iRobot hasn’t changed the basic formula of its Roomba robot vacuums since the product line was first launched in 2002, but each new generation brings small improvements that make using the bots a little bit easier.

The i7+ doesn’t actually fling dirt into your garbage after each clean; instead, it uses a hopper attached to its charging station as an intermediary.
