This thing is a beast!
I'm a bit of a DeWalt fan and own many of their corded and cordless products, so this was definitely on the list of items I wanted to own.
Pros:
-Its cordless AND corded!!
-Its not as heavy as it might look, my fiance even uses it without complaining!
-This thing can suck a golf ball through a water hose without its lipstick transferring
-The accessories fit the hose snuggly and don't fall off like other shop vacs
-Easy to clean, just dump the black plastic bottom/bucket and shake off the twist-lock dust filter
-Compact size but big enough to handle REAL tasks
-My batteries are from a drill/impact set and roughly 4 years old yet still last for over 25min vacuum time
-PLENTY of power while using it as a CORDLESS unit
-It sounds a bit more powerful while using CORDED power (higher overall operational frequency), but do not have an effective means of measuring this
-I beat the s*** out of my tools and have shown this unit zero mercy and can vouch for its overall toughness/construction. I do fear that I will eventually break the hose (due to its flexible nature) and will probably trip up and step on the other accessories (this is how all of my vacuum accessories reach their demise).
-5 stars would purchase again!!
Cons:
-The d@mn exhaust for this thing is on the wrong side for a right hand dominant individual. I hold/carry the unit my left hand and manipulate the hose/accessory with my right hand and the exhaust/blower port will more often than not blow in the direction Im attempting to clean. BUT, this minor flaw is not a deal breaker! Just mildly annoying for someone who is a bit more OCD than not. I have, however, found a rather interesting solution to this...I take the wide angle accessory and shove it in the exhaust port. Not only does this make the machine just a bit quieter, but it also angles that air in any direction you'd like. Preferably away from what you are attempting to suck up.
-The blower side doesn't blow very hard with the hose attached to it. This is most likely due to degree of bend and ribbed inside of hose or the blade design. Not sure.
-Battery Removal: OLD STYLE SOCKET Battery a bit difficult to remove for an individual with large hands. I do not own the newer flat style battery.
Things I HAVE used it for:
-Vacuuming up drywall and garage debris
-Cleaning baseboards
-Cleaning automobile interiors, floormats, dash+center console, ect
-Vacuuming up wood dust
-Portable cleaning solution for general in-home use
Things I have NOT used it for:
-Sucking up liquids

With over 200 reviews there's not much else to offer, but I made some modifications to mine that made it a bit more useful and addressed two of it's biggest cons.
First, I got the three Shop Vac brand 14" extension wands, to extend the reach of the short hose and save me from bending over. I then mounted 3 sections of 1.5" PVC pipe cut into 9.5" sections on the bottom of the canister.This gave me a place to securely store the 3 wands and strengthened the base a bit, in case it gets dragged around in rough ground enough to eventually wear through the canister.
To mount the PVC, I used six 1/4" carriage bolts and washers on the pipe side, with bonded sealing washers (metal washers bonded to thick rubber washers) and hex bolts inside the canister.
The smooth round end of the carriage bolts inside the pipe acts to lock in the wands a few inches before the end, and they slide in and out easily but stay in securely.
Next I took the little dusting brush that Amazon says is frequently purchased with the 3 extension wands. I wanted to keep this tool with the vac along with the included nozzles. Just as I went to screw in a pipe strap to hold the brush to the vac (a setup I didn't really care for), I noticed the the outlet/blower hole. The brush fits tight in there and solves another annoying thing about this vac.
The air outlet tends to blow things around, particularly for a right hander. With the brush in there, it directs the air flow up and away from the material you're trying to vacuum, and diffused the air stream as well.
All told I think the mods cost me around twenty bucks, and added just a little weight and height to the vac, but really increased the vac's usefulness and convenience, at least for me.

I bought this as a little portable vac I could take with me to car shows for quick cleanups, but I've found this to be my go-to vac for all my jobs. It's no joke like other portable vacuums, it has just about the same suction power as my crapsman wall mount, maybe a tad more since it got the dog hair out from my daily driver's carpet. And it's way more accommodating, no need to flip hoses around, just move the vac to where you need it. The hose may look small, but does expand a lot. Plus since this thing is so portable, a longer hose is not needed.
The multiple power options are a HUGE pro in my book. Weather you are running on the 18 or 20 volt batteries, or have the option to use the cord, it seems this has the best of everything. Personally if I did have a outlet handy, I would use it for my battery charger since running it on batteries is just so much easier when it comes to maneuverability. Plus you've got a good 30 mins on the 20v 1.5ah battery.... enough time to charge your second one.
I've yet to change the filter on it, and i've read some reviews saying that the filter is expensive. But they don't say that the filter is washable, which will add some life to it. Plus I've been known to extend the life of my own filters by taking them to my compressor and blowing them out gently with a blow gun, a symptom of someone being burned by $16 paper crapsman filters.
In the end, I can't think of any cons to this vac. The power of a full size in a nice little package and the multiple power options made this the one vac that I use the most.

