Karcher SG 4/4 Professional Steam Cleaner

Kärcher SG 4/4 Professional Steam Cleaner

High-Performance 4-Bar Steam Cleaning for Hygienic Results

The Kärcher SG 4/4 is a compact, powerful professional steam cleaner designed for fast, deep and hygienic cleaning without chemicals. With its strong 4-bar steam output and a large 4-litre total tank capacity, it is ideal for commercial environments that require reliable, continuous sanitation, including kitchens, washrooms, healthcare settings and hospitality facilities.

Two-Tank System for Continuous Operation

The SG 4/4 features a two-tank system that allows the fresh water tank to be refilled at any time. Because the boiler and tank are separate, only part of the total volume is heated, providing short heat-up times and uninterrupted cleaning sessions.

VapoHydro for Stubborn Dirt

The VapoHydro function enables continuous adjustment of steam saturation, from full steam through to a powerful hot water jet. This added flexibility makes it easy to dissolve grease, limescale and stubborn residues quickly and effectively.

Efficient, Chemical-Free Cleaning

Using only water, the SG 4/4 provides hygienic cleaning that protects both users and treated surfaces. It eliminates the need for aggressive detergents, reducing costs and supporting safer working practices.

Extensive Accessory Package Included

The machine includes floor nozzles, detail nozzles, steam pipes, brushes and cloths, along with integrated storage for tools, cords and suction tubes. This ensures the SG 4/4 is ready for a wide range of deep cleaning and sanitation tasks.
