The Kärcher K 7 WCM Flex eco!Booster is a powerful, water‑cooled pressure washer designed for frequent cleaning and heavy dirt. Equipped with the eco!Booster lance for a 50% increase in cleaning performance*, it provides efficient, effective cleaning across patios, pathways, garden tools and larger vehicles.
Engineered for demanding outdoor cleaning tasks, the Kärcher K 7 WCM Flex eco!Booster combines a robust water‑cooled motor with advanced technology to deliver exceptional performance. It is designed to tackle everything from stubborn dirt on stone surfaces to large vehicles, making it the perfect companion for regular, high‑intensity cleaning around the home.
The included eco!Booster lance enhances cleaning performance by up to 50% compared to the standard Kärcher flat jet, allowing faster results while improving water and energy efficiency. For particularly tough grime, the dirtblaster lance provides an extra boost of power to achieve deep, uncompromising cleaning.
