Best Cordless Shop Vacs

1. How We Chose

We built this list from manufacturer specifications and retailer listings, not from a lab test. Every airflow, suction and runtime figure below is attributed to Makita, Milwaukee, Ryobi, RIDGID, DeWalt or Craftsman, or to the retailer that published it, and where two sources disagree we say so rather than picking the more flattering number. That matters more for cordless vacs than for most tools, because battery vac specs are often quoted at the highest power setting on the largest battery the brand sells.

We started from one rule: the right cordless shop vac is almost always the one that runs on batteries you already own. A battery vac on a platform you do not use is a corded vac with a much higher price, because you have to buy packs and a charger before it does anything. So the list covers one strong option on each major platform rather than ranking seven machines from the same brand.

Within each platform we looked at four things in order. Airflow in CFM, because that decides whether debris actually travels up the hose. Hose diameter, because a 1-1/4 inch hose clogs on wood chips and leaves no matter how strong the motor is. Tank size, because a 2 gallon tank is a cleanup tool and a 6 or 9 gallon tank is a water-extraction tool. And the filter, because a vac that blows fine dust back into the room is worse than no vac for drywall and sanding work.

We also checked what each brand says about runtime, and which battery that figure assumes. A runtime quoted on a 12Ah pack is not the runtime you get on the 4Ah pack that came in your drill kit, and we flag that wherever it applies. If you are still deciding whether you need a battery vac at all, our main shop vac guide covers the corded machines that still win on raw power per dollar.

2. Can a Cordless Shop Vac Replace a Corded One?

For most homeowners, not entirely, and it helps to be honest about that before spending several hundred dollars. A corded shop vac runs as long as you want, and a mid-size corded unit is cheap. A cordless vac runs as long as the battery lasts, and a large-capacity pack can cost as much as the vac itself. The question is not which one is more powerful but which jobs you actually do.

Cordless wins where the cord is the problem. Cleaning out a car in the driveway, vacuuming sawdust at the end of a job on a site with no power yet, chasing a spill in the basement, or tidying a workbench in the time it takes to find an extension cord. These are short, frequent jobs, and the vac that is always in reach gets used. The existing pick on our shop vac roundup makes the same point: owners use the cordless vac far more often simply because there is no cord to deal with.

Corded still wins for long jobs and heavy material. Emptying a flooded floor, clearing a garage full of leaves, or running a vac as dust extraction behind a sander for an hour will drain any battery quickly. If your main use is one of those, buy a corded vac first and a compact cordless one second, or choose a battery vac that takes two packs.

There is a middle path. DeWalt's DCV581H runs on battery or a wall outlet, and RIDGID's and Makita's two-bay designs double the battery capacity you can carry. If you want one machine to do most things, those designs remove the biggest weakness of a battery vac.

3. Our 7 Picks

These picks are researched from manufacturer specifications and retailer listings, not lab-tested; every figure is attributed to its source. They cover one strong option per major battery platform, from a full-size 6 or 9 gallon vac down to compact HEPA and budget units.

4. CFM, Water Lift and Why Peak HP Disappears

Corded shop vacs are still sold on peak horsepower, a figure that describes the electrical draw when the motor stalls and has little to do with cleaning. Cordless vacs mostly skip it, which is a small mercy. What you will see instead are two numbers: airflow in cubic feet per minute, and sealed suction, often called water lift and measured in inches.

Airflow is how much air the vac moves with an open hose, and it decides whether loose debris travels up the hose and into the drum. Water lift is how hard the vac pulls against a sealed opening, and it decides whether the vac can lift water, pull debris out of carpet or pull through a clogged filter. Our guide to CFM versus horsepower explains the physics in more detail, but the short version is that you want both, and for general garage cleanup airflow matters most.

On the listed numbers, the spread here is wide. Makita's 40V XGT vac is rated at 148 CFM. The 18V Milwaukee and Ryobi 6 gallon units are listed at 87 and 80 CFM, and RIDGID's 9 gallon at 82 CFM. The compact 2 gallon machines sit between 31 and 57 CFM. Those are manufacturer and retailer figures, not measurements, and brands do not all test the same way, so read small differences as noise and large ones as real.

Be wary when a listing swaps the two numbers. We found one retailer listing the Milwaukee at 60 CFM and 87 inches of water lift while others list 87 CFM and 60 inches of suction, and a Milwaukee 2 gallon listing that gave the water lift figure as the CFM. When a spec looks odd, check the brand's own page before you rely on it.

5. Runtime and Battery Math

Runtime is the number that disappoints cordless vac buyers most, and it is almost always because the published figure assumes a battery you do not have. Milwaukee quotes up to 31 minutes for the M18 FUEL 6 Gallon in Max Power mode on an HD12.0 pack. Makita quotes up to 60 minutes for the XCV11Z on a 5.0Ah pack. Milwaukee quotes 30 or more minutes for its M18 2 gallon vac on a 9.0Ah pack. Those are useful figures, but they are best cases.

A simple way to estimate your own runtime is to scale by amp-hours. If a vac is rated for 31 minutes on a 12Ah pack, a 6Ah pack on the same platform will give you roughly half that, and a 4Ah pack roughly a third. The real number will be a little worse, because smaller packs sag more under heavy load and many vacs run the motor harder than a drill does. Cold garages also cut lithium-ion capacity, which matters if you plan to vacuum snow melt off a winter floor.

Two practical fixes help more than chasing a bigger battery. First, use the low setting where the vac has one. Ryobi's two-speed motor and Makita's variable power dial exist precisely to trade suction for runtime on dust and light debris. Second, consider a two-bay vac. The RIDGID 9 gallon and Makita XGT units both take a second battery, which roughly doubles the energy available without buying a giant pack.

