Hot water extraction injects heated solution and immediately vacuums it back out. Low-moisture or dry systems use compounds, bonnets or encapsulation chemistry with far less water.
We use both. What decides it is the carpet in front of us and what the customer needs from the room afterwards.
The short version
- Extraction removes more embedded soil, full stop
- Low-moisture dries in under an hour, which matters commercially
- Some delicate and natural fibres cannot take heavy wetting
- Encapsulation suits frequent maintenance on commercial carpet
- Extraction is the right call for restorative and one-off deep cleans
Where hot water extraction wins
For deep, restorative cleaning it is not close. Extraction physically flushes soil, allergens and residue out of the fibre and removes them from the building. Pet contamination, heavy domestic soiling and neglected carpets all need it.
Where low-moisture wins
Offices, shops and hospitality floors that must be usable within the hour. Encapsulation chemistry crystallises soil so it is vacuumed away over subsequent days, which suits a maintenance cycle rather than a rescue.
It is also the safer option on fibres that shrink, brown or watermark when wet — viscose being the obvious one.
Using both together
The practical approach for many commercial clients is periodic extraction as the deep clean, with low-moisture maintenance in between. It keeps appearance consistent without shutting an area down every time.
- Quarterly encapsulation on circulation routes
- Annual or biannual extraction across the whole floor
- Spot and entrance-matting work as needed between visits
