reduce one slice of the pie (sinners circle) and you need to increase one of the others. so if you work without heat you need to increase say mechanical action. or dwell times. that.s why people use microsplitter with these machines
Ian I dont think thats the reason , as you can buy a inline heater if you need heat, or you can use a decent crb .
I think that the majority of scorpion users in my experience are dedicated cc that strive to clean carpets to the best of their abilities in a eco manner and that's a reason they may use microsplitters ,also they tend to work in a market area where they are cleaning carpets that are not that dirty, so there is no necessity for heat, but strive for faster drying times .
They tend to work on a repeat work culture instead of the high numbers game that allows them to avoid advertising cut price offers and advertising low cost fb ads.
this doesn't apply to all but from what I have seen it seems to be the case . I don't own one and still don't use heat very often
