About this product
The Karcher K 5 WCM Flex eco!Booster is a 145 bar pressure washer suited to frequent use on moderate to heavy dirt around the home and garden, cleaning paths, patios, driveways, garden furniture and vehicles. It has a water-cooled motor for reliable, extended operation.
The supplied eco!Booster lance gives 50% more cleaning performance than a standard flat jet, suiting delicate surfaces while using water and energy efficiently, while the dirt blaster spray lance handles stubborn grime. A 10m PremiumFlex high-pressure hose gives good reach and flexibility, and a built-in water filter protects the pump.
Accessories fit via a Quick Connect System and store onboard the unit. Detergent can be applied through the suction hose, and the Karcher app offers setup and application guidance. Max flow rate is 500 l/hr, max water feed temperature 40°C, and the machine weighs 12.6kg.
