Karcher Pressure Washer K4

The Kärcher K4 pressure washer is a powerful and mobile pressure washer ideal for all cleaning tasks around the home. The K4 comes with a Vario Power Lance, universal detergent and water-cooled motor.  The Kärcher K4 Pressure Washer combines power with an innovative water-cooled induction motor for enhanced performance and longer life.  Matching its power and design, the Quick Connect hose system efficiently eliminates kinking and reduces set up times, making it a convenient solution for cleaning your home. The Karcher K4 includes a Vario Lance, detergent suction hose and Dirtblaster Lance which provides up to 50% greater cleaning power than a standard high pressure lance. The Karcher pressure washer’s plug & clean detergent system makes it simple to use and easy to switch between a low pressure detergent application and a high pressure wash jet. With an upright design, wheels and a long handle, the Kärcher K4 ensures excellent mobility.  An impact-resistant casing and fine mesh water filter prevent dirt particles from damaging the motor and three-piston axial-flow pump, whilst a safety valve prevents pressure overload.  All Kärcher K4 pressure washers can work using a static or harvested water source drawn using a Kärcher suction hose and filter, or connected to a water butt tap.  The K4 Karcher Pressure Washer comes with a 3 year guarantee as standard.
