Our Verdict

iRobot Roomba E5

iRobot Roomba 981

The iRobot Roomba 981 is a better vacuum than the iRobot Roomba E5. The 981 delivers better performance on all surface types, especially bare floors. It also has fewer recurring costs, a bigger dirt compartment, and better automation features. On the other hand, the E5 is slightly smaller and lighter, making it a bit more portable and easy to store.
