Steam Cleaning Carpets vs. Shampooing: Which is Better?
Freshen up the carpet with these two trusted methods
Highlights
Both carpet steaming and shampooing are popular deep-clean options.
Steam cleaning pushes and pulls highly-pressurized hot water through carpet fibers.
Carpet shampooing includes a detergent and agitating brushes to loosen dirt.
Both methods are DIY-friendly, but more successful when you hire a professional.
After a few months of mucky shoes, spills, and a few layers of pet hair, your carpets are not looking their best. You have your pick of carpet cleaning methods, the most popular of which are steam cleaning or shampooing. And while similar in many ways, they tackle carpet stains differently. Let's look at them side by side.
Carpet Steam Cleaning vs. Shampooing: Key Differences
When comparing carpet steam cleaning vs. shampooing, both methods deep clean carpets of nearly all varieties, including tricky fibers like wool. Steam cleaning uses a high-power flow of hot water to loosen dirt off the fibers and then pull the moisture back into the machine. Carpet shampooing uses a combination of warm water and chemical shampoo to break down dirt, and rolling bristles to dig deeper into the rug. While both provide a deep clean, they're not ideal in all situations.
| Steam Cleaning | Shampooing |
|---|---|
| Hot water only | Warm water and shampoo |
| Various nozzle attachments | Rotating or rolling brushes |
| Requires 6 to 12 hours of dry time | Requires 12 to 24 hours of dry time |
| Costs an average of $300 | Costs an average of $240 |
What is Carpet Steam Cleaning?
Also known as hot water extraction, carpet steam cleaning uses heated water to clean your carpet fibers. A carpet steam cleaner injects pressured hot water deep into the rug. As the name implies, the steamer then extracts the hot water back out. The powerful injection of hot water works to dislodge dirt, hair, and even pests from the rug before bringing it back into the machine. While some pro carpet steamers use light chemicals as well, a water-only process is common. Steam cleaning carpets yourself is certainly an option, but you'll get a more thorough clean by hiring a professional.
| Pros | Cons |
|---|---|
| Minimal or no chemicals used | May require pre-treatment |
| Quick drying time | More expensive |
| Kills pests and pest eggs | Not always effective for stains |
Best for: Standard deep cleans for chemically sensitive homes
Pros of Steam Cleaning
Steam cleaning is a mostly—if not entirely—chemical-free carpet cleaning method that is effective and straightforward. The process is more ideal for those sensitive to chemical odors or concerned about a shampoo residue on the carpet fibers.
While you'll still need to wait around 12 hours for your carpets to dry, this is typically a shorter time than carpet shampooing. The power of the pressurized water flow from a steam cleaning can also extract most pests and their eggs, making this a crucial pest-control method.
Cons of Steam Cleaning
If your carpet has stains or particularly caked-on dirt, your local carpet cleaning team may need to spot-clean those areas before passing them with the steam cleaner. Pretreating can lengthen the process, putting it in line with shampooing. That being said, pre-treatment may be necessary for some stains, as the steaming process does not agitate the fibers as much as shampooing.
Steam cleaning also costs about $300 when you hire a pro, a bit more than shampooing. Renting a steamer will also cost a bit more than renting a shampooer.
What is Carpet Shampooing?
Carpet shampooing uses a cleaning detergent and rotary brushes to treat and scrub your carpets. The machine combines warm water with soap and injects it onto your rug as rotary brushes heavily agitate the fibers as you go. This method is ideal for cleaning deep stains, odors, or severe pest issues. Homeowners can choose from a range of both traditional and organic shampoos depending on preference.
| Pros | Cons |
|---|---|
| Less expensive | Can damage fibers |
| Shampooers available for purchase | Chemical residue remains |
| Deeper clean for stains | Takes longer to dry |
Best For: Deeper cleaning and stained carpets
Pros of Carpet Shampooing
Heavily-stained carpets may need the extra care of a carpet shampooer. The chemical cleaner breaks down a larger range of odors and stains than steam alone. The rotating brushes can also reach deeper into tightly packed fibers.
Additionally, carpet shampooers, while pricey to buy upfront, are pretty DIY-friendly when you follow the directions and use the right shampoo for your rug. Even if you hire a professional—which is still recommended—the cost to shampoo a carpet averages $240, a bit less than steaming.
Cons of Carpet Shampooing
Carpet shampooing has a glaring downside—the shampoo itself. While a carpet shampooer pulls as much of the remaining water as possible back into the machine, it cannot rinse all of the soap off of your fibers. Some models allow you to go over the rug with a rinse cycle, but it requires more work and may still not fully remove the fumes. If you're sensitive to chemical cleaners, this makes shampooing less than alluring.
Additionally, the wrong pile setting or shampoo can damage your carpet over time. Over-agitating your fibers or breaking down the fibers can damage the look of the carpet. On top of this, carpet shampooing can take up to 24 hours to dry, particularly if you make another pass with the rinse cycle.
Carpet Steaming vs. Shampooing
There's a time and a place for both carpet steaming and shampooing. Both have their ups and downs, even as steaming becomes more popular for those preferring to skip the soaps and sprays. At the end of the day, either method can be successful when you hire the right carpet cleaning team.
Effectiveness: Shampooing
Steam cleaning vs carpet shampooing are neck-in-neck when it comes to whether they work, but shampooing gets a leg up due to the detergent. The soap breaks down more types of stains and smells than water alone. In the end, you may end up needing to use a shampoo with your steam cleaner.
Long-Term Effects: Steaming
Steam cleaning uses a far gentler process to inject and remove water from your carpet compared to shampooing. Without the rather tough bristles to contend with, you have a better chance of maintaining your carpet over time. The buildup of shampoo on your fibers can also affect their strength, look, and feel as well.
Price: Shampooing
The cost of carpet cleaning is pretty similar in these cases, but you'll pay a little less for carpet shampooing. Renting or purchasing a rug shampooer is also far more common than a steamer, though there are more models on the market each year. Overall, shampooing is less labor-intensive, bringing down the overall price.
Ease: Shampooing
With today's carpet cleaning tools, both shampooing and carpet steaming are quite straightforward, but shampooing is a bit easier and DIY-friendly. The machine does far more of the scrubbing and treatment for you, requiring less attention to tough stains and odors.
Time Required: Steaming
Steaming removes as much of the heated water from your rug as possible, requiring far less drying time than when shampooing a carpet. If you're in a hurry to steam clean the rug before a party, for example, this is a much better bet. Carpet shampooing will also leave a strong soap odor for longer, affecting how much you'll want to lounge in the space after it dries.
Sustainability: Steaming
Last but not least, some homeowners may prefer steam cleaning carpets vs shampooing due to the lack of detergent. While many companies now sell eco-conscious and organic options, the steam-only method is enticing for those looking to keep chemical cleaners out of their home.
