Under high pressure: outdoor cleaning when water is scarce

In hot months, scarcity of water is an important issue. How much water can I use around the house and garden and for what? The most important facts about the water consumption of pressure washers and the cleverest techniques for resource-saving cleaning tasks in the outside area are summarised here at a glance.

The good news is that any required cleaning tasks, for example on the patio, pavement or garden furniture, don't necessarily have to wait – especially if safety or durability (for example, due to the risk of slipping or wear and tear) is at stake. With its range of pressure washers, Kärcher offers water-saving and energy-saving cleaning solutions that help keep personal water consumption under control – and not just in the event of a water 'red alert'.

Did you know?

Global water demand has more than doubled since 1960. This rapidly increasing demand is leading to water shortages. In Europe, this is being counteracted primarily using a local water 'traffic light system' and through restrictions on watering green spaces or filling pools.

What makes this saving possible?

Thanks to the patented nozzle technology of the Kärcher Dirt Blasters and sophisticated pump and motor technology of the Kärcher pressure washers, low water consumption is ensured. This makes all cleaning faster, and saves time, water and energy in equal measure.

Incidentally, pressure washers from Kärcher are particularly efficient at cleaning. This is the result of an independent laboratory test. Compared with competitor products, the Kärcher devices offered the widest and thus the most efficient cleaning jet*.

* Result of a laboratory test conducted in April 2023 by the independent SLG Prüf- und Zertifizierungs GmbH. Rotary nozzles of pressure washers with similar or higher specifications for the maximum water pressure were compared.

An efficient accessory saves water, time and energy

With the eco!Booster spray lance, the water and energy efficiency is 50% higher than it is for application with a standard Kärcher flat jet.* This means that surfaces get clean faster with the same use of resources. * Based on the fact that 50% more surface area can be cleaned with the same amount of energy and water compared with the standard Kärcher flat jet. Confirmed by an independent testing institute.
