How we test vacuums: Roombas, fake poop and lasers

From CNET.

From simple straight line tests to astrophotography techniques to poop avoidance tests, here is how we gauge the performance of all types of vacuums to find the best model for you.

We test upright vacs, stick vacs and robot vacuums in our custom-built lab. We used advanced calculations to measure how good they are at their primary job, and we also use long-exposure photography to capture the navigation methods of these robot models. Plus, we develop new tests all the time as the technology of the machines themselves advances.
