How does steam cleaning work on your carpets?
Carpets are excellent filters for trapping contaminants that would otherwise be in the air you breathe. Most vacuums are not powerful enough and lack good filtration to remove all of the pollutants in your carpet and home. Furthermore, vacuums do not use a cleaning solution, and many soiled spots need to be emulsified to be removed. Not removing soiled spots and contaminants will shorten the life of your carpet.
Steam cleaning (officially known as hot water extraction) injects heated water vapor and cleaning solutions deep into the carpet fibers to dissolve grime, then immediately vacuums up the moisture and loosened debris. It sanitizes, removes stubborn spots, and extracts allergens that regular vacuuming cannot reach.
