DEWALT DCV581H 18/20-Volt MAX Cordless/Corded Wet-Dry Vacuum Review

The DeWalt DCV581H 18/20-Volt MAX Cordless/Corded Wet-Dry Vacuum is a fantastic light duty tool for any homeowner, car detailer, car enthusiast, and anyone who needs to clean up small messes on a regular basis. DeWalt created this vac with everything you would expect from a wet/dry unit, but made it small in size so it's portable and easy to store when not in use. When you purchase this vacuum, you'll soon appreciate its ability to be used with or without a cord as well as its washable HEPA filter.

In this review, I'll go over the best features of the DeWalt DCV581VH and explain why you would need one of these in your home.​

I'll also discuss the pros and cons associated with the product, and talk specifically about what other customers had to say about the vacuum after using it themselves.

Corded or Cordless Use

When you purchase a wet/dry vacuum, you'll usually have to choose between corded or cordless models. However, that's not the case with this model. This unit can be powered by an AC outlet and cord, or used without a cord with an 18-volt or 20-volt battery. The ability to choose whether you want to use this vacuum with or without the cord extends the usability of it and makes it easy to transport as well. Adding to the ease of portability is a durable handle.

HEPA-Rated Filter

To make sure you're getting as many contaminants as possible out of the air, DeWalt created the DCV581H with a HEPA-rated filter. This filter will trap up to 99.97% of contaminants. Unlike other wet/dry vacs with the same feature, the filter on this model is easily accessible and the filter itself is easy to change. Many previous customers have mentioned that the filter is expensive to replace, but it's important to note the filter can be easily cleaned and reused. In fact, it just takes simple tap water to clean the filter.

5 Feet of Crush-Resistant Hose

DeWalt added 5 feet of crush-resistant hose to this corded/cordless wet/dry vacuum. The hose is made of heavy-duty materials and has a 1/4" diameter. With this sturdy hose, you can expect durability, flexibility, and ease of use every time you get this vacuum out.

On-Board Storage for Accessories

The 18/20-volt wet-dry vac comes with a variety of accessories including a crevice tool and nozzle tool attachment. DeWalt added on-board storage to the vacuum to make it easy to keep accessories neatly organized and ready to use when needed. Adding to this small wet/dry vac's popularity is the fact that it isn't as big as a standard unit. With its small size and storage, you can easily store it in your garage, shed, or basement without taking up valuable space.

This DeWalt wet/dry vacuum has so far garnered many positive reviews across various independent review sites. The people who loved the vacuum praise its small size and ability to clean up most messes. The customers who purchased this DeWalt unit and weren't happy cited the vac's lack of power. It's important to note that this wet-dry vacuum isn't supposed to be extremely powerful. It's a light duty tool for car detailing and easy clean-up. If you need a more powerful vac, there are better options on the market. On the other hand, if you're just looking for something that will clean the crumbs out of your backseat or the sawdust off the workshop floor, the DCV581H will be perfect for you.
