Well it looks like window cleaners days are numbered, with the invention of a window cleaning robot from four engineering students from Michigan State University.

This fun robot called the Winboni runs of 4 AA batteries and sticks to the window using a suction fan, it then uses felt pads to clean the window.

The team from Michigan state university which included Emily Duszynski, Kyle Koepf, Joshua Thomet and Jonathon Luckhardt won first prize in the International Student Design Competition of the American Society of Mechanical Engineers.
