We want to make sure we are all on the same page, this is not a pressure washer. This is a power washer with a lot less power! A pressure washer creates pressure that can vary from 1500-4400 psi, this power washer puts out a maximum pressure of 550PSI. Think of this tool as a pressure booster for your hose. The best part is how much quieter these are than a gas powered pressure washer, they are really portable and nearly zero maintenance.

New to the Industry

Portable power washers are a relatively new addition to the industry.  Other brands have already released cordless power washers, but when it comes to Max PSI output, DEWALT has a significant advantage. Most competitors have a maximum PSI of 320, whereas the DEWALT has a PSI output that is more than 70% higher than the other brands.

Using the DCPW550B

The DCPW550B can be used for many applications. In New England this time of year the pollen is horrific. If you do not stay on top of cleaning your automobiles or patio/deck furniture they will soon be the color yellow!

Car Washing

We took the power washer to the cars first. After filling up the soap container we attached it to the power washer and applied the soap. The PSI was low and it didn’t seem like the soap was being shot out at a high enough pressure to be effective.

Once the truck was soaped up we connected the long wand with the 40° nozzle and rinsed it off. Switching over to the turbo nozzle and it was powerful enough to get all the build-up crud inside the wheel wells and running board.  Started the washing process off using a 20v 5.0 Ah battery and it made it 3/4 of the way. We ended up putting a 60v Flexvolt battery in the washer and finished the rest of one vehicle and the entire second truck.

Power Washing

With Spring in the air, it is time to uncover the deck furniture from the winter hibernation.  With this, we felt it was a great time to power wash the deck as well and get it ready for the summer BBQs that await! Started cleaning the patio furniture that was just covered in pollen, quickly went from yellow back to black!

We moved to the deck after cleaning up the furniture. On the deck board, the DEWALT DCPW550B performed admirably. I’m embarrassed to admit but this was the first time I’d washed my deck since it was built in 2017. For the deck boards, we used the 25° nozzle. The 550PSI pressure was more than enough power to remove the pollen, bird crap, dirt, and leaves.

   The quick connect for the garden hose snapped off 5 seconds into operating. The rest is going back in the box and returning. My expectations were maybe a bit high.
