Deep Extraction Carpet Cleaning: What It Is and When You Need It
Deep extraction is a hot water method. A technician pre-treats the carpet, rinses it with heated water under pressure, then pulls the water and the soil it has loosened straight back out with powerful suction. A vacuum only lifts dry dirt from the surface. A spot cleaner only treats the mark you can see. Extraction is the one that reaches the soil packed into the base of the fibres. In Sherwood Park and Edmonton, we price it per room, from $49 to $79 CAD, with a $129 minimum charge.
This guide explains how the process works, how it compares with spot cleaning, what a good job looks like, and when extraction is the wrong tool.
TL;DR
Deep extraction means pre-spray, hot water rinse, strong suction and a dry pass. It removes embedded soil, allergens and residue that vacuuming and spot cleaning leave behind.
Spot cleaning is for fresh spills. Extraction is routine maintenance for the whole carpet. Most homes need both.
Truck-mounted machines pull much more water out than portable rentals, which matters for dry time and for leftover residue.
Carpet that has been flooded or soaked for a long time is often a replacement job, not a cleaning job.
Our carpet cleaning is $49 to $79 per room, and the minimum charge is $129.

What deep extraction carpet cleaning actually is
The Carpet and Rug Institute’s CRI 205 residential standard defines an extractor as equipment that uses pressure, water or cleaning solution, and suction to pull deeply embedded soil or stains out of carpet. A vacuum, by contrast, collects dry soil from the surface.
Professionals usually call the method hot water extraction, and sometimes steam cleaning, although no actual steam is involved. The steps look like this:
Inspection and vacuuming. Loose grit comes out first. Dry soil turns to mud once it meets water.
Pre-treatment. A separate pre-spray goes on to loosen oils, traffic lanes and stains. It needs a few minutes of dwell time to work.
Hot water rinse and extraction. Heated water is driven into the pile and pulled back out at once, carrying the loosened soil with it.
Dry pass. The technician goes over the carpet again with the solution valve closed to remove as much leftover water as possible.
Final check. Grooming the pile, checking for spots that need a second treatment, and advising on drying.
Step 4 is the one that gets skipped. It is also the main factor in how fast the carpet dries.
Spot cleaning versus deep cleaning
Spot cleaning and extraction do different jobs. People often treat them as rivals, but they work together.
Spot cleaning | Deep extraction | |
Purpose | Reacting to a fresh spill or mark | Maintaining the whole carpet |
Reach | Surface of the visible area | Base of the fibres across the room |
When | Straight away, within minutes | On a schedule, or when carpet looks dull or smells |
Allergens and oils | Not addressed | Washed out with the soil |
Risk if overdone | Residue rings, rapid resoiling | Over-wetting only if the dry pass is skipped |
Spot cleaning is the right first response. Blot a spill, never rub it, and work from the edge inward. But a spot clean does nothing about the oils and grit that build up in the traffic lanes where nobody notices them. That hidden soil acts like fine sandpaper under foot and slowly wears the fibre down. Sooner or later a freshly spot-cleaned patch also looks cleaner than the carpet around it, which is a sign the rest is overdue.
Here is a rule of thumb we use with customers:
One spill, carpet otherwise fresh: spot clean.
Spot keeps coming back, or looks clean next to dull carpet: extraction.
Pet accidents: neither on its own. Urine soaks into the pad, so it needs targeted treatment. More on that below.
Why it matters for allergens and air quality
Carpet holds dust mites, pet dander, mould spores and the grit tracked in on every Alberta winter boot. Health Canada’s healthy home guide recommends vacuuming weekly, using a HEPA-filter vacuum where possible, and wiping hard floors with a wet cloth or mop. Good vacuuming handles the surface layer. It does not wash out what has worked its way down.
HealthLink BC’s guidance on dust, dust mites and allergens makes the same point from the allergy side: reducing what builds up at home is part of managing symptoms. If anyone in your household has asthma or allergies, a periodic deep wash of the carpet is a sensible part of that routine, alongside the weekly vacuuming. We would not promise any health outcome from cleaning alone. For persistent symptoms, talk to your family doctor.
Dry time is the part to ask about
The thing that separates a good extraction job from a poor one is how much water is left behind. The CRI 205 standard says carpet should be dry within 12 hours after hot water extraction. Carpet that stays damp past that point raises the risk of mould and mildew growth.
Three things control dry time:
Suction. A truck-mounted unit sits outside and runs a long hose in. Its power and heat are far beyond a portable machine. We use truck-mounted equipment with roughly ten times the suction of a typical rental unit.
The dry pass. Extra passes with no solution flowing remove residual water.
Airflow. Run fans or the furnace fan, and open a window slightly if the weather allows. In an Edmonton-area winter, with dry indoor air, carpet tends to dry well, but humid summer days slow it.
We guarantee a fast dry time on every job. For a closer look at what to expect, read our guide to dry carpet in 6 to 12 hours with hot water extraction.
Why rental machines often disappoint
A rental machine looks like a bargain, but three things tend to go wrong:
Weak suction. Portable units leave more water in the carpet, which means longer drying and a higher risk of musty odours.
Detergent in the clean-water tank. Many people pour cleaning solution into the tank, so the carpet gets over-concentrated soap and not enough rinsing. The sticky residue then attracts dirt, and the carpet resoils fast. Professional systems apply pre-spray separately and then rinse with clear water or a specialized rinse.
No pre-treatment strategy. Grease, pet urine and traffic lanes need different products. A single pass with one solution rarely handles all three.
Portable equipment also has a legitimate role. In apartments or upper-floor units where a truck cannot reach, a cleaner may have to carry in a portable unit. If that applies to you, confirm the machine type when you book. Expect a higher minimum charge and possibly a longer dry time.
What deep extraction costs in Sherwood Park and Edmonton
Our prices are published, and per-room or per-item. All amounts are in Canadian dollars:
Item | Price |
Carpet cleaning | $49 to $79 per room |
Hallway | $35 each |
Staircase | $45.50 each |
Extra steps | $3.50 per step |
Walk-in closet | $22.50 each |
Landing | $10 each |
Waste disposal fee | $20 |
Minimum charge | $129 |
A worked example: two bedrooms at the bottom of the range would add up to $98, which is under the minimum, so the job would be billed at $129. That is why bundling rooms makes sense. Add a hallway and a staircase to those two rooms and the job is no longer just a minimum-charge visit. You can see the full list on our pricing page.
For context, one 2026 cost guide puts hot water extraction at $25 to $75 per room, or $0.20 to $0.40 per square foot, with a three-bedroom home at $150 to $300. Treat figures like these as a rough benchmark only, since they depend on the region, the operator and the equipment. Always compare what is included: truck-mounted or portable, pre-treatment, dry pass, and whether there are extra fees.
Our pricing has no hidden fees. The only add-ons are the ones listed above.
Our perspective: extraction is maintenance, not rescue
We are a family-owned business in Sherwood Park, and we have cleaned carpets in more than 1,000 homes. A few things we have learned shape how we work.
First, most customers call us when a carpet looks bad. The better time is before that. Soil that sits in the base of the pile cuts the fibres every time someone walks across it. A scheduled deep clean costs less than a replacement, and it keeps the carpet looking better between visits. If you want to stretch the gap, our tips on carpet care between professional cleanings cover vacuuming habits, doormats and shoe rules. And if you are not sure how often your household needs it, see our guide to how often to clean your carpets.
Second, products matter as much as machines. We use eco-friendly, family-safe products, because the people who live on the carpet are often small children and pets. Rinse quality is also what keeps the carpet from resoiling.
Third, we would rather tell you that a carpet cannot be saved than take your money. Water damage from flooding or a long-term leak is a replacement conversation, and we say so honestly. Extraction is for maintenance.
Finally, the same discipline applies to commercial spaces. Facilities that run a steady maintenance routine, such as the daily and weekly cycle described in this guide to epoxy floor maintenance for facilities, spend less on restoration later. Carpet follows the same logic. For offices, we offer after-hours appointments so your staff and customers are not disrupted.

