Zoom on the Kärcher G2900X

The Kärcher G2900X, a heavy duty pressure washer, gives its user an all-around versatile cleaning experience, topped off by the following features:

  • intense cleaning of hard, unpainted surfaces
  • cleaning of painted or delicate surfaces
  • application of detergent and cleaning solutions

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

Power

With a 196 cc engine, its axial pump delivers a pressure of 2900 PSI (roughly 48 times more than a standard garden hose) and a flow of up to 2.4 GPM (CETA-certified values), resulting in the Kärcher G2900X's cleaning power of 6960 Cleaning Units.

The Kärcher KPS engine of this gas-powered pressure washer relies on an old-school pull-start mechanism to get started.

A fuel tank with a maximum capacity of 0.4 gallon is used to store gasoline.

Design & Handling

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

Weighing 63 lbs, the unit is easy to maneuver by most people. A major component of its weight are its 196 cc Kärcher KPS engine and welded steel frame. Since the G2900X has a set of two 12" never-flat wheels, it is still easily maneuvered and manipulated.

Main Features

The Kärcher G2900X's package includes a spray gun, a wand, a pressure hose, 4 nozzles and a detergent injection feature, with a more detailed description below.

  • Soap injection: A safe detergent storage is facilitated 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. The detergent will be added automatically to the water when a soap nozzle is attached.
  • 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: Both the classic ergonomic spray gun and its zinc-coated wand may be conveniently stored in a side hook.
  • Nozzles: The following table illustrates the 4 included nozzles, along with the surfaces which they are the most suitable for.

  • Accessories: The Kärcher G2900X comes with an owner's manual and some basic documentation to get you quickly started. On top of that, you also get pressure hose, spray gun and wand.
  • 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.

  • With its 2900 PSI max pressure output, the Karcher G2900X is in the expected pressure range, for gas-powered units in the $240-300 price range. In case you are looking for a device with the highest possible power of its water stream, one of the top achievers in this price range is the Westinghouse WPX3200 with a PSI of 3200.
  • In its respective price range, the water flow of this washer, 2.4 GPM (gallons per minute), ranks as average. If you’re after the highest rinsing efficiency, one of the units with the highest water flow in the current price range is the Excell EPW2123100, that can deliver 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 are after the highest overall cleaning power, the Excell EPW2123100 with its 8680 Cleaning Units is one of the products that can achieve the highest cleaning efficiency in this price range.
