If you inexperiaced in carpet cleaning, be careful.
You may be sold something you dont want/need - and that is a general statement and not just aimed at Hose.
Host is a cleaning system in itself, but a bit specialised.
Hot water exteaction is the main way of extracting dirt from a carpet.
If you doing a lot of commercial low profile tiles etc that maybe consider a rotary machine - bit like some of the buffers you see in shopping malls but lower rpm (you can burn a carpet with high speed rotary).
A training course for you is my recomendation if you serious about carpet cleanng.
Have a chat with some other c/cleaners down in south wales. One very local to you may not want to talk, so go a bit further afield and see if you can be a unpaid helper for a day or two.
Carpet cleaning is not a pot of gold, best see if you want to do it before you dive in.
