Clean floors, dirty comments
Revisiting the original Roomba and its simple architecture
Fans mourn old Roomba as the “laser map” crowd says iRobot blew it
TLDR: iRobot’s collapse sparked a brawl over Roomba’s soul: was the simple original genius, or did skipping laser mapping doom it? Nostalgia dukes it out with frustration as users recall friendly handles and beeps, allege subreddit censorship, and praise cheaper, smarter rivals.
iRobot’s bankruptcy has the internet vacuuming up feelings, and the comments are juicier than a dustbin on cleaning day. The article praises the original Roomba’s simple, scrappy brain—built to stumble, recover, and still get the job done—while the crowd splits into camps: the laser-map loyalists vs. the vibes-and-brushes nostalgics. One side argues today’s camera/laser navigators (they build room maps like GPS for your living room) are cheaper and smarter, saying software beats bulky hardware. Another side blasts iRobot for skipping laser sensors, joking that modern Roombas only have “vibes” about where they are, not a clue.
Then the drama turns spicy: a user claims the Roomba subreddit bans criticism, which sparked corporate copium memes and banhammer jokes. Nostalgia hits hard too—one commenter says an early budget Roomba had a handle, clear buttons, and friendly beeps, while a pricier auto-empty model ditched the handle and sang cryptic tones like a mystery train station PA. Another links the nerdy roots—Subsumption architecture—the OG “do simple things well” method that made the first bot charming. There’s even a fun tidbit (from a commenter) that early Roomba code lived in Lisp. Verdict: the floor may be clean, but the comments are a glorious mess.
Key Points
- •iRobot announced bankruptcy and is set to be owned by a Chinese consumer-goods manufacturer.
- •The original Roomba (2002) used low-cost, off-the-shelf hardware to hit a ~$200 price and sold over 40 million units.
- •Roomba’s autonomy relied on software designed for reliability with unreliable parts and unstructured home environments.
- •It used coverage heuristics instead of room mapping, handled obstacles reactively, and degraded gracefully when components failed.
- •Roomba’s software roots trace to Rodney Brooks’ 1980s MIT AI Lab work, including a “behavior language,” with contributions from Joe Jones; iRobot also built revenue with PackBot contracts.
