## 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.

### 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](https://basic-tutorials.com/reviews/gadget-reviews/ecovacs-winbot-w2s-pro-omni/)
