Carpet Shampooing: How Often to Deep Clean Your Carpet

What It Means

Carpet shampooing is the everyday name for deep cleaning a carpet with a cleaning solution and a machine that works it into the pile and pulls the dirty water back out. The Carpet and Rug Institute (CRI) calls this deep cleaning and names hot water extraction as the method that removes the most soil and leaves the least residue when done to the professional standard. It comes on top of regular vacuuming, which handles the loose dirt in between.

Doing it yourself or hiring it out. CRI's Seal of Approval program covers deep cleaning extractors and cleaning systems, and it also certifies professional cleaning companies. Some carpet makers recommend or require a certified cleaner for the warranty to hold, so read yours before you choose.

Make it last between deep cleans

Vacuum every week so grit doesn't wear the fibers down.
Treat spills when they happen, using a product and method your carpet maker allows.
Put the dates of the last and next deep clean somewhere the household can see them.

Good to Know

Keep the paperwork. CRI notes that most carpet warranties require extraction cleaning at a set interval, usually every 12 to 18 months, so a missed deep clean can matter when you make a claim. Look for CRI's Seal of Approval on the machine or the cleaning company, and follow the cleaning solution's label on dilution and ventilation.

People use carpet shampooing loosely for any machine deep clean. CRI names hot water extraction, done to the professional cleaning standard, as the method that pulls out the most soil and leaves the least residue.

Does carpet cleaning affect my warranty?

It can. CRI says most carpet warranties require extraction cleaning within a set time, usually every 12 to 18 months, and some makers require a certified cleaner.
