Kärcher High-pressure Cleaner HD 6/15-4 M Classic | Powerful and Versatile Washer

The HD 6/15-4 M Classic high-pressure cleaner from the Classic range is a robust, versatile solution featuring a steel frame, a 4-pole low-speed motor, and a durable crankshaft pump with a brass cylinder head—ensuring long service life and minimal maintenance. Suitable for a wide range of tasks (including cleaning vehicles, production facilities, agricultural equipment, facades, and municipal projects), this mid-range machine excels in adaptability.

Its crankshaft pump handles water temperatures up to 60 °C and allows adjustment of water volume and working pressure. The 4-pole low-speed motor’s reduced speed reduces pump wear, while an integrated water filter adds protection. Key components are easily accessible for simplified maintenance, and clever accessory storage with EASY!Lock connections enables fast, intuitive accessory changes—completing its thoughtful design.

4-pole low-speed electric motor

Reduced motor speed for less pump wear. Long engine life. Only very low engine vibrations.

Robust crankshaft pump with brass cylinder head

Long service life and low maintenance costs. Pressure and water volume can be adjusted on the pump itself. With suction feature and up to 60 °C water temperature.

Simple maintenance

All important components are accessible in a few easy steps. The filling level and quality of the oil are easy to read thanks to the inspection glass. Integrated water filter can be removed and cleaned without any tools.

Features:

Kärcher’s new crankshaft pump, innovative flow channel design, with volumetric efficiency up to 93%

HD 6/15 – 4 M Classic adopts Kärcher’s advanced flow channel design, and the volumetric efficiency can reach 93%. It can output a rated flow of 600L/h and a strong pressure of 150Bar. The allowable pressure of the pump body is as high as 190Bar.

Brass pump body, all – ceramic plungers, passed 1500 – hour life test

The brass pump body is matched with 3 all – ceramic plungers, and the assembly process is strict. The whole machine (including the crankshaft pump) in Kärcher’s laboratory has passed the 1500 – hour life test.

Four – pole low – speed high – torque motor, quiet with 75.3 decibels

Upgraded with a 4 – pole copper coil low – speed motor, using 50W470 silicon steel sheets, the starting torque is increased by about 40%. With strong power and low noise, the operating volume of the whole machine is as low as 75.3 decibels.

Multiple safety protections, 4 – dimensional quality upgrade

Multiple safety protections: overcurrent protection, motor overheat protection, whole – machine waterproof protection.Four – dimensional quality upgrade: 180 – mesh precision filter, PP – T20 fixed machine shell, SPCC impact – resistant front bumper, copper coil motor.

Upgraded ergonomic push rod and 250mm soft rubber large casters, balancing mobility and shock absorption performance

The upgraded ergonomic push rod saves at least 30% effort when the machine head flips. Matched with 250mm casters, it can cross steps and obstacles, making outdoor mobile cleaning efficient and labor – saving.

Structural design of accessory hooks and storage boxes, enabling efficient and quick access and storage of accessories
