Karcher Pressure Washer Buyer’s Guide

A Karcher pressure washer makes light work of cleaning cars to bikes, garden furniture to garden paving, patios, or decking. Pressure washers use less water than a garden hose when doing the same jobs. 

To get an idea of what you want from a pressure washer, write down a list of jobs that would benefit from using a pressure washer around the home. By cross-referencing the tasks to the list of choices, you will find a model that will suit your needs.

Below we have set out certain factors to consider before buying a Karcher pressure washer.

Gas or Electric?

Gas and electric washers pressurize water differently, speed and strength being the most significant difference. Gas-powered pressure washers are usually louder than electric ones but produce more power. Electric pressure washers are quieter but typically have less power. Electric pressure washers are suitable for cleaning small areas fast and efficiently. Larger sizes can be covered but will take more time than the gas pressure washer.

 However, electric pressure washers are an ideal choice for use around the home. An extension lead will improve the range of the machine. With more power, the gas pressure washer tackles heavy-duty jobs and covers more significant areas such as driveways, decks, and homes with minimal effort in less time. These pressure washers are an ideal choice for contractors or landscapers and people experienced in using a pressure washer.


Pressure is essential and will depend on your needs. The pressure shows in two ways; PSI (pounds per square inch) and GPM (gallons per minute). The higher the PSI, the higher the power of a pressure washer. 

As a guide, if you use a pressure washer only once in a while for cleaning cars, bikes, fences, patios, garden furniture, etc., pressure washers up to 2,000 psi would be ideal. In contrast, if you are using a pressure washer all the time, then a medium-duty washer of 2,000 to 2,800 psi would be better.

Pressure washers above 2,800psi to 3,300 psi are heavy duty and suitable for significant home improvements such as preparing a house for a paint job. Still, these washers would be unnecessary for most people. Less experienced users should opt for light to medium pressure washers.


The hose length on Karcher Pressure Washers ranges from 20 – 25 feet, giving a reasonable range for cleaning, making the job more accessible, so you don’t have to keep carrying or wheeling the washer around. The electric power cord length on the Karcher is 5 meters, but an extension cord will give an even greater range.

Karcher pressure washers offer so many multi-functional uses due to the full range of accessories. All pressure washers come with a different range of accessories, and some packages have various attachments. 

Consider what jobs you intend to do, and this will determine the specification you want. For example, to bring your patio up like new, a medium-duty pressure washer with at least 2,000psi and a patio cleaning attachment would be ideal. In contrast, if you want a washer to clean your car, then you wouldn’t need a high-pressure washer to choose one at the lower end of the range.


All Karcher pressure washers come with a warranty of either 2 or 3 years.


When using any pressure washer, there are safety precautions to adhere to.

DO read the manufacturer’s manual, wear long pants, suitable footwear, no open-toe sandals, and goggles, have the nozzle 2 feet away from the surface to start with, then get closer as required.

DON’T wash your car with a high-powered pressure washer; it could damage the paintwork. On a gas pressure washer to prevent the pump from overheating, don’t let the engine run for long without pressing the trigger, don’t use the washer while standing on a ladder, don’t point the nozzle towards other people, pets, or yourself.
