We did the research for you to find the best portable vacuums for your car.  
When you want serious power, the Armor All AA255 Wet/Dry Vacuum Cleaner certainly delivers. Dressed in the trademark orange and black of a wet/dry vacuum, it is a corded electric vacuum, but it comes with a convenient 10ft cord to allow for extended reach. For better suction, there is a 2-horsepower motor, and there is also an auto shut-off feature, which can come in handy for home use. This Armor All AA255 Wet/Dry Vacuum Cleaner also has the dual purpose of a blower, with easy transition between functions. Despite this, it is surprisingly quiet, with a built-in air and noise diffuser to minimize volume. There is a 2.5-gallon polypropylene tank, so there is plenty of cleaning that you can do without having to stop to empty your vacuum. However, all that power does come with serious heft, with this particular vacuum weighing seven pounds.  BISSELL is a popular provider of home products, and their vacuums are a reliable choice for a variety of purposes. When you need a solid but compact car vacuum, BISSELL offers the AeroSlim Lithium-Ion Cordless Handheld Vacuum. Designed for a life on the go, it features a sleek, compact design that is also easy to store in your car, office, or dorm. The AeroSlim handheld car vacuum has a 7.2V lithium-ion battery. There are up to 12 minutes of cordless cleaning power before you need to charge via the included USB charging cable or traditional wall charger. Either way, your vacuum will let you know when it’s time for a battery boost with the built-in battery indicator lights. Charging time lasts between 2.5 and 3.5 hours. Also incorporated are special features designed for effective cleanings, like dual-level filtration with a washable filter and BISSELL’s signature Easy Empty Dirt Bin. Your vacuum comes with a 2-in-1 Crevice Tool & Dusting Brush that conveniently stores right on the handheld device. Plus, this is a purchase that you can feel good about, with a portion of sales going to support the Bissell Pet Foundation for homeless pets. It takes four hours to charge, and users generally report 10-12 minutes of use before requiring a charge again. With the Hotor Portable Car Vacuum, you don’t have to worry about battery or charging because it’s corded. That cuts down on portability, but that also means lasting power that never runs out and always goes at full strength. The Hotor Portable Car Vacuum is powered by 8.8A with 12V and 106W. At about 1.3lbs, this mini vacuum is also super lightweight and designed for easy use. An LED light shines an extra light during nighttime cleaning sessions with a detachable dust cup head for easy use. With a stainless steel exterior, its design integrates a HEPA filter with washable and durable materials that are backed by a free lifetime replacement guarantee. You will also receive three different nozzles to help you get the job done. Despite its small and lightweight build, the Portable Car Vacuum Cleaner by ThisWorx has 110W of suction power at over 9A. Its thoughtful design incorporates a clear, flat bottom for an easy-to-see dirt collection, and there is a built-in LED light for better visibility. Maintenance is simple with a washable double filter that uses industry-leading double HEPA filter technology. Plus, the ergonomic design is lightweight, weighing 2.4 lbs.  This vacuum is corded but includes an extra-long 16-foot power cord that plugs into a 12V outlet. Overall, it is a miniature vacuum that is both lightweight and compact. Your purchase includes a complete vacuum kit with multiple attachments, a filter cleaning brush, an extra filter, and a travel bag. The ThisWorx Portable Car Vacuum Cleaner is available in your choice of black or white with its signature orange accents. The VacLife Handheld Vacuum with High Power (VL188) also has a stainless steel HEPA filter, similar to other models on our list. Still, as a cordless vacuum, it is lightweight and portable at about 2.5 lbs. Its handheld, the cordless design gives you greater freedom to move around; there is a built-in LED light so you can still see in dark corners. Designed for carpet, it has three different attachments with included brush and crevice nozzle tools, in addition to an extension soft pipe, adapter, and carry case. Most impressive, however, is the 20-minute runtime, the longest on our list by nearly double. There is a battery indicator light that goes from red to green when fully charged, and it takes about 2 to 3.5 hours to charge from empty. The VacLife Handheld Vacuum with High Power (VL188) is available in orange, silver, and white.

Cords: There are both corded and cordless options for car vacuums, and there are pros and cons to both. While a cordless vacuum gives you greater freedom of movement, it can be more restrictive than corded options when it comes to the length of use and battery life.Power: When you buy a car vacuum, one of the most basic things you need is the power to get the job done. A good car vacuum should have at least 15 air watts or a battery of 16V or higher.Design: The best car vacuums have a comfortable, lightweight design that does not place too much strain on your arms and wrists. Ergonomics are important to consider for longer jobs to ensure your comfort.  Battery life: While your car vacuum must have a lot of power, it will not matter if the battery is constantly running out of charge. A corded option ensures that you will never lose power as long as you have access to an outlet, but that is not the case with cordless options. The best cordless vacuums for cars can run anywhere from 10 minutes to 20 minutes, depending on the model you choose.
