Zoom on the DeWalt DXPW4440
In summary, the DeWalt DXPW4440 is a heavy duty, commercial pressure washer, that offers an all-around versatile cleaning experience, and also:
- spot cleaning of hard, paint-free surfaces and out-of-reach areas
- intense cleaning of hard, unpainted surfaces
- cleaning of painted and fragile surfaces
- use of detergent and cleaning solutions
The DeWalt DXPW4440's triplex pump, powered by an impressive 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 (values claimed by the manufacturer). 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.
The fuel is stored in a tank, which can hold up to 1.6 gallon of gasoline.
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.
With a weight of 139 lbs, the model is not lightweight. Therefore, it may be challenging to manually carry it around and transport it. The major reasons for its heavy weight are 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: While the device doesn't feature a soap tank, detergent supply is ensured by a siphon hose. If a soap nozzle is attached, the device will proceed to add the detergent to the water automatically.
- 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: 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 following table illustrates the 5 included nozzles, along with the surfaces which they are the most suitable for.
