The SG 4/4 is a compact and robust steam cleaner which offers outstanding power and certified disinfection*. Optimal cleaning effect is achieved thanks to 4-bar steam pressure. Continuously variable steam volume control and the VapoHydro function (continuous regulation of steam saturation) mean that the machine can be adapted perfectly to any cleaning task. The 2-tank system can be refilled at any time, and ensures a rapid heat-up time as well as uninterrupted operation. The temperature indicator also helps to ensure optimal cleaning results. The machine is extremely versatile and cleans without the use of chemicals. The extensive equipment package includes two floor nozzles (for abrasive and hygienic cleaning), an integrated storage compartment for accessories, an integrated cord hook and a pipe intake for space-saving storage. (*According to prEN 16615, PVC floor, machine: SG 4/4 (floor nozzle with slats, 30 cm/sec, max. steam pressure, min. VapoHydro), test bacteria: Enterococcus hirae ATCC 10541)

Features and benefits
Steam cleaner SG 4/4: 2-tank system

2-tank system

The fresh water tank can be continually refilled, since the boiler and tank are separate. Since only part of the overall volume is heated at any one time, it takes very little time for a consistent steam pattern to form. With a total volume of over 4 litres, the SG 4/4 can be used for long periods without refilling.

Steam cleaner SG 4/4: VapoHydro


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 initially.

Steam cleaner SG 4/4: Accessory storage compartment

Accessory storage compartment

The integrated storage compartment enables the storage of a variety of accessories. Small detailed accessories are always safely stored and do not get lost. Even the suction tubes can be stored on the rear of the machine.

Hygienic cleaning
  • Hygienic cleaning without the use of chemical substances.
  • The avoidance of aggressive cleaning agents protects the operator and the surfaces treated.
  • Only water is used for cleaning – easy on both the user’s health and budget.
