Editorial Product Review:Amazon.com:Light, portable, versatile, and powerful, DeWalt's new little vac is a great invention. We love that it's powered by a 12- to 18-volt battery, allowing for use when the power's off or you're too far from an outlet, and that you can also plug it in for continuous use. If you're a DeWalt fan, it's likely you already have the 12- to 18-volt batteries and the charger, so the fact that this is sold without those won't affect you. But that's a change we'd like to see DeWalt make. Other than that, it couldn't be better. The five-foot hose is flexible, and the cleaning tools fit on board. The suction's impressive, whether on AC or DC power. Unlike other wet-dry vacs, you don't have to change out the filter innards when switching from wet to dry, and we just love that. Just rinse it off to clean it. Its high-efficiency filter is listed at trapping 99.7 percent of dust, and in our book, less dust in the air is a good thing. When you're wet-vacuuming, just empty the tank through the drain port. It's light as a feather, super-portable, and plenty powerful.

It makes sense
I bought the DC500 vaccum nearly 2 years ago and I have been using it a lot. It is not very powerful compared to a large shop-vac but extremely convenient and that's why I use it so much.
I recomend it if you have other Dewalt tols and batteries and if you're willing to accept trade-offs: it is not perfect but works well.
I use it corded when cutting or sanding and it has plenty of power to suck sawdust. i use it cordless when I need something portable (clean car). The battery drains in about 15 minutes. On one hand a quick drain is a problem but it also shows that it has a high power. You can't have you cake and eat it too so I figure it is a god sign that the battery drains quickly.
The power is the same corded/cordless.
The filter is great and durable (i am still using the same one). there is no bags needed, just clean the filter!
A word of caution: it is not weather-proof, don't let water get inside from the top. There is a sensitive electronic board unprotected. And don't remove the filter when vaccuming water (my neighbour killed the first one doing that).
Improvement suggestion: weather seal the electronic board; perfect the attachement (they sometimes fall off), reduce noise.

Weak!
I needed a powerful cordless wet/dry vac so I did a lot of research, ended up trusting the Amazon reviews for this product, and finally bought it from Amazon. I was really disappointed when I unpacked it and tried it: it was extremely weak, whether plugged in or on battery power. Luckily, Amazon accepted it as defective, and refunded me my total purchase price. That's why I but a lot of stuff from Amazon, they're fair and honest with returns. I'd be afraid to buy another one, and find out that the weak performance is due to poor design and a weak motor.

Too bad this vac doesn't suck...
The suction is miserable on this vacuum. The build quality is typical DeWalt and the battery option is nice, but for $100 it should suck more. Really.

Overall good, could use more power
This is NOT a full-blown shop vac. If you're looking for that kind of power, you're going to be disappointed. It has more power than other portable vacs, much more than a dustbuster type vac.
For light vacuuming around the shop or for portable use, like in the car, this vacuum works well. I like the fact that you can plug it in when you have a job that would take too long for the batteries to last. Overall, it's a good portable vacuum, although it's a little expensive for what it is.
