Our Verdict

iRobot Roomba S9

Ecovacs DEEBOT OZMO T8 AIVI

The iRobot Roomba S9 is a better robot vacuum than the Ecovacs DEEBOT OZMO T8 AIVI. The iRobot is easier to maintain and offers a better cleaning performance on all surface types. However, the Ecovacs has fewer recurring costs and has a mop attachment.
