iRobot Roomba 960 vs iRobot Roomba i3

The iRobot Roomba 960 is slightly better than the iRobot Roomba i3. The 960 incurs lower recurring costs, is more effective on low-pile carpet, does a better job dealing with pet hair, and can climb over obstructions like rug tassels with less difficulty. It also comes with a virtual wall tool that generates a barrier that the vacuum won't cross. However, the i3 does have a self-emptying function that reduces hands-on maintenance requirements since it can automatically transfer debris from its internal dirt compartment to an external dustbin attached to its charging dock.
