Description

Zoom on the Generac XC4200W

The Generac XC4200W is a heavy duty, commercial pressure washer, that provides its users with an all-around versatile cleaning experience, and enables:

  • spot cleaning of hard, unpainted surfaces and high-reach cleaning
  • intense cleaning of tough, paintless surfaces
  • cleaning of painted or delicate surfaces
  • application of detergent and cleaning solutions

The following sections will present you in detail its power characteristics and design, its main features and all the additional features it has to offer.

Power

Using a powerful 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.

This gas-powered pressure washer’s Generac G-Force (opens in a new tab) engine is started by a traditional pull-start mechanism.

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. The robust and sturdy welded steel frame offers longevity to the assembly. The folding handle enhances its mobility, while allowing for a convenient storage.

At 151 lbs, we can't really say that the unit is a lightweight, and manually lifting or transporting it could be a challenge. 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 is manipulated smoothly thanks to its three 10" never-flat wheels, which play a key role in its maneuvrability.

Main Features

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. Whenever a soap nozzle is connected, the detergent is automatically added to the water.
  • Pressure hose: This washer comes with an easy-to-connect 35 ft ⌀3/8" high-pressure hose (4200 PSI rating). However, it doesn't feature any proper storage solution 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 5 nozzles included with the device, and the respective surfaces which they’re the most suitable for, are shown in the following table.

Other Features

  • 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 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 and so you cannot buy it nor sell it 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.

  • The Generac XC4200W, reaching a PSI of up to 4200, is one of the more powerful gas-powered units in $1150-1500 price range. If the highest possible power of the water stream is your priority, one of the champions in this price range is the Lifan LFQ4515E-Elite with 4500 PSI.
  • The water flow of this washer, which reaches up to 4 GPM (gallons per minute) is one of the highest values found in the above-mentioned price range.
  • Boasting with 16800 Cleaning Units (PSI x GPM), the XC4200W is one of the more efficient devices in its respective price range. If you consider the highest overall cleaning power as a really important factor, the Lifan LFQ4515E-Elite and its 18000 Cleaning Units has one of the highest cleaning efficiency of all the similarly priced units.

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.
