DeWalt Vacuum Guide: Cordless Wet/Dry Vacs and Dust Extractor Compared

A quality vacuum doesn't just clean the jobsite up quickly; it also keeps the work area safer, helps teams stay compliant with OSHA dust standards, and protects crews' lungs and tools for years to come. 

DeWalt makes several vacuums built specifically for trade work, and if you're already running 20V MAX batteries, some of them plug right into your existing setup. This guide covers every DeWalt vacuum in the current lineup, from cordless hand vacs, wet/dry canister vacs, and the corded dust extractor, so you can figure out which one makes sense for your work.

Your average home shop vac isn't built for daily jobsite abuse. Consumer vacs typically have weaker motors, cheaper filtration, and plastic housings that don't hold up to constant use and abuse on a job. 

Jobsite vacuums are built with more durable materials, heavier-duty hoses, and, in the case of DeWalt's lineup, filter systems that can actually trap fine silica and lead dust. That's not just a comfort upgrade. Since OSHA started actively enforcing the respirable silica rule (29 CFR 1926.1153), controlling dust at the source has become a compliance issue for contractors working around concrete and masonry.

The DCV501HB is DeWalt's most portable option -- a lightweight handheld vacuum built for quick dry cleanups. It delivers 46 CFM of suction and uses a HEPA filter (model DCV5011H) that captures 99.97% of particles down to 0.3 microns. That makes it useful for cleaning up after drywall sanding, detail work, or any task generating fine dust. It's dry-use only, so it won't handle liquids or wet slurry. But for clearing a work surface, cleaning out a truck cab, or doing a fast sweep on sawdust, it's hard to beat for size and battery compatibility. It's available as a bare tool and as a tool-only kit that includes a battery.

The DCV517B adds a 1/2-gallon tank and wet/dry capability to DeWalt's compact cordless format. It's still small enough to carry in one hand and runs on the same 20V MAX batteries as the rest of the lineup. Think of it as a step between the hand vac and the larger 2-gallon models -- more capacity than the DCV501HB, more packable than a full canister unit. It handles both wet and dry debris, which makes it more versatile for general jobsite use when you don't need a full-size vac. Sold as a bare tool.

The DCV580H is DeWalt's flagship cordless wet/dry vac. It holds 2 gallons, moves 140 CFM of suction, and uses a HEPA-rated filter that captures 99.97% of dust down to 1 micron. The 5-foot crush-resistant hose is built into the unit, and there's onboard storage for the included crevice tool and wide nozzle. 

A blower port lets you reverse the airflow to push debris out of tight spots rather than vacuum it. The DCV580H is the go-to for contractors who want cordless flexibility with enough capacity to handle a full day of cleanup without stopping every few minutes to empty the tank. Sold as a bare tool.

Here's a quick look at all four cordless models together so you can spot the differences at a glance.

General contractors move between sites constantly and deal with all kinds of debris -- drywall dust, wood shavings, concrete particulate, spilled liquids, and plenty of things in between. The DCV581H is probably the best fit here. It's got a 2-gallon tank, HEPA filtration, and the ability to run on battery or plug into an outlet, which means it adapts to wherever you are. On a jobsite without power, run it on battery. At a job trailer or shop with an outlet nearby, plug in and save your charge for your tools.

Concrete and masonry work generates respirable silica dust -- the fine particulate OSHA's silica standard is specifically written to control. If you're cutting, grinding, or core drilling concrete and you're covered under Table 1 of OSHA's silica rule (which applies to most construction masonry operations), you need a HEPA vacuum with enough airflow to keep pace with the tool you're using. The DWV010 is the right call here. Its 155 CFM airflow, 8-gallon tank, and RRP-compliant filtration make it purpose-built for this kind of work. The auto-filter cleaning is a real advantage -- you're not stopping every 15 minutes to manually clean the filter while your crew is waiting.

