Window-washer won't scratch your panes

We got our first look at Ilshim Global's Windoro window-washing droid at CES, and it didn't seem to leave a scratch on the demonstration glass.

Equipped with an accelerometer and bumper sensors, Windoro has two magnetically linked halves that clean one side of the glass at a time with detergent and microfiber pads.

It has attracted a lot of attention as the first product of its kind, but setting Windoro up is a multistep process that seems to make it more of a chore than a convenience.
