At carpex show I understood that “OZONE carpet cleaning machine” cannot clean carpets without any chemicals. The purpose of using the OZONE is not to clean the carpet, but to sanitise it.
I think that any carpet cleaning machine, which uses a really hot water/steam, sanitises the carpet.
So is there a real demand for “OZONE assisted carpet cleaning”? I personally do not think so. Because places, which have to be kept hygienically clean, chose that type of flooring which can be maintained easy and inexpensively and it is not carpet.
