Which equipment is essential in the hot water extraction method?

In the hot water extraction method, the extraction machine is essential because it is specifically designed to perform the key functions of this cleaning technique. This equipment heats water to a high temperature and uses it to deeply penetrate the carpet fibers, loosening dirt, debris, and stains. After the hot water is applied, the extraction machine efficiently removes the dirty water and dislodged contaminants from the carpet.

The effectiveness of the hot water extraction process relies heavily on the capability of the extraction machine to thoroughly suction up the water and soil mixture, ensuring that the carpet dries properly and reducing the potential for mold growth or odor retention. Other equipment, while useful in different contexts of carpet maintenance or preparation, does not fulfill the core requirement of extracting the solution from the carpet after cleaning.
