No one hates washing windows more than me--except the pros who teeter on scaffolds to keep the floor-to-ceiling windows of skyscrapers sparkling clean. To address this sore need, four Michigan State University students designed the Winboni, a tiny robot that attaches to a window with a suction fan and cleans autonomously.

The Winboni is powered by two AA batteries, and the diminutive prototype took first place last month at the International Student Design Competition of the American Society of Mechanical Engineers.

The Winboni's design team is comprised of Emily Duszynski, Kyle Koepf, Jonathan Luckhardt, and Joshua Thomet.
