After its go around my apartment, the i7+ is “still learning.” It’s fitting sentiment for the new Roomba, which iRobot is positioning as much as a platform as a robotic vacuum. Like a smartphone, it’s designed to learn new tricks over the life of the product, through over the air updates.

In this particular case, however, it’s learning the layout of my place. The i7+ builds on the moderately useful dirt mapping rolled out on the 900 series early last year. With a couple of cleans, the new Roomba gets to know the layout of your apartment, building a “Smart Map” in the process.
