Dyson Cordless Vacuum VS iRobot Roomba j7
Verdict DROP IT DROP IT
The Reality The UK's Advertising Standards Authority (ASA) formally investigated the specific '10x the suction' claim after evidence and independent testing were submitted by both companies. The ASA found Dyson had misled customers by conflating suction power (a measurable airflow specification) with real-world pick-up performance (how much dirt the vacuum actually removes from a surface) -- two different things that don't necessarily track together. The ad and accompanying YouTube video were banned, and the ASA required Dyson to make the basis of any future comparative claims explicit and to hold adequate test data before making implied or stated performance comparisons. MIT Technology Review's December 2022 investigation found that images captured by development versions of the Roomba J7 series -- gathered during a 2019-2022 data-collection program with paid testers -- ended up leaking publicly. In one 2020 case, gig workers in Venezuela hired by contractor Scale AI to label objects in the images (used to train the object-recognition feature) posted at least 15 of those images to closed social-media groups, including a photo of a minor and a photo of a woman sitting on a toilet. Nearly a dozen program participants came forward after the investigation was published, saying they felt misled about how their images would be handled and viewed by outside contractors. iRobot's position is that these images came from development units under separate testing consent agreements, not from a consumer's purchased Roomba operating normally.
SHORT ANSWER
Dyson Cordless Vacuum: The UK's Advertising Standards Authority formally ruled that Dyson's '10x the suction' comparative ad claim misled customers by conflating raw suction power with real-world pick-up performance, and banned the ad.
iRobot Roomba j7: MIT Technology Review's 2022 investigation found images from Roomba J7 development units -- including a photo of a woman on a toilet and a minor -- were leaked to social media by workers at an overseas data-labeling contractor, though iRobot says these came from testing units, not consumers' purchased Roombas.
