The two companies say the aim is to make smart homes “more thoughtful” by leveraging the unique dataset collected by iRobot: maps of customers’ homes. > iRobot’s latest Roomba, the i7+, creates maps using a combination of odometry data (measuring how far the robovac’s wheels move) and low-res camera imagery. The resulting maps can be used to create custom cleaning schedules or to let users ask their Roomba to vacuum specific rooms. An integration with Google Assistant lets customers give verbal commands like, “OK Google, tell Roomba to clean the kitchen.”
