Regular vacuuming (Weekly in low-traffic areas, and daily or twice daily in areas with higher traffic) with a motor-driven brush and beater bar can remove up to 80% of surface dirt, and is the easiest way to prolong the life of your carpet. Regular vacuuming is key to maintaining your carpet, but eventually the carpet color dulls from dirt and grime stuck in the fibers. The dirt is then carried further into the building to form more soil reservoirs. Additionally, the oil content (15%) of the soil causes particles to stick to carpet fiber and resist vacuuming. To restore the carpet to its best condition, frequent light cleaning gives the best result and is often very cost effective
