Efficient, Budget-Friendly Cleaning for K2 & K3 Pressure Washers
The Karcher Eco!Booster Lance 120 (High-Efficiency Pressure Saving Lance) is a cost-effective accessory designed for users who want improved cleaning performance while reducing water and energy use. Whether you think of it as a budget eco lance, water-saving pressure lance or eco-efficient spray lance, this attachment helps deliver better results from compact Kärcher machines without increasing running costs.
Although cosmetically different from other Eco!Booster models, the Karcher Eco!Booster Lance 120 uses the same efficiency-focused principle: directing water through a specially shaped spray channel that boosts cleaning impact at lower pressures. This makes it ideal for Karcher K2 and K3 Series users who want better overall cleaning performance without upgrading their machine.
Lightweight and easy to handle, the Eco!Booster 120 Lance is well suited to smaller outdoor tasks including patios, decking, fencing, furniture, bikes, tools and garden equipment. It provides an effective balance of cleaning power and reduced resource use, making it a smart upgrade for eco-conscious homeowners.
What’s the difference between the Eco!Booster 120 and other Eco!Booster models?
The Karcher Eco!Booster Lance 120 is the budget-friendly, compact version designed specifically for Karcher K 2 and K 3 Series pressure washers. The Eco!Booster 130, 145 and 180 offer increased performance for higher-powered machines, but the Eco!Booster 120 focuses on affordability and efficiency for entry-level users. It delivers noticeable cleaning improvement while maintaining low running costs.
Why should I buy a Karcher Eco!Booster Lance 120?
