There is no single method that suits every carpet. The right choice depends on the fibre, how soiled the carpet is, whether it is a home or a commercial site, and how quickly the floor has to be back in use. Here are the five methods you will actually be offered in Sydney, what each one does well, and where each falls short.
1. Hot water extraction, usually called steam cleaning
Heated water and a pre-spray are injected into the pile under pressure, then immediately vacuumed back out along with the suspended soil. It is the most thorough method available and it is what carpet manufacturers generally specify in their warranty conditions. Done with a truck-mounted unit it reaches temperatures and suction levels a portable machine cannot match. Drying takes roughly three to five hours. This is the method we use on most residential jobs, and it is explained in full on our steam carpet cleaning page.
2. Dry cleaning, or very low moisture cleaning
A slightly damp absorbent compound is worked into the pile with a machine, given time to bind with the soil, then vacuumed away. The carpet is walkable almost immediately, which is why it suits offices, retail floors and anywhere that cannot be closed for half a day. The trade-off is depth. It lifts surface and mid-pile soil well but does not rinse the fibre, so heavily soiled carpet will not come up as clean as it would with extraction.
3. Encapsulation and foam cleaning
A foaming detergent is applied and agitated, and as it dries it crystallises around the soil particles so they can be vacuumed out. It sits between shampooing and dry cleaning, uses very little water, and is popular for commercial maintenance cleans between deeper services. It is a good interim method and a poor substitute for an annual deep clean.
4. Bonnet cleaning
An absorbent pad is spun over the carpet surface with a cleaning solution. It is fast and cheap, and it is genuinely useful for maintaining the appearance of commercial loop pile in a lobby or corridor. It is not a deep clean. Because it only touches the top of the pile it can also push soil downward, and on cut pile carpet it risks distorting the fibre. We do not recommend it for homes.
5. Shampooing
The oldest method still in circulation. A foaming shampoo is scrubbed into the carpet with a rotary machine and the residue is vacuumed once dry. It leaves the carpet looking bright straight afterwards, but detergent residue tends to remain in the fibre and residue attracts soil, which is why shampooed carpet often resoils faster than it did before. There are better options now for almost every situation.
Which one should you choose?
For a typical Sydney home, hot water extraction. For a busy office that cannot shut down, a low moisture method with periodic extraction. For wool or a delicate natural fibre, extraction with controlled moisture and pH-appropriate chemistry, never a heavy soaking. For a valuable or antique rug, none of the above in place, since those are better handled through a proper rug cleaning process off site.
Whichever method is used, the preparation is the same
Every deep clean should begin with a thorough dry vacuum. Skipping it means dry soil turns to mud the moment moisture is applied, and no amount of extraction fully recovers from that. The pre-spray also needs dwell time to break down oily soil before agitation. A cleaner who moves straight to the wand is rushing the part that does most of the work.
Add-ons worth knowing about
Fibre protection can be reapplied after cleaning to slow future staining, which is most useful on stairs, hallways and light-coloured carpet. Our Scotchgard protector page covers what it does and does not do. Upholstery uses the same extraction principles on a smaller scale, so it is worth combining with a carpet booking through our upholstery cleaning service.
