Shampooing your carpet is a critical step in the home cleaning process. Your carpets may look soft and cozy but, they can harbor dirt, hair, dust, food crumbs, and other debris. While vacuuming removes a lot of the loose dirt and grime, shampooing removes any dirt caked onto carpet fibers. This caked-on dirt can make your carpets look discolored and dingy even if you vacuum regularly. Additionally, dirty carpets can often smell which means your home will smell too. And any home with pets or kids knows that accidents and spills happen.
