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
- intense cleaning of hard, unpainted surfaces
- cleaning of painted and frail surfaces
- use of detergent and cleaning solutions
Its triplex pump, which utilizes a powerful 420cc engine, may deliver a pressure of up to 4200 PSI (almost 70 times more than a standard garden hose) and a flow of up to 4 GPM. These values correspond to a cleaning power of 16800 Cleaning Units.
Gasoline storage is facilitated by a steel fuel tank with a maximum capacity of 1.6 gallon.
Design & Handling
The wheelbarrow design of the Generac XC4200W grants mobility and stability to the unit. Its sturdy welded steel frame provides longevity to 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. Its 420cc Generac G-Force engine, the triplex pump and welded steel frame are mainly responsible for its heavy weight. However, the unit is mobile thanks to its three 10" never-flat wheels, which add to its movability and allow it to be manipulated smoothly on the job.
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. If a soap nozzle is attached, the device will proceed to add the detergent to the water automatically.
- Pressure hose: The unit comes with an easy-to-connect 35 ft ⌀3/8" high-pressure hose (4200 PSI rating). But, there is no proper storage solution designed for it (no reel, strap or hook).
- Spray gun and wand: A side hook allows for an easy storage of the included classic ergonomic spray gun and its stainless steel wand. 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.

- Onboard storage: The Generac XC4200W features a handy storage area, which allows you to neatly store nozzles and accessories and be always prepared by having everything needed at hand.
- 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: On top of an owner's manual (opens in a new tab) and the usual documentation to get you swiftly started, the Generac XC4200W also comes with soap hose, pressure hose, wand and spray gun.
- Emissions: The Generac XC4200W is NOT CARB-compliant. Thus, it cannot be purchased or sold in California.
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.
- With 4200 PSI, the Generac XC4200W ranks as one that can reach the highest pressure, amongst the gas-powered products that cost between $1450 and $2200.
- 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.
- With a rather impressive value of 16800 Cleaning Units (PSI X GPM), the XC4200W has one of the highest cleaning efficiencies compared to similarly priced devices.
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 expensive side of the price range.
While certainly not the cheapest of its cleaning power range, purchasing it could most likely also mean enjoying the reliability of a high-end product.
