If you prefer a bagless design, all of the cordless vacuums in this guide fall into that category, making them easier and cheaper to maintain than bagged models. Some cordless models also have removable, replaceable battery packs, which is super handy. That means you can buy a replacement battery and install it easily, without needing to seek out professional assistance. Also, these extra batteries cost around $150-$200 a pop — expensive, yes, but nowhere near as costly as buying a whole new cordless vacuum.
