Zoom on the Kärcher G3100XH

The Kärcher G3100XH is a heavy duty, commercial pressure washer, that provides its users with an all-around versatile cleaning experience, and enables:

  • intense cleaning of tough, paintless surfaces
  • cleaning of painted or delicate surfaces
  • use of detergent and cleaning solutions

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

Power

Its axial pump, which utilizes a 187 cc (6 hp) engine, may deliver a pressure of up to 3100 PSI (almost 52 times more than a standard garden hose) and a flow of up to 2.4 GPM. These values correspond to a cleaning power of 7440 Cleaning Units.

The Honda GC190 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 0.48 gallon.

Design & Handling

The Kärcher G3100XH offers superb mobility, with a hand truck design and approximate dimensions of D25 x W19 x H37 in. The robust welded steel frame guarantees longevity of 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 65 lbs. Its 187 cc Honda GC190 engine and welded steel frame account for a good chunk of that weight. However, the two 12" never-flat wheels allow the G3100XH to be easily manipulated and maneuvered.

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. The Kärcher G3100XH 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 is automatically added to the water when a soap nozzle is connected.
  • Pressure hose: A neat storage for the included 25 ft ⌀1/4" high-pressure hose is facilitated by a set of easy-to-use straps.
  • Spray gun and wand: A side hook allows for an easy storage of the included VersaGRIP spray gun and its zinc-coated wand.
  • Nozzles: The 4 included nozzles, and the respective surfaces they’re appropriate for, are listed in the table below.

VersaGRIP Gun

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 wand, spray gun and pressure hose.
  • Emissions: The Kärcher G3100XH is NOT CARB-compliant and so you cannot buy it nor sell it in California.

The Kärcher G3100XH's performance versus other pressure washers

The following charts are provided to give you an idea of how the key specs of the Kärcher G3100XH compare to similarly priced pressure washers.

  • 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. If your priority is the highest possible power of the water stream, in this price range, we suggest checking out the Ryobi RY803423H, which reaches up to 3400 PSI.
  • Considering its water flow, this washer, with a GPM (gallons per minute) of 2.4 is in the average compared to other devices in its price range. If you’re after the highest rinsing efficiency, one of the units with the highest water flow in the current price range is the Predator 3100, that can deliver up to 2.8 GPM.
  • In comparison to other gas-powered units of similar price, the 7440 Cleaning Units (PSI X GPM) of the G3100XH are average. If you consider the highest overall cleaning power as a really important factor, the Predator 3100 and its 8680 Cleaning Units has one of the highest cleaning efficiency of all the similarly priced units.
