Zoom on the DeWalt DXPW3425
The DeWalt DXPW3425, a heavy duty, commercial pressure washer, gives its user an all-around versatile cleaning experience, topped off by the following features:
- spot cleaning of hard, unpainted surfaces and high-reach cleaning
- thorough cleaning of hard, paint-free surfaces
- cleaning of painted or delicate surfaces
- application of detergent and cleaning solutions
Powered by a 196 cc (5.8 hp) engine, its triplex pump can deliver a pressure of 3400 PSI (around 57 times more than a standard garden hose) and a flow of up to 2.5 GPM (values claimed by the manufacturer). Combined, these values mean that the DeWalt DXPW3425 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.
Gasoline storage is facilitated by a fuel tank with a maximum capacity of 0.82 gallon.
Design & Handling
The wheelbarrow design of the DeWalt DXPW3425 grants mobility and stability to the unit. The strong welded steel frame assures assembly longevity. The handle adds to the DXPW3425 convenience of transport.
The unit's weight of 83 lbs renders its carrying and transportation challenging, as it is far from lightweight. Its 196 cc Honda GX200 engine, the triplex pump and welded steel frame add up to a large chunk of the device's weight. However, the unit is mobile thanks to its two 10" pneumatic wheels, which add to its movability and allow it to be manipulated smoothly on the job.
The DeWalt DXPW3425 comes with a spray gun, a wand, a pressure hose, 5 nozzles and a detergent injection feature, which are detailed below.
- Soap injection: While the device doesn't feature a soap tank, detergent supply is ensured by a siphon hose. The detergent is automatically added to the water when a soap nozzle is connected.
- 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: Both the classic ergonomic spray gun and its wand may be conveniently stored in a side hook. A rotating auxiliary side handle further improves both left-handed and right-handed users' comfort.
- 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 thermal relief valve (which helps to prevent internal pump damage), a trigger lock mechanism (which prevents accidental operation) and a low oil protection.
- Accessories: Included with the DeWalt DXPW3425 are also the owner's manual (opens in a new tab) and some basic documentation to get you promptly started, along with several accessories, such as wand, nozzle cleaner, soap hose, spray gun, oil and pressure hose.

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, reaching a PSI of up to 3400, is one of the more powerful gas-powered units in $400-500 price range. If your priority is the highest possible power of the water stream, in this price range, we suggest checking out the Briggs & Stratton 20647, which reaches up to 3600 PSI.
- As this washer can produce a flow of water of 2.5 GPM (gallons per minute), it is average in terms of water volume for the above-mentioned 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 Lifan LFQ3370, which can reach up to 3 GPM.
- The DXPW3425, which reaches up to 8500 Cleaning Units (PSI x GPM) is one of the more efficient, in comparison to its similarly priced counterparts. If the highest overall cleaning power is your top priority, the Lifan LFQ3370, which can reach up to 9900 Cleaning Units, is one of the most efficient of the devices in the current price range.
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.
