Our Verdict
iRobot Roomba j7/j7+
iRobot Roomba j9+
The iRobot Roomba j9+ is essentially an upgraded version of the iRobot Roomba j7/j7+ but with a few added quirks. It has a higher-capacity battery that allows it to run longer on a single charge but at the cost of a slower charging time and a slightly more powerful motor. Only the j9 features a Dirt Detective system that allows it to identify and prioritize cleaning areas that see heavy soiling, but this feature is a little buggy, frequently throttling suction to save power, even when an area could use more cleaning.
