High-pressure cleaner Kärcher K 4 WCM Premium Home

The High-pressure cleaner Kärcher K 4 WCM Premium Home is a mid-range electric pressure washer designed for regular domestic cleaning tasks. It combines a compact, lightweight body with a powerful motor and adjustable pressure settings to handle a variety of outdoor cleaning jobs. Integrated accessories include a dirt blaster lance for stubborn grime, a built-in hose reel for neat storage, and a surface cleaner for flat areas such as patios and driveways. The ergonomic handle and wheels provide easy maneuverability around the garden and home exterior.

Advantages

The unit delivers adjustable cleaning power that adapts to surfaces from delicate garden furniture to hard pavement, reducing the risk of surface damage while improving cleaning efficiency. The dirt blaster attachment concentrates water flow for effective removal of stubborn dirt and stains. Built-in hose storage and a compact design minimize setup and storage space. The supplied surface cleaner ensures even cleaning of horizontal surfaces with reduced splash-back and faster coverage compared to a standard lance.

Key specifications

• Power source: electric motor for domestic mains connection

How to use

Connect the cleaner to a suitable water supply and household power outlet following the safety instructions in the manufacturer manual. Attach the required accessory—use the dirt blaster for concentrated heavy-duty cleaning or the surface cleaner for horizontal areas. Set the pressure to a level appropriate for the surface: lower pressure for painted or delicate surfaces, higher pressure for stone and concrete. Move the lance or surface cleaner steadily across the area, maintaining a safe distance from sensitive materials. After use, switch off the unit, release residual pressure, and wind the high-pressure hose onto the integrated reel for storage.

Usage recommendations

For best results, inspect surfaces for loose paint or fragile elements before cleaning, test pressure on a small hidden area, and wear appropriate eye and hand protection. Use detaching attachments only when the unit is switched off and pressure has been released. Store the appliance and accessories in a frost-free environment to prevent damage to seals and internal components.
