Obviously, battery life is important since you’ll probably want to clean more than one room in a shot. All of the cordless vacuums we tested had a battery life of at least 40 minutes in standard cleaning mode. I tested each by cleaning all three floors of my home (upstairs, downstairs and basement) on a single charge with the machine running in its standard (“auto”) mode and none of them ran out of juice before I could finish the third floor. That said, extra battery life can come in handy if you’re switching between power modes since “max” or high-power programs use more energy.
