iRobot hasn't given up on developing Roomba's lawn mowing sibling

You know how long it’s been since we first heard that iRobot’s making a robotic lawn mower? Nine years. After almost a decade of wondering if we’ll ever see Roomba’s more outdoorsy sibling, iRobot’s finally giving us a glimpse of how the device will work through an FCC filing.

Seriously? But honestly, why am I surprised?
