The Ecovacs Winbot W2 Omni is not ideal for cleaning ribbed glass or other uneven surfaces such as those in bathrooms or stairwells. Here are some reasons why:

- The robot uses smart climbing technology and WIN-SLAM 4.0 technology designed to recognise and clean smooth surfaces. Rippled glass or uneven surfaces can hinder these technologies and affect cleaning performance.
- It has been mentioned that the robot has problems if there are small gaps or uneven areas, which can lead to a loss of suction power and an interruption in cleaning.

It is therefore advisable to use the Winbot W2 Omni mainly on smooth window surfaces.
