A good shop vac is the secret weapon of a lot of car detailers. It has more raw suction than a household vacuum, pulls sand out of carpet, handles wet messes like spilled drinks and carpet shampoo, and won’t mind dog hair or gravel.

For car work, what matters most is reach and maneuverability: a long hose, a long cord or no cord at all, and a vac you can easily move around the car or into the trunk.

At a glance

Test notes are from Bob Vila's shop vac testing, which used water, damp and dry sawdust, and leaf debris. They didn't test car detailing specifically; we've weighed their results by what matters inside a car.

1. DeWalt 6-Gallon 5 HP Wall-Mounted Wet/Dry Vac: Best for the garage

Best for: Anyone who details in the same garage every time.

This DeWalt mounts on a single wall stud, so it’s always ready and never in the way. Bob Vila’s testers found its hose the most flexible and durable of any they tried, which matters when you’re snaking it through a door and around seats. The remote on/off means you can switch it on from inside the car, and it comes with plenty of attachments plus a muffler to cut noise.

What bugs us: At 6 gallons, it’s small for big spills, and it has no wheels if you want to take it elsewhere.

Skip it if: you clean cars in a driveway away from an outlet.

2. Milwaukee M18 Fuel 6-Gallon Wet/Dry Vacuum: Best cordless

Best for: Driveway detailers and Milwaukee M18 tool owners.

With no cord to snag on tires or drag across paint, cordless is ideal for car work. Bob Vila’s testers found the Milwaukee powerful, and its battery recharged in about an hour. The tank snaps on and off its base for easy emptying.

What bugs us: It weighs 26 pounds, and it’s sold as a bare tool, so you’ll need an M18 battery and charger.

Skip it if: you don’t already own Milwaukee batteries. It gets expensive.

3. Ryobi 18V One+ 1-Gallon Wet/Dry Vacuum Kit: Best compact

Best for: Quick weekly cleanups, and keeping a vac in the trunk.

At 7 pounds, this little Ryobi is easy to carry into the back seat. Bob Vila’s testers found it strong for its size, and it held up through more than an hour of testing. It comes with a battery and charger.

What bugs us: It’s slower on heavy debris, has no wet-floor nozzle and takes about 2 hours to charge.

Skip it if: you deep-clean carpets with a shampooer. You’ll want a bigger tank.

4. Stanley 5-Gallon 4 Peak HP Wet/Dry Vac: Best value

Best for: Budget shoppers.

Bob Vila’s value pick handled sawdust, leaves and standing water well. Its rear port turns it into a blower, putting out up to 85 CFM, which is useful for blowing dust out of vents and door jambs. It rolls on casters.

What bugs us: The hose and cord are shorter than some rivals, which matters around a car. There’s no drain plug, so you tip it to empty.

Skip it if: you need a long reach. Add an extension hose.

5. Ridgid 12-Gallon 5.0 Peak HP NXT Wet/Dry Vac: Most power

Best for: Big jobs, wet cleanups and garage-wide use.

Bob Vila’s best overall shop vac had the strongest wet and dry pickup in testing. Its wet nozzle has a squeegee, and a front drain plug lets you empty water without tipping the tank. A 15-foot cord and 7-foot locking hose help with reach.

What bugs us: At 26.6 inches tall and 18.7 inches across, it’s big to move around a car.

Skip it if: you only vacuum floor mats.

How we picked

We relied on Bob Vila’s shop vac testing, which put each model through wet and dry tests and scored ease of use, performance, portability and value. Since car detailing wasn’t tested directly, we favored models with flexible hoses, cordless operation or easy storage. We focused on:

• Suction
• Hose and cord reach
• Portability
• Wet pickup
• Storage

We haven’t tested these vacuums ourselves. Read more about how we pick products.

Detailing tips

• Get the right attachments. A long crevice tool, a soft brush and a narrow upholstery nozzle do most of the work.
• Add a longer hose. An extra few feet makes it easier to reach both sides of the car without moving the vac.
• Use a fine-dust filter for dry work and remove it for wet pickup, following the manual.
• Agitate first. A stiff brush on carpet loosens sand and hair so the vac can pull it out.
• Blow before you vacuum. On a vac with a blower port, blow dust out of vents and seams first.

Still wondering?

What size shop vac is best for cars? A 4- to 6-gallon vac balances suction with being easy to move around the car.

Is peak HP important? It’s a rough guide. Hose design, filter and airflow matter just as much.

Can I use a shop vac to extract carpet shampoo? Yes, most wet/dry vacs can pick up the solution. Remove the paper filter if the manual says to, and empty it promptly.
