Karl, what Simon does is what would appear to be, run a very succesful cleaning company. I never said the RX20 would ruin a carpet, I just said it would void any warrenty or guarentee the carpet had, huge difference. There is a company which I wont name that says how good their machines are on carpet tiles. Yet the carpet tile company stipulates in writing that the said machines should not be used on carpet tiles. But still the machine is made and is indeed used by many people on here.
Muck spreaders are used daily, even though they too are stipulated as not to be used on certain types of carpet. Yet still they clean hundreds of yards of carpets. These machines will always be made and while we, miss guided as it is in my opinion continue to buy them and think we clean, then the manufacturers will still make and sell them.
Best, Dave.
