The short version: the best cordless shop vac is the DEWALT DCV581H, because it runs on either a 20V MAX battery or a mains cord — which solves the one genuine weakness every cordless vacuum has, that the pack dies long before the job does. It holds 2 gallons wet or dry behind a washable HEPA-rated filter. If you are already on Milwaukee M18, the 0880-20 is the same idea on your platform, and if you are cleaning up drywall or sanding dust, the Makita XCV11Z with a true HEPA filter is the right tool because a standard filter simply blows fine dust back into the room; NIOSH is blunt that the respirable fraction of masonry dust causes irreversible lung disease.
The honest framing for this whole category: a cordless shop vac is not a replacement for a corded one. It is a convenience tool for the ten-minute cleanups that happen constantly — the sawdust under a miter saw, the debris in a car footwell, the spill in the garage — where dragging out a 16-gallon vac and finding an outlet is more effort than the mess deserves. For full-size options see our main shop vac roundup, and the power tools and workshop hub covers the rest.
Top Picks at a Glance
Our #1 Pick: DEWALT DCV581H
Every cordless vacuum shares the same fundamental problem, and it is worth stating plainly before anything else. A vacuum motor is a continuous, high, unrelenting draw. A drill spikes for two seconds and rests; a vacuum pulls hard for as long as the trigger is on. That is why a battery which powers a drill through a whole day of cabinet installation will run a vacuum for roughly fifteen or twenty minutes. Nothing in this category escapes that.
The DCV581H is the only vac here that sidesteps it. It runs on a 20V MAX battery when you need portability, and on an ordinary AC cord when you do not. In practice that means you use it cordless for the quick jobs, and when a cleanup turns into a real one — after demolition, after a flooded basement — you plug it in and keep going indefinitely. Owners consistently describe this as the feature that made them stop worrying about batteries.
The rest is competent rather than remarkable, which is what you want. Two gallons wet or dry, a washable HEPA-rated filter that you rinse rather than replace, a flexible five-foot hose, a wide nozzle and a crevice tool. It handles water pickup properly, with the motor positioned clear of the tank. It is a tool-only purchase, which is the right structure for a vacuum: nobody should pay for a battery they already own.
Consensus Score █████████░ 8.8 — built from aggregated verified owner ratings, weighted for review volume.
The honest weaknesses: the dual-power circuitry adds weight and cost against a battery-only model; two gallons fills fast in real cleanup work; the hose is short at five feet compared with some rivals; and the HEPA-rated cartridge filter, while good, is not the sealed true-HEPA system you need for serious drywall dust. It is also loud, as every shop vac is.
The Ranked Field
Best for jobsite and garage cleanup where an outlet is sometimes available
- Runs on 20V MAX battery or an AC cord
- 2 gallon tank, wet and dry
- Washable HEPA-rated filter
- Flexible 5 ft hose with wide nozzle and crevice tool
Why buy it: the dual power option is the whole argument — battery when you are away from an outlet, mains when you are not, so a dead pack never ends the job.
Best for anyone already on the Milwaukee M18 battery platform
- 2 gallon tank, wet and dry pickup
- Certified HEPA filter
- Flexible hose, crevice tool and utility nozzle
- Runs on any M18 battery
Why buy it: if your drill and impact driver are already M18, a bare-tool vacuum costs a fraction of buying into a second battery system for the same job.
Best for a cordless vac for the garage or the car without premium pricing
- 2 gallon tank, wet and dry
- HEPA-rated filter
- 7 ft 8 in hose with onboard storage
- Runs on CRAFTSMAN V20 batteries
Why buy it: a nearly eight-foot hose on a two-gallon vac means you set it down once and reach the whole footwell of a car, which is what most people actually buy one for.
Best for drywall dust, sanding dust and tool-mounted dust extraction
- True HEPA filter, 99.97 percent at 0.3 micron
- Brushless motor for longer runtime
- Up to 57 CFM and 27 in water lift
- Wet and dry, 2 gallon capacity
Why buy it: a true HEPA filter and a sealed body is the difference between collecting drywall dust and redistributing it as an invisible haze that settles on everything for days.
