Carpet cleaners are machines designed to remove dirt, stains, and allergens from carpets and rugs. They typically use a combination of water, cleaning solutions, and suction to deep clean the fibers of the carpet. Some common types include steam cleaners, dry cleaners, and shampooers, each with its own method of cleaning. These devices can be used in homes, offices, and commercial spaces to maintain cleanliness and improve indoor air quality. Regular use of carpet cleaners can extend the life of carpets and enhance their appearance, making them an essential tool for home maintenance.
