Future Window Cleaning

Here's a good article on the Future of Window Cleaning, from our friends at CleanLink.  It talks about pure water cleaning, ultrasound, cobotics (essentially, extending one's reach), and drones.  

I suspect quick adaption of existing high-rise rigging (when you see a platform hanging on cables from the top of a high-rise, the window crew on the platform washing floor by floor) to facilitate some sort of robotic system to replace the guys on the platform. 

High-rise window cleaning has  always seemed to me to be a major safety risk; I gather that's why workers comp insurance for window cleaning firms is more expensive than for janitorial firms, like mine . We get to stay on solid ground, doing at the moment nothing higher than three stories.  Plus, there's my fear of heights. 

But, we generally include periodic window cleaning, and well as burnishing, refinishing and carpet cleaning, as part of our ongoing service and price.

Be interesting to see how quickly various systems are adopted.