Best for emptying less often on bigger cleanups
- 3 gallon tank, largest here
- Locking 1-7/8 in hose that expands to 7 ft
- Includes cartridge filter and car nozzle
- Runs on RIDGID 18V batteries
Why buy it: three gallons instead of two is fifty percent more debris between trips to the trash can, which matters more than it sounds when you are cleaning up after demolition.
Best for a lighter, cheaper battery-only version of our top pick
- Battery-only, no AC circuitry
- 2 gallon wet and dry capacity
- Washable HEPA-rated filter
- Onboard hose and accessory storage
Why buy it: dropping the mains option saves weight and money, which is the right trade if the vac lives in a truck and never sees an outlet anyway.

How We Rank
We do not buy, test or physically handle these products. For cordless shop vacs we weight filtration quality and whether the body is genuinely sealed, tank capacity against how fast it fills, hose length and accessory usefulness, runtime per battery, and the value of the platform you are buying into. Rankings come from the aggregated owner-review record — ratings weighted by review volume, plus the complaints that repeat across many reviews. Prices were current at the time of writing. Full method on how we rank.
The Cordless Shop Vacs, Reviewed
1. DEWALT DCV581H — Best Overall
Covered above. What owners praise: the battery-or-mains flexibility, solid suction for its size, and a washable filter. What owners complain about: the short hose, the small tank, weight from the dual-power circuitry, and short runtime on small batteries. The most useful cordless vac for most people.
2. Milwaukee 0880-20 M18 — Best for M18 Owners
A straightforward platform play, and a good one. Two gallons, wet and dry, with a certified HEPA filter, a flexible hose and the usual crevice and utility nozzles, running on the M18 batteries you already own. Milwaukee quotes extended runtime on their highest-capacity packs, which is the honest way to use any cordless vacuum. What owners praise: build quality, the HEPA filter and that it runs on existing batteries. What owners complain about: it is battery-only with no mains option, and it draws hard enough that a small pack empties quickly. Buy it if your shop is already red.
3. CRAFTSMAN CMCV002B — Best Value
The sensible budget option, and its best feature is the one nobody lists first: a 7 foot 8 inch hose. On a two-gallon vacuum, hose length is what determines how often you have to pick the unit up and move it, and a nearly eight-foot hose lets you reach across a whole car interior or under a workbench from one position. It has a HEPA-rated filter, handles wet and dry, and stores the hose and accessories on board. What owners praise: the hose length, the price and that the V20 platform is inexpensive to buy into. What owners complain about: suction is a step below the DEWALT and Milwaukee units, and the plastic feels lighter-duty. The right buy for household and car use.
4. Makita XCV11Z — Best for Fine Dust
The specialist, and the only vacuum here that should be pointed at drywall dust. It carries a true HEPA filter rated to capture 99.97 percent of particles at 0.3 microns, with a sealed body so air cannot bypass it, and a brushless motor that both extends runtime and holds airflow better. Makita quotes up to 57 CFM and 27 inches of water lift, which puts real suction behind the filtration, and it works as a tool-mounted extractor on a sander or a drywall sander. What owners praise: that fine dust genuinely stays in the machine, the brushless runtime and the build. What owners complain about: it is the most expensive here by a wide margin, HEPA filters are costly to replace, and two gallons of fine dust fills quickly. See our fine dust roundup for corded alternatives.
5. RIDGID 3 Gallon 18-Volt — Best Capacity
Three gallons rather than two, which is a bigger deal in practice than on paper: it is fifty percent more debris between trips to the trash can, and small tanks fill astonishingly fast once you are picking up plaster, sawdust or leaves. The 1-7/8 inch locking hose expands to seven feet, so reach is good, and the standard cartridge filter and car nozzle are included. What owners praise: the capacity, the locking hose that does not pop off, and the price on the RIDGID platform. What owners complain about: it is bulkier and heavier to carry, the standard filter is not HEPA, and RIDGID 18V is a smaller platform than the big three. Best for demolition and yard cleanup.
