"Remember when a Roomba recorded a lady on the toilet, and images from the video ended up on Facebook? It's the type of horror story that rarely happens, yet once is enough to make you second-guess the smart home products you bring into your personal spaces forever.

It's an upcoming robot vacuum and mop that has been in development for six years by ex-Google Nest engineers Mehul Nariyawala and Navneet Dalal. It stands out from other consumer options because of the privacy it offers. The device doesn't require a connection to the Internet or cloud and performs all processing on-device."
