Our Verdict

iRobot Roomba S9

iRobot Roomba 694

The iRobot Roomba S9 is better than the iRobot Roomba 694, which isn't surprising given that the S9 is the premium option. The premium-priced S9 feels better built, has an onboard HEPA filter, uses a larger dustbin, has a far more advanced suite of automation capabilities, does a better job of maneuvering itself, and performs better on all surfaces. However, the 694 incurs lower recurring costs.
