If you think all carpets are cleaned the same; you clearly aren't a professional carpet cleaner of any semblance.
I may not be a professional, but I've been carpet cleaning for 24 years and have always used the same method to clean a carpet. If I was doing something wrong I would have gone out of business long ago.
Are you a professional because you've attended courses?

Not at all. I'd say there is no unambiguous definition to the term 'professional'. It certainly doesn't come from the training because someone can undertake all the training in the world and still be crap (in practice and in attitude). The professionals in this industry (if there are professional carpet cleaners) are those who behave professionally in the service they provide, and the business they run.
I do agree though that this thread is simple, GCSE-level forum flaming.....

It doesn't upset me personally because I'm new to this lark (relatively) and I chose carpet cleaning as a lifestyle choice, not because of any dillusion of grandeur. I left the corporate rat race, endless travel up and down the country, company politics and a large salary (!) to do this menial cleaning ........ it's fun!
