Martin, I have attended many clean offs to find out about all types of systems. Granted there seam to be new or different sysytems each year but I am sure you get my point. I have had just about every dry system presented to clean a carpet under test conditions and not one has ever passed a test by carpet inspectors and the public as to being a better clean than a truck mounted hwe. Portable hwe always come in second place. With this in mind I have never decided to clean any other way other than hwe. Sometimes there is a place for dry systems and they are used. It doesnt alter the fact that it is not the best way of cleaning..... Powdrell, it isnt a few, it is almost all manufacturers that suggest to use hwe. Not only that but some actually say not to use a dry sysytem. Interface tiles say that a dry system can be used but to have them cleaned properly they say to use hwe. Collins and Aikman specify not to use a bonnet machine of any description on their tiles and carpeting and again say only to use hwe. If you apply to clean for C and A you can only use hwe.......Again with all this info I struggle tounderstand why a cleaner wouldnt use hwe as the first arsenal to clean with. With your system Martin, how do you clean tiles, vinyl, mezzanine, concrete etc? If the system you use cant clean these again I would ask why you would use the system. Best, Dave.
