Zoom on the Kärcher G2900X

In summary, the Kärcher G2900X is a heavy duty pressure washer, that offers an all-around versatile cleaning experience, and also:

  • intense cleaning of hard, unpainted surfaces
  • cleaning of painted or delicate surfaces
  • applying 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 196 cc engine, its axial pump delivers a pressure of up to 2900 PSI (roughly 48 times more than a standard garden hose) and a flow of up to 2.4 GPM (values claimed by the manufacturer). Together, the values result in a cleaning power of 6960 Cleaning Units.

The Kärcher KPS engine of this gas-powered pressure washer gets started by a classic pull-start mechanism.

Gasoline storage is facilitated by a fuel tank with a maximum capacity of 0.4 gallon.

Design & Handling

With its hand truck design and approximate dimensions of D21.5 x W20 x H35 in, the Kärcher G2900X provides great mobility. The robust and sturdy welded steel frame offers longevity to the assembly. The folding handle enhances its mobility, while allowing for a convenient storage.

The majority of users will be able to maneuver this unit easily, it only weighs 63 lbs. Its 196 cc Kärcher KPS engine and welded steel frame all add up to a substantial part of that weight. However, the two 12" never-flat wheels allow the G2900X to be easily manipulated and maneuvered.

Main Features

Along with the Kärcher G2900X itself, the package also includes a spray gun, a wand, a pressure hose, 4 nozzles and a detergent injection feature, which are discussed in further detail below.

  • Soap injection: Detergent storage is ensured by a removable 0.5 gal tank. The Kärcher G2900X is not equipped with a soap dilution mechanism, and thus, it is up to the user to ensure the detergent’s correct dilution ratio when using it. If a soap nozzle is attached, the device will proceed to add the detergent to the water automatically.
  • Pressure hose: Using a set of easy-to-use straps, the included 25 ft ⌀1/4" high-pressure hose can be easily stored on the unit when it is not running.
  • Spray gun and wand: A side hook allows for an easy storage of the included classic ergonomic spray gun and its zinc-coated wand.
  • Nozzles: The following table illustrates the 4 included nozzles, along with the surfaces which they are the most suitable for.

  • Accessories: Besides the usual owner's manual and documentation to get you promptly started, the Kärcher G2900X comes with wand, spray gun and pressure hose.
  • Emissions: The Kärcher G2900X is CARB-compliant. Therefore, its sale and purchase are permitted in all of the 50 states, including California.

The Kärcher G2900X's performance versus other pressure washers

The following charts are provided to give you an idea of how the key specs of the Kärcher G2900X compare to similarly priced pressure washers.

  • The Karcher G2900X with its 2900 PSI achieves a lower pressure value, compared to other gas-powered pressure washers in the $300-400 price range. If you're going after the highest possible power of the water stream, one of the best in this price range is the Westinghouse WPX3400 that can reach up to 3400 PSI.
  • This washer reaches 2.4 GPM (gallons per minute) and thus, has an average water flow compared to similarly priced devices. If rinsing away debris most efficiently is your priority, one of the devices with the highest GPM in this price range is the Predator 3100, which can reach up to 2.8 GPM.
  • The 6960 Cleaning Units (PSI x GPM), of the G2900X sit at an average, in reference to other gas-powered units of similar price. If you consider the highest overall cleaning power as a really important factor, the Predator 3200 and its 8960 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 6500 and 7000 Cleaning Units, the Karcher G2900X 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.
