iRobot: Colin Angle. How The Roomba Became a Household Icon
Colin Angle, co-founder of iRobot, discusses building the company from a 1990 MIT robotics lab into the creator of the iconic Roomba vacuum robot. After years of military and research contracts, the Roomba's 2002 launch transformed consumer robotics, but the company was eventually sold to a Chinese firm after a blocked Amazon acquisition.
Summary
Colin Angle started iRobot in 1990 with MIT professor Rodney Brooks and Helen Grainer, beginning as a research-focused robotics company surviving on government and corporate contracts for eight years before taking venture capital. The company built robots for various applications, including the life-saving PACBOT for military bomb disposal in Afghanistan and Iraq, and consumer toys for Hasbro like My Real Baby. The breakthrough came with Roomba in 2002, initially launched through Brookstone after Sharper Image backed out. Early sales were strong with 70,000 units in three months, but 2003 saw a major slump until a Dave Chappelle Pepsi commercial unexpectedly revived demand, leading to 250,000 sales in six weeks. The company went public in 2005 and eventually sold 30 million Roombas worldwide, peaking at $1.5 billion revenue in 2021. However, rising Chinese competition, supply chain issues, and tariffs created challenges. Amazon's $1.7 billion acquisition offer in 2022 was ultimately blocked by regulatory authorities, forcing iRobot to eventually sell to a Chinese company. Angle stepped down after 34 years and is now working on a new stealth-mode robotics company focused on generative AI-controlled robots.

Key Insights
- Angle argues that robotics should be viewed as a toolkit for solving problems rather than just humanoid machines
- The company survived for eight years without venture capital by taking government and corporate contracts while developing their core technology
- Angle claims that early consumer research showed people would pay hundreds of dollars for a robot vacuum but only $40-50 for a floor-dragging robot
- The company discovered that systematic navigation and customer control were essential for moving beyond early adopters to mainstream consumers
- Angle contends that a Dave Chappelle Pepsi commercial in 2003 saved the company by generating 250,000 sales in six weeks after a major inventory crisis
- The founders learned that replacing themselves in technical roles and delegating to better-skilled employees was crucial for scaling the business
- Angle argues that investing heavily in customer service for defective products generated more loyalty than if customers never experienced problems
- The company found that demonstration was key to sales success, with Brookstone using working floor demos to draw mall traffic
- Angle claims the FTC blocking Amazon's acquisition effectively handed iRobot's technology to Chinese competitors rather than protecting consumers
- The company discovered early that people consistently asked for robot vacuum cleaners from day one, even when they were focused on other applications
- Angle argues that the perfect autonomous robot concept initially failed because consumers wanted control and communication rather than invisible operation
- The military PACBOT robots saved lives by replacing soldiers in dangerous bomb disposal situations, with some robots marked by soldiers tracking successful IED removals

Certainly the dream was, let's be honest, we were promised robots. We humans were promised robots. Yes, we were going to build robots. And everyone asked for a robot vacuum cleaner from the very first day. Wait, when you would meet people, they'd say, oh, when is Rosie, like from the Jetsons? Going to be in my house. When are you going to clean my floor? Welcome to How I Built This, a show about innovators, entrepreneurs, idealists, and the stories behind the movements they built. I'm Guy Raz, and on the show today, how Colin Engel set out to make robots part of our daily lives and brought us What I Built. One of the most iconic home helpers…
