iRobot: Colin Angle. How The Roomba Became a Household Icon

Colin Angle didn’t start out trying to clean people’s floors. He started out trying to shape the future–with robots. In the early days of iRobot, there was no business model. No steady funding. No clear customer. Just a belief that robotic technology would one day make the world a better place. In the early days, the company built babbling toy dolls for Hasbro, and roving bomb-detectors for the military. But for more than a decade… nothing truly took off. Until one idea—a robot vacuum—finally did. With the Roomba, iRobot created a category from scratch, and a product that felt almost like a member of the family. Tens of millions of units sold, and the Roomba became part of popular culture. But to avoid stagnation, iRobot had to sell to a bigger company. When a lucrative deal with Amazon fell through, the company hit a wall–and never recovered. This is a story about building a business in survival mode, creating a household icon, and eventually getting bested by forces beyond your control.
