iRobot is the biggest name in home robotics thanks to its Roomba line, a robotic army of indoor cleaning bots that will suck up the dust and dirt on your floors. But what about that other giant flat surface you own that constantly needs maintaining? For that, the Roomba lawnmower is finally here: the iRobot Terra.

Hard to believe it’s taken them 11 years to plot this out, but maybe it’s worth it in the end versus their competitors.
