The Kärcher G3100XH is a gas-powered pressure washer offering a maximum water pressure of 3100 PSI and flow of 2.4 GPM. (Read full specs)
Zoom on the Kärcher G3100XH
In summary, the Kärcher G3100XH is a heavy duty, commercial pressure washer, that offers an all-around versatile cleaning experience, and also:
- thorough cleaning of hard, paint-free surfaces
- cleaning of painted and fragile surfaces
- application of detergent and cleaning solutions
With a 187 cc (6 hp) engine, its axial pump delivers a pressure of 3100 PSI (roughly 52 times more than a standard garden hose) and a flow of up to 2.4 GPM (values claimed by the manufacturer), resulting in the Kärcher G3100XH's cleaning power of 7440 Cleaning Units.
A classic pull-start mechanism is responsible for starting the gas-powered pressure washer’s Honda GC190 engine.
The fuel is stored in a tank, which can hold up to 0.48 gallon of gasoline.
Design & Handling
With its hand truck design and approximate dimensions of D25 x W19 x H37 in, the Kärcher G3100XH provides great mobility. The robust welded steel frame guarantees longevity of 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. One of the largest contributors to its weight are its 187 cc Honda GC190 engine and its welded steel frame. However, the two 12" never-flat wheels allow the G3100XH to be easily manipulated and maneuvered.
Along with the Kärcher G3100XH 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: A safe detergent storage is facilitated by a removable 0.5 gal tank. As the Kärcher G3100XH doesn’t include a soap dilution mechanism, the user must provide a correctly diluted detergent before proceeding to use it. When a soap nozzle is connected, the detergent will be added automatically to the water.
- Pressure hose: The 25 ft ⌀1/4" high-pressure hose, which is included with the device, can be stored neatly on the unit itself when idle, using a set of easy-to-use straps.
- Spray gun and wand: The included VersaGRIP spray gun and its zinc-coated wand can be easily stored in a side hook.
- Nozzles: The table below shows you the 4 included nozzles, as well as the surfaces they're the most appropriate for.

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.
- Onboard storage: The Kärcher G3100XH allows you to be always fully prepared, as it features a handy storage area, where nozzles and accessories can be stored.
- Safety: Safety of operation is enhanced by a trigger lock mechanism (which prevents accidental operation).
- Accessories: Besides the usual owner's manual (opens in a new tab) and documentation to get you promptly started, the Kärcher G3100XH comes with spray gun, pressure hose and wand.
- Emissions: The Kärcher G3100XH is NOT CARB-compliant. Thus, it cannot be purchased or sold 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 you're going after the highest possible power of the water stream, one of the best in this price range is the Briggs & Stratton 20647 that can reach up to 3600 PSI.
- This washer reaches 2.4 GPM (gallons per minute) and thus, has an average water flow compared to similarly priced devices. If maximum rinsing efficiency is your top priority, one of the devices with the highest water flow in the same price range is the Lifan LFQ3370, with a GPM of 3.
- The 7440 Cleaning Units (PSI x GPM), of the G3100XH sit at an average, in reference to other gas-powered units of similar price. When it comes to the highest overall cleaning power in the current price range, one of the products at the very top currently is the Lifan LFQ3370 and its 9900 Cleaning Units.
As you can see from this interactive chart, when compared to other gas-powered washers between 7000 and 7500 Cleaning Units, the Karcher G3100XH 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.
