBOT W2 PRO OMNI if you want the better value and don't need the W2S-specific edge improvements — it already has the portable station, WIN-SLAM 4.0 navigation, triple spray and up to 110 minutes of cordless use, identical to W2S on that last point.
ECOVACS now sells both models in Canada at the same time — W2S OMNI didn't replace W2 PRO OMNI, it launched above it. This is a specifications-based comparison, not a hands-on test; all figures below are attributed to ECOVACS Canada's current product pages, verified August 18, 2026.
What's actually new on the W2S OMNI?
Genuinely new: the edge-cleaning system (TruEdge/Quad-Edge with Intelligent Pad Lift replaces W2 PRO's simpler Edge Cleaning mode), the water tank (80 mL vs 60 mL), and stated coverage (~65 m² vs ~55 m² Fast mode). Not changed: cordless runtime (both up to 110 minutes), navigation (both WIN-SLAM 4.0), app modes (both the same 7 modes), safety system (both 12-stage), and frameless-glass compatibility (both list it).

A specification conflict worth flagging
ECOVACS Canada's own W2S OMNI page states two different edge-precision figures in different places: "within 1mm of window edges" in one section, and "full 1.1cm edge-to-edge precision" (11mm) via Quad-Edge Cleaning Mode in another — a full order of magnitude apart. We're flagging this rather than picking the more impressive number.
Is W2S OMNI worth the extra C$206?
At the prices checked August 18, 2026, the gap is C$206. Pay extra for W2S if edge cleanliness near the frame is a real priority and the larger tank meaningfully reduces refills for you. Save money with W2 PRO OMNI if you want the core portable-station experience without paying for the edge upgrade — most first-time buyers without a specific edge-cleaning complaint will get an equivalent core experience for meaningfully less.
Should existing W2 PRO owners upgrade?
Generally no, unless W2S's specific edge-cleaning improvements solve a real, recurring problem with your current unit. A working W2 PRO OMNI doesn't need replacing for incremental gains.
