- Suction

- Spray
- Three nozzle spray
- Backup battery
- 3,000 mAh battery
- Frameless
- Supported
The cheapest way into the W2S line, with the same suction claim and edge scrubber as the Omni. KultureGeek found it cleaned indoor glass well in one pass but noted you manage the cord yourself. Check what is in the box before buying, since Ecovacs US does not list the contents.

- Up to 10,000 Pa
- Spray
- 3 nozzle
- Backup battery
- 110 min cordless
- Frameless
- 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
- KultureGeek (8/10): Tested the version without station: indoor windows came out very clean in one pass, about 2 to 3 min per window, about 65 dB(A) at 1 m; heavy grime needed scraping first. 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
