Power

The DeWalt DXPW4035 in use

The DeWalt DXPW4035

With a powerful 269cc (8.4 hp) engine powering it, the triplex pump of this unit are capable of achieving a pressure of 4000 PSI (approximately 67 times greater than that of a standard garden hose) and a flow rate of up to 3.5 GPM (CETA-certified values). Corresponding to these values is a cleaning power of 14000 Cleaning Units.

To initiate the Honda GX270 engine of this gas-powered pressure washer, a traditional pull-start mechanism is employed.

Fuel for the pressure washer is housed in a tank capable of holding up to 1.4 gallon of gasoline..

Design & Handling

With its wheelbarrow-inspired design, the DeWalt DXPW4035 aims for excellent mobility and stability, enabling effortless maneuvering and dependable performance across diverse environments. Guaranteeing longevity, the robust welded steel frame offers stability and protects internal components, even when subjected to demanding tasks. The handle adds to the DXPW4035 convenience of transport.

With its weight clocking in at 126 lbs, this unit's heftiness can't be ignored, presenting significant difficulties for users who need to lift and transport it, especially over uneven terrain. The major reasons for its heavy weight are its 269cc Honda GX270 engine, the triplex pump and welded steel frame. However, the incorporation of two 13" pneumatic wheels makes navigating the DXPW4035 less cumbersome, even on uneven terrain.

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: Even without a built-in soap tank, the device relies on a siphon hose to provide detergent. Upon attaching a soap nozzle, the pressure washer seamlessly integrates the detergent into the water flow.
  • Pressure hose: When not in use, the unit allows for tidy storage of the included 50 ft ⌀3/8" high-pressure hose using a set of convenient hooks, ensuring convenient organization.
  • Spray gun and wand: A side hook enables you to easily store 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: Review the table below to learn about the 5 included nozzles and the surfaces they're recommended for.

    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.

    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

    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.
