Steam cleaner: how it works

In short: A steam cleaner heats water until it vaporizes, using the hot steam to dissolve dirt, grease, and germs, often without additional chemicals. The heat of over 100 degrees Celsius also acts as a disinfectant.

In more detail: Inside the device, a heating element in a pressure boiler generates steam, which is directed at the surface to be cleaned through a hose and various attachments.

In detail

• Pressure boiler: Water is heated under pressure above 100 degrees Celsius, producing drier, hotter steam than normal boiling would.
• Dissolving action: The heat and moisture loosen dried-on dirt and grease films without needing much scrubbing.
• Hygienic effect: Temperatures above 100 degrees directly kill many bacteria, mites, and mold spores (kalkablagerungen-im-haushalt-entfernen).
• Attachments: Various nozzles and brush heads work well for grout, windows, upholstery, or smooth floors.
• Material compatibility: Heat-sensitive surfaces like untreated wood or some finishes can be damaged by the heat.
• Water quality: Distilled or softened water prevents limescale buildup in the device and extends its lifespan.
• Cooling time: Surfaces often remain slightly slippery for a short time after cleaning due to residual moisture, until they dry completely.
