"How I Built This" with Guy Raz

Episode: iRobot: Colin Angle – How The Roomba Became a Household Icon

Date: April 13, 2026
Guest: Colin Angle, Co-founder and CEO of iRobot

Episode Overview

This episode dives deep into the creation and rise of iRobot, the company behind the iconic Roomba robot vacuum, as told by co-founder and longtime CEO Colin Angle. Guy Raz and Angle explore the inception of iRobot from its MIT research roots, how Roomba pioneered consumer robotics, the challenges of scaling hardware innovation, and the company's unexpected journey through military contracts, toy partnerships, and later acquisition drama. Rich with stories of personal struggle, delightfully nerdy innovation, and hard business lessons, the episode also reckons with the recent end of iRobot’s independence and Angle's forward-looking optimism.

Key Themes and Discussion Points

1. Childhood Roots of Curiosity and Engineering (05:11-06:16)

• Colin’s Early Obsession with Building:
  Angle shares anecdotal stories from childhood, such as engineering a "gantry crane" to transport his milk glass—revealing a lifelong passion for invention.

  “I would embark on a two day long project to create a gantry crane to automatically lift that glass of milk and carry it on cables into the kitchen and really shut down the house for a few days.” (Colin Angle, 05:11)

• Striking a Balance:
  Emphasizes his dual identity as both a "smart jock" and a hands-on creator.

2. The Path to MIT and Early Robotics (06:16-10:51)

• Serendipitous Start:
  Angle recounts how a chance walk led him to apply at MIT's legendary robotics lab under Rodney Brooks.

  "I'm at MIT and everyone is already done writing down the stuff that they have built, and I'm not done yet...and I got this job." (Colin Angle, 07:25)

• Defining Robots as Toolkits, Not Humanoids:
  Angle’s first assignment (getting a robot to open doors) led him to realize the flexibility and creativity of robotics as a “toolkit,” not just humanoid machines.

  "Robotics was a box of parts that allowed you to make smart machines that were capable of doing interesting things..." (Colin Angle, 08:52)

3. Founding iRobot: No Business Model, Just Belief (11:15-14:44)

• Bootstrapping and Contract Research:
  iRobot was born from academic ambition but had no consumer focus; early revenue came from selling robots to companies like Mitsubishi for research, with most years spent living “hand to mouth.”

  "Six and a half years before I started a month with enough money in the bank to make payroll." (Colin Angle, 13:47)

• Engineering Culture over Business Sense:
  The team respected technology, not marketing—Angle jokes about marketing being seen as “marketing weenie.”

  "You weren't allowed to say marketing without saying weenie, you know, immediately afterwards." (Colin Angle, 17:07)

4. Unexpected Lessons from Toys and Military Robots (21:00-29:48)

• Learning from Hasbro:
  Building the interactive toy "My Real Baby" taught iRobot about low-cost manufacturing and consumer production—even if it was slightly creepy.

  "We learned how to make low cost robots...That's where we learned how to make consumer products." (Colin Angle, 23:13)

• Military Success with Packbot:
  Packbot was used in Afghanistan and Iraq to safely inspect/disarm bombs. The robots became beloved by soldiers.

  "We would get postcards from the soldiers saying, you have saved lives today. It was very moving..." (Colin Angle, 29:49)

5. Roomba: From Joke to Phenomenon (31:25-42:19)

• The Breakthrough Product:
  Roomba's origins stemmed from a prototype that dragged a Swiffer cloth, but consumer research revealed only a true vacuum would hold value.

  "If it was a vacuum, then I'd pay hundreds of dollars for it. And it was like, okay, time to make a vacuum." (Colin Angle, 33:34)

• Technical Innovation – The “Squeegee Vac”:
  The Roomba’s two-stage cleaning system took inspiration from battery limitations and engineering constraints.

• Retail "Hacking" and Viral Growth:
  Early sales came from direct retail demos at Brookstone, with Angle using crushed Cheerios to showcase the device’s prowess.

  “I would stomp and crush and try to grind the Cheerios into the rug, at which point I had their complete attention because I just messed up their conference room.” (Colin Angle, 36:45)

• Press Coverage & The Cat on Roomba Effect:
  Massive media attention and viral user videos followed:

  “We had 150 articles written about the Roomba immediately after launch...” (Colin Angle, 39:06)

• Early Marketing Mistakes:
  Failure of their first TV commercial, made “by engineers for engineers,” leading to a reliance on word-of-mouth.

6. Unlikely Lifeline: The Dave Chappelle Pepsi Ad (43:12-45:48)

• Sales Miracle:
  A surprise appearance in a popular Pepsi commercial featuring Dave Chappelle revived flagging sales, moving a quarter-million units in six weeks.

  “Pepsi had made a commercial with Dave Chappelle...and the Roomba locks onto the Pepsi and starts chasing Dave to try to get the Pepsi...We sold 250,000 Roombas in six weeks after that ad.” (Colin Angle, 44:23)

7. Brand Loyalty, Growing Pains, and Going Public (45:54-47:50)

• Standing by Customers:
  Early units wore out too quickly. iRobot replaced broken Roombas for free, which built intense customer loyalty.

  “If a company stands behind its product, you generate more customer loyalty than if that customer never had a problem with their product at all.” (Colin Angle, 46:31)

• IPO and Scaling:
  Rapid success led to a public offering (IPO) and large-scale global sales.

8. Plateau, Competition & The Need to Evolve (47:50-54:53)

• Reaching Mainstream Consumers:
  The "invisible robot" concept didn’t resonate as tech fatigue set in; consumers wanted more agency and confidence.

  “The customer wanted confidence that they could control where the Roomba cleaned and the Roomba would be safe...” (Colin Angle, 49:50)

• Product Diversification—Success and Failure:
  iRobot’s attempts at a mopping robot (Scuba) and lawn mowing robot (Terra) didn’t take off, but their experience shaped the company’s shift toward smart home integration.

9. The Amazon Acquisition Saga and Regulatory Roadblocks (53:50-59:17)

• Market Disruption:
  U.S.-China tariffs, Covid, supply chain chaos, and low-cost overseas competition battered iRobot.

  "We were spending $22 on a half a cent resistor so that we could actually build a Roomba." (Colin Angle, 54:35)

• The Amazon Deal & Its Collapse:
  Amazon’s $1.7 billion buyout bid would have boosted global reach and smart-home synergy, but U.S. and EU regulators blocked the deal.

  "We made the decision when it was clear that the European Commission and the FTC were blocking this deal. And the FTC blocked this deal knowing that they were effectively putting iRobot in a box and handing it to somebody else." (Colin Angle, 56:54)

  "The biggest loser was the hundreds of products, innovative products that could have come out as a result of this merger." (Colin Angle, 58:57)

• Aftermath:
  iRobot was ultimately sold to a Chinese competitor, transferring dozens of patents and extensive know-how overseas—“We used to, past tense, lead ... China does.” (Colin Angle, 59:17)

10. Looking Ahead: Reinvention and Optimism (60:39-63:13)

• Onward to New Projects:
  Angle is already working in stealth mode on a new robotics venture, leveraging generative AI.

  “Absolutely. It is in robotics, it's in consumer robots. It's taking advantage of this amazing new toolkit, generative AI, and using these generative tools to control robots. Because I'm still who I am. I'm still this builder.” (Colin Angle, 60:39)

• Reflections on Grit and Serendipity:

  “The journey had some amazing serendipitous moments, but they were enabled by sitting back and actually doing the work. ... I’ve got one big disappointment and thousands of bright shining moments of innovation and steps forward. And I like those odds.” (Colin Angle, 62:06)
