Compare the picks

Specifications are manufacturer rated as listed, collected 21 October 2026.

How we scored them

The Gear Score weighs dust performance, build quality, value, safety and warranty. Only the WEN states a HEPA-grade filter; three of the five state a warranty term. How we pick explains the weights.

Scores run from 9.2 to 9.8: each product’s point total is placed on that range, so more points always means a higher score.

Buying guide: what matters in the best shop vacuum for auto body dust

Filtration: HEPA matters for fine dust

Auto body dust is fine, and a standard filter lets the finest particles through. The WEN VC4710 has an F9 HEPA filter stated to fight fine dust particles as small as 0.3 microns, the only HEPA-grade filter here. The DEWALT dust separator captures wood chips and debris before they enter the vacuum, reducing suction loss from clogged filters. If you sand filler regularly, filtration is the first spec to check.

Capacity and power

The WEN is 5 gallons and 10 amps, the largest vac here. The STANLEY is 3 gallons with a 3 peak HP motor at 1200 watts and an 11 liter tank. The DEWALT separator is 6 gallons but is an accessory, not a vacuum. The cordless 20V vac is 2.6 gallons. Bigger tanks mean fewer emptying stops during a full-car cleanup.

Corded or cordless

The STANLEY, WEN and RIDGID are corded; the RIDGID has a 20-foot cord and a 7-foot hose for reach around a car. The cordless 20V vac runs on the DeWALT 20V MAX battery system, with the battery and charger not included. Cordless suits quick cleanups between jobs; corded suits long sanding sessions.

Blower and extras

The WEN doubles as a blower and a vacuum, useful for blowing dust out of crevices before vacuuming. It has onboard storage for attachments and a carrying handle. The RIDGID has a 1-7/8 inch hose diameter stated for clog-free performance. The DEWALT separator saves filter and dust bag replacement cost.

Noise: 70 to 82 dB

The stated noise levels here span 70 to 82 dB. The STANLEY states 70 dB and the ReliaRoads 20V states 70 dB, the lowest stated figures of the five. The RIDGID states 80 dB and the WEN states 82 dB. Auto body sanding sessions run long, and a vacuum you run for an hour matters more for comfort than one you run for five minutes. If you sand filler every weekend, the lower stated figure is worth weighting against capacity and filtration, though the listing gives no distance or weighting for any of these numbers.

Weight and portability

Portability figures vary widely. The STANLEY states 8 pounds with a sturdy top handle for carrying, at 14 x 11 x 15.95 inches. The ReliaRoads cordless states 6.6 pounds with a carry handle, at 16 x 11 x 11 inches, and its body detaches for quick debris disposal. The RIDGID states 14.7 pounds with 4 wheels and 2 handles, at 14.31 x 20.62 x 16.75 inches: rollable rather than carryable. The DEWALT separator states 12 pounds at 15.9 x 15.9 x 31.4 inches on a 4-caster base, stable and easy to move around the workshop. The WEN lists a compact lightweight body and carrying handle without a stated weight. If your shop has steps or you load the car, the 8-pound and 6.6-pound units have an edge; if the vac lives in one bay, wheels matter more than pounds.

Hose and cord reach around a car

Reach decides how often you move the vac. The STANLEY states a 4-foot hose and 6-foot power cord, with over 10 feet of cleaning reach stated, plus cord wrap on the top handle. The WEN states a 5-foot dust hose with two extension tubes. The RIDGID states a 7-foot hose and a 20-foot cord, the longest reach here. The ReliaRoads is cordless with a 6.56-foot hose in a 1-1/4 inch diameter, so reach is never limited by an outlet. The DEWALT separator has 1-7/8 inch or 2-1/2 inch ports stated to fit most vacuum cleaners, so it slots into whatever reach you already own. Measure from your nearest outlet to the far end of the car before you buy.

Suction and airflow figures, kept honest

The listings state power in different units, so compare like with like. The STANLEY states a 3 peak HP motor at 1200 watts and 10 amps, with maximum suction of 50 inches. The RIDGID states a 5.0 peak HP motor at 900 watts and 9 amps. The WEN states a 10-amp motor. The ReliaRoads states 45 CFM airflow and 12.1 kPa suction power on 80 watts. Peak HP is a marketing figure, not a laboratory measurement, and it is not comparable to amps or watts across brands; CFM measures airflow and kPa measures suction, and they describe different things. None of the listings gives a sealed-suction figure in comparable units, so treat power as one input among several, not the ranking column.

The dust separator play

The DEWALT DXVCS002 is not a vacuum at all: it is a 6-gallon cyclonic separator that captures debris before it enters your vacuum, reducing suction loss from clogged filters and saving filter and dust bag replacement cost. The stated applications include wood chips, drywall dust, concrete dust, metal shavings, water, soot and ash. The parts are stated as durable, high-quality and heat-resistant with an anti-clogging design, and the 6-gallon poly bucket empties easily on its 4-caster base. A separator makes the most sense when you already own a shop vac and your filters clog often from sanding dust; it makes no sense as a standalone purchase, since the vacuum cleaner is not included.

Filters: foam, cartridge and HEPA

Filter type is the most consequential spec for fine auto body dust. The STANLEY ships a foam filter and a reusable dry filter, stated for both wet liquid spills and dry debris. The WEN uses a cartridge filter with an F9 HEPA rating stated for fine dust particles as small as 0.3 microns, the only HEPA-grade filter here. The ReliaRoads uses a washable mini filter cartridge, and its spec table lists a HEPA filter type. The RIDGID uses a cartridge filter with a patented Qwik-Lock design that makes filter changes easy with no additional parts or tools. The DEWALT separator is cyclonic rather than filtered, with an anti-clogging design. For wet pickup, keep the foam filter in; see our shop vacuum for wet pickup guide for picks chosen for that job.

Cordless math: the 20V pick

The ReliaRoads is a bare tool: the battery and charger are not included, and it is designed for the DeWALT 20V MAX battery system, running on DeWALT batteries up to 5Ah for up to 30 minutes of stated runtime. It states two power levels, a blowing feature and a washable filter. The cordless math is simple: if you already own DeWALT 20V tools, the runtime costs you nothing and 30 minutes covers a lot of between-job cleanups; if you own no DeWALT batteries, price the battery and charger into the purchase before comparing it with the corded picks.
