EcoVacs Winbot 850 window cleaning machine features

Smart Path Edge Technology

The EcoVacs Winbot 850 automatically identifies your window size and shape. Then, it maps a systematic path to clean with greater efficiency.

Deep Clean Mode

The EcoVacs Winbot 850 automatic window cleaning system uses a 4 stage cleaning process that then squeegees and wipes the glass in all directions. While it navigates, the automated patterns polish to leave your windows sparkling and streak-free.

Extra Safety Systems

Several safety systems keep your EcoVacs Winbot 850 running smoothly. The Safety Tether System is an industrial strength suction cup plus a cored-based device. Therefore, it is perfect for both indoors and outdoors.

Power Suction

Advanced suction technology maintains a safe attachment to the glass. In addition, extra powerful suction gives firmer wiping actions for cleaning cloths. Above all, it makes your windows even cleaner.

Edge Detection

Edge Detection technology reacts with a touch of the frame, or near the edge of frameless windows. As a result, it changes direction.

Automatic Path and Memory

Winbot 850 uses an N-shaped path for taller, vertical windows and a Z-shaped cleaning route for wider, horizontal windows. This automatic cleaning choice cleans thoroughly and efficiently, every time.

Above all, the EcoVacs Winbot 850 is an excellent choice to keep your windows sparkling clean, inside and out.
