The answer to 'when to clean carpet cleaning' is that carpets should be professionally cleaned every 12-18 months, or more frequently if they see heavy foot traffic or have visible soiling. Regular cleaning helps extend the life of your carpets, removes embedded dirt and allergens, and maintains their appearance. It's best to have carpets cleaned by a professional carpet cleaning service using truck-mounted extraction equipment, which can deep clean more effectively than rental machines or DIY methods.
Carpets in high-traffic areas like entryways, hallways, and living rooms may need cleaning more often, such as every 6-12 months. Lightly used carpets in bedrooms can often go 18-24 months between professional cleanings. Pay attention to how your carpets look and feel - if they start to appear dingy or feel crunchy underfoot, it's time for a thorough cleaning.
