Carpets can get dirty easily, particularly if you always bring your shoes inside. Dirt, sand and other outdoor pollutants will transfer onto your carpets and stay there until the next cleaning. However, if these small debris are not removed, harmful bacteria will likely grow and thrive underneath your floor coverings. Once that happens, you and everyone in your household will be in danger of catching an illness. In addition, tiny particles that are ignored can cause damage to your floor coverings as they are abrasive and will rub against your carpets’ fibers, leading to unnecessary repairs or replacement.
