Dirt embedded in your carpets is like thousands of little blades that saw at the base of your carpet fibers every time you take a step. To help protect your carpets, vacuum entrance areas and high-traffic areas on a more frequent basis, (twice a week) and the rest of the carpeting once per week.
When dirt scratches your carpet fibers, it also dulls the sheen of the carpet, making the high-traffic areas appear to stay dirtier than the rest of the carpet.
Set your vacuum to the right height for your carpet. If the vacuum height is set too high, the vacuum won’t have the ideal suction and you won’t pick up as much dirt as you could, and if its set too low, the vacuum’s roller brush and drive belt can damage the carpet. To set the vacuum’s ideal height, raise it to its highest setting, and then lower the height until you can start feeling the vacuum grabbing the carpet fibers.
