The most important thing you can do to keep your carpet looking great is to vacuum it. Do this thoroughly and regularly, especially in high traffic areas. For best results, use a vacuum with a beater bar or rotating brush and plenty of suction. Change bags and filters routinely, and keep recovery tanks clean. Studies show that even a well maintained vacuum can lose 80% of its "pick up ability" when the bag reaches 25% full.
Set adjustments according to recommendations for your type of carpet. Heavy traffic areas like entryways should be vacuumed regularly, daily if possible. Walk off mats at entrances can dramatically reduce tracked in dirt. Less heavily used areas can be vacuumed less often, perhaps weekly. Vacuum three passes for light cleaning and up to seven passes where there's been heavy soiling or traffic.
Why is vacuuming so important? That's because most of the "dirt" found in our carpets is tracked in by us and our pets. This insoluble "dry practice soil", consisting of mostly sand, clay, and quartz, is easily removed through regular vacuuming. If this dry soil is left to build up underfoot, the grit constantly rubs against your carpet fibers like sandpaper.
