Dirty Car? Make Cleaning a Snap with these Car Vacuums.

"Hearst Magazines and Yahoo may earn commission or revenue on some items through these links."

Cars are chock-full of nooks and crannies where dirt, food and other debris like to settle, and although you can technically use your Dyson (or whatever other brand you prefer), the compact nature of most automobiles makes using a full-size canister vacuum or an upright vacuum almost impossible.

The experts in the Good Housekeeping Institute's Home Care & Cleaning Lab have tested a wide range of vacuums over the years, from stick vacuums to robot vacuums. Our rigorous testing on different surface types, like hardwood floors, and with different dirt types, like pet hair, has helped us continue to make the most relevant and up-to-date recommendations in the field. With special attention to the needs of car cleaning, we've rounded up our top-tested picks for vacuuming your vehicle.

To really detail your car — getting into the tight areas under seats, between leather seams and into little compartments—you'll need a handheld cordless vacuum designed for compact areas. With new innovations in the market launching all the time, these portable vacs are quickly rising up to rival their larger counterparts in terms of dirt pickup and overall performance, and their condensed size makes them a cleaning asset both in your car and in your home.

20V MAX Cordless Wet/Dry Portable Vacuum

In our latest test of handheld car vacuums, this versatile vac from Dewalt scored the top score for removing dirt of all types. Cleaning Lab analysts found that this vacuum removed 99.9% of small particle dirt and 94.7% of large particle dirt in a single back-and-forth swipe from low-pile carpet (the kind you find in most cars). Analysts were also impressed with the attachments for this vacuum, like a hose, crevice tool and several types of brushes and bristles, letting you tackle messes in the compact frame of a car easily - though they're sold separately.

With suction strength as powerful as this vacuum's, unfortunately this model is particularly heavy, making maneuvering it a little more difficult than some of the more compact models. Nevertheless, an extra pound and a half of weight means nothing considering how well it picks up dirt. Testers also noted that the vacuum doesn't come with its own battery pack - meaning you'll need to factor that into the price. However, if you already own any other Dewalt lithium-ion-powered hand tools, you'll likely have just what you need to get up and running.

20V Power Share Cordless Cube Vac Compact Vacuum

Worx had a stroke of genius with this vacuum: Rarely do we see a handheld vacuum that features a hose instead of being a self-contained unit, and we're pretty excited about it. The hose stretches four feet, and with several attachments it can easily pick up dirt in the most hard-to-reach places of a car.

This vacuum also performed exceedingly well in our suction testing, removing an average of 94% of dirt in one swipe — without even being on its highest setting. The one quibble we have with this vacuum is the dust compartment. Unlike some other models, this vacuum's dust cup isn't removable, so you have to bring the whole vacuum with you when you go to empty it, and cleaning it can be a little intensive. That said, the dust cup is sizable compared with the overall volume of the vacuum, so you may not need to empty it as much.

AeroSlim Cordless Handheld Vacuum

Clocking in at under $50, this vacuum shows that you don't need to spend a fortune to make your car's more modest messes disappear. For the price, this vacuum has impressive suction and was able to clean up smaller messes quickly in our tests. The USB feature also makes charging in the car convenient, so you can keep it in your vehicle.

You won't mind looking at it, either — it boasts a sleek, modern design. Take note: Despite its suction power, this vacuum features a very small dust cup, meaning that for bigger messes you may need to stop and empty it more frequently than some other models. But for the price, we think an extra trip to the trash is worth it.

ONE+ 18V Cordless Wet/Dry Hand Vacuum Kit

For a true detailing experience at home, it pays to have a variety of attachments at your disposal, including a crevice tool for nooks and crannies and a brush for stubborn debris like pet hair. This cordless handheld comes with an impressive array: four dedicated tools to help you get the job done. It even comes with a squeegee to pick up liquid spills — great for families with young kids or for the occasional coffee mishap.

The vacuum does need a separate battery and charger, but for your convenience, it's included in this kit. If you already have a RYOBI battery, opt for the standalone vacuum to save a little bit of money. While our Lab pros haven't tested this specific model, we have tested the brand's dry-only vacuum with much success. (It scored so well that it was a previous Cleaning & Organizing Award winner.) The only downside we see with this particular model: Dust bin capacity is limited, so you'll likely have to empty the canister a few times during bigger jobs.

