What are carpet shampoo machines used for?

Carpet shampoo machines are used to deep clean carpets by combining water, detergent, and agitation to loosen and remove dirt, stains, and other debris. They work by spraying a hot water and detergent mixture onto the carpet and then using a rotating brush to agitate and lift the dirt and stains. The dirty water and detergent are then sucked back up into the machine, leaving the carpet clean. Carpet shampoo machines are commonly used in homes, offices, and other commercial spaces.
