When selecting a water blaster, it's important to not only look at PSI when making your decision. There are many factors which impact a water blaster's performance. For example, the nozzle technology impacts the width of the surface area being cleaned at once. Kärcher has patented nozzle technology in all of our water blasters which has been tested against our competition and has been found to clean more surface area at once, meaning you can do your cleaning job quicker. 

There are numerous other important factors that also impact a pressure washer's performance. Below is a list factors that helps Kärcher distinguish ourselves from the competition:

  • Patented pump technology for a long lasting water blaster.
  • Accessory range that suits ALL old or new products.

Clean up to 4 x faster than with a lance with a Kärcher T-Racer surface cleaner. The innovative combination of height-adjustable propellers and high-pressure nozzles create a hovercraft effect which allows the T-Racer to hover above the ground with gentle action and uniform results on large areas. The casing prevents splashback, thereby protecting both you and the walls from spray. The T Racer is ideal for cleaning driveaways, decks, paving, garage doors and more.

Garden equipment

Say goodbye to scrubbing! Dirt and earth can be removed efficiently from plant and flower pots, spades, shovels, rakes and wheelbarrows using a Kärcher water blaster. The Vario Power and Multi Power Jet spray lances make light work of a traditionally labour intensive task.

Mossy paving

Since moss not only forms a thick layer on paved surfaces, but remains in the pores of the paving stones, the dirt blaster is the ultimate tool to remove moss quickly and effectively. The dirst blaster is a rotating jet, which combines the cleaning power of a concentrated jet with the area performance of a flat stream. Hold the high-pressure jet vertically to the paved surface and slowly clean from one edge of the moss-covered area to the other at a distance of around 20 to 30 cm - job done!

Before cleaning close the shutters. Set the spray lance to low pressure and apply the cleaning agent. Start at the lowest section of the shutters. Leave the cleaning agent to work in for a few minutes so that the dirt is loosened completely. Remove the dissolved dirt with the wash brush and finally rinse with the high-pressure jet.

Performance Class

Which model is right for you?

The cleaning performance of a water blaster is determined by how the water pressure and water volume are used in combination. The better these two factors are aligned, the easier it is to remove stubborn dirt and the quicker large surface areas can be cleaned. Kärcher puts its devices into specific performance classes based on different cleaning requirements. The larger the surface area to be cleaned and/or the more stubborn the dirt, the higher the performance class recommended. To clean large surface areas such as façades, a K7 device with matching accessories is recommended. As well as offering better performance, higher unit classes also offer other practical functions. These include longer hose lengths for a considerably extended working radius and better hose quality to improve twist resistance and flexibility. This ensures short set-up times and considerably more comfort, especially in the case of frequent use.


How does a water blaster work?

Pressure in a normal household water supply is around 4 bar. Water supplied into the water blaster via a garden hose, passes through a booster pump which generates water pressure of up to 160 bar. The water is ejected through a small high-pressure nozzle as a concentrated jet with a high cleaning effect.

Kärcher makes the difference

Kärcher invented the high-pressure washer – and continues to reinvent it again and again. In 1950 Kärcher developed the first European hot water high-pressure washer for professional cleaning. In 1984 Kärcher then launched the first portable pressure washer, the HD 555, for private households – a milestone in the history of cleaning.

As the inventor of high-pressure cleaning, Kärcher has unique specialist knowledge, the breadth and depth of which is unrivalled on the market. We use regular surveys to conscientiously determine what our customers want and need and any findings are incorporated directly into product development. This is how we ensure that each new development meets the needs of our customers.


Kärcher continues to create market leading innovations in perfecting the art of high-pressure cleaning. More than 1,300 patents and utility models are evidence of our dedication to creating the ultimate cleaning solutions for our customers.


The rotating high-pressure jet combines the power of a narrow jet with the area performance of a flat stream. Thanks to their patented nozzle technology, Kärcher's dirt blasters outperform the competition and enable faster and more efficient cleaning thanks to maximum stripping performance.


Time saving Karcher

Exceptionally powerful – 50% time saving

The patented Kärcher nozzle technology suited to each individual model make it possible to save upto 50% cleaning time. Compared with the competition, the Kärcher devices are distinguished by a greater cleaning performance and efficiency.
