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

Colin Angle, co-founder of iRobot, recounts the company's journey from a robotics lab with no clear business model to creating the iconic Roomba vacuum. The story covers the early struggles for survival, the unexpected marketing breakthrough that saved the product, and the eventual challenges from global competition and a failed acquisition by Amazon.
iRobot began in 1990 with government contracts, building everything from bomb-disposing robots to AI-powered dolls. The Roomba was born from a quick prototype and a key insight: people would pay for a vacuum, not a mop. After a slow start, a Pepsi commercial featuring Dave Chappelle tripled sales overnight. A subsequent product failure was turned into a loyalty win through free replacements. Despite the Roomba's success, iRobot struggled to diversify and faced declining market share due to tariffs and Chinese competition. A $1.7 billion acquisition by Amazon was blocked by regulators, leading to the sale of iRobot's technology to a Chinese firm. Angle has since started a new consumer robotics company, reflecting on the balance of hard work and luck in entrepreneurship.
