DESCRIPTION

The Karcher HD 3.0/20-4 M Cage high-pressure cleaner combines durability and efficiency for tough commercial tasks. It features the EASY!Force high-pressure gun, which eliminates holding force using jet recoil, and EASY!Lock quick-release couplings for 5x faster setup. A powder-coated tubular steel frame ensures protection during heavy use, while automatic pressure relief safeguards internal components. Powered by a 4-pole, slow-running AC motor and a 3-piston axial pump with brass cylinder head, it delivers 20% improved cleaning performance and energy efficiency. Suitable for vertical or horizontal use and designed for easy maintenance access.

KEY APPLICATIONS:

• Industrial Facility Cleaning – Efficiently removes tough dirt and grime from factory floors, machinery, and equipment.

• Construction Site Maintenance – Ideal for cleaning construction tools, heavy machinery, and vehicles exposed to mud and debris.

• Vehicle Fleet Washing – Suitable for high-frequency cleaning of trucks, vans, and service vehicles in transport and logistics.

• Agriculture Equipment Cleaning – Maintains hygiene and performance of farming machinery and barns.

• Municipal and Public Area Cleaning – Perfect for cleaning pavements, street furniture, public restrooms, and service areas.

• Heavy-Duty Workshop Use – Durable and powerful enough for routine cleaning in repair shops and maintenance depots.
