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

In a nutshell, the DeWalt DXPW4440 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
  • thorough cleaning of hard, paint-free surfaces
  • cleaning of painted or delicate surfaces
  • applying detergent and cleaning solutions

Ahead are presented its power characteristics and design, its main features and any other additional features.

Power

The DeWalt DXPW4440 in use

The DeWalt DXPW4440

The DeWalt DXPW4440's triplex pump, powered by a powerful 389 cc (11.7 hp) engine, can provide a pressure of up to 4400 PSI (approximately 73 times more than a standard garden hose) and a flow of up to 4 GPM (CETA-certified values). The DeWalt DXPW4440 thus has a cleaning power of 17600 Cleaning Units.

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

Gasoline storage is facilitated by a fuel tank with a maximum capacity of 1.6 gallon.

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

The DeWalt DXPW4440 comes with a spray gun, a wand, a pressure hose, 5 nozzles and a detergent injection feature, which are detailed below.

  • Soap injection: Detergent is fed in through a siphon hose, since the device lacks a soap tank. The detergent is automatically added to the water when a soap nozzle is connected.
  • 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.

    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.
