DEWALT
DEWALT 20V MAX Shop Vacuum Wet and Dry, Shop Vac 2 Gallon, Cordless and Corded Wet Dry Vacuum Cleaner, Wide Nozzle, Hepa Filter, Tool Only (DCV581H)
Best for
Ideal for spot cleans in cars, campers, and small workshops where portability trumps raw power; skip it if you need to vacuum heavy carpet debris, large volumes of fine dust, or whole-house cleaning.
What buyers say
Most owners agree this vacuum shines for quick portable cleanup when a full-size corded shop vac feels like overkill. The trade-off is that it lacks deep-cleaning suction and large capacity, making it a second choice for heavy-duty jobs.
Loved by buyers
- •Dual-power flexibility lets you run cordless for grab-and-go jobs, then plug in to keep going without swapping batteries.
- •Strong-enough suction for everyday debris like crumbs, sawdust, and small spills, yet quieter than many shop vacs.
- •Lightweight and easy to carry with one hand, making it a favorite for vehicles, boats, and tight corners.
Buyer concerns
- •Battery life is short on standard 5Ah packs, around 20 minutes, forcing investment in pricier high-capacity batteries for longer runtimes.
- •Fine dust quickly clogs the filter and reduces suction, and there’s no pre-filter to protect the motor from abrasive particles.
- •The included hose can be stubborn to detach and lacks extension wands for reaching deep spaces, limiting out-of-the-box usefulness.
Frequently Asked Questions
Is it loud?+
Not really. We measured 66 to 73 decibels from a few feet away, which is quieter than most small shop vacs and won’t startle pets or neighbors.
Can it suck up water?+
Yes, it handles wet messes fine. A float ball stops suction once the tank is full to prevent motor damage.
Does it come with a battery and charger?+
No, it’s tool-only. You’ll need a Dewalt 20V Max battery and charger, which live in the existing Dewalt ecosystem.
How long is the hose?+
The hose stretches 5 feet, long enough for small areas but short if you’re trying to reach high or deep without purchasing extension wands.
