Corded vs Cordless Shop Vacuum: Which One Should You Buy?

Side by side

Corded vs cordless shop vacuum: runtime is the real split

Runtime is where the two sides genuinely differ, and only one side of this comparison states a number. The DEWALT DCV580H lists 25 minutes of runtime; the DCV517B handheld states no runtime at all. Both are bare-tool-only, so the real runtime also depends on the 20V MAX pack you already own, which the listings do not cover. A corded vac has no such question: it runs while it is plugged in, which is the whole argument for corded when the cleanup is big.

Do not read more into the numbers than they say. The 25-minute figure describes the DCV580H only, not cordless vacs as a class, and there is no corded listing here to compare against. If your jobs regularly run longer than a battery pack lasts, that alone points to corded; if they are quick hits around the garage and the car, cordless wins on convenience.

Tank size and portability

The two cordless examples show the cordless range: a 2-gallon canister at 8 pounds against a 1/2-gallon handheld at 4.5 pounds. The canister suits garage floors and bigger messes; the handheld suits car interiors, workbenches and spot cleaning. The two examples top out at 2 gallons; for a bigger tank, look at corded models.

Filtration

Filtration is the one spec where both listings agree: each states a HEPA filter that traps 99.97% of dust at 0.3 microns, and both filters are washable. The DCV580H uses a HEPA-rated cartridge filter; the DCV517B uses a Gore HEPA wet/dry filter. Neither listing states a safety certification, so both score zero on safety.

Noise: check the stated figures

Noise is the one spec where the two listings look like different species. The DCV517B listing states 80 db, while the DCV580H listing states 31 db. That is a wide gap on paper, and it is worth pausing on: two cordless vacuums from the same brand, one stated at a level you would want hearing protection near and one at a quiet hum. Treat both figures as listing claims rather than something you can verify here. If you share walls, work early mornings or keep the garage attached to the house, let the 80 db figure on the handheld push you toward the canister, or toward confirming the 31 db claim before you buy.

Hoses, nozzles and how you actually clean

Attachments decide what the vacuum can reach. The DCV580H ships with a 5 ft heavy-duty crush-resistant hose at 1-1/4 in diameter, a wide nozzle tool and a crevice tool that is Airlock compatible, plus on-board accessory storage and a mounted handle. The DCV517B takes a different route: dual clean-up modes, a front utility nozzle for direct pickup and an extendable rubber hose the listing calls heavy-duty and flexible, with a large on/off switch you can hit with one hand. For car interiors and workbenches, the handheld’s direct nozzle and one-hand switch suit quick grabs. For garage floors and around the shop, the canister’s 5 ft hose and stored tools cover more ground without dragging the vac along.

Speeds differ too, and they are worth a look. The DCV517B lists 2 speeds and 2 power levels, so you can step up for heavier debris and step down for light dust. The DCV580H lists 1 speed. More speeds do not make a stronger motor, but they do give the handheld a bit of control the canister lacks.

The bare-tool catch: batteries not included

Both examples are sold as bare-tool-only or tool-only: no battery, no charger. That is fine if you already own 20V MAX packs, and a real added cost if you do not. A cordless vacuum that needs a pack you do not own is a two-part purchase, and the listings do not price the pack. Corded vacs dodge this entirely: the price on the box is the price of a working vacuum. When you compare cordless against corded, add the pack to the cordless side of the mental math if your toolbox is empty.

There is also the platform question. Both examples run on 20V MAX packs, so buying one ties your next cordless tool purchase to the same platform. That is a feature if you are already on it, and a commitment if you are not. A corded vac asks for nothing but an outlet.

Wet pickup, filters and upkeep

Both listings state wet and dry pickup, and both filters are washable, which keeps running costs down. The DCV517B uses a Gore HEPA wet/dry filter you clean by tapping or a water rinse. The DCV580H uses a HEPA-rated cartridge filter that is washable and reusable and, per the listing, easily accessible. For wet jobs with real volume, the DCV580H is the one the listing positions for the task: its bullets say the 2-gallon tank provides enough storage to empty a toilet or a clogged pipe, and the spec table claims a maximum suction of 31 feet. The handheld’s 1/2 gallon is for spills and spots, not volume.

Upkeep is simple on both. Rinse or tap the filter, empty the tank, and the heavy-duty latch on the handheld’s 1/2-gallon tank makes that part easy. Both listings state a 3 year limited warranty, which is worth having on a tool that inhales dust for a living.

Which example for which job

Match the vac to the mess. For car interiors, detailing and quick bench cleanups, the DCV517B handheld at 4.5 pounds and 8.44 x 6.38 x 17.69 in is the grab-and-go choice, with its 2 speeds to step up for heavier debris. For garage floors, bigger dry messes and wet work, the DCV580H canister at 8 pounds and 17.25 x 12.31 x 13.12 in brings the 2-gallon tank, the 5 ft hose and the stated 25 minutes of runtime. If your jobs regularly run longer than one battery lasts, or need a bigger tank than 2 gallons, that is the signal to shop the corded side instead.

Frequently Asked Questions

How long does a cordless shop vacuum run?

Of the two listings here, only the DCV580H states a figure: 25 minutes. The DCV517B states no runtime. Both are bare-tool-only, so the battery you own also decides the real number.

Are the batteries included?

No. Both examples are sold as tool-only or bare-tool-only, with the battery and charger sold separately. Factor a 20V MAX pack into the cost if you do not own one.

Can these pick up water?

Yes. Both listings state wet and dry pickup, and both filters are washable.

What does the HEPA filter do?

Both listings state their HEPA filter traps 99.97% of dust at 0.3 microns. Both filters are washable, so you rinse and reuse them instead of buying replacements, per the listings.

Corded or cordless for a garage?

Cordless for portability and quick jobs: no cord to drag around the car. Corded for unlimited runtime and larger tanks. The two examples here cover the cordless side from a 1/2-gallon handheld to a 2-gallon canister.
