The Karcher HDS 8/18-4 Classic Hot Water Pressure Cleaner is a compact, heavy-duty three-phase machine designed for professional users who need reliable hot water cleaning performance in demanding commercial and industrial environments.

Delivering 2,610 PSI (180 Bar) working pressure, up to 3,408 PSI (235 Bar) maximum pressure, and a water flow of up to 13.3 litres per minute (800 L/h), the HDS 8/18-4 Classic provides an excellent balance of cleaning power, water volume and heat for everyday professional use.

With hot water temperatures up to 80°C, a proven Karcher crankshaft pump and a durable 4-pole electric motor, this machine is particularly well suited to workshops, transport businesses, agriculture, construction and general industrial cleaning.

Hot Water Cleaning for Grease and Oil

The HDS 8/18-4 Classic combines 180 Bar working pressure with up to 13.3 L/min water flow, providing strong cleaning performance for machinery, vehicles, equipment and hard surfaces.

Hot water up to 80°C provides a significant advantage when removing grease, oil, lubricants and other stubborn contamination that can be difficult to shift efficiently with cold water alone.

This makes the machine an excellent choice for businesses regularly cleaning:

• Machinery and equipment
• Workshop floors
• Engines and components
• Commercial vehicles
• Agricultural equipment
• Construction machinery
• Greasy or oily surfaces
• General industrial contamination

The combination of heat, pressure and water flow can also reduce reliance on detergents for many cleaning applications.

Heavy-Duty Three-Phase Electric Power

The HDS 8/18-4 Classic operates from a 400 V three-phase electrical supply and is powered by a robust 5.5 kW, 4-pole electric motor.

The 4-pole motor configuration is designed for professional use and provides smooth, dependable operation under regular commercial workloads.

This makes the machine particularly suitable for workshops, depots, factories and other facilities where three-phase power is available.

Proven Karcher Crankshaft Pump

At the heart of the HDS 8/18-4 Classic is a durable crankshaft high-pressure pump designed for professional cleaning applications.

The crankshaft design provides dependable performance and long service life, while the integrated water filter helps protect internal components from contamination entering through the water supply.

For businesses that value straightforward, robust equipment, the Classic platform provides excellent durability without unnecessary complexity.

Compact Classic Design

The HDS 8/18-4 Classic is designed to provide professional hot water performance in a more compact package than larger industrial HDS machines.

Its tubular steel protective frame shields major components from impact while providing easy service access.

Large puncture-proof wheels improve mobility across workshops, yards and uneven surfaces, while the integrated crane lifting point allows safe loading and repositioning when required.

An onboard accessory storage compartment helps keep equipment organised during transport and everyday use.

Eco!efficiency Mode

Karcher's eco!efficiency mode allows economical hot water operation at approximately 60°C.

This optimised temperature range helps reduce burner fuel consumption and emissions while still providing effective hot water cleaning performance for many everyday applications.

For businesses using the machine frequently, lower fuel consumption can help reduce ongoing operating costs.
