A carpet shampooer is a cleaning machine designed to remove dirt, stains, and odors from carpets and rugs. It works by applying a mixture of water and cleaning solution to the carpet fibers, agitating them to loosen dirt, and then extracting the dirty water back into the machine. This process helps to refresh and maintain the appearance of carpets. Carpet shampooers come in various types, including upright models and portable units. Some are designed for home use, while others are more powerful and suitable for commercial applications. Regular use of a carpet shampooer can extend the life of carpets and improve indoor air quality.
