This high-performance 4400 PSI 4.0 GPM Cold Water Gas Pressure Washer features a triplex pump and a 389cc Honda® GX390 engine to drive its powerful operation.
Zoom on the DeWalt DXPW4440
In a nutshell, the DeWalt DXPW4440 is a commercial pressure washer, which not only offers an all-around versatile cleaning experience, but that also allows:
- pinpoint spot cleaning of hard, unpainted surfaces, accessing high areas, and successfully removing stubborn stains
- overall cleaning of hard surfaces, washing vehicles, and prepping surfaces for painting
- soft cleaning of delicate surfaces, and gentle cleaning for larger areas with low pressure
- applying detergent and cleaning solutions, and rinsing surfaces
The following sections will present you in detail its power characteristics and design, its main features and all the additional features it has to offer.
Power
Using an impressive 389cc (11.7 hp) engine, its triplex pump delivers a pressure of up to 4400 PSI (roughly 73 times more than a standard garden hose) and a flow of up to 4 GPM (CETA-certified values). When these values are taken together, they yield a cleaning power of 17600 Cleaning Units.
Starting the Honda GX390 engine of this gas pressure washer involves using a conventional pull-start method.
The pressure washer's tank has a maximum capacity of 1.6 gallon for storing gasoline.
Design & Handling
The DeWalt DXPW4440's wheelbarrow-style design enhances both mobility and stability, enabling seamless navigation and consistent performance, even on rugged terrain. The durable welded steel frame of the assembly ensures its longevity, providing stability and shielding internal components from damage, even in tough conditions. The handle adds to the DXPW4440 convenience of transport.
At 139 lbs, this unit's substantial weight makes it quite a challenge for users to lift and maneuver, particularly on uneven surfaces where its heft can become even more apparent. Its 389cc Honda GX390 engine, the triplex pump and welded steel frame are mainly responsible for its heavy weight. However, the incorporation of two 13" pneumatic wheels makes navigating the DXPW4440 less cumbersome, even on uneven terrain.
Main Features
The DeWalt DXPW4440 comes with a spray gun, a wand, a pressure hose, 5 nozzles and a detergent injection feature, which are detailed below.
- Soap injection: While not equipped with a soap tank, the device maintains detergent supply through a siphon hose. Connection of a soap nozzle triggers the pressure washer to automatically incorporate the detergent into the water stream.
- Pressure hose: The unit comes equipped with an included 50 ft ⌀3/8" high-pressure hose, which can be neatly stored on the unit when idle, thanks to a set of convenient hooks, ensuring easy access and organization.
- Spray gun and wand: A side hook enables you to easily store the included classic ergonomic spray gun and its wand. The gun features a rotating auxiliary side handle to further improve the comfort of both left and right-handed users.
- Nozzles: In the table below, you can see the 5 included nozzles alongside their respective recommended surface uses.

User Reviews
I have 3 DeWalt 4400,4200, and 4000 PSI pressure washers. I also have a Husqvarna 3200.
The DeWalt units have been great for the past three years.
Bought it and in third use the pump leaked all of its oil thru the see-thru gauge on the front. Disappointed.
