The eco!Booster (ecoBooster) impresses with an increased jet width for higher efficiency, reducing energy use and water consumption. Its area performance is 50% higher than the Kärcher power nozzle. Light to moderate dirt can be removed reliably and quickly. In contrast to a rotary nozzle, which is suitable for removing stubborn, adhesive dirt, with its wide water stream the eco!Booster permits deep yet gentle dirt removal even from sensitive surfaces like façades, walls, paths and vehicles.
