Sure, robot vacuums are convenient and they make for great cat videos. But these devices  have the potential to collect a lot of data from the private setting of our homes. Images of children’s faces, the layout of a house, even someone sitting on the toilet were all captured by iRobot vacuum test models in North America, Europe and Asia. Those photos found their way into a private Facebook group for Venezuelan gig workers, where they were then leaked to journalists at MIT Technology Review. Marketplace’s Meghan McCarty Carino spoke to Eileen Guo, a senior reporter at MIT Technology Review, who has been investigating this.
