Best Uses
Solid performance meets expectations
I purchased this unit mostly for small clean-ups after minor repairs, like drywall dust or sawdust. For that use it's very good. Easy to move around, and powerful enough to suck up little stuff. Does not do a great job of collecting nuts and bolts, but shavings, dust, bits of paper, and dust bunnies are no problem. Maybe best to think of it as a tool for neatening up, and will be great for touching up in the car--not powerful enough for a full cleaning, but will help keep the squalor at a manageable level.
I also used it at a trade show to vacuum carpet each morning before opening. Battery power saved me the price of the unit because I did not have to buy power from the facility. I cleaned my booth twice (10x20 feet) on a single charge of my 3 Ah battery. Not completely spotless like you'd get from a carpet vac, but it picked up all the stuff you can see when you are standing on the carpet.
The hose is a bit short, but then again corrugated hose is a suction-killer, so maybe short is OK. Carry the vac in 1 hand and hold the nozzle in the other and you'll have no problems.
Bottom line: a great convenience item for small jobs where hauling a bigger vac (even my Fein Turbo iii, which is not very big) is too much of a pain. Not a replacement for a proper vac for big jobs, but awesome for the little stuff. Would be nice for a contractor as you could easily clean as you go, which clients will appreciate.

Love it!
Bought this to for occasional use but it has repidly become my go to vac over my big shop vac for most many jobs. Very convenient and lightweight with very good suction. Can't pick up larger chunks of wood, etc. but no regrets. Love it!

Convenient and Portable
As a handyman I find this little unit extremely useful. It doesn't replace a full size shop-vac for the deep clean up, but this is fantastic to bring along to clean up those small piles of sawdust or light debris.

The unit doesn't have a ton of suction, but it does pretty well considering its size and running on a battery. I generally get about 10 minutes on a 1.5 Ah battery pack.

Overall, I find this unit really useful. It doesn't replace a full size vac, but for those small jobs where you may not have electricity available, it is fantastic.

Great Product
I like the cordless feature so I am not dragging around power cords. Has the necessary power. I use in garage, cars and around the house for most any kind of vacuuming except house carpeting. Works great on carpeted steps because it is light and easy to carry up and down.Works on Dewalt batteries that I already have for other tools.

Great portable vacuume
I use this vacuume to clean up after lock installs and other small messes while working. I love the fact that I can plug it In to use it or use a dewalt battery to power it.

Awesome vac!
Used daily on construction projects, excellent for quick clean ups. Love that it can be used with batteries or cord, even though I have only plugged it in once to save a trip to the trailer to get a fresh battery. Acceptable run time from both my 18V and 20V batteries, about 30 minutes. Great buy!

20v cordless/corded Dewalt shopvac
I purchased the vacuum and I absolutely love it, it does everything that I want it to and more. I have my own carpentry business and I have used this on all of the jobs since I purchased it. Great suction and battery life. I bought this on over the one with just the battery so I would have the option of plugging it in but I rarely do. I would definitely recommend this product to everyone from do it yourselfers to guys in the carpentry field like myself. This is an all around great product. Thanks dewalt.

A shopper on Jul 10, 2017
does this work or attach to miter or table saw?
Joriz on May 2, 2016
BEST ANSWER: No it doesn't seem to.
I tried it on my Dewalt cordless miter saw and it fits loose in the
discharge tube.
Can't say for the table saw since I don't have one but I'm sure it doesn't
fit one either.

New Vs. Reconditioned

What's the difference between New and Factory-Reconditioned?

Factory-Reconditioned products have been returned to the manufacturer and are restored to like-new operating condition; they go through a rigorous testing and inspection process. Plus, they offer a significant savings vs. new.
  • Reconditioned products may have minor cosmetic blemishes or scratches that do not affect item performance.
  • Reconditioned products may not come with all of the consumables the new version comes with (bits, sanding pads/papers, cases, etc.).
  • Both come with a manufacturer warranty and are covered by our Money Back Guarantee; New is 30 days, Reconditioned is 120 days.
