Roomba
A roomba is an automated computerized vacuum cleaner that has a sensor almost everywhere that detects if there's a obstruction or wall and it would change direction. The first roombas cleaned randomly that's why early version of this vacuum cleaner takes so long to clean. Now newer versions have something called VSLAM(Vision Simultaneous Localization and Mapping) is basically the roombas take pictures of your room and it knows if it had really been there so it cleans effectively. Some roombas also offer Wi-fi connectivity so you can connect your smarthphone or tablet and program the roomba where and when to clean your room. Some users complain about the battery life the roomba but there are multiple third-party battery devices out there that improves the battery life significantly.
