The Ecovacs Winbot W2 Omni is primarily designed for cleaning vertical windows and not for horizontal or almost horizontal surfaces such as the ceiling of a conservatory.

- The Winbot W2 Omni uses a suction function to suck up to and clean vertical glass surfaces. However, it is not suitable for cleaning horizontal or almost horizontal surfaces as it has no mechanisms to adhere to or navigate on such surfaces.

- There are currently no specific window cleaning robots from Ecovacs or other manufacturers that are specifically designed to clean near-horizontal glass from below. For such applications, a hand-held cleaner or other type of cleaning technology may be more suitable.
