In the DeWalt DCV580H vs DCV581H comparison, choose the DCV581H for corded or battery power and the DCV580H for battery-only cleanup. Both are compact 2-gallon wet/dry vacs with 5 ft hoses, so the power source is the clearest difference.
The DCV581H adds the option to plug in when a cord is practical. The DCV580H keeps the choice simple if you want to run the vac from a DeWalt 20V MAX battery.
DeWalt DCV580H vs DCV581H: which power option fits?
The DCV581H runs from a cord or a DeWalt 20V MAX battery; the DCV580H runs from a battery. That difference matters when you plan where the vac will be used and whether you have a compatible battery ready.
Choose the DCV581H if cleanup moves between places with outlet access and places where a cord would get in the way. It gives you the flexibility to use either power source, though you still need to supply the battery and charger if you want cordless use.
Choose the DCV580H if you want a cordless vac and already have, or plan to get, a DeWalt 20V MAX battery. If battery power is the plan every time, the DCV581H's cord option may not add much value to your routine.
Neither model comes with a battery or charger. Include those in your setup if you do not already have compatible power.
What do the two DeWalt vacs have in common?
Both DeWalt models have a 2-gallon tank, a 5 ft hose and a washable, reusable filter. Each comes with a wide nozzle, a crevice tool and on-board accessory storage.
That shared setup suits quick pickups in a garage, vehicle or work area where a large tank would be cumbersome. Use the wide nozzle across open surfaces and switch to the crevice tool for narrow gaps.
The DCV580H filter is HEPA rated and traps 99.97% of particles at 0.3 microns. The DCV581H comes with a Gore wet/dry HEPA filter.
Those filter descriptions differ. Neither model changes the main buying choice: their power options.
Who should buy the DCV581H?
The DCV581H suits you if you want a small wet/dry vac with a choice of corded or battery power. It is the more flexible fit when outlet access varies between cleanup spots.
A cord can make sense when you are working near an outlet and want to avoid relying on battery runtime. Battery operation can help when you need to move around without managing a cord.
The DCV581H gives you both approaches in the same vac.
Skip it if you know you will only use battery power and do not need the cord option. The DCV580H covers that use more directly, with the same tank capacity and hose length.
Also skip either DeWalt if your regular jobs involve collecting more than a small wet or dry mess at a time. A 2-gallon tank limits how much material you can collect before emptying.
Who should buy the DCV580H?
The DCV580H suits you if you want cordless wet or dry cleanup and can supply a DeWalt 20V MAX battery. Its power setup fits short jobs where freedom from a cord is the priority.
The included wide nozzle and crevice tool cover open areas and tighter spaces. On-board storage helps keep the hose and accessories together when you carry the vac between work areas.
Skip the DCV580H if you want the option to plug in for longer cleanup sessions. It has no corded power option, so you will need a compatible battery for every job.

Are these compact vacs right for your cleanup?
Either DeWalt can fit small wet and dry pickups, but a 2-gallon tank is not meant for large-volume cleanup. Think about how often you are willing to stop and empty it before choosing a compact vac.
The tank size makes sense for limited messes and spot cleanup. For a large amount of debris, repeated emptying can slow the job and interrupt the work.
If your main tasks involve floors across a garage or home, compare larger-capacity options in our wet/dry vac buying guide.
The matching 5 ft hoses give the DeWalt models the same reach. Measure the distance from where you can safely place the vac to the farthest area you need to clean.
If 5 ft feels short for that layout, the Craftsman CMCV002B has a 7 ft 8 in hose and the same 2-gallon capacity.
How should you set up and care for a DeWalt wet/dry vac?
Start by matching the filter and setup to the kind of pickup you plan to do, then follow the manual for wet and dry use. Keep the hose and accessories connected and stored as intended for the job.
Before starting, check that the filter is seated correctly and the hose is clear. A loose filter or blocked hose can interfere with pickup, while using a wet/dry vac in a way the manual does not allow can damage the vac or create a mess.
For dry debris, use the filter setup specified in the manual. After wet pickup, empty and clean the tank as directed.
Let washable parts dry fully before storing them. The filters on both DeWalt models are washable and reusable.
If suction drops, check the hose for a blockage and make sure the filter is clean and properly installed. Our guide to why a shop vac loses suction walks through common causes.
What mistakes should you avoid when choosing between them?
The main buying mistake is paying attention to the model name before checking the power you actually need. Confirm whether you want corded use, battery use or both, then check whether the tank and hose suit your work.
Do not assume the words “20V MAX” mean a battery and charger are included. Both DeWalt models are sold without them, so add compatible power to your plan if you do not already own it.
Do not buy either expecting a bigger tank or longer hose than the other. Both have the same 2-gallon capacity and 5 ft hose.
If either limit conflicts with your usual tasks, step up to a larger or longer-reach option.
Finally, do not treat HEPA wording as a substitute for correct filter care. Keep the filter clean and use it as directed for the pickup at hand.
DeWalt DCV580H vs DCV581H: which one should you choose?
Choose the DCV581H if you want the option to run on a cord or a DeWalt 20V MAX battery; choose the DCV580H if battery-only operation fits your work. Both offer the same compact tank size and hose reach.
The DCV581H is the stronger fit for mixed work locations where outlet access changes. The DCV580H is the straightforward choice for portable cleanup when you have compatible battery power ready.
Choose the Craftsman CMCV002B if a longer hose matters more than a cord option, and use our Shop-Vac vs Craftsman guide to compare that alternative.
