TL;DR
iRobot recently filed for bankruptcy and is set to be acquired by a Chinese consumer-goods firm. The first Roomba, launched in 2002, succeeded by using cheap hardware and a behavior-based software architecture pioneered at MIT, a contrast with many modern robot vacuums that layer on cameras, mapping and apps.
What happened
iRobot announced bankruptcy and the company will be acquired by a Chinese consumer-goods manufacturer. The story prompted a look back at what made the original Roomba notable. Debuting in 2002, that model was an inexpensive, fully autonomous floor cleaner built from off-the-shelf parts and priced around two hundred dollars. It did not store maps or rely on powerful sensors; instead it combined simple, continuously running behaviors to cover floors, cope with obstacles and keep working even when individual parts underperformed. The design lineage traces to Rodney Brooks’s behavior-based robotics work at MIT and the behavior language some researchers used there. Joe Jones, who adopted those ideas, helped bring the approach into iRobot, which earlier built custom and military robots before shifting to a consumer vacuum. Over time, robot vacuums accumulated features like cameras, network links and vSLAM mapping that depart from the original Roomba’s minimal architecture.
Why it matters
- Demonstrates how software architecture can compensate for modest hardware to produce reliable consumer robots.
- Highlights a trade-off between adding advanced features and preserving robustness, affordability and simplicity.
- Suggests that design choices—rather than only hardware improvements—shaped wide adoption of early consumer robots.
- Raises questions about product direction as ownership changes and as the market emphasizes new features.
Key facts
- iRobot announced bankruptcy and is to be acquired by a Chinese consumer-goods manufacturer.
- The original Roomba was introduced in 2002 and was the first broadly successful home robot.
- That early Roomba used low-cost, off-the-shelf components and sold for about two hundred dollars.
- iRobot ultimately sold more than forty million Roombas based on that platform.
- The original device operated autonomously without requiring the user to build maps or program routines.
- Its resilience came from software that ran simple, concurrent behaviors; it could continue working despite unreliable parts or unexpected environments.
- The behavior-based approach was developed from Rodney Brooks’s work at MIT and a behavior language some researchers used there.
- Joe Jones, an engineer influenced by Brooks’s methods, pushed iRobot to build a consumer vacuum after work on custom and military robots like PackBot.
- Modern robot vacuums often add cameras, networking, phone apps and vSLAM-based mapping, diverging from the original simplicity.
What to watch next
- Whether the new owner will change product strategy or return to simpler, behavior-led architectures — not confirmed in the source.
- If future models prioritize robustness and low-cost components over advanced mapping and connectivity — not confirmed in the source.
- How the market responds to feature-heavy robot vacuums versus simpler, lower-cost designs — not confirmed in the source.
Quick glossary
- Behavior-based robotics: An approach where robots run many simple, continuously operating programs (behaviors) that directly connect sensors to actions instead of building detailed internal maps.
- vSLAM: Visual simultaneous localization and mapping: a method that uses camera data to build maps and track a robot’s position in an environment.
- Actuator: A component, such as a motor, that converts control signals into physical motion or action.
- Sensor: A device that measures physical properties (like proximity, light or motion) and provides input data to a robot’s control system.
- Autonomy: The capability of a system to operate without real-time human control, often making its own decisions based on sensor input and software rules.
Reader FAQ
Why did the original Roomba succeed?
Its low cost, use of off-the-shelf parts and a behavior-based software design that prioritized robustness in unpredictable home environments drove broad adoption.
Did the original Roomba build maps of rooms?
No. It did not have enough memory to store maps and instead used simple coverage behaviors to clean floors.
Who developed the behavior-based approach behind the Roomba?
The approach traces to Rodney Brooks’s work at MIT; Joe Jones adopted those ideas and helped bring them into iRobot.
Are modern robot-vacuum features like cameras and apps necessary?
The source notes some additions, such as stronger vacuums and bigger batteries, may be needed, while other features could be unnecessary; it does not give a definitive list.
Is iRobot still independent?
No. The company announced bankruptcy and will be acquired by a Chinese consumer-goods manufacturer.
A couple of weeks ago, iRobot announced bankruptcy. The pathbreaking Boston-area company that makes the Roomba will now be owned by a Chinese consumer-goods manufacturer. People argue about who is…
