## 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](https://www.teltarif.de/en/fensterputzroboter-testbericht-ecovacs-winbot-w2s/news/100853.html)

### 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/)
