The DEWALT DCV581H 20V MAX Cordless/Corded Wet-Dry Vacuum is a portable wet/dry shop vacuum built for jobsite cleanup, service calls, punch-list work, and quick wet pickup without dragging out a full-size vac. This is a wet/dry shop vacuum designed for jobsite cleanup and small-volume wet pickup. Model Number: DCV581H. If you already run DEWALT 20V MAX tools, this vacuum makes a lot of sense because it can work off the same battery platform, and when outlet power is available you can plug it in and save your battery for drills, saws, or impacts.

The big draw here is flexibility. DEWALT gave the DCV581H both cordless and corded operation, so you can carry it anywhere for fast cleanup or set it up on AC power when the work stays in one area. That matters more than it sounds. On a service truck, remodel job, or finish work punch-out, you are not always close to power. On the other hand, when you are cleaning up around a bench, utility room, or mechanical space, plugging in means you get the convenience of a compact vacuum without worrying about runtime.

For actual performance, the numbers are solid for a vacuum in this size class. The 2-gallon tank keeps the unit compact and easy to carry, but it still has enough capacity for everyday debris and small wet messes. Supplementary data lists up to 140 CFM of airflow and 52 inches of water lift, which explains why this unit is often called out for cleaning clogged pipes, emptying toilet water, and picking up heavier wet debris that smaller handheld vacs struggle with. It is not a replacement for a large rolling extractor, but it is a practical middle ground between tiny spot vacs and full-size shop vacs.

The hose setup is built for real use, not showroom photos. You get a fully integrated 5 ft. heavy-duty hose with a 1-1/4 in. diameter, which is a good size for balancing airflow, flexibility, and portability. Because the hose stores right on the tool, the DCV581H is easier to keep ready in a van, trailer, or gang box. DEWALT also includes both a crevice tool and a wide nozzle tool, so you can move from tight corners and cabinet bases to broader floor or bench cleanup without hunting for attachments.

Filter maintenance is another strong point. The included wet/dry filter is washable and reusable, and supplementary data identifies it as a Gore wet/dry HEPA filter rated to trap 99.97% of dust at 0.3 microns. In plain terms, that means less throwaway filter cost and easier maintenance for regular cleanup work. When a vacuum is quick to clean and put back in service, it gets used more often. That matters on jobs where fine dust and small debris build up fast.

Jobsite practicality is clearly part of the design. The plastic canister keeps weight down to about 11.06 lbs, and the top-mounted handle makes it easy to carry one-handed. Built-in storage compartments help keep the hose and accessories with the vacuum instead of rattling loose in the truck. Supplementary data also notes a blower port, which gives you another way to clear fine debris from small spaces, patios, or around equipment when vacuuming is not the quickest option.

System-wise, this vacuum fits neatly into the DEWALT 20V MAX platform. It is sold as a tool only, so batteries and charger are not included. That is good news for current DEWALT users who already have packs on hand and want a cleanup tool that works within the same cordless system. If you are not already on that platform, factor in the cost of a battery and charger, or plan to use it mainly on AC power.

Who should buy it? This vacuum makes the most sense for remodelers, plumbers, HVAC techs, electricians, punch-out crews, property maintenance, and serious DIY users who need something portable, durable, and useful for both dry debris and small wet cleanup. If you need a compact shop vacuum that can ride in the truck, work off a battery, and still plug in when you have power nearby, the DCV581H hits a very practical sweet spot.

Small Vac, Smart Setup

The DEWALT DCV581H 20V MAX Cordless/Corded Wet-Dry Vacuum is the kind of cleanup tool that earns its spot in the truck because it is compact, versatile, and actually useful for both dry debris and wet messes.

• Who it's for: DEWALT 20V MAX users, service techs, remodelers, plumbers, and anyone who needs a portable jobsite vacuum instead of a full-size shop vac.
• Why it stands out: The corded-or-cordless design is the real win here. Add in the 2-gallon tank, integrated 5 ft. hose, washable HEPA-rated filter, and included nozzles, and you get a vacuum that is set up for actual work instead of occasional cleanup.
• Worth knowing: This is a bare tool, so no battery or charger in the box. And while the suction is strong for a compact vacuum, it is still a small portable unit, not a replacement for a big extractor on heavy demolition cleanup.

• Can this vacuum run on both battery and corded power? Yes. The DCV581H can operate on a DEWALT 20V MAX battery or from an AC outlet.
• Is this a wet/dry vacuum? Yes. It is designed to pick up both wet and dry debris and has a 2-gallon tank.
• Is the filter reusable? Yes. The filter is washable and reusable, and supplementary data identifies it as a wet/dry HEPA filter.
• Does this come with a battery and charger? No. This is a tool-only bare unit, so the battery and charger are sold separately.
