Battery capacity is a huge consideration when you’re looking at stick vacuums. If you’re used to corded uprights, the idea that you can only vacuum for 20, 30, or 60 minutes at a time with a cordless model may surprise you. But because cordless stick vacs run on batteries, you’re cleaning time is limited by how long the charge will last. Makers should clearly tell you right on the box how long their particular model’s batteries last—but pay attention when they say “up to” x-number of minutes. Higher power settings and motorized attachments use up energy faster, so some models may only work for 10 minutes or less when you use their maximum power settings. That’s totally fine for quick tidying, but if you’re planning to use your stick vac for full-house cleanups, you’ll need one with the highest run time you can find.
