Description

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, paintless surfaces and reaching far-away areas
  • intense cleaning of hard, unpainted surfaces
  • cleaning of painted and frail surfaces
  • application of detergent and cleaning solutions

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

Power

Using a powerful 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 (values claimed by the manufacturer). Together, the values result in a cleaning power of 17600 Cleaning Units.

The Honda GX390 engine of this gas-powered pressure washer gets started by a classic 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. Its sturdy welded steel frame provides longevity to the assembly. The handle adds to the DXPW4440 convenience of transport.

This model weighs 139 lbs. For this reason, it cannot be called lightweight and thus, carrying and transporting it might be somewhat challenging. Its 389 cc Honda GX390 engine, the triplex pump and welded steel frame add up to a large chunk of the device's weight. However, the unit’s two 13" pneumatic wheels are crucial to its maneuvrability, since they provide a smooth method of manipulation on the job.

Main Features

The DeWalt DXPW4440'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 though the device doesn't have a soap tank, detergent is supplied by a siphon hose. The detergent will be added automatically to the water when a soap nozzle is attached.
  • Pressure hose: A neat storage for the included 50 ft ⌀3/8" high-pressure hose is facilitated by a set of convenient hooks.
  • Spray gun and wand: A side hook enables you to easily store 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 following table illustrates the 5 included nozzles, along with the surfaces which they are the most suitable for.

  • Accessories: Besides the usual owner's manual and documentation to get you promptly started, the DeWalt DXPW4440 comes with soap hose, spray gun, nozzle cleaner, pressure hose, oil and wand.
  • Emissions: The DeWalt DXPW4440 is EPA-approved and CARB-compliant. Thus, selling and purchasing this pressure washer is allowed in each of the 50 states, including California.
