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 tough, paintless surfaces
  • cleaning of painted and fragile 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.

Power

With a powerful 389 cc (11.7 hp) engine, its triplex pump delivers a pressure of 4400 PSI (roughly 73 times more than a standard garden hose) and a flow of up to 4 GPM (values claimed by the manufacturer), resulting in the DeWalt DXPW4440's 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 strong welded steel frame assures assembly longevity. 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. A key role in its final weight is played by its 389 cc Honda GX390 engine, the triplex pump and welded steel frame. However, the unit is manipulated smoothly thanks to its two 13" pneumatic wheels, which play a key role in its maneuvrability.

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: Even though the device doesn't have a soap tank, detergent is supplied 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 included nozzles, and the respective surfaces they’re appropriate for, are listed in the table below.

Other Features

  • Onboard storage: Stay prepared for any job with DeWalt DXPW4440's handy storage area, which allows you to neatly store any nozzles and accessories which you may need for the job.
  • 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 wand, spray gun, pressure hose, soap hose, nozzle cleaner and oil.
  • Emissions: The DeWalt DXPW4440 is EPA-approved and CARB-compliant. And so, this pressure washer is available for sale and purchase in any of the 50 states, including California.

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 the highest pressure, amongst the gas-powered products that cost between $800 and $900.
  • Considering the above-mentioned price range, this washer's maximum water flow of 4 GPM (gallons per minute) is higher than the average. If being able to rinse away debris as efficiently as possible is your priority, one of the products with the highest GPM in this price range is the Predator 4400, with 4.2 GPM.
  • Boasting with 17600 Cleaning Units (PSI x GPM), the DXPW4440 is one of the more efficient devices in its respective price range. If the highest overall cleaning power is your top priority, the Predator 4400, which can reach up to 18480 Cleaning Units, is one of the most efficient of the devices in the current price range.

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 average side of the price range.

Therefore, this pressure washer nicely fits in the expected budget for this kind of cleaning power.
