The patented Kärcher nozzle technology suited to each individual model make it possible to save up to 50% cleaning time. Compared with the competition, the Kärcher devices are distinguished by a greater cleaning performance and efficiency. In short: cleaning takes place faster with time savings of up to 50% and thus also energy and water savings of up to 50% – remarkable advantages which have been scientifically confirmed by the renowned and independent Fraunhofer Institute.
