Zoom on the DeWalt DXPW4035
In summary, the DeWalt DXPW4035 is a heavy duty, commercial pressure washer, that offers an all-around versatile cleaning experience, and also:
- spot cleaning of hard, unpainted surfaces and high-reach cleaning
- intense cleaning of hard, unpainted surfaces
- cleaning of painted and fragile surfaces
- applying detergent and cleaning solutions
Using a powerful 270 cc (8.4 hp) engine, its triplex pump delivers a pressure of up to 4000 PSI (roughly 67 times more than a standard garden hose) and a flow of up to 3.5 GPM (values claimed by the manufacturer). Together, the values result in a cleaning power of 14000 Cleaning Units.
This gas-powered pressure washer’s Honda GX270 engine is started by a traditional pull-start mechanism.
A fuel tank with a maximum capacity of 1.4 gallon is used to store gasoline.
Design & Handling
The wheelbarrow design of the DeWalt DXPW4035 grants mobility and stability to the unit. Its sturdy welded steel frame provides longevity to the assembly. The handle adds to the DXPW4035 convenience of transport.
The unit's weight of 126 lbs renders its carrying and transportation challenging, as it is far from lightweight. The major reasons for its heavy weight are its 270 cc Honda GX270 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 DXPW4035'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: Detergent is fed in through a siphon hose, since the device lacks a soap tank. 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: The included classic ergonomic spray gun and its wand can be easily stored in a side hook. A rotating auxiliary side handle further improves both left-handed and right-handed users' comfort.
- Nozzles: The 5 included nozzles, and the respective surfaces they’re appropriate for, are listed in the table below.

- The DeWalt DXPW4035, reaching a PSI of up to 4000, is one of the more powerful gas-powered units in $675-825 price range. If your priority is the highest possible power of the water stream, in this price range, we suggest checking out the Pressure-Pro PP4440K, which reaches up to 4400 PSI.
- With a water flow of up to 3.5 GPM (gallons per minute), this washer belongs to the upper end of the above-mentioned price range, as it can deliver a high volume of water. In case you are looking for a device which can most efficiently rinse away debris in the current price range, the Generac 6565 has the highest GPM of 4.
- Boasting with 14000 Cleaning Units (PSI x GPM), the DXPW4035 is one of the more efficient devices in its respective price range.
