What would you advise Chris to try instead of carpet cleaning.
Every business you try to start up has its headaches - some more then others perhaps. So lets be positive about things.
I started doing carpet cleaning 15 years ago when I was 45 - still making mistakes (especially advertising) but it wasnt until 4 years ago I started to get it right and now, especially after joining these internet forums, I have got it a lot better (thank you everyone for giving me the opportunity to draw on your experiances).
I have learnt inparticular that it is important to vac, prespray, agitiate, waiting time, extract.
So you need a good vac cleaner (I have a Karcher similar to the Sebo and Lind), get the right prespray fluids (microsplitter etc), good brush (mechanical is desirable but more expense), patience (waiting time), and a extraction machine as already posted previously ie twin vac, 135psi min.
Couple thousand pounds should get one going - add on as you get established.
As I said in my previous post - get cleaning neighbours, friends, relatives for experiance and referals - dont do freebies, good discounts yes, just to get going.
