Rated 5 out of 5 by from Fantastic I have had this vac for about four years now. Absolutely love the tool, the ac power is a big help as well. Cannot think of a thing I have to say in the negative. 7-

Rated 1 out of 5 by from Not rated for home use Worked fine for a few months cleaning cars and small messes around the house. Now it will not turn on. Product only worked for less than 6 months.

Rated 3 out of 5 by from Wanted to love it I’ve had this for about 2 years now. I wanted to love this thing so bad. In theory it’s perfect, it hits all the bullet points. Corded or cordless with my current batteries, perfect size and capacity, nice attachments, etc. It just seriously lacks power. Very disappointed the first time I used it and Ive given it plenty of chances since then thinking I’d learn to like it, still disappointed. It’s fine for cleaning up small messes of shavings or sawdust but there are far better options like the small hand held Dewalt 20v vacuum for jobs of that size. I thought it would be perfect for cleaning out vehicles, it just doesn’t have the power to pick things from carpet it seems.

Rated 1 out of 5 by from Repeated Failure Failure I've had three of these vacuums: All purchased in 2019, and all of them have failed. One of the vacuums started having problems immediately. The vacuum would cur in an out during use, and would eventually stop working completely. I returned this one immediately, and got a replacement. The replacement vacuum I received would go on to do this exact thing again twice. Both times I was able to send this back to DeWalt for Warranty work. The third vacuum was trouble free for 2 years, until failing victim to the same exact problem. All three vacuums were used in a home setting. So three vacuums, same problem. Eventually something in the vacuum wears out, and fails.

Rated 4 out of 5 by from totaly cool I love this. Been looking at one for a long time and then my wife said "buy it". Love the the idea that I can use AC when available and Battery when not. I had wished that they would make a version that also charged the battery. most of the charger components would fit easily and a 3 position switch near the battery that could select Run/Off/Charge.

Rated 1 out of 5 by from Lasted a year I used this Shop Vac a total of three times. When I finally went to use it again a year later, it wouldn't provide any suction unless I took out the filter. This is the first time Dewalt has let me down. Now I am getting ready to throw out this unit. VERY disappointed in Dewalt.

Rated 4 out of 5 by from Powerful No, Convenient Yes! Let's be clear this vacuum was designed for convenience not performance. It is a small well designed vacuum that is perfect for bringing to the "one day" job site. If I have to cut a hole in the wall for a electrical box or drill a hole through a cabinet it is going to make a mess in my clients house. This vacuum is perfect for picking up after those small messes. Being that it is cordless or corded it makes it that much easier. It's compact design and well thought out ergonomics that incorporates the hose/tools are integrated into the vacuum body without protruding outwardly. It easily fits in the truck in the morning without dragging hoses or cords...and the accessories stay put unlike my shop vac. It helps me be a better carpenter for my customers. That said it is not about performance. It has about half the suction power of my standard shop vac (see photo). But if you are picking up dust or wood shavings this guy is up to the job. Quick and easy.

Rated 5 out of 5 by from Convenience Most Important for Vacuum Great to be able to use 581H vacuum on either 110VAC or 20V battery. Need to keep filter clean to maintain maximum suction. I used it first on cool ashes in fireplace, after burning a non-wood fireplace log. Ash was consistency of drywall dust, and HEPA filter did its job of preventing blow-out through the exhaust opening. But the filter clogged quickly, and then the vacuum lost its suction. This is the exact same situation that occurs when I use my regular, full-size shop vac. For regular vacuum clean-up jobs -- not the superfine "dust" jobs -- this vacuum does the job well. Noticed no difference in power between either AC or battery operation. The portability, especially when using a battery, makes this a great tool to have .... just keep the filter clean!
