Features and Benefits

Two-tank system

The fresh water tank can be continuously filled as the boiler and tank are separate. Since only part of the overall volume is heated, a constant steam flow is quickly produced. With a total capacity of over 4 litres, the SG 4/4 can be used for long periods without refilling.


Thanks to VapoHydro, the steam level can be infinitely adjusted to the cleaning task. In addition to the steam pressure, the saturation can be infinitely adjusted from full steam to hot water. With the hot water jet, even stubborn dirt can be effectively dissolved from the start.

Accessory storage compartment

The on-board storage compartment enables storage of a variety of accessories. Special small parts are always safely stored and cannot get lost. Tubes can also be stored at the rear of the unit.


Hygienic cleaning
  1. Hygienic cleaning without the use of chemical substances.
  2. The avoidance of aggressive cleaning agents protects the operator and treated surfaces.
  3. Only water is used for cleaning – unharmful to health and cost-effective.
