iRobot Roomba i4

The iRobot Roomba i4 has a decent performance on high-pile carpet. It picks up pet hair and large debris like sand fairly easily but really struggles to clean fine debris like baking soda. Thankfully, its performance remains consistent as the dirt compartment fills up. It also automatically adjusts its suction and height off the ground, which is helpful when cleaning high-pile carpet. Unfortunately, it has quite a few recurring costs, since a lot of parts need to be periodically replaced.
