Who is most likely responsible for overwetting a carpet during cleaning?

Overwetting a carpet during cleaning is primarily the responsibility of the technician. This can occur due to a variety of factors related to the technician's technique and approach. For instance, a technician may use excessive water or cleaning solution during the process, apply too much pressure while using cleaning equipment, or fail to adequately extract moisture afterward.

In professional carpet cleaning, it’s crucial for the technician to follow proper procedures and adjust their methods according to the type of carpet and soil level to minimize moisture retention. While customers, cleaning agents, and equipment can influence the outcome, it is ultimately the technician who controls the cleaning process and the amount of moisture applied to the carpet.
