What are the functions of a steam cleaner?

Hello everyone, many of my friends recommend me to buy a steam cleaner. Who can tell you what functions the steam cleaner has?

Hello, the main task of this device is the cleaning of dirty surfaces with hot steam. The steam cleaner is also used for steaming in an upright position of things. It can be textiles or clothing. There is even a special Industrial steam cleaner for this. I have a certain day when I do general cleaning and the steam cleaner helps me with this.