6. DEWALT DCV580H — Best Cordless-Only
The same design as our top pick without the AC circuitry, which makes it lighter and cheaper. That is exactly the right trade if the vacuum lives in a truck, a van or a trailer and will never be near an outlet anyway — you are not paying for a feature you cannot use. Two gallons, wet and dry, washable HEPA-rated filter, onboard accessory storage. What owners praise: lighter than the dual-power version, same suction, lower price. What owners complain about: when the battery dies the job stops, and the same short hose and small tank as the DCV581H. The pure jobsite choice.
What Owners Actually Complain About
The complaint pattern here is extremely consistent and almost entirely predictable from the physics.
“The battery lasts no time at all.” By far the top complaint across every brand, and it is inherent to the category rather than a defect. A vacuum motor is the highest sustained draw of any cordless tool. The realistic fixes are a high-capacity battery, a second battery on the charger, or a model with a mains option. Anyone expecting an hour of running from a 2.0Ah pack will be disappointed. See how long power tool batteries last.
“It blew dust out the back.” The filter is the wrong grade for what is being vacuumed, or it is clogged, or air is bypassing it around a poor seal. Fine drywall and sanding dust needs true HEPA filtration and a sealed body; a standard cartridge filter passes it straight through. Why a shop vac blows dust out the back covers the diagnosis.
“The tank fills after five minutes.” Two gallons is genuinely small. It is the correct size for a portable tool and the wrong size for cleaning up after a project. Match the vac to the job: cordless for spot cleanup, a full-size corded vac for the big mess. What size shop vac you need works through the sizing.
“Suction dropped off.” Almost always a clogged filter rather than a failing motor. Fine dust cakes a pleated filter quickly and airflow collapses. Tapping or rinsing the filter, and using a dust bag for fine material, restores it. A clogged hose is the other common cause.
“It stinks after picking up water.” Water left in the tank, or a paper filter left in during wet pickup, both grow mold within days. Remove the dry filter before wet vacuuming, empty the tank immediately afterwards, and leave it open to dry. See whether a shop vac can pick up water.
How to Choose a Cordless Shop Vac
Start with the battery platform. This is the most bare-tool-friendly category there is. If you own DEWALT, Milwaukee, CRAFTSMAN, RIDGID or Makita batteries, buy the vacuum that fits them — the tool alone usually costs about half what a kit does, and you already have charged packs on the shelf.
Decide what you will vacuum most. General debris, sawdust and car interiors are fine with a standard cartridge filter. Drywall dust, sanding dust, plaster and concrete dust need true HEPA and a sealed body — OSHA's silica rules for construction specify HEPA-filtered dust collection for exactly this reason, or you are simply moving the dust from the floor into the air. This is the decision that most affects which model is right.
Check the hose length, not just the tank size. On a small vacuum, hose length determines how often you move the unit, and a five-foot hose feels short in a car or under a workbench. Seven or eight feet makes a noticeable difference to how usable the tool is.
Assume you will want a bigger battery. Whatever the runtime claim, plan on a high-amp-hour pack. It is the single cheapest upgrade to the experience, and unlike the vacuum it also improves every other tool on the platform.
Do not expect it to replace a corded vac. A 12 or 16 gallon corded shop vac costs less than most of these, holds six times as much and never stops. The cordless one earns its place by being grabbed and used in seconds — which, in practice, means it gets used far more often. Both is the right answer if the budget allows.
The Verdict
Buy the DEWALT DCV581H if you want one cordless shop vac that will not strand you when the battery dies — the mains option is worth the extra weight and cost. Buy the Milwaukee 0880-20 or the CRAFTSMAN CMCV002B if you are already on those platforms and want the cheapest route to a portable vac. If you are cleaning up drywall or sanding dust, spend the money on the Makita XCV11Z and its true HEPA filter, because everything else in this class will put that dust back into the room. And whichever you choose, buy the biggest battery you can. Check price on Amazon →
