Our Verdict

iRobot Roomba S9

iRobot Roomba 694 [690, 692]

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 suit of automation capabilities, does a better job of maneuvering itself, and performs better on all surfaces. However, the 694 incurs lower recurring costs.
