iRobot Roomba i8+ vs Shark Matrix Plus

The iRobot Roomba i8+ and the Shark Matrix Plus are self-emptying robot vacuums exclusive to Costco retailers. Which one is right for you ultimately comes down to your priorities. The iRobot feels like the more premium product, with a much sturdier build, easier maintenance, and a slicker, easier-to-use companion app. It's also the better option if you suffer from allergies; not only does the iRobot do a better job of sealing in allergens as it cleans, but its base station uses a disposable dirtbag instead of the Shark's bagless system, so you won't have to worry about creating a plume of dust when emptying it. Meanwhile, the Shark has a LIDAR sensor that allows for quicker room mapping and slightly less sporadic navigation, even in the dark.
