The answer to 'floor odor' is that there are several common causes, including spills, pet accidents, mold, and poor ventilation. Symptoms include a persistent, unpleasant smell that won't go away with basic cleaning. The best solution depends on the root cause, but may involve deep cleaning, odor removal treatments, or professional help in some cases.
If the odor is mild and you can identify the source, such as a recent spill, you may be able to handle it with DIY cleaning methods. However, if the odor is strong, persistent, or you suspect mold or other underlying issues, it's best to call in a professional cleaning service to properly diagnose and address the problem.
