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
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.
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.
