has anyone like me gone from window cleaning into carpets?
Judging by the amount of windies who come on here asking what machine and chemicals to buy so they can be a carpet cleaner, I'm surprised there's any window cleaners left.
You should be on here mid winter when they are all naffed off with the cold & rain, it's like those wildebeest you see on telly, migrating across the Serengeti in their thousands.
The "crocodiles in the river" that kill most of them are the facts that the kit costs an arm and a leg (if you're serious about it), you actually have to train & learn lots to do the work (costs a lot & takes years) and customers are much harder to come by (marketing costs a lot).
Hence the reason so many 2nd hand portables pop up on ebay.
