Nothing cleans more thoroughly, or protects your investment better than hot water extraction. It is the preferred carpet cleaning method recommended by most carpet manufacturers, including Shaw Industries and Mohawk Carpets, the largest manufacturers of carpet in the world.
Though commonly called “Steam Cleaning”, no actual steam is involved in the hot water extraction cleaning process. When the cleaning solution comes in contact with the carpet/rug, it is anywhere between 120-250 degrees Fahrenheit.
This is the only cleaning method classified as “deep cleaning”. All the others are considered “light surface cleaning” because they are incapable of removing soil deep in the pile. Also, all other methods leave large amounts of cleaning agent in the carpet after cleaning.
The maintenance brochure published by the world’s largest carpet manufacturer, Shaw Industries, recommends this method, because its own research indicates that it provides the best capability for cleaning.
This method is frequently called “steam” cleaning due to the fine spray of water used to force dirt out of the carpet which is sucked up by the vacuum slot immediately in front of the spray. Seldom is real live steam used, however. This process consists of spraying a solution of water and detergent into the carpet pile and recovering the water and soil with a powerful vacuum into a holding tank. This can be done from a truck-mounted unit outside the home with only the hose and floor tool brought inside, or by a portable, system brought into the home or office.
From a health standpoint, the truck-mounted system is preferred because the dirty air and humidity are exhausted outside rather than recirculated around the house. Additionally, truck-mounted systems usually are more powerful than portable units and do a much better cleaning job and get the carpet dry more quickly.
