Description

Zoom on the Generac XC4200W

The Generac XC4200W, 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, unpainted surfaces or high reach areas
  • thorough cleaning of hard, paint-free surfaces
  • cleaning of painted and fragile surfaces
  • applying detergent and cleaning solutions

Ahead are presented its power characteristics and design, its main features and any other additional features.

Power

Powered by an impressive 420 cc engine, its triplex pump can deliver a pressure of 4200 PSI (around 70 times more than a standard garden hose) and a flow of up to 4 GPM (values claimed by the manufacturer). Combined, these values mean that the Generac XC4200W has a cleaning power of 16800 Cleaning Units.

The Generac G-Force (opens in a new tab) engine of this gas-powered pressure washer gets started by a classic pull-start mechanism.

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 strong welded steel frame assures assembly longevity. 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 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, the unit’s three 10" never-flat wheels are crucial to its maneuverability, since they provide a smooth method of manipulation on the job.

Main Features

The Generac XC4200W comes with a spray gun, a wand, a pressure hose, 5 nozzles and a detergent injection feature, which are detailed 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 is automatically added to the water when a soap nozzle is connected.
  • Pressure hose: This washer 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 enables you to easily store the included classic ergonomic spray gun and its stainless steel wand. 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: With the Generac XC4200W's handy storage area, you’ll always have all the necessary nozzles and accessories at hand and thus, you’ll be fully prepared for any job.
  • Safety: Safety of operation is enhanced by a thermal relief valve (which helps to prevent internal pump damage), a low oil protection and a trigger lock mechanism (which prevents accidental operation).
  • Accessories: Included with the Generac XC4200W are also the owner's manual (opens in a new tab) and some basic documentation to get you promptly started, along with several accessories, such as soap hose, spray gun, pressure hose and wand.
  • Emissions: The Generac XC4200W is NOT CARB-compliant and so you cannot buy it nor sell it in California.
