Carpet cleaners around the South West offer two main methods, and the names don’t explain much. Here’s the plain-English version of what each actually does.
Steam cleaning (hot water extraction)
Heated water is injected deep into the carpet pile under pressure, dissolving the soil bound to the fibres, then immediately extracted — dirt, allergens and moisture together. Despite the name, it’s precisely controlled hot water, not billowing steam.
Strengths: cleans the full depth of the pile, not just the surface; removes allergens and odour sources rather than covering them; it’s the method most carpet manufacturers recommend for periodic deep cleaning. With professional-grade extraction, carpets are typically walkable again in hours.
Watch out for: cut-price operators using weak extraction and heavy detergents — that’s where the “carpet stayed wet for two days and got dirty again fast” stories come from. The problem is the operator, not the method.
Low-moisture (“dry”) cleaning
An absorbent compound or an encapsulating solution is worked into the carpet, binds to surface soil, and is vacuumed away. Minimal water, very fast dry time.
Strengths: quick turnaround for spaces that can’t be out of action, and suitable for a small number of delicate or glue-down carpets that shouldn’t take moisture.
Limits: it cleans where it can reach — the surface. Deep-set soil, pet accidents that have soaked through, and trapped allergens largely stay put.
So which one?
For a home that wants a genuine deep clean once or twice a year: steam cleaning, done properly with strong extraction. For a commercial space needing a fast surface refresh between deep cleans, low-moisture has a real place. If someone quotes you a method without looking at your carpet first, that’s the red flag either way.
We use professional hot water extraction for most Bunbury homes — and if your carpet genuinely needs a low-moisture approach, we’ll say so at inspection rather than force the wrong method onto it. Details on our carpet cleaning page, or call 0401 990 215.
