If your carpets are looking dull, dirty, or stained, you’re probably wondering whether you should steam clean or shampoo them. It’s one of the most common questions we hear from homeowners across West Covina, Covina, Diamond Bar, San Dimas, Azusa, and the rest of LA County.
Both methods sound similar, but the science behind them—and the results—are very different. Choosing the wrong method can leave your carpets wet for days, cause reappearing stains, attract more dirt, and even shorten the life of your carpet.
This guide breaks down the pros and cons of both methods, explains which one professionals prefer, and helps you choose the best cleaning method for your home.

What’s the Difference Between Steam Cleaning and Shampooing?
Steam Cleaning (Hot Water Extraction) uses high-temperature water, pressure, and powerful extraction equipment to remove dirt, bacteria, and stains from deep within the carpet fibers and padding.
Carpet Shampooing uses a detergent-based foam applied to the carpet surface. The foam agitates dirt, but much of the residue stays behind unless removed by extraction.
Both methods can improve the appearance of carpet, but the level of cleaning is not the same.
Steam Cleaning (Hot Water Extraction)
How It Works
Steam cleaning uses hot water—typically 200°F to 230°F—combined with specialized cleaning solutions. High-pressure jets penetrate deep into the carpet fibers, and a high-powered vacuum immediately extracts the dirt, oils, allergens, and moisture.
Pros of Steam Cleaning
- Deepest cleaning method available — removes dirt, oils, bacteria, and allergens from deep inside the carpet
- Recommended by major carpet manufacturers like Shaw and Mohawk
- Safe for kids and pets when done professionally
- Eliminates odors instead of masking them
- Extends carpet life by removing abrasive particles
- Removes stains effectively including food, drink, and pet stains
- Great for allergy sufferers thanks to high heat sanitation
Cons of Steam Cleaning
- Carpet remains damp for several hours (typically 4–8 hours)
- Requires professional equipment for best results
- Not ideal for extremely delicate or antique rugs (those require special care)
Best For:
- Homes with kids or pets
- Allergies or asthma concerns
- Pet odors and pet accidents
- Homes with heavy foot traffic
- Annual whole-house deep cleaning

Carpet Shampooing
How It Works
Carpet shampooing involves applying a foamy cleaning detergent to the carpet surface and scrubbing it in with a machine. The agitation loosens surface dirt, but the method does not flush contaminants out of the carpet backing or padding.
Pros of Carpet Shampooing
- Improves surface appearance of carpet
- Can remove light surface stains
- Cheaper than steam cleaning
- Good for very temporary cosmetic improvement
Cons of Carpet Shampooing
- Leaves detergent residue which attracts more dirt
- Stains often reappear within days due to wicking
- Does not sanitize or kill bacteria
- Does not remove odors, especially pet odors
- Can leave carpets wet for 12–24 hours
- Not recommended by most carpet manufacturers
Best For:
- Short-term rental properties between tenants
- Quick cosmetic improvement
- Very low-budget situations
Steam Cleaning vs. Shampooing: Side-by-Side Comparison
| Feature | Steam Cleaning | Shampooing |
|---|---|---|
| Cleaning Depth | Deep (removes embedded dirt, bacteria, oils) | Surface-level only |
| Odor Removal | Excellent | Poor (masks odor) |
| Dry Time | 4–8 hours | 12–24 hours |
| Stain Removal | Highly effective | Moderate |
| Manufacturer Recommended? | Yes | No |
| Long-Term Results | Extends carpet life | Residue speeds up re-soiling |
| Sanitization | Kills bacteria & allergens | No sanitizing power |
Which Method Is Better for Los Angeles County Homes?
Most LA County homes—including those in the San Gabriel Valley—experience:
- Heavy foot traffic
- Dust from dry climate conditions
- Pet hair and dander
- Outdoor pollution
- Allergy-prone seasons
For these reasons, steam cleaning is nearly always the better choice. It removes allergens, sanitizes the carpet, and pulls dirt from deep within the fibers.
Shampooing should only be used in situations where appearance—not sanitation—is the goal.
Why Professionals Prefer Steam Cleaning (Hot Water Extraction)
Professional carpet cleaners—including our team at Buyher’s Carpet & Upholstery—use steam cleaning because:
- It’s the only method that cleans all the way down to the carpet backing
- It removes pet odors rather than covering them up
- It sanitizes carpets using heat
- It leaves no sticky residue behind
- It is eco-friendly and safe for pets and children
- It follows manufacturer warranties
For most homes in West Covina, Covina, Diamond Bar, Azusa, Glendora, and Pomona, steam cleaning provides longer-lasting, healthier results.
When Shampooing Might Still Be Useful
While steam cleaning is the superior method, there are rare situations where shampooing still serves a purpose:
- A very old carpet nearing replacement
- Apartment move-outs where appearance is the only concern
- Budget emergency cleaning
- Spot treatment for specific areas with mild surface stains
However, even in these cases, the results are temporary.
How Often Should You Steam Clean Your Carpet?
- Every 6 months if you have pets or kids
- Every 12 months for low-traffic homes
- Every 3–6 months for rental properties or commercial spaces
This routine keeps your carpets fresh, sanitary, and long-lasting.
Final Verdict: Steam Cleaning Wins for Long-Term Results
If your goal is a healthier home, cleaner carpet, and a longer-lasting floor, steam cleaning (hot water extraction) is the clear winner. It removes deep dirt, odors, bacteria, allergens, and stains—without leaving residue behind.
Shampooing may improve appearance temporarily, but it doesn’t deliver the deep cleaning most LA County carpets need.
For the best results in West Covina, Covina, San Dimas, Diamond Bar, Azusa, and surrounding areas, trust a professional steam cleaning service.
