The answer to 'why is my floor filthy' is that there are several common causes, including heavy foot traffic, lack of regular cleaning, and tracked-in dirt and debris. Symptoms may include a dull, discolored appearance, grime buildup, and a generally unkempt look.
To address a filthy floor, start by identifying the root cause. Heavy traffic areas may require more frequent sweeping and mopping. Neglected floors may need a thorough deep clean using the appropriate cleaning products and techniques. If the issue persists or you're unsure of the best approach, it's often best to call in a professional cleaning service to evaluate the situation and provide a solution.
