Do professional carpet cleaners use steam?

Many professional carpet cleaners use steam cleaning, also known as hot water extraction, as it is an effective method for cleaning carpets. Steam cleaning uses hot water and a cleaning solution to clean the carpet. The solution is injected into the carpet using a powerful machine, and then extracted using a vacuum. The high temperature of the water and the pressure of the vacuum work together to remove dirt, stains, and other debris that is embedded in the carpet fibers. It's considered a deep cleaning method and can effectively remove allergens, bacteria, and other microorganisms.
Professional carpet cleaners have the necessary equipment, cleaning solutions and experience to perform the task effectively, and in most cases, they will have a truck-mounted unit which is more powerful than portable units that can be rented or bought by homeowners.
It's important to note that not all professional carpet cleaners use steam cleaning, some may use other methods such as shampooing or dry cleaning. It's important to ask the cleaner which method they use and to ensure that they are using the appropriate method for your carpet type.
