MIT Technology Review revealed in 2022 that images captured by iRobot Roomba robot vacuums — including a photo of a woman sitting on a toilet — had been shared with Scale AI contractors who labeled the data for AI training. The images then leaked to public Facebook groups. The photos were taken by development-model Roombas given to paid testers, who had signed consent agreements that didn't clearly explain photos could leave iRobot. It became a landmark case on the privacy risks of home AI devices.
