Dewalt 20v max wet-dry vacuum dcv581H review

Sometimes you need to use a vacuum but there is no power close by or getting out 200ft of extension cord is just not worth the hassle. Dewalt has solved this issue the DCV581H Wet/Dry vacuum. I personally have used this vacuum now for over 2 years on the job, here are my thoughts.

(above) Suction test of the vacuum picking up some large debris. I would say the suction is good, but not great. It’s perfect for small and quick clean up jobs. Most 120v plug in shop vacs will have more suction power.

While the unit is easy to open, it’s kind of a pain to empty, the dirt bucket has a large lip around all sides and it makes it tricky to get 100% of the debris out.

While the unit has a 2 gallon capacity is still remains quite compact in size, I like how everything has a place on the unit and it can stay neat while not in use.

This unit can be powered by a 20v battery, the old 18v stick batteries or a 120v plug which is attached to the unit. While I never really need to plug it in, you get more than enough run time with a 4ah or 5ah battery for a workday.

Great battery life, good but could better suction and easy to clean filter make this one of my favorite clean up tools out there. Better if you can find a deal on one, it’s highly recommended from me.
