What experts liked
One standout feature, though, is its rechargeable battery. This means you don't have to be near a power source to use the vacuum.
- Top Ten Reviews
The crevice tool stores nicely in the handle and the wide nozzle clips to the front of the unit.
- Pro Tool Reviews
On-board hose comes with useful accessories – crevice nozzle and wide nozzle.

Rugged and versatile. Reliable suction w/HEPA filtration.
- BestReviews
It is very sturdy and durable unit – casing is much stronger than casing of many other, larger and more expensive vacuums.
- Pick A Vacuum Cleaner
DeWalt DCV581H comes with wet-dry true HEPA air filter, which is capable of filtering out 99.97% of 0.3 microns and larger particles from the sucked air.
- Uprights With Hoses
DeWalt added on-board storage to the vacuum to make it easy to keep accessories neatly organized and ready to use when needed. Adding to this small wet/dry vac's popularity is the fact that it isn't as big as a standard unit.
- Power Tools Zone
The filter traps 99.97 percent of dust which makes this vac fit to use for fine dust like drywall dust since it will not blow particles into the air like some vacuums do.
- Vac Advice
What experts didn't like
It's also the slowest at wet cleanup. It took the DeWalt over 12 seconds to suction 2 gallons of water. That was the worst of those we tested.
- Top Ten Reviews
You’re not going to be able to do really heavy work with this vac, and I wouldn’t hook it up to anything where you were staking your LRRP credentials on its dust-collecting prowess.
- Pro Tool Reviews
Noisy; hearing protection is recommended.
- Tool Guyd

Pricey, and the battery and charger must purchased separately.
- BestReviews
It is not the lightest vacuum cleaner – it weighs around 9.1 pounds (around 4.1 kg) and when in use, it is held by one hand (or it is on the floor), while other hand cleans the area with cleaning hose.
- Pick A Vacuum Cleaner
When the battery is plugged into the unit and the power cord is also plugged in, DeWalt DCV581H doesn't charge the battery - to charge the battery, separate battery charger must be used.
- Uprights With Hoses
Won't pick up nails or screws.
- Power Tools Zone
​You have to buy the battery and charger separately and that becomes expensive.
