ECOVACS WINBOT W2S OMNI Crystal: a window-cleaning robot with seven modes

The ECOVACS WINBOT W2S OMNI Crystal is a robotic window cleaner with up to 8,000 Pa of suction, up to 110 minutes of battery operation and seven cleaning modes. It automatically sprays water and, according to the available information, can clean an area of approximately 55 m², making it a potential aid for maintaining larger windows at home or in an office.

Suction and movement on glass

Up to 8,000 Pa of suction helps the robot adhere to vertical glass during cleaning. An anti-slip climbing system helps limit slipping and improve stability as it moves across the surface.

The robot also uses intelligent route planning to guide it across the window while limiting unnecessary repeat passes and missed spots. Results can still vary depending on the conditions and how dirty the glass is.

Follow the manufacturer’s instructions, including any requirements for securing the device, particularly when using it at height. Neither suction nor the anti-slip system guarantees that the robot cannot fall or become stuck.

Automatic water spraying

The WINBOT automatically sprays water onto the glass as it works. Moistening the surface helps loosen dirt, so the user does not have to spray it manually before each pass. The water spray and route planning work together to help clean the window.

Battery life and cleaning area

The model offers up to 110 minutes of battery operation and is intended to clean an area of approximately 55 m². These figures are useful as a guide when considering larger windows or multiple glass surfaces, although actual performance can vary with the conditions of use.

When cleaning several windows, allow time to move the device between surfaces. The battery-life figure alone does not establish whether the robot is connected by a cable to another part of the device during operation.

Seven modes, including manual control

The robot offers seven cleaning modes, including a manual mode. This lets the user adapt its operation to the task and manually direct it over a problem area, for example if visible dirt remains after automatic cleaning.

The modes are intended for different window-cleaning needs, from dust to greasier marks or residue from spilled liquids. Results can vary with the type and amount of dirt, so it is worth checking the glass when cleaning is complete.
