Are Dewalt pressure washers made by Simpson?

Yes, Dewalt pressure washers are made by Simpson. In fact, pressure washers from both brands are manufactured by the same unit. Simpson has a large state-of-the-art manufacturing facility in Decatur, Arkansas where they also design and produce Dewalt pressure washers along with Simpson. This is the main reason for the similarities in design between these two pressure washer brands.

DeWalt vs. Simpson Pressure Washer: What is the difference?

Engine Quality and Efficiency

Both brands use Honda Engines in some of the pressure washers. So I don’t want to say anything in that case. Because you know better how famous are Honda engines for their high quality and efficiency? You can definitely expect a high level of performance and reliability from either brand

Simson also uses Kohler engines in their machines. Kohler is a reliable brand but not more efficient than Honda. On the other hand, DeWalt uses its own engines in some of its pressure washers.

If I have to compare the Kohler engine and the DeWalt engine, I will definitely go with the Kohler engine. That ultimately put my vote in the Simpson’s box.

Kohler has a vast background in powerful and reliable engines. They are also less noisy than DeWalt engines.

So in terms of engine quality, Simpson is the winner. You can choose Simpson without worrying about engine efficiency and maintenance.

Pump Quality

This is my favorite part of the comparison.

The pressure washer is known for just one thing, its pressure. If you are unconcerned with a budget and are solely focused on selecting the best pressure washer for your cleaning tasks, then pressure is the only factor that truly matters in making your decision.

Only a good pump can produce good pressure for a long period of time.

Without any delay, I admit that DeWalt takes the clear lead here.

DeWalt uses CAT Triplex Plunger Pump in their most pressure washers. They are the best in the industry without any doubt.

They are maintenance-free and perform well during rigorous cleaning tasks. You can bet on their delivery of pressure during hours-long operations with their thermal relief valves.

Simpson uses an AAA Triplex Pump. They are also reliable but not up to the mark of CAT Triplex pumps. So DeWalt wins this comparison.


Simpson pressure washers are definitely a better choice for those looking for the best price.

This is because Simpson pressure washers are more affordable than DeWalt pressure washers for models with comparable features and specifications.

For example, when I compared pressure washers from both brands having Honda engines and other same specs, the Simpson pressure washer was more affordable than Dewalt.

In addition to Honda engines, some Simpson models come with Kohler or Simpson’s own brand of engines, which can also provide similar performance at a lower cost.

So if I have to decide between DeWalt Vs Simpson Pressure Washer, I will choose Simpson for my residential cleaning tasks.


Comparing DeWalt and Simpson pressure washers was a difficult task for me because they each have their own strengths.

DeWalt is a powerful brand that offers high-quality equipment in their pressure washers, while Simpson provides a more affordable option with a range of engine choices and durable construction.

If you have read my complete article above about Simpson Vs DeWalt Pressure Washers, I know you can choose the right machine for you now.

However, if you want my further assessment of these brands, I will conclude it here.

Both DeWalt and Simpson offer high-quality pressure washers with efficient engines that can handle a variety of cleaning tasks.

DeWalt’s machines are known for their powerful CAT pumps, which can provide greater water flow and pressure for heavy-duty cleaning jobs.

Meanwhile, Simpson offers a more affordable option with a range of engine choices and durable construction that can provide reliable and consistent performance over time.

So ultimately, the choice between DeWalt and Simpson comes down to your individual needs and budget. If you’re looking for a machine that can handle the toughest cleaning jobs and doesn’t mind paying a premium, then DeWalt may be the better option.

However, if you’re looking for a more affordable machine that can still provide reliable and consistent performance, then Simpson may be the better choice.

Regardless of which brand you choose, both DeWalt and Simpson offer quality products that can make your cleaning tasks easier and more efficient.
