Briefly

The Winbot W2 Omni not only cleans glass surfaces seamlessly without smearing but also navigates effectively, ensuring a thorough cleaning of windows both inside and out.
Ecovacs has made significant advancements in window-cleaning robots since 2011, creating a product that turns window cleaning into an enjoyable task rather than a chore.
