Over the past 10 years, we've tested dozens of robot vacuums, both by performing objective tests as well as real-world setups. Each model we review is first evaluated to see how well it can pick up three types of debris. We measure out 20 grams of Cheerios, 20 grams of kitty litter, and 20 grams of pet hair. Next, we scatter each individually across a hardwood floor, and then weigh the contents of the robot vacuum's dustbin to see how much of each it picked up. We then repeat the same three tests on a low-pile carpet. Afterwards, the robot vacuum receives a cleaning performance score, which is the percentage of debris it was able to collect. After we record each robot vacuum's scores, we let these machines loose in our tester’s home to see how each holds up in terms of navigation, Top 3 Automatic Vacuum Cleaners obstacle avoidance, and coverage in real-world testing.
