DeWalt 20 Volt Cordless Vacuum Cleaner: An Overview

dewalt 20 volt vacuum review

The DeWalt 20 Volt Vacuum Cleaner is a portable, handheld wet/dry vacuum that can accommodate up to ½ gallon of debris.

Powered by a 20 volt MAX lithium ion battery, it holds its power for a long time so you can get the job done. When it’s time to recharge, it powers back up in no time.

Outfitted with a HEPA wet/dry filter, the DeWalt 20 Volt Vacuum filters and sucks up to 99.97% of dust, dirt, debris, and particles that are as small as 0.3 microns (as small as bacteria, that’s super tiny). You’ll be able to use this tool to effectively clean up the finest debris, such as drywall and masonry dust. When you’re finished cleaning, simply remove the HEPA filter, run it under tap water until it runs clean, allow it to dry, and replace it.

Dual Cleaning Modes

With dual cleaning modes – a utility nozzle and an extendable heavy-duty rubber hose – the DeWalt 20 Volt Vacuum is highly versatile and can be used to clean just about anywhere.

With a ½ gallon tank, it provides plenty of storage space to accommodate the debris from small- to mid-sized cleaning projects, and a heavy-duty latch keeps the tank secured in place while cleaning. When you need to empty it out, just pop open the latch, empty out the dirty, replace the tank, and you’ll be ready for your next cleaning project. The flexible 2.5 foot hose attachment can be extended to 5 feet and the “no-crush” design ensures a stable opening. A membrane filter makes this tool suitable for both wet and dry pickup, and the built-in gulper-style nozzle makes picking up those larger messes a cinch.

The DeWalt Vacuum 20 Volt is also compatible with standard vacuum attachments; however, do note that you’ll need to use a DWV9000 adapter in order to use them, and it’s sold separately.


Since the DeWalt Cordless Vacuum 20 Volt is portable, you’ll have access to reliable cleaning power whenever you need it. The lightweight, compact, yet rugged design makes it perfect for taking back and forth from worksite to home and back again.

Plus, because it doesn’t take up a lot of space, it’s easy to store when you’re finished using it. The built-in comfort grip handle also adds to the ease of portability

Battery Life, Power, & DeWalt Customer Loyalty Benefits

Powered by a 20 volt 4.0Ah battery with no memory and virtually no self-discharge, you’ll have less downtime and more productivity.

Although the battery life is not the most impressive at about 20 minutes or so, it’s still plenty of time to get a considerable amount of cleaning done.

For even more power and runtime, the DeWalt Cordless Vacuum is also compatibility with the DeWalt 60 Volt FlexVolt batteries which you can buy here, so for those times when you need more power for a longer period of time, you can simply switch out the battery (additionally batteries are sold separately).

Do note that you can either purchase the DeWalt Vacuum 20 Volt as a stand-alone vacuum and use almost any other DeWalt batteries that you may already own or purchase the specific type of battery that you’d like to use, or you can purchase it as a bundle pack, which comes complete with a 20 volt lithium ion rechargeable battery, as well as a charger.

Who is the DeWalt 20 Volt Vacuum Cleaner Best For?

The DeWalt 20 Volt Cordless Vacuum, as mentioned, is ideal for small – medium projects.

With a ½ gallon tank, it can’t accommodate too much debris; however, it can pick up just enough for smaller and medium projects, such as cleaning up after you cut drywall, wood, or sand spackle. Since it’s a wet/dry vacuum, it can also be used to clean up any small or medium liquid spills that may happen at the job site, in your garage, or even just around the house.

In our opinion, this portable wet/dry vacuum is suitable for both professionals and DIY enthusiasts alike. It’s cordless and has a lightweight and compact design, which makes it really easy to transport and use wherever you need it. With advanced HEPA filtration, you’ll have confidence knowing that even the tiniest particles will be caught and trapped inside the filter, so it won’t impact the quality of your indoor air; in fact, it will improve it.

Cleaning up the DeWalt 20 Volt Cordless Vacuum after, well, cleaning up, is an absolute breeze. Just pop open the tank, empty it out, remove the HEPA filter, run it under water until it’s clean, allow it to dry, replace, and you’ll be ready to store it until you need it again.

With great suction, impressive power, and decent runtime (roughly 20 minutes, unless you upgrade to a more powerful 60 Volt FlexVolt battery, which will enhance the power and runtime), you should have no trouble cleaning up any small dry/wet messes.
