Zoom on the Generac XC4200W
In summary, the Generac XC4200W is a heavy duty, commercial pressure washer, that offers an all-around versatile cleaning experience, and also:
- spot cleaning of hard, unpainted surfaces or high reach areas
- intense cleaning of tough, paintless surfaces
- cleaning of painted and frail surfaces
- application of detergent and cleaning solutions
Ahead are presented its power characteristics and design, its main features and any other additional features.
The Generac XC4200W's triplex pump, powered by a powerful 420 cc engine, can provide a pressure of up to 4200 PSI (approximately 70 times more than a standard garden hose) and a flow of up to 4 GPM (values claimed by the manufacturer). The Generac XC4200W thus has a cleaning power of 16800 Cleaning Units.
This gas-powered pressure washer’s Generac G-Force (opens in a new tab) engine is started by a traditional pull-start mechanism.
The fuel is stored in a steel tank, which can hold up to 1.6 gallon of 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.
With a weight of 151 lbs, the model is not lightweight. Therefore, it may be challenging to manually carry it around and transport it. Its 420 cc Generac G-Force engine, the triplex pump and welded steel frame add up to a large chunk of the device's weight. However, its three 10" never-flat wheels play an important part in its maneuverability, as they allow for a smooth manipulation on the job.
The Generac XC4200W'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: 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. The detergent will be added automatically to the water when a soap nozzle is attached.
- 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: The included classic ergonomic spray gun and its stainless steel 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.

- 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 trigger lock mechanism (which prevents accidental operation), a thermal relief valve (which helps to prevent internal pump damage) and a low oil protection.
- Accessories: The Generac XC4200W comes with an owner's manual (opens in a new tab) and some basic documentation to get you quickly started. On top of that, you also get pressure hose, spray gun, soap hose and wand.
- Emissions: The Generac XC4200W is NOT CARB-compliant. Therefore, it is not available in California for sale nor purchase.
