Cordless vacuum cleaners are handy for cleaning in hard-to-reach spots, like under furniture and along baseboards. They're also handy for spot cleaning upholstery (especially car seats), and vacuuming up crumbs or grass on floor mats. But there are many different types of cordless vacuums, and it can be tricky to choose the one that's right for your needs.

When you're looking for a cordless vacuum cleaner, there are several things to consider: battery life, dust and filter capacity, and form factor. You want to find a vacuum cleaner that will work well in your home, and be easy to use.

For starters, battery life varies widely, from 15 to 40 minutes on average, but higher-end models can offer more powerful suction and run longer on a single charge. A lithium-ion battery, which is more energy efficient and can last for up to 16 hours, is ideal if you're going to be using your vacuum cleaner for an extended period of time.

They're also simple to empty and feature a small, compact dustbin that can be quickly emptied after each use. These are especially handy for families with children who have trouble letting go of the vacuum cleaner, or pets that shed hair frequently.

Depending on the type of cleaner you choose, you may need to empty the dust canister frequently. If you don't empty the canister regularly, it will collect dirt and debris that will clog the filter, slowing down the vacuum cleaner's performance.

If you're planning to use your cordless vacuum on bare floors, it's important to check that the model has soft rollers to protect the floor. Cordless vacuums with hard rollers can scratch bare wood, especially soft hardwoods like pine.

The best vacuums we've tested come with a variety of accessories that make it easy to get into hard-to-reach places and clean upholstery, such as sofa cushions, curtains and headboards. Generally, a cordless vacuum cleaner with a crevice tool will be the most effective in these areas.

You should also look for a vacuum that can be quickly converted into a hand vacuum. This way, you can clean your car's interior without having to leave the house.

There are many ways to choose a vacuum cleaner, but the most important thing is to think about your needs and what you're willing to pay for a product. A great vacuum is convenient and affordable, so you can get a good cleaning job done without breaking the bank.
