Pressurized Hot Water Extraction aka "Steam Cleaning"
Steam Cleaning uses hot water to clean the carpet. Hot water is sprayed on the fibers. Water temperature usually reaches up to 240 degree Fahrenheit. The cleaning equipment sprays pressurized hot water, allowing the hot water to reach deep in to carpet fibers and disolve the dirt right on contact. Powefull vacuum then immediately extracts dirty water from the carpet right after the water is sprayed. Steam cleaning is a very effective carpet cleaning method, recumended by IICRC amd most carpet manufactuers.
