Best Car Vacuums for Easy Cleaning, From Cordless to Corded Models

Vehicle owners range from those who rarely give their car a second thought to those who border on the obsessive when it comes to car maintenance. The former often have a passenger or back seat that doubles as a junk drawer where you can find everything from a spare hat to a pen to a week-old granola bar. The latter are the type who prohibit eating or drinking of any kind in their car, insist on passengers wiping their feet before getting inside, and routinely use a pressure washer to blast road muck from the exterior.

Obsessive types notwithstanding, many people find it difficult to remember to regularly clean the interior of their car, van, or truck. Matthew Baratta, VP of Operations at Daimer Industries, a globally recognized leader in innovative and technologically advanced commercial and industrial cleaning equipment, says that regular vacuuming is essential to prevent potential damage to your car’s interior caused by dirt, debris, and road salt.

Jason Jaap, founder of Jim's Scratch & Dent remembers one case of a car with an interior so filthy “that it took almost eight hours of work by a complete team to get it back to the condition in which it had naturally come.” He also said that he’s found all sorts of odd objects while vacuuming interiors; things like forgotten toys, unfinished snacks, and all kinds of simple items you’d never expect to find in someone’s car.

To prevent your vehicle from becoming a similar, cautionary tale, add ‘vacuum car interior’ to your weekly or (at least monthly) chore list. There are numerous vacuum cleaners available to assist you, with varying features, attachments, and price points. I put together this list to help you find the best one for your needs.

Our picks for the best car vacuums

How we selected the best car vacuums

To select the best car vacuums, I consulted online customer reviews, documentation, and professionals in the cleaning and auto detailing businesses to come up with this list of recommendations. I took into consideration price, available attachments, ease of use, and features to find the best choices for the largest range of consumers.

What to consider before buying car vacuums

Corded or cordless

While cordless vacuums generally have lower suction capabilities than corded models, they provide a portability component that allows you to keep them in your car to tackle messes and spills shortly after they happen. They’re also easier to maneuver into all the nooks and crannies of your vehicle’s interior.

Their smaller canister capacities mean you’ll need to empty them more frequently, though. The runtime of most cordless models falls somewhere in the 15 to 30 minute range, so they also need to be recharged often.

Speaking of, consider also the charging method. Some require a USB-C cable while others use a removable battery pack (like power tools). The former can be charged via your vehicle’s USB port while the latter must be inserted into a charging station plugged into a standard wall outlet. Vacuums that use removable battery packs mean you can keep extra charged ones on hand.

Corded vacuums, on the other hand, offer unlimited run times, more powerful suction, and larger dust and debris canisters.

Canister capacity

As far as canister capacity goes, consider what type of debris you might encounter and how often you anticipate needing to sweep. Compact, handheld vacuum models offer convenience and portability but they also usually have to be emptied often, while larger corded vacuums can feature capacities of 6 gallons or larger—that’s a lot of dirt!

Suction power

Choosing a car vacuum with the requisite suction capacity is important for achieving maximum cleanliness, says Jaap.

“From personal use, vacuum cleaners with suction power of about 12 amps or higher produce desirable results in clearing dirt, mud, and other carbonizing matters from the interior parts of a car,” he said.

Filter system

Look for vacuums with filtering mechanisms to guarantee comprehensive work cleaning, suggests Jaap. HEPA filters are great for siphoning dust and other contaminants.

Attachments

One of the most important features are the number of different attachments available that provide you with ample cleaning options for any fine crevice and tight corner you might find in your vehicle, says Jaap. Look for a vacuum with a full range of attachments, including multiple brushes and angled tools.

Frequently asked questions (FAQs)

How many times should I vacuum my car?

As an auto detailer professional, Jaap recommends cleaning your car’s interior at least once a week to keep any dirt that accumulates from general use from getting out of hand. This is especially important during the winter months and for those who operate a work truck for a construction site, farm, or ranch. Vacuuming once a week ensures that salt, dirt and other debris don’t creep under the floor mats and cause damage to the upholstery, said Baratta.

If, however, you live in a warm climate and only drive your car for everyday activities such as work and errands, you can likely get away with detailing every one to three months, Baratta says. Note that the key stipulation here is “warm climate.” Winter road salt is corrosive and can cause damage if left to fester.

How much suction power is best for a vacuum cleaner?

“Air watts are the first indicator of the overall suction power of a vacuum as they combine the airflow power with the water lift metric,” explained Baratta. This metric (determined by multiplying the water lift by the airflow cfm and dividing by 8.5) ranges significantly between handheld vacuums and large commercial wet and dry extractors used in auto detailing shops.

Most handheld models will have suction powers of around 15 to 30 air watts, says Baratta. Depending on the size of the motors, commercial and industrial extractors used for auto detailing can be well over 1000. Cleaning all the corners and crevices inside your car or truck will be easier with higher suction powers.

“Using a standing model vacuum with a hose and various attachments may be beneficial as these larger models come with higher suction power and wand attachments specifically made for crevices,” said Baratta.

To determine which level of suction power is best for your situation, consider your lifestyle. Does your vehicle get a lot of dirty foot or paw traffic? Do you haul things regularly? Do you spend a lot of time outdoors, or do you traverse dirt roads, etc? You also want to consider your budget, and what level of portability you want in a vacuum. It might make sense to keep a small, handheld one in your car for quick sweep ups and a larger, corded model in your garage for more thorough cleanings.

Can I plug my car vacuum into the auxiliary outlet without draining my car’s battery?

Jaap says yes—as long as you use an appropriate automotive vacuum and plug it directly into your car’s auxiliary outlet. If you do this, though, he recommends keeping the engine running to prevent mechanical issues or putting undue strain on a car battery. “On average, an auxiliary vehicle outlet produces 120 watts,” says Baratta, “so your vacuum's wattage should be below this to avoid damage.”

How do you know if a vacuum has good suction?

Most manufacturers should include an air watt measurement for their vacuums. The higher that number, the more suction power the vacuum will have.

Can I use a regular vacuum to vacuum my car?

“Yes,” said Baratta, “you can use a regular vacuum in the car, although it may be very difficult to maneuver without the proper attachments.” If for instance, your vacuum comes with a few standard wand attachments, a long cord and hose, you can plug it into an outdoor outlet and use it in the car quite easily. However, he pointed out, if you’re looking for a more on-the-go solution a handheld model might be best.

The car vacuum cleaners are lighter and easy to carry and maneuver, especially inside a car, said Jaap. With features that target each unique space found in your vehicle, a car-specific vacuum will allow you to clean more efficiently. Work smarter, not harder.
