Zoom on the DeWalt DXPW4035

The DeWalt DXPW4035, 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, paint-free surfaces and out-of-reach areas
  • intense cleaning of tough, paintless surfaces
  • cleaning of painted and fragile surfaces
  • applying detergent and cleaning solutions

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

The DeWalt DXPW4035 in use

The DeWalt DXPW4035

The DeWalt DXPW4035's triplex pump, powered by a powerful 269 cc (8.4 hp) engine, can provide a pressure of up to 4000 PSI (approximately 67 times more than a standard garden hose) and a flow of up to 3.5 GPM (CETA-certified values). The DeWalt DXPW4035 thus has a cleaning power of 14000 Cleaning Units.

The Honda GX270 engine of this gas-powered pressure washer gets started by a classic pull-start mechanism.

The fuel is stored in a tank, which can hold up to 1.4 gallon of gasoline.

Design & Handling

The wheelbarrow design of the DeWalt DXPW4035 grants mobility and stability to the unit. The robust and sturdy welded steel frame offers longevity to the assembly. The handle adds to the DXPW4035 convenience of transport.

At 126 lbs, we can't really say that the unit is a lightweight, and manually lifting or transporting it could be a challenge. Its 269 cc Honda GX270 engine, the triplex pump and welded steel frame add up to a large chunk of the device's weight. However, the device’s two 13" pneumatic wheels play a key role in its maneuvrability, as they allow it to be manipulated smoothly.

Main Features

The DeWalt DXPW4035'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. Whenever a soap nozzle is connected, the detergent is automatically added to the water.
  • Pressure hose: The included 50 ft ⌀3/8" high-pressure hose can be neatly stored on the unit when idle thanks to 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 table below shows you the 5 included nozzles, as well as the surfaces they're the most appropriate for.

    Used the pressure washer twice. Worked fine. The third time the vent on the pump started blowing water out. Called warranty department and took the machine to their repair center. The pump seals went bad after 2 tanks of fuel(less than 8hrs. of use) They have had the machine for almost 6 weeks and still hasn’t been repaired. They said the seal kit is not in their inventory yet. Why not replace the entire pump? Or the entire machine? Or refund my money?? Meanwhile I have had to rent a machine twice while my new pressure washer sits. Shame on you DEWALT. You have lost a costumer for life. Buy this pressure washer and you will be disappointed.

    + PROS: worked great the first 2 times
    - CONS: when it breaks your screwed.

    I purchase this model in April 2021. Worked great until I need to add more fuel. Would not start again. Tried for two days… (did all the basic stuff, release gun pressure, etc..). I called Dewalt support. They had no clue, told me to take in for service. Really? After 45 minutes of use?
    I then bought the model below this one last week. (May 2021) Within 10 minutes of use, two of the 4 pump bolts came loose, sprayed oil all over my stamped patio.

    + PROS: Ran great for a short time
    - CONS: Broke in less than an hour... 2 of them
