Steam Cleaning vs Carpet Shampooing: What's the Difference?
Two carpet-cleaning methods that get mixed up — and why the difference matters.
People often use "steam cleaning" and "carpet shampooing" to mean the same thing, but they're different methods with different results. Knowing the difference helps you ask the right questions when you get a quote.
What "steam cleaning" really means
Despite the name, steam cleaning doesn't use dry steam. It's hot water extraction: hot water and a cleaning solution are sprayed into the carpet, and strong suction pulls the water back out along with the dirt it has loosened.
It's a rinse-and-extract process, which is why it reaches the dirt that has settled into the pile instead of just the surface.
What carpet shampooing is
Traditional shampooing works the other way round: a foaming detergent is applied and worked into the carpet, and the carpet is left to dry before the residue is vacuumed up.
Because it doesn't rinse the carpet out, it can leave some residue behind, and that residue can attract dirt and make carpet look dirty again sooner. Results vary with the equipment, the products and how it's done.
Which should you choose?
For a deep clean of most carpets, hot water extraction is the method we use, and it's the one we'd usually recommend. Some delicate fibres and carpets need a gentler approach, so it always starts with checking what you have.
If you're comparing quotes, ask each cleaner what method they use, and how they deal with stains and drying.
