The Kärcher HDS 13/20-4 S is the most powerful hot water high-pressure cleaner in Kärcher’s renowned Super Class. With a working pressure of 200 Bar and a flow rate of up to 1300 L/h, it is designed for tackling the toughest industrial cleaning jobs, capable of supporting two-lance operation for maximum productivity.

Engineered for durability, this model features a water-cooled, 4-pole electric motor, a three-piston axial pump, and a stainless steel heating coil that resists corrosion and prevents black water build-up. Advanced technologies like eco!efficiency mode, precise detergent dosing, turbo blower, and optimised burner engineering deliver exceptional cleaning power while conserving resources and reducing emissions.

Operational ease is guaranteed with the EASY!Force high-pressure gun, which eliminates holding force by utilising jet recoil, and the EASY!Lock quick-release system, which is five times faster than conventional connections. The large LED display clearly shows levels for fuel, detergent, and maintenance, and service intervals are easy to monitor via the integrated control system.
