Zoom on the DeWalt DXPW4035

In summary, the DeWalt DXPW4035 is a heavy duty, commercial pressure washer, that offers an all-around versatile cleaning experience, and also:

  • spot cleaning of hard, paintless surfaces and reaching far-away areas
  • thorough cleaning of hard, paint-free surfaces
  • cleaning of painted and frail surfaces
  • use of 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.


The DeWalt DXPW4035 in use

The DeWalt DXPW4035

With an impressive 269cc (8.4 hp) engine, its triplex pump delivers a pressure of 4000 PSI (roughly 67 times more than a standard garden hose) and a flow of up to 3.5 GPM (CETA-certified values), resulting in the DeWalt DXPW4035's cleaning power of 14000 Cleaning Units.

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

Gasoline storage is facilitated by a fuel tank with a maximum capacity of 1.4 gallon.

Design & Handling

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

This model weighs 126 lbs. For this reason, it cannot be called lightweight and thus, carrying and transporting it might be somewhat challenging. Its 269cc Honda GX270 engine, the triplex pump and welded steel frame are mainly responsible for its heavy weight. However, the unit is manipulated smoothly thanks to its two 13" pneumatic wheels, which play a key role in its maneuverability.

Main Features

The DeWalt DXPW4035 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. If a soap nozzle is attached, the device will proceed to add the detergent to the water automatically.
  • Pressure hose: Using a set of convenient hooks, the included 50 ft ⌀3/8" high-pressure hose can be easily stored on the unit when it is not running.
  • Spray gun and wand: Both the classic ergonomic spray gun and its wand may be conveniently 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.

    Ease Of Use

    Bought a DeWalt DXPW4035 from Home Depot ($950.00) and used it three times. During the beginning of the 4th use the unit’s pump would not generate pressure or dispense a drop of water. I contacted Home Depot and was informed I had to directly contact a regional DeWalt service center for any repair. Home Depot provided no assistance so I researched and found the closest DeWalt Service Center to Tampa which was in Orlando (146 miles from my house). The DeWalt Service Center informed me they do not repair DeWalt Pressure Washer units because they do not produce them. Dewalt actually purchases the pressure washer units from a company named FNA and then they place their DeWalt logo on the units and sell them as if they were a Dewalt product. I called FNA for repair information and was instructed to take the unit to a local small engine repair shop in Tampa along with the Home Depot sales slip for a potential repair. Needless to say, I was informed that I would be given a call but that the repair could be over $1000 (a bit more than the purchase price of the unit. This was another lesson learned from 2 supposed legitimate companies (Home Depot and Dewalt) on how customers are mislead about products and can be scammed by clever marketing techniques.

    + PROS: Initially worked to specifications after purchase. Generated great power for home applications
    - CONS: Engine had power fluctuation after first use. Pump stopped working after third use. Dewalt does not make or service any pressure washers which carry their logo Home Depot had no clue the Dewalt Pressure Washer they are selling ARE NOT DeWalt products. The Dewalt Service Center in Orlando was worthless with addressing customer services requirement. The DXPW4035 is not worth the money it is sold for.

    Ease Of Use

    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

    Ease Of Use

    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.
