What action helps distribute pre-spray and loosen soil in carpet cleaning?

Agitation is a crucial step in the carpet cleaning process as it helps to effectively distribute the pre-spray cleaning solution throughout the carpet fibers. By agitating the carpet, whether through manual scrubbing or using mechanical equipment like a brush or a pad, the cleaning solution can penetrate deeper into the carpet material, aiding in the loosening of soil, dirt, and stains. This process not only ensures even coverage of the cleaning agent but also enhances the ability of the solution to break down and emulsify the soils, making them easier to remove during the extraction phase.

While vacuuming is important for removing loose dirt before and after cleaning, it does not help in distributing the pre-spray. Extraction is primarily for removing the dirt and cleaning solution after they have been loosened, and drying is the final step in the cleaning process that occurs after extraction is completed. Agitation, therefore, plays an essential role in setting the stage for effective soil removal by ensuring that the cleaning solution is thoroughly mixed with the contaminants in the carpet.
