Using a Reliable Steam Cleaner, is as easy as using a vacuum cleaner. Ordinary tap water is poured into the stainless steel boiler tank and with the turn of a dial, the water in the boiler tank is pressurized and heated for approximately 7 to 12 minutes until it reaches a temperature between 302 and 320 degrees Fahrenheit. During this brief start-up time, you connect the most efficient combination of attachments from the 11-piece accessory kit to the main hose for the job at hand. Reliable steam cleaners come in a variety of sizes and provide a healthy, environmentally friendly solution when a deep clean is needed.
