A good pick for people with large panes who want a station that holds the battery and reels in the cable. Teltarif found it cleaned everyday dirt evenly but left light lines after one pass and dripped on the sill. Skip it for small or barred windows, where it saves little time.

- Yes
The sensible pick for most people who want an Ecovacs station model, since it keeps the battery station and edge scrubbers of the W3 Omni for $200 less. You rinse the pad yourself instead of letting the station do it. Skip it if you hate manual pad care or only have small windows.

What reviewers found
Ecovacs Winbot W2S Omni
- Teltarif: Cleaned dust and fingerprints evenly; light lines after the first pass shrank on a second pass; some moisture left at edges and drips on the sill. Source
Ecovacs Winbot W2S Pro Omni
- Basic Tutorials (92/100): Navigation needed no intervention and results were nearly streak free; heavy dirt clogged the pad and a second pass helped on soiled glass. Four panes cleaned twice in deep mode took about 10 minutes. Source
