Nigel, knowing you as I do I would never call your credentials into question. However I also know you own a rotary machine
Doug, what you say may well be true but how often has any carpet cleaner been asked by their customer if they are using methods which will invalidate any sort of guarantee
(or warranty maybe?) By the time we get to see any such carpets they are usually far outside of such territory, or if they are still within a warranty/guarantee period the reason we'd need to be cleaning them would very possibly mean the warranty has already been broken!!
I've been asked about this in a few situations and they are always stain removal jobs on nearly-new carpets, which aren't the kind of thing where a rotary is needed anyway.
Tony, have you seen the SERIOUS damage someone can do with just about any machine or tool if they don't know what they're doing? I've see more carpets damaged by vacuum cleaners than anything else, maybe we should get them banned
As someone who's also built my business from the ground up without help from anyone else, I have just as much right to voice my opinion as any other forum user
Maybe my wording was a little provocative but hey, we are all passionate about what we do.
p.s. I've got a spare rotary for sale if you want it
