Since CNET started testing robot vacuums, in the early days of the first Roomba, we’ve worked hard to craft comprehensive testing procedures to evaluate every robot vacuum for the things that matter for buyers. Our lab experts have tested over 100 robot vacuums and counting, evaluating them for cleaning performance, navigation ability, object avoidance and more. Price and special features also play a role in our overall rating and buying advice.
Below, we’ve laid out the comprehensive set of lab tests we run on each and every robot vacuum that’s sent to the lab. Our tests are also always being tweaked and refined to generate the most consistent and reliable results, but the current testing procedures are accurate as of this writing. We’ve tested 24 robot vacuums under the new procedures, with more coming soon.
