John G. has finally zeroed in on why some pads don't last and others do...........The pad driver. This is something I've suspected since I started to use OP equipment.
None of the machines on the market have the same style pad driver. Its unrealistic to expect pads to last or work the same on all machines.
No one style pad driver will do it all. The ability to run different style pad drivers on a machine will make for a happier operator.
Thinner cotton, Glads or whatever should work better with velcro drivers. Thicker pads, Tuways, Micro or whatever should work better with a bristle driver.
I preferred the bristle driver in our commercial carpet cleaning biz because of the pads we used. At the time we used mostly Tuway synthetic pads or a floor pad. These drivers are also great for the occasional VCT if you do any of that. We did own a machine with velcro driver and it ran the thinner cottons well.
