They work for maintenance, not for deep cleaning. That's the consistent finding across published reviews. Hub: [window robots](/ai-life/home/window-robots/).

## What reviewers found

- **Ecovacs Winbot W2 Omni and W2 Pro Omni** clean dust, fingerprints, water marks and moderately dirty glass well. TechRadar's reviewer said the W2 Pro Omni got filthy windows clean ([TechRadar](https://www.techradar.com/home/smart-home/ecovacs-winbot-w2-pro-omni-review)). How-To Geek called the W2 Omni weird and wonderful ([How-To Geek](https://www.howtogeek.com/ecovacs-winbot-w2-omni-review/)). Corners and stubborn grime may still need a wipe. {{< aff ecovacs "See the Winbot W2 at Ecovacs" />}}
- **Hobot** models cost less. Choice tested the Hobot R3 and asked whether an $800 window robot does a good job ([Choice](https://www.choice.com.au/home-and-living/laundry-and-cleaning/vacuum-cleaners/articles/hobot-r3-robot-window-cleaner)). TechRadar found the S7 Pro a big help on big windows ([TechRadar](https://www.techradar.com/home/small-appliances/hobot-s7-pro-window-cleaning-robot-review)).

## Where they help

- Large, frameless panes like sliding doors.
- Windows that are hard to reach from inside.
- Regular light cleaning, so dirt never builds up.

## Where they don't

- You still attach the robot, watch it and move it pane to pane.
- Textured glass, gaps and very dirty surfaces are a poor fit.
- Corners need a cloth.

## Verdict

If you have a wall of glass and want it clear between proper cleans, they're useful. If you have many small framed windows, a squeegee is faster. The same "maintenance, not miracle" logic applies to [robot vacuums with mop docks](/ai-life/home/robot-vacuums/self-emptying-mop-dock-worth-it/).