AdvancedClean+ Pet Hand Vacuum

Pet hair gets everywhere, and if you've ever traveled in the car with your pet, you know how much they can shed on your seats and floor. What sets this model apart is its ability to pick up pet hair, due to its motorized pet brush attachment with rubber bristles. The AdvancedClean+ Pet Hand Vacuum earned a spot on our list of the best vacuums for pet hair, competing right alongside upright and stick vacuums, which is impressive considering its size.

Our testers also loved how quiet this vacuum is. In fact, after being examined by the independent certification program Quiet Mark, it received a three-star rating, the quietest rating a vacuum can get. It should be noted that the air vents on the sides of this model push out air pretty strongly, so you may have to pay attention as you vacuum to make sure you don't accidentally blow your mess to another location.

How we test car vacuums

To find the best car vacuums, we gathered data on five of the newest models to hit the market, spending more than 10 hours performing five different tests that yielded more than 40 data points.

All vacuums were tested on low-pile carpet to mimic the texture of car rugs, and different types of debris, including crushed cereal, baking soda and almost two pounds of oats, were cleaned using the vacuums. We also weighed the vacuums, assessed their ergonomics and measured their loudness when operating to determine how easy and comfortable they were to use.

We also reviewed and incorporated data points from previous handheld vacuum tests. In our most recent test of handheld vacuums, the Good Housekeeping Institute Cleaning Lab tested 19 models from 14 different brands. We test all handheld vacuums on bare floors and low-pile carpets for how well they pick up light debris like sand, baking soda, dry oatmeal, orzo pasta and pet hair. We also test their suction with heavy items, like screws and nuts.

What to look for when shopping for a car vacuum

When weighing your options, factor in these four important elements to find the right car vacuum for your needs:

✔️ Run time: A vacuum with a longer run time means fewer charges between cleanings and not having to worry about charging every time you use the vacuum. For vacuums that have separately sold batteries, choose a battery with a larger capacity to keep your vacuum running clean after clean.

✔️ HEPA filtration: Though not always necessary, a HEPA filter in your vacuum can help prevent small particulate matter, like pet dander, pollen, dust mites and ash from smoke, from being recirculated into the air as you vacuum. People with allergies or air-pollution sensitivities should look for vacuums that feature HEPA filters to better capture irritating particles.

✔️ Attachments: When you're cleaning a space that has lots of tight crevices and is made from a variety of different materials, like the interior of a car, attachments are your best friends. Look for a vacuum that has a crevice tool to get into the little nooks where dirt likes to settle, and consider one with a rotating brush attachment to easily remove hair from fabric materials.

✔️ Charger type: If you plan on keeping your car vacuum in your car, you'll want to find a vac that features a USB charger. That way, you'll be able to keep it charged with the auxiliary power outlet found in most cars, so you're prepared when a mess arrives.

What is a good suction power for a car vacuum cleaner?

If we want to get super technical, according to ASTM F558-13, the standard test for measuring air performance of vacuum cleaners, the air power (reported in watts) of a vacuum is a description of the net time rate of work performed by an airstream while expending energy to produce an airflow under specified air-resistance conditions. In other words, a vacuum with a higher air power will have greater suction power.

When you're looking for a car vacuum, the most important thing is not to confuse air power with electrical power (reported in volts). A vacuum with higher electrical power will not necessarily provide greater suction. Air power is often not reported by vacuum manufacturers, whereas electrical power typically is.

Due to the complex nature of calculating air power, and the fact that not all manufacturers report air-power wattage, we measure vacuum pickup in a more practical way: The Cleaning Lab uses pickup tests to approximate suction power as a percentage of deposited matter that is recovered by the vacuum after one forward and one backward pass of the vacuum. Seven out of the nine vacuums featured in this article had an average pickup of more than 80% of deposited dirt after just one complete pass (the other two were not included in the initial round of testing), meaning they're powerful enough to clean up most messes with minimal effort.
