Karcher HDS 7/12-4 M EASY! – 240V 3.4KW 1740PSI Hot Water High Pressure Cleaner

The Karcher HDS 7/12-4 M EASY! – 240V 3.4KW 1740PSI Hot Water High Pressure Cleaner is a large and heavy item.


  • Economical – In the Eco mode, the unit operates in the most economical temperature range (60°C) with full water flow. Burner cycles are optimised to reduce fuel consumption by up to 20% compared to full-load operation. The stainless steel heating coil offers lasting protection against corrosion and prevents the formation of black water.  HDS 7/12-4 M EASY!: Operational reliability
  • Operational reliability – The large, integrated fine-mesh water filter reliably protects the high-pressure pump against the ingress of dirt particles. An integrated exhaust gas thermostat switches off the drive motor if the exhaust gas temperature exceeds 300°C. The soft damping system (SDS) compensates for vibrations and pressure surges in the high-pressure system.  HDS 7/12-4 M EASY!: Storage
  • Storage – Storage hooks for power cord and high-pressure hose.