When extraction is not the answer
Water damage and mould
Health Canada says there is no safe level of mould in a home and that the focus should be on controlling moisture. The same page says you can generally clean small and medium-sized areas of mould yourself, but you should consider professional help for extensive growth. If a carpet has been flooded, or a leak has soaked it for days or weeks, cleaning it to a safe standard is often not possible, and replacement is the safer path. In that case call a water-damage restoration specialist, and your insurer if it applies. Do not book a routine clean over mould.
Pet urine
Urine goes through the carpet into the pad. Surface extraction alone can leave the odour behind, and it can return on humid days. We use UV inspection to find stains that the eye misses, then treat them with enzyme-based solutions. See our pet stain and odour treatment service, or read about urine and odour removal in Edmonton homes. If pet hair is the main problem, our guide to pet hair in carpet by pile type is a better start.
Light soot and greasy stains
Light soot can sometimes be blotted. Greasy soot smears and sets if you rub it, so do not rub. Our note on soot on carpet explains where DIY ends and a professional visit begins.
Warranty and certification
Many carpet manufacturers require regular professional cleaning to keep a warranty valid, and they may specify the method. Read your warranty before you book. The Carpet and Rug Institute runs a Seal of Approval program for cleaning products and equipment, which the CRI 205 standard describes as an important resource for consumers. Ask any cleaner what machine and products they use, and whether they meet the manufacturer’s requirements.
How to prepare for your appointment
Vacuum the day before if you can. It takes minutes and improves results.
Clear small items, and tell us about stains and what caused them.
Lift delicate or antique furniture off the carpet, or tell the technician about it.
Plan for drying: keep shoes off the carpet and run fans or your furnace fan afterwards.
Tell us about pets, so we can check for hidden stains.
Beyond carpets: other surfaces we clean
The same truck-mounted approach applies elsewhere in the home. We clean upholstery from $79 per piece, area rugs from $49 per rug with fibre-specific treatment, and tile and grout. Landlords turning over a unit often combine several of these in one visit, and offices can use our commercial carpet cleaning. Commercial work has no published price, so you will need a quote.

We serve Sherwood Park, Edmonton and nearby communities, with truck-mounted hot water extraction, eco-friendly products, transparent pricing and a 100% satisfaction guarantee. You can book online or look over our carpet cleaning service page first.
FAQ
What is extraction carpet cleaning?
It is a method that sprays heated water and a rinse into the carpet and pulls it straight out with strong suction. The water carries the loosened soil, allergens and residue with it. The Carpet and Rug Institute’s standard defines the equipment as using pressure, water and suction to remove deeply embedded soil.
How much does a deep clean cost?
It depends on the provider and the size of the job. With us, carpet cleaning is $49 to $79 per room, hallways are $35 and staircases are $45.50, with a $129 minimum charge. Other providers price differently, so compare what is included.
How do I deep clean heavily soiled carpet?
Vacuum thoroughly, pre-treat the heavy traffic lanes, then rinse and extract with a dry pass at the end. Heavy soil often needs a professional truck-mounted machine, because a rental unit may leave residue and too much water. If the soiling comes from flooding or a leak, ask a restoration specialist first.
What is the difference between a regular carpet cleaner and a deep carpet cleaner?
A regular cleaner, such as a vacuum or spot product, handles the surface or a single mark. A deep cleaner uses hot water extraction to wash the full depth of the pile. For a household, the best routine is weekly vacuuming, quick spot treatment and a scheduled professional extraction.
