Clever, But It's a Job That's Going Away

If you thought that washing windows on upper floors required scaffolding or at least a ladder, you would be mistaken.

These fellows have implemented a safer, cheaper method that doesn't need advanced technology.

I imagine that drones will soon be doing this job. They can "see" dirt that is missed from a distance and can apply precise pressure to stubborn spots.

They can service much taller buildings and their arms don't get tired.
