Zoom on the Kärcher G3100XH

The Kärcher G3100XH, a heavy duty, commercial 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 and frail surfaces
  • application of detergent and cleaning solutions

Its power characteristics and design, its main features and all its additional features are presented ahead.

Power

Powered by a 187 cc (6 hp) engine, its axial pump can deliver a pressure of 3100 PSI (around 52 times more than a standard garden hose) and a flow of up to 2.4 GPM (values claimed by the manufacturer). Combined, these values mean that the Kärcher G3100XH has a cleaning power of 7440 Cleaning Units.

This gas-powered pressure washer’s Honda GC190 engine is started by a traditional pull-start mechanism.

Gasoline is stored in a fuel tank with a maximum capacity of 0.48 gallon.

Design & Handling

With its hand truck design and approximate dimensions of D25 x W19 x H37 in, the Kärcher G3100XH provides great mobility. Its sturdy welded steel frame provides longevity to the assembly. The folding handle enhances its mobility, while allowing for a convenient storage.

The device can be maneuvered with ease by most, since it only weighs 65 lbs. Its 187 cc Honda GC190 engine and welded steel frame account for a good chunk of that weight. Since the G3100XH has a set of two 12" never-flat wheels, it is still easily maneuvered and manipulated.

Main Features

The Kärcher G3100XH comes with a spray gun, a wand, a pressure hose, 4 nozzles and a detergent injection feature, which are detailed below.

  • Soap injection: A safe detergent storage is facilitated by a removable 0.5 gal tank. However, since the Kärcher G3100XH does not feature a soap dilution mechanism, you'll have to make sure your detergent is correctly diluted before use. 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: A side hook enables you to easily store the included VersaGRIP spray gun and its zinc-coated wand.
  • Nozzles: The 4 nozzles included with the device, and the respective surfaces which they’re the most suitable for, are shown in the following table.

VersaGRIP Gun

https://www.youtube.com/watch?v=8i367vouuPU

The VersaGRIP trigger gun has dual action triggers, which allow you to effectively use it at any angle. A shoulder stock lets you utilize your very own body as an anchor, creates a secure holding position and reduces any strain exerted on your fingers, hand and wrists during the cleaning. The VersaGRIP is compatible with many brands and models of gas pressure washers, as it can be easily attached to industry-standard standardized high pressure hoses and spray wands.

Other Features

  • Onboard storage: Stay prepared for any job with Kärcher G3100XH's handy storage area, which allows you to neatly store any nozzles and accessories which you may need for the job.
  • Safety: Safety of operation is enhanced by a trigger lock mechanism (which prevents accidental operation).
  • Accessories: On top of an owner's manual (opens in a new tab) and the usual documentation to get you swiftly started, the Kärcher G3100XH also comes with spray gun, wand and pressure hose.
  • Emissions: The Kärcher G3100XH is EPA-approved and CARB-compliant. Thus, selling and purchasing this pressure washer is allowed in each of the 50 states, including California.

  • With its 3100 PSI max pressure output, the Karcher G3100XH is in the expected pressure range, for gas-powered units in the $400-500 price range.

  • This washer, with a GPM of 2.4 (gallons per minute) has a somewhat lower water flows value compared to devices in its price range. If being able to rinse away debris as efficiently as possible is your priority, one of the products with the highest GPM in this price range is the Lifan LFQ3370E, with 3 GPM.
  • Amongst similarly priced gas-powered devices, the 7440 Cleaning Units (PSI x GPM) of the G3100XH rank as low.
