The DeWalt DXPW3425 is a gas-powered pressure washer offering a maximum water pressure of 3400 PSI and flow of 2.5 GPM. (Read full specs)
Zoom on the DeWalt DXPW3425
In a nutshell, the DeWalt DXPW3425 is a heavy duty, commercial pressure washer, which not only offers an all-around versatile cleaning experience, but that also allows:
- spot cleaning of hard, paint-free surfaces and out-of-reach areas
- intense cleaning of hard, unpainted surfaces
- cleaning of painted and frail surfaces
- use of detergent and cleaning solutions
The DeWalt DXPW3425's triplex pump, powered by a 196 cc (5.8 hp) engine, can provide a pressure of up to 3400 PSI (approximately 57 times more than a standard garden hose) and a flow of up to 2.5 GPM (values claimed by the manufacturer). The DeWalt DXPW3425 thus has a cleaning power of 8500 Cleaning Units.
This gas-powered pressure washer’s Honda GX200 engine is started by a traditional pull-start mechanism.
The fuel is stored in a tank, which can hold up to 0.82 gallon of gasoline.
Design & Handling
The wheelbarrow design of the DeWalt DXPW3425 grants mobility and stability to the unit. The robust and sturdy welded steel frame offers longevity to the assembly. The handle adds to the DXPW3425 convenience of transport.
At 83 lbs, we can't really say that the unit is a lightweight, and manually lifting or transporting it could be a challenge. The major reasons for its heavy weight are its 196 cc Honda GX200 engine, the triplex pump and welded steel frame. However, the unit is manipulated smoothly thanks to its two 10" pneumatic wheels, which play a key role in its maneuvrability.
The DeWalt DXPW3425's package includes a spray gun, a wand, a pressure hose, 5 nozzles and a detergent injection feature, with a more detailed description below.
- Soap injection: Detergent is fed in through a siphon hose, since the device lacks a soap tank. The detergent will be added automatically to the water when a soap nozzle is attached.
- Pressure hose: The 25 ft ⌀1/4" high-pressure hose, which is included with the device, can be stored neatly on the unit itself when idle, using a set of convenient hooks.
- Spray gun and wand: The included classic ergonomic spray gun and its wand can be easily stored in a side hook. The gun features a rotating auxiliary side handle to further improve the comfort of both left and right-handed users.
- Nozzles: The 5 nozzles included with the device, and the respective surfaces which they’re the most suitable for, are shown in the following table.

- Safety: Safety of operation is enhanced by a trigger lock mechanism (which prevents accidental operation), a thermal relief valve (which helps to prevent internal pump damage) and a low oil protection.

The DeWalt DXPW3425's performance versus other pressure washers
The following charts are provided to give you an idea of how the key specs of the DeWalt DXPW3425 compare to similarly priced pressure washers.
- The DeWalt DXPW3425, which can reach a PSI of 3400, achieves an average pressure output, compared to other gas-powered units that cost between $475 and $625. If the highest possible power of the water stream is your priority, one of the champions in this price range is the A-iPower APW4200 with 4200 PSI.
- The achievable water flow of this washer, which reaches 2.5 GPM (gallons per minute) can be described as low, compared to other devices in its price range. If rinsing away debris most efficiently is your priority, one of the devices with the highest GPM in this price range is the A-iPower APW4200, which can reach up to 4 GPM.
- With the DXPW3425's 8500 Cleaning Units (PSI x GPM), its cleaning efficiency range may be considered average, compared to gas-powered units of similar price. If you consider the highest overall cleaning power as a really important factor, the A-iPower APW4200 and its 16800 Cleaning Units has one of the highest cleaning efficiency of all the similarly priced units.
As you can see from this interactive chart, when compared to other gas-powered washers between 8000 and 8500 Cleaning Units, the DeWalt DXPW3425 is on the average side of the price range.
Therefore, this pressure washer nicely fits in the expected budget for this kind of cleaning power.
