Automatic 4-Stage Cleaning System

Trade in your old window cleaning tools, WINBOT 850 has them all, minus the elbow grease! The W850 window cleaning robot features a wrap-around microfiber Cleaning Pad and two Squeegees for an efficient 4-Stage Cleaning process:

  • The front of the wrap-around Cleaning Pad sprayed with WINBOT Cleaning Solution moistens, loosens and absorbs dirt.
  • A Squeegee clears dirt from the window.
  • An additional Squeegee swipes any remaining waterborne dirt.
  • The back of the Cleaning Pad wipes the window to a dry, spotless shine.

Automatic Cleaning Path and Memory

Before it starts cleaning, W850 scans the perimeter to detect the shape of the window and automatically adjusts its cleaning path, in order to clean the area in the most efficient way! The window cleaning robot will follow a Z-Shaped Cleaning Path for wide, horizontal windows and a N-Shaped Cleaning Path for tall, vertical windows.

Advanced Fan Technology

WINBOT 850 uses a high-speed fan motor for strong suction, better stability and deep cleaning. At 19.000 rotations per minute, the W850 window cleaning robot stays safely attached to the glass, while cleaning the area thoroughly!
