Description

Zoom on the Generac XC4200W

In a nutshell, the Generac XC4200W 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, unpainted surfaces and high-reach cleaning
  • 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

Using an impressive 420 cc engine, its triplex pump delivers a pressure of up to 4200 PSI (roughly 70 times more than a standard garden hose) and a flow of up to 4 GPM (values claimed by the manufacturer). Together, the values result in a cleaning power of 16800 Cleaning Units.

A classic pull-start mechanism is responsible for starting the gas-powered pressure washer’s Generac G-Force (opens in a new tab) engine.

A steel fuel tank with a maximum capacity of 1.6 gallon is used to store gasoline.

Design & Handling

The wheelbarrow design of the Generac XC4200W grants mobility and stability to the unit. The robust welded steel frame guarantees longevity of the assembly. The folding handle enhances its mobility, while allowing for a convenient storage.

The unit's weight of 151 lbs renders its carrying and transportation challenging, as it is far from lightweight. A key role in its final weight is played by its 420 cc Generac G-Force engine, the triplex pump and welded steel frame. However, its three 10" never-flat wheels play an important part in its maneuvrability, as they allow for a smooth manipulation on the job.

Main Features

Along with the Generac XC4200W 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: The XC4200W does not feature a traditional soap tank. Instead, the detergent is supplied by a siphon hose. For this purpose, it has an integrated 5 gallon bucket holder that can hold cleaning detergent or serve as an additional onboard storage for tools and accessories. This bucket holder can be folded to save storage space. When a soap nozzle is connected, the detergent will be added automatically to the water.
  • Pressure hose: An easy-to-connect 35 ft ⌀3/8" high-pressure hose (4200 PSI rating) is included with the unit. But, there is no proper storage solution designed for it (no reel, strap or hook).
  • Spray gun and wand: Both the classic ergonomic spray gun and its stainless steel 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 table below shows you the 5 included nozzles, as well as the surfaces they're the most appropriate for.

Other Features

  • Onboard storage: The Generac XC4200W's handy storage area lets you store nozzles and accessories, and thus, you’ll be always prepared and have everything necessary for the job at hand.
  • Safety: Safety of operation is enhanced by a thermal relief valve (which helps to prevent internal pump damage), a trigger lock mechanism (which prevents accidental operation) and a low oil protection.
  • Accessories: Besides the usual owner's manual (opens in a new tab) and documentation to get you promptly started, the Generac XC4200W comes with spray gun, pressure hose, soap hose and wand.
  • Emissions: The Generac XC4200W is NOT CARB-compliant. Therefore, it is not available in California for sale nor purchase.

The Generac XC4200W's performance versus other pressure washers

The following charts are provided to give you an idea of how the key specs of the Generac XC4200W compare to similarly priced pressure washers.

  • The Generac XC4200W, with a max water pressure of 4200 PSI, has one of the highest PSI values of the gas-powered products in the $1150-1400 price range.
  • In the aforementioned price range, the 4 GPM (gallons per minute) of this washer makes it one of the best performing units in terms of the delivered volume of water.
  • The XC4200W, which reaches up to 16800 Cleaning Units (PSI x GPM) is one of the most efficient, in comparison to its similarly priced counterparts.

Price comparison

As you can see from this interactive chart, when compared to other gas-powered washers between 16500 and 17000 Cleaning Units, the Generac XC4200W 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.
