Key Features

The specifications of the Karcher G2900X Gas Pressure Washer are impressive for a domestic pressure washer, with a 2900 PSI, 2.4 GPM compressor and a 196 cc engine for high performance. The upright cart frame is made from durable steel with an anti-rust coating, all in a relatively compact 19 x 25.1 x 37-inch body for easy storage.

This gas pressure washer weighs a lightweight 66 lbs, far less than many other gas powered pressure washers of similar power and pressure. Overall, this is a good choice for domestic use on any scale, or potentially smaller commercial cleaning projects.


5 Interchangeable Spray Nozzles: The 5 different interchangeable spray nozzles included with the Karcher G2900X give it a high level of versatility and flexibility, offering spray angles from 0 degrees to a wide 65 degrees, or even simple detergent spraying functionality.

Small Storage Footprint: The upright cart design of this karcher pressure washer allows it to take up a relatively small footprint when stored; the majority of the space it occupies is vertical, rather than horizontal. This makes it a great choice for anyone with limited storage space available.

High Pressure: The high pressure produced by the 2900 PSI, 2.4 GPM compressor gives a high level of cleaning power, outstripping that of many other models of pressure washer from Karcher. This is an efficient cleaning product for even the most stubborn and ingrained outdoor dirt and grime.


Loud Engine: The 196 cc Karcher KPS engine of this model of karcher pressure washer operates at a higher volume than many other Karcher pressure washer models, but this is the price of higher powered gas pressure washers. It’s not a deal breaker, but a feature to be aware of if the volume is a particular concern when you’re looking for a gas pressure washer.

High Temperature: The engine of the Karcher G2900X Pressure Washer runs at a relatively high temperature. This is not a major problem in itself but requires a little management during extensive use. If the water hose of the pressure washer rests against the engine, which can occur during use, then the high temperature may be sufficient to melt the hose, damaging the pressure washer and requiring a replacement component.

Who Is It Suitable For?

The Karcher G2900X Gas Powered Pressure Washer is suitable for domestic use on any scale, cleaning gardens, the exteriors of houses, or even cars with ease. It is also appropriate for smaller commercial or industrial cleaning projects, although larger and higher pressure models will provide better performance for such intense and extensive use.

This is one of the best models of gas pressure cleaner for entry-level users, as it is easy to use and offers a high level of performance and cleaning power with minimal effort required. At Best of Machinery, we would recommend this model of gas pressure washer to anyone from beginners to intermediate users of gas pressure washers, but it’s also a great choice for more advanced users on a budget.
