Our Verdict
iRobot Roomba i7
iRobot Roomba S9
The iRobot Roomba S9 is better overall than the iRobot Roomba i7. The S9 performs better on all surface types, feels better built, has lower recurring costs, and has a maximum battery life that's more than twice as long as the i7. The i7 does come with an automatic dirt disposal feature. This effectively gives it a much larger dirt compartment via an external dirt bin that it can return to when full. However, the same option is available for the S9 at an added cost.
