New $600 Robot Efficiently Cleans Windows Indoors and Out, But Has Some Drawbacks

The Winbot W2 Omni is a $600 window cleaning robot that works indoors and outdoors, cleaning windows seamlessly without smearing
It comes with a portable charging station and can clean 592 sq ft of windows on a single charge
The robot efficiently cleaned even very dirty windows like a sliding glass door in one pass
Downsides are that it doesn't work while plugged in and could alert you louder when finished
Overall the Winbot makes window cleaning much easier and cheaper compared to doing it manually