If you rely on your batteries for other tools, think about the knock-on effect. A vac that drains your only high-capacity pack will leave your circular saw idle. Our explainer on cordless tool batteries covers how amp-hours, voltage and high-output cells affect what you can run.

6. Tank Size: Smaller Than You Think

Tank size on a cordless vac is less important than it looks, because the battery usually runs out before the drum fills with dry debris. A 2 gallon tank holds a surprising amount of sawdust and the contents of a car interior. Where tank size really matters is water. A gallon of water weighs a little over eight pounds, so a full 6 gallon drum is heavy, and a full 9 gallon drum is a two-hand lift.

For dry cleanup, a compact 2 gallon vac like the Makita XCV11Z or the CRAFTSMAN CMCV002B is easier to carry up a ladder, into a car or across a job site, and you will use it more often because of that. For wet cleanup, such as a leaking water heater or a basement drain backing up, the 6 and 9 gallon units are the ones that actually help, because you are not stopping every few minutes to empty a small tank.

Check how the vac empties. A drum you can tip into a floor drain or out a door is fine for water; a small tank with a tight lid is fiddly. If water is the main job, also check whether the vac uses a foam sleeve or needs the dry filter removed for wet pickup, because running a paper filter wet ruins it.

If you are not sure how big a vac you need at all, our guide to what size shop vac you need walks through tank size by job. For most battery vac buyers, the answer is the smallest tank that handles your wettest likely job.

7. Hose Diameter and Filters

The hose is the most underrated spec on any shop vac. A 1-7/8 inch hose passes wood chips, leaves and drywall scraps that will bridge and clog in a 1-1/4 inch hose almost immediately. The Milwaukee, Ryobi and RIDGID large vacs all use 1-7/8 inch hoses, which is a big part of why they are the ones to buy for garage and yard debris. The compact Makita, DeWalt and Craftsman units use smaller hoses, which concentrate suction well for fine dust and connect more easily to power tool dust ports, but they are poor at bulky material.

Hose length matters too. A 9 foot hose on the Milwaukee lets you leave the vac on the floor and reach a workbench; the 5 foot hose on the DeWalt means carrying the vac with you. Neither is wrong, but think about how you will actually use it.

Filters decide what happens to fine dust. A standard cartridge filter catches visible debris but passes the finest particles straight back into the air, which is exactly the dust that matters for drywall, sanding and concrete work. A true HEPA filter is rated to capture 99.97 percent of particles at 0.3 microns. Makita rates the XCV11Z's filter to that standard. Craftsman describes its filter as HEPA rated at 99.7 percent, and DeWalt listings disagree on whether its filter is rated at 0.3 microns or 1 micron. Read the actual rating, not the word HEPA on the box.

If you are cutting or grinding concrete, or doing regular sanding indoors, a cordless vac with a proper HEPA filter is a step up, but a dedicated dust extractor is the better tool. Our comparison of a shop vac versus a dust extractor explains where the line falls.

8. Pick the Platform You Already Own

Because the battery is the expensive part, the platform decision usually makes itself. If you own Milwaukee M18, look at the M18 FUEL 6 Gallon first, or Milwaukee's M18 2 gallon if you only need a compact vac. If you own Ryobi ONE+, the PCL735 is the obvious pick and the cheapest full-size cordless vac here. RIDGID 18V owners get the biggest tank. DeWalt 20V MAX owners get the battery-or-corded DCV581H. Makita owners choose between the 18V LXT XCV11Z and the much more powerful 40V XGT machines.

If you do not own a platform yet, a cordless shop vac is a poor reason to choose one. The vac is a supporting tool, and the drill, impact driver and saws you buy will define which platform suits you. Our best cordless tool brand guide covers that decision, and our head-to-heads such as Milwaukee vs Makita, Milwaukee vs DeWalt and DeWalt vs Makita go platform by platform.

Makita deserves a specific warning. Its 18V LXT and 40V XGT batteries are not interchangeable, so the XGT vac only makes sense if you already run XGT tools. Makita does sell an adaptor that lets XGT chargers charge LXT packs, but that does not let LXT batteries power XGT tools.

Avoid third-party battery adapters that let one brand's packs run another brand's vac. They bypass the communication between the pack and the tool that protects both from overheating and over-discharge, and every major brand says they void the warranty.

9. Care, Storage and Making Batteries Last

A cordless vac lasts longer with a little care, and most of it is about the filter and the battery. Tap the filter clean after dusty jobs, because a loaded filter chokes airflow long before the tank is full and makes the motor work harder, which drains the battery faster. On HEPA filters, follow the maker's cleaning guidance; some are washable and some are not.

Never put away a vac with water in the tank. Empty it, wipe it out and leave the lid off to dry, or you will open it next month to a smell that does not come out. If you vacuum water, make sure the right filter or foam sleeve is fitted before you start, because a wet paper filter is ruined and can let water reach the motor.

Look after the batteries. Lithium-ion packs prefer to be stored partly charged in a cool, dry place, not left on the charger in a hot garage all summer or in a freezing shed all winter. A pack that is too cold may also refuse to charge until it warms up, which is a protection feature, not a fault.

Finally, check warranty terms before you need them. Ryobi lists a 3-year limited warranty on the PCL735. Milwaukee, Makita, DeWalt, RIDGID and Craftsman each have their own tool and battery terms, and some require registration. Keeping the receipt and registering the vac takes five minutes and turns a failure into a warranty claim.