Painters doing surface prep -- sanding drywall, stripping old coatings, working in older buildings -- need filtration they can rely on. The DCV501HB handles fine drywall dust well for lighter prep work, and its HEPA filter keeps airborne particles out of your breathing zone. For any jobs covered under the EPA RRP rule -- lead paint in pre-1978 homes -- the DWV010 is the compliant tool. The compact size of the DCV501HB also makes it easy to run alongside a sander without adding another cord to manage.

Finish carpenters and woodworkers deal primarily with fine wood dust -- the kind that settles on finished surfaces and gets into everything. The DCV580H is well-suited for shop and site work: the 2-gallon tank means fewer trips to empty it, and the HEPA filter keeps the air cleaner throughout the workday. The blower port is useful for clearing chips from tight spots or blowing dust off your tools. If your shop has reliable power, the DCV581H's AC/DC capability lets you plug in and leave your batteries on the charger for when you actually need them on a job.

HEPA stands for High Efficiency Particulate Air. A true HEPA filter captures 99.97% of airborne particles at 0.3 microns. For trade work, that distinction matters because the particles that cause long-term lung damage -- respirable silica, lead dust, fine wood particles -- are often far smaller than what a standard filter can stop. 

Standard filters in consumer shop vacs typically handle particles down to around 5 microns, which means a significant portion of the most hazardous dust passes right through and gets recirculated into the air you're breathing. The HEPA filters in the DCV501HB, DCV580H, DCV581H, and DWV010 all meet or exceed the 0.3-micron standard. For work involving drywall, concrete, hardwoods, or older building materials, a HEPA-equipped vac isn't an upgrade -- it's the right tool for the work.

Cordless vacuums give you freedom of movement and work anywhere -- but you're limited by battery life. The DCV580H and DCV581H both run well on a charged 20V MAX battery, but heavy continuous use during a full shift will cycle through batteries. If that's a concern, the DCV581H's dual-power capability is the practical solution: run on battery when you need to move, plug in when there's an outlet nearby. The DWV010 is corded-only, which requires an outlet, but it also delivers the most airflow (155 CFM) and the largest tank (8 gallons) in the lineup. 

For sustained dust extraction during heavy cutting or grinding sessions, corded power is the more practical choice. For general mobility and between-task cleanup, cordless wins. The DCV581H handles both scenarios as well as any single vacuum can.

All four cordless vacuums in DeWalt's lineup run on 20V MAX batteries, which means they're compatible with the entire 20V MAX platform -- the same batteries that power DeWalt's drills, circular saws, oscillating tools, and hundreds of other tools. 

If you're already running a 20V MAX setup, adding one of these vacuums doesn't require a new battery purchase. A compact 1.5Ah or 2.0Ah battery is fine for lighter use, but if you're running the vac for extended periods, a 4.0Ah or 5.0Ah battery will give you significantly more runtime between charges. The DCV581H also accepts 18V batteries from the older DeWalt platform, which is a bonus if you've still got 18V packs on your shelf.

DeWalt's vacuum lineup covers a lot of ground -- from a sub-3-pound handheld that fits in a work bag to an 8-gallon HEPA dust extractor built for sustained RRP-compliant cleanup. The right choice comes down to where you work, what you're cleaning up, and whether regulatory compliance is part of the picture on your jobs. 

If you're already running 20V MAX tools, any of the cordless models drops right into your existing battery setup with no extra investment. If you're doing masonry, concrete cutting, or renovation work in pre-1978 buildings, the DWV010 is the tool that keeps you on the right side of OSHA's silica rule and the EPA's lead paint regulations. DeWalt's World of Concrete product announcement specifically highlights OSHA compliance as a design priority -- the automatic filter cleaning, HEPA certification, and high-flow 15-amp motor in the DWV010 are all built around what compliance actually demands on a job, not just what sounds good on a spec sheet. Start with your work conditions, match the model to what the job requires, and you'll end up with a vac that earns its keep every shift.
