Started dabbling with carpet cleaning around 1989 with a small stimvak i bought second hand.
On about the third job it caught fire and dumped all its water on the lounge carpet, needless to say i never saw those customers again

I can still see the look on their faces now, they were elderly and didnt have a clue what i was doing.
Come to think of it neither did I

Funnily enough it didnt put me off

Later bought a second hand numatic ct570 and launched myself as a professional carpet cleaner

Its amazing im still here really.
