Description

This high-performance 4400 PSI 4.0 GPM Cold Water Gas Pressure Washer features a triplex pump and a 389cc Honda® GX390 engine to drive its powerful operation. (source: DeWalt (opens in a new tab))

Zoom on the DeWalt DXPW4440

The DeWalt DXPW4440 is a heavy duty, commercial pressure washer, that provides its users with an all-around versatile cleaning experience, and enables:

  • 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

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

Power

The DeWalt DXPW4440 in use

The DeWalt DXPW4440

Using an impressive 389 cc (11.7 hp) engine, its triplex pump delivers a pressure of up to 4400 PSI (roughly 73 times more than a standard garden hose) and a flow of up to 4 GPM (CETA-certified values). Together, the values result in a cleaning power of 17600 Cleaning Units.

This gas-powered pressure washer’s Honda GX390 engine is started by a traditional pull-start mechanism.

A fuel tank with a maximum capacity of 1.6 gallon is used to store gasoline.

Design & Handling

The wheelbarrow design of the DeWalt DXPW4440 grants mobility and stability to the unit. The robust and sturdy welded steel frame offers longevity to the assembly. The handle adds to the DXPW4440 convenience of transport.

The unit's weight of 139 lbs renders its carrying and transportation challenging, as it is far from lightweight. The major reasons for its heavy weight are its 389 cc Honda GX390 engine, the triplex pump and welded steel frame. However, its two 13" pneumatic wheels play an important part in its maneuverability, as they allow for a smooth manipulation on the job.

Main Features

Along with the DeWalt DXPW4440 itself, the package also includes a spray gun, a wand, a pressure hose, 5 nozzles and a detergent injection feature, which are discussed in further detail below.

  • Soap injection: While the device doesn't feature a soap tank, detergent supply is ensured by a siphon hose. 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. The gun features a rotating auxiliary side handle to further improve the comfort of both left and right-handed users.
  • Nozzles: The table below shows you the 5 included nozzles, as well as the surfaces they're the most appropriate for.

Some of the included accessories

  • Onboard storage: The DeWalt DXPW4440's handy storage area lets you store nozzles and accessories, and thus, you’ll be always prepared and have everything necessary for the job at hand.
  • Safety: Safety of operation is enhanced by a thermal relief valve (which helps to prevent internal pump damage), a low oil protection and a trigger lock mechanism (which prevents accidental operation).
  • Accessories: The DeWalt DXPW4440 comes with an owner's manual and some basic documentation to get you quickly started. On top of that, you also get soap hose, nozzle cleaner, spray gun, wand, oil and pressure hose.

The DeWalt DXPW4440's performance versus other pressure washers

The following charts are provided to give you an idea of how the key specs of the DeWalt DXPW4440 compare to similarly priced pressure washers.

  • With 4400 PSI, the DeWalt DXPW4440 ranks as one that can reach an above average pressure, amongst the gas-powered products that cost between $1000 and $1300. If the highest possible power of the water stream is your priority, one of the champions in this price range is the Lifan LFQ4515E-CA with 4500 PSI.
  • In the aforementioned price range, the 4 GPM (gallons per minute) of this washer makes it one of the best performing units in terms of the delivered volume of water.
  • The DXPW4440, which reaches up to 17600 Cleaning Units (PSI x GPM) is one of the more efficient, in comparison to its similarly priced counterparts. If you consider the highest overall cleaning power as a really important factor, the Lifan LFQ4515E-CA and its 18000 Cleaning Units has one of the highest cleaning efficiency of all the similarly priced units.

Price comparison

As you can see from this interactive chart, when compared to other gas-powered washers between 17500 and 18000 Cleaning Units, the DeWalt DXPW4440 is on the expensive side of the price range.

While certainly not the cheapest of its cleaning power range, purchasing it could most likely also mean enjoying the reliability of a high-end product.

    Bought it and in third use the pump leaked all of its oil thru the see-thru gauge on the front. Disappointed.

    + PROS: Great pressure. Nice gun and nozzles.
    - CONS: Pump leaked all of its oil on third light use.

    I have 3 DeWalt 4400,4200, and 4000 PSI pressure washers. I also have a Husqvarna 3200.
    The DeWalt units have been great for the past three years.

    + PROS: Durable, They do a great job.
    - CONS: Heavy, Connections have to be serviced frequently to keep from leaking. Not a problem. O rings and washers replaced takes care of the problem.
