The pressure of the karcher
This refers to the force at which the water is propelled. Generally, depending on the most commonly used models, the pressure varies between 150 and 250 bar. However, as is often understood, pressure is not the only criterion to consider. It is the combination of flow rate, power, and various features that is important and will affect the effectiveness of the pressure washer.
The flow of the karcher
It is expressed in liters per hour. Depending on the models of pressure washers, the flow rate varies. There are about 300 liters per hour for the most common karcher, and 600 liters per hour for the most expensive karcher.
The power of the karcher
Power represents the efficiency and speed of the karcher. It is expressed in watts. Depending on the models, the power varies between 1400 and 4000 watts.
The length of the karcher cable
As we know, water and electricity are two elements that can be very dangerous when combined. Opt for a karcher with a long power cable. Also, for safety reasons, avoid using extension cords to connect your pressure washer to an electrical outlet.
Accessories and features of the karcher
Different pressure washers are more or less sophisticated in terms of functionality and accessories. These accessories can first save time, and on the other hand, facilitate the use of your device, in other words, make it more ergonomic. Therefore, the price differs from one karcher to another. Think about the tools you would need to complement your washer and, before buying, ensure that they are compatible with the model you have chosen. Accessories are not always compatible from one brand to another.
You will find items in stores such as rotary brushes, very effective for cleaning a façade floor or terrace, special car brushes, telescopic wands, extensions or adapters for the garden hose, nozzles to adjust the spray pressure, detergents for disinfecting, sandblasting kits for stripping doors, and other innovative features allowing you to use your pressure washer optimally.
The frequency of use of the karcher
Ask yourself how you want to use your pressure washer. Indeed, the pressure of a karcher influences its performance.
For occasional use, prefer a pressure of 100 to 120 bar, so you can wash your car, terrace, or garden furniture. This type of cleaner is particularly suitable for wooden surfaces that cannot withstand too much pressure, as the wood could splinter or even gouge under high pressure.
For occasional uses, a pressure of 120 to 140 bar is necessary; this type of use is intended for tasks such as washing floors and tiles, gutters, and façades. Find our 130 bar pressure washer K 1050 TS here.
For frequent use, a pressure of over 140 bar is adequate, allowing you to clean walls, metal grates, engines, and suitable for all types of surfaces. This cleaner is particularly suitable for professional applications.
