Our Testing Experience
First Impressions
When I first took the 20V Cordless Vacuum Cleaner out of the box, I was impressed by how lightweight and easy to handle it felt. I charged my DeWALT battery and got started right away. Setting it up was simple, and I loved that it didn’t have any cords to worry about. My first test was cleaning the car interior, and I was surprised by how powerful it was for such a small vacuum.
Daily Use
Over the next few days, I used the vacuum around the house and in my workshop. It was great for quickly picking up dust, small debris, and even some wet spills. The 2.6-gallon capacity meant I didn’t have to empty it too often, which saved me time. Using it without a cord made moving from room to room so easy. I even used it to clean up sawdust after a small woodworking project, and it handled the mess well.
Key Features in Action
The cordless design was definitely the best part for me. Not having to plug and unplug while moving around felt freeing. The wet/dry capability was also very useful—I accidentally spilled some water while cleaning, and the vacuum picked it up without any issues. The compatibility with my existing DeWALT batteries was a big plus since I didn’t need to buy a separate battery. The suction power stayed strong throughout each use, which made cleaning quick and effective.
Long-Term Performance
After a few weeks of regular use, the vacuum still worked just as well as on day one. The battery held a good charge, and the filter was easy to clean. I didn’t notice any drop in suction or performance. It became my go-to tool for quick cleanups around the house and workshop. Overall, it’s a reliable vacuum that makes cleaning less of a chore, especially with its cordless convenience and solid capacity.
