A carpet cleaner is a machine designed to remove dirt, stains, and odors from carpets and rugs. It typically uses a combination of water, cleaning solution, and suction to deep clean the fibers of the carpet. Some models are portable, while others are larger and meant for professional use. There are two main types of carpet cleaners: steam cleaners, which use hot water vapor to lift dirt, and dry cleaners, which use minimal moisture and special powders. Regular use of a carpet cleaner can help maintain the appearance and longevity of carpets, making them look fresh and clean.
