A Wired reviewer tested the premium Ecovacs Winbot W2S Omni window-cleaning robot and came away disillusioned with the entire product category, despite the device performing reasonably well on large, modern windows. While the robot's design impressed on straightforward glass surfaces, it struggled badly with more traditional window styles, leading the reviewer to conclude that robotic window cleaners are not worthwhile for most homes.

The Winbot performed decently on a large 7×10-foot modern window, cleaning efficiently via suction and tank-style tracks, though it left residue in corners and some smearing. It also required frequent pad changes and refilling of cleaning solution after just a window and a door, and struggled with obstacles like a door handle. The device fared far worse on the reviewer's Victorian-style sash-and-case bay windows, where it got stuck attempting to clean the largest pane. The reviewer noted the Ecovacs (around $449–$600) outperformed the cheaper Mova N1 ($199) in efficiency and design, but still judged the category unsuitable for typical homes with varied window types.
