The Kärcher K 3 eco!Booster offers reliable, versatile cleaning for small outdoor areas. Featuring both the eco!Booster lance for gentle, efficient cleaning and the Dirt Blaster for stubborn grime, it provides powerful yet economical performance for occasional home use.
The Kärcher K 3 eco!Booster is built to make everyday outdoor cleaning simple, efficient and effective. Designed for occasional use around the home, it ensures small to medium outdoor areas—such as patios, outdoor furniture, bicycles and garden tools—can be restored quickly and easily. A long‑lasting pump protected by an integrated water filter provides dependable performance, while the 6‑metre high‑pressure hose gives excellent reach without constant repositioning.
This model delivers exceptional versatility thanks to two included lances. The eco!Booster lance provides up to 50% increased cleaning performance compared with the Kärcher flat jet, making it ideal for delicate surfaces while improving both water and energy efficiency. For more demanding tasks, the Dirt Blaster lance provides a concentrated rotating jet capable of tackling tough, ingrained dirt with ease.
Convenience is built in with the Quick Connect system, smooth‑rolling wheels and onboard storage. For added guidance, the Kärcher Home & Garden app offers task‑specific cleaning tips, setup help and step‑by‑step advice to get the best performance from every clean.
