Description

Zoom on the DeWalt DXPW4035

The DeWalt DXPW4035, a heavy duty, commercial pressure washer, gives its user an all-around versatile cleaning experience, topped off by the following features:

  • spot cleaning of hard, paint-free surfaces and out-of-reach areas
  • thorough cleaning of hard, paint-free surfaces
  • cleaning of painted and frail surfaces
  • use of detergent and cleaning solutions

Its power characteristics and design, its main features and all its additional features are presented ahead.

Power

With an impressive 270 cc (8.4 hp) engine, its triplex pump delivers a pressure of 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), resulting in the DeWalt DXPW4035's cleaning power of 14000 Cleaning Units.

The Honda GX270 engine of this gas-powered pressure washer relies on an old-school pull-start mechanism to get started.

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. The robust and sturdy welded steel frame offers longevity to the assembly. The handle adds to the DXPW4035 convenience of transport.

This model weighs 126 lbs. For this reason, it cannot be called lightweight and thus, carrying and transporting it might be somewhat challenging. Its 270 cc Honda GX270 engine, the triplex pump and welded steel frame add up to a large chunk of the device's weight. However, the unit is mobile thanks to its two 13" pneumatic wheels, which add to its movability and allow it to be manipulated smoothly on the job.

Main Features

Along with the DeWalt DXPW4035 itself, the package also includes a spray gun, a wand, a pressure hose, 5 nozzles and a detergent injection feature, which are discussed in further detail 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. A rotating auxiliary side handle further improves both left-handed and right-handed users' comfort.
  • Nozzles: The table below shows you the 5 included nozzles, as well as the surfaces they're the most appropriate for.

  • Safety: Safety of operation is enhanced by a trigger lock mechanism (which prevents accidental operation), a thermal relief valve (which helps to prevent internal pump damage) and a low oil protection.
  • Accessories: Included with the DeWalt DXPW4035 are also the owner's manual and some basic documentation to get you promptly started, along with several accessories, such as oil, soap hose, pressure hose, nozzle cleaner, spray gun and wand.
  • Emissions: The DeWalt DXPW4035 is EPA-approved and CARB-compliant. Thus, selling and purchasing this pressure washer is allowed in each of the 50 states, including California.

The DeWalt DXPW4035's performance versus other pressure washers

The following charts are provided to give you an idea of how the key specs of the DeWalt DXPW4035 compare to similarly priced pressure washers.

  • The DeWalt DXPW4035, which can reach up to 4000 PSI, has one of the higher pressure outputs of the gas-powered units that cost between $700 and $800. 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.
  • In its respective price range, the water flow of this washer, 3.5 GPM (gallons per minute), ranks as average. If you’re after the highest rinsing efficiency, one of the units with the highest water flow in the current price range is the Generac 6565, that can deliver up to 4 GPM.
  • The 14000 Cleaning Units (PSI x GPM), of the DXPW4035 result in an average cleaning efficiency, compared to similarly priced gas-powered units. In case you are looking for the highest overall cleaning power, in this price range, one of the current champions is the Pressure-Pro PP4440K and its 17600 Cleaning Units.

Price comparison

As you can see from this interactive chart, when compared to other gas-powered washers between 14000 and 14500 Cleaning Units, the DeWalt DXPW4035 is on the cheap side of the price range.

It can therefore be a really good buy if you're looking to acquire a budget pressure washer.
