Regularity might depend on your own individual circumstances, but a good rule of thumb is to have your carpet professionally cleaned every six months or, in low traffic areas, every year. Think of it this way: unchecked, dirt and soil do a lot to shorten the life of your floors, carpet, and furniture. Dirt may seem harmless enough, but it's actually quite harsh. Left unattended, dirt grinds its way into the deepest fibers and can result in permanent damage. The good news is, committing to a regular routine of vacuuming several times a week can reduce the need for frequent cleanings and extend the life of your floors, carpets, and furniture.
