You couldn't get a better performance from Kärcher's top range of hot water high-pressure cleaners - the HDS 13 / 20-4 S is the most powerful equipment we can offer. The high water flow allows a service with two lances that facilitates and accelerates the most laborious jobs. The EASY! Force high pressure gun takes advantage of the recoil force of the high pressure jet, thus neutralizing the holding force on the trigger. The equipment is characterized by a wide range of innovative specific equipment, such as the eco! Efficiency mode, the service switch for regulating the water hardness, the turbofan, a precise dosage of the detergent, the optimized burner technology and the high pump efficiency, not forgetting the patented nozzle technology, very effective and with powerful cleaning results. A second highlight is the large LED display that allows you to easily consult the fuel, detergent fill levels and indications for the maintenance of the system at all times. The easy handling, the successful mobility concept and the easy access to all relevant components make handling, transport and service work easy for the user.