I've read every single review on this vac, and wanted to add mine. If you need a 5hp corded shop vac, this isn't it. It doesn't have the suction that a full size vac has, that's simply a fact. However, all tools come in different sizes that fit a particular need, and this one is no different. I bought this vac because it looked like the only one that fit my needs, and I was right. I have a 10x20 storage unit that suffered a severe mouse infestation. No power on site, mouse dropping everywhere, and I wasn't crazy about launching all that mouse dirt into the air through the exhaust port of a standard vac, assuming I'd rented a generator to power it. Broom sweeping would have accomplished pretty much the same thing. So I bought this vac and two 4 amp hour batteries, and went at it. I am completely satisfied with the vacuum, and I probably used it more today than the average user will use it in 6 months. The HEPA filter kept the dirt in the container. One note, the filter is extremely efficient, which means it keeps a larger percentage of the dirt/particulates from being blown out the exhaust. That also means you have to clean it more often. Love it, great tool. Yes it's expensive, but if it's the tool you need it's worth every dime.

light weight, compact and rugged, suction it's not a 10 but easy 7 enough to keep clean a small job site, i regular use to do maintenance in HVAC equipments, cord kind of small but always u could use batteries.

I used a Black and Decker 18V hand vacuum for about two years and was pretty happy with it until the rechargeable battery wouldn't hold a charge. When I attempted to replace the battery, I found out it was going to cost more than it would to replace the entire unit (how ridiculous is that?). I didn't love the unit, so I wasn't going to go that route again, and since I use the Dewalt 20V Max tools, I was excited about the possibility of getting a portable shop vac that would run on the same power. I ordered the DCV581H, which is even more compact than I'd imagined, and I really like the design. Elegant simplicity, very thoughtful design. We use the Dickens out of this thing! It lives in the bathroom, where the litter box is, and works beautifully. It sees a lot of action in the kitchen, after big cook sessions, the living room sofa, where our two cats and dog battle for position, for hunting 'ghost turds' that whirl around like tumbleweed in our apartment, in the car, where I can vacuum up debris from dumpster diving for lumber, and, yes, even as a shop vac! It's small and underpowered for any serious shop work, but as a benchtop cleaner, yeah, it's pretty nice. My wife is probably a little sick of hearing how much I adore this thing.

This is the best battery vacuum I have ever seen or used.
This is as powerful as my Mini-Shop Vac.
As an added benefit if your battery charge drops you can plug it in. Whether on Battery or AC Power the vac seems to have the same function.
I have been running mine on the same 4.0 Amp/Hr battery since I got it; I've used it for probably 15-20 Minutes and still have 3 Bars on the Battery.
** UPDATE ** I have used this vacuum for a few months now and it is still running great. The filter is simply rinsed under running water to clean it; I've sucked up all kinds of things including drywall dust and saw dust from my Dewalt sander and the quick emty and cleaning is great. The suction of this vacuum is astonishing especially given that it runs on 20V. I get well over 30 Minutes of solid vacuuming with a 3 Amp/Hr battery. While the power is not real increased by using a 120V outlet it does help with battery usage; though with over 2 dozen batteries that doesn't effect me too much.
This vacuum is just so convenient because of the effectiveness and battery power. It is great being able to quickly clean up a job site that doesn't have power. I'm nearly elusively running Dewalt Max battery tools now; except for the occasional job my plug in tools are relegated to the garage and because of this vacuum that includes my Shop-Vac.
Add (04/24/2016): I have added the 20 Volt Max sliding compound miter saw to my collection and while this vacuumed isn't a perfect fit a wrap or two with electrical tape makes it one. Added to the saw, to replace its horrible dust collection bag, the combination makes an almost dust free saw. Both work on batteries and allow me to bring the saw right into finished living spaces to cut. Saves time running outside and doesn't add too much bulk.
I have tried the vacuum in wet mode without the filter and this thing sucks, fast, it will fill up its just over a gallon tank within 20-30 seconds. And the float ball stops the suction before too much water gets in.
My only real CON with the vacuum is the worthless flat car attachment, it just hasn't worked for me.
As a side note in recently redoing my kitchen pairing this vacuum with my Dewalt Palm sander made sanding the drywall another dust free job.

I love this thing. The suction is a little weaker than I expected but it does an adequate job on the car carpets for a quick spot cleaning every once in a while. It is lighter in weight than I expected and that is a good thing. Nice not having to spend the extra few minutes unwinding and plugging in an extension cord then winding it all back up again afterward. I keep the thing in the garage right by the car and give it a quick vacuum whenever it needs it usually in 5 minutes or less. Nice and convenient. Arrived fast and well packaged. Recommend.

We have been using one like this for a couple of years and we needed another one. It works great to blow the saw dust and wood chips out between the studs of a new house.

5* based on limited use. Purchased for the RV because of its size, works really good plugged into wall socket. Used cordless to vacuum the cars, I don't see any noticeable loss of power. Filter replacement is kind of pricey so I'm hoping that will be a very rare event. Only comes with 2 accessory tools, a 1-1/4" accessory kit is a perfect match for it.
