If Roomba vacuums are going to feel like they're truly part of your connected home, they need to do more than dutifully clean your floors on a set schedule. Thankfully, iRobot is helping them do just that. It just added IFTTT "recipes" that tell Roomba robots when to clean or to interact with other devices. You can tell your robovac to start cleaning when you leave or stop when you get home, for starters. However, the cleverest tricks come when the robot interacts with the outside world. You can tweet to your Roomba to start a command, or have it post to Facebook or Twitter when it's done. You can even have it flash your Hue lights or play music (on Android devices) when it's finished, in case there's something you need to do immediately afterwards.
