Description

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, unpainted surfaces and high-reach cleaning
  • intense cleaning of tough, paintless surfaces
  • cleaning of painted or delicate surfaces
  • use of detergent and cleaning solutions

Its power characteristics and design, its main features and all its additional features are presented ahead.

Power

The DeWalt DXPW3425's triplex pump, powered by a 196cc (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 (CETA-certified values). 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 strong welded steel frame assures assembly longevity. The handle adds to the DXPW3425 convenience of transport.

This model weighs 83 lbs. For this reason, it cannot be called lightweight and thus, carrying and transporting it might be somewhat challenging. The main contributors to its weight are its 196cc Honda GX200 engine, the triplex pump and welded steel frame. 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.

Main Features

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: Even though the device doesn't have a soap tank, detergent is supplied by a siphon hose. When a soap nozzle is connected, the detergent will be added automatically to the water.
  • 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: A side hook allows for an easy storage of the included classic ergonomic spray gun and its wand. A rotating auxiliary side handle further improves both left-handed and right-handed users' comfort.
  • Nozzles: The following table illustrates the 5 included nozzles, along with the surfaces which they are the most suitable for.

Other Features

  • Onboard storage: Stay prepared for any job with DeWalt DXPW3425's handy storage area, which allows you to neatly store any nozzles and accessories which you may need for the job.
  • 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.
  • Accessories: Besides the usual owner's manual (opens in a new tab) and documentation to get you promptly started, the DeWalt DXPW3425 comes with soap hose, pressure hose, nozzle cleaner, spray gun, wand and oil.
  • Emissions: The DeWalt DXPW3425 is EPA-approved and CARB-compliant. This means that this pressure washer can be bought and sold in each of the 50 states, including California.

    The plastic housing which I believe is the water sensor that is connected to the garden hose broke the second time I used it. I would not recommend this to anybody.

    + PROS: It definitely will put some pressure on the material that you are spraying.
    - CONS: It will not last more than two, uses to three uses with the pressure sensor plastic piece.

    The Dewalt DXPW3425E has a water sensor that has a plastic housing that cracks….stay away from this unit. The closest warranty center is over 100 miles away and a three week period to get repaired. Very disappointed with Dewalt for their lack of concern for a well known defect in design . These units with this part are all over the internet for sale because of this. Never buying Dewalt products again!

    + PROS: Honda motor and pump perform well
    - CONS: Dewalt's lack of customer service and support for their poor decision on using a plastic housing for a water pressure sensor

    I bought a “returned/rebuilt” pressure washer a little over a year ago for personal use. I also bought an 18 inch surface cleaner. Compared to smaller units that I have borrowed from my neighbors, this one is a dream for cleaning driveways and sidewalks. So far I have no complaints with this DeWalt pressure washer and attachment.

    I use it on mine, and two of my children’s properties.

    + PROS: Much faster than using smaller units.
    - CONS: Trying to find O-rings that fit at home improvement stores is difficult. The brands they carry don't seem to be exactly what is needed.
