The answer to 'carpet neglected' is that carpets that are not properly maintained can develop a variety of issues, including discoloration, matting, and odors. Neglected carpets are often the result of infrequent vacuuming, lack of deep cleaning, and spills or stains that are left untreated.
Some common symptoms of neglected carpets include visible dirt and debris, noticeable stains or discoloration, and a musty or unpleasant odor. In severe cases, neglected carpets may also harbor dust mites, bacteria, and other allergens that can negatively impact indoor air quality.
