4.3 High-Temperature Steam and Suction

• 170°C Steam: The cleaner produces high-temperature steam (boiler temperature 170°C) with a steam volume of 25-35g/min and a vapor pressure of 2.5 bar. This powerful steam effectively dissolves stubborn oil stains and provides deep sterilization, killing over 99.99% of bacteria like Escherichia coli and Staphylococcus aureus, and achieving 100% mite removal.
• 15000Pa Suction: The strong suction power ensures that dirt and moisture are quickly absorbed from fabrics, accelerating drying and preventing residue buildup.
