Thanks Karl @ CMS for this info. As i said i was reading a topic the other day, and Bob who uses the system was getting quite shirty about the critiscism. He did eventually go on to elaborate about how he uses the system in the local hospital because when he won this contract, it was stipulated that his system of cleaning, echo the previous contractors.
I run a new truck mount, and believe hwe to be about the best and the most universal. When on training courses at prochem, the various systems were explained thus; the pad system would be used on light maintenance, whereas the hwe system would be used for carpet restoration, ie a very dirty carpet.
When someone asked about hwe being used across the board from light maintenance to restoration, the answer was yes. From this point, my mind was made up.
Once again, thanks for your answers
