Bob, I've been OPing about 2yrs now. Glad pads are the best, just the quality is all over the place. Steve at Vacaway has some durapads that are good. The microfiber pads on the Trinity have a lot of potential.
The rotary vs OP has little to do with the 1800 opm vs 175 rpms. The real difference is the random orbits vs circles. The random orbits clean all sides of the fiber at one time. To get the same clean from a rotary the operator needs to go E-W and N-S with a glad pad or SLOWLY with a soft brush. The only chems to use are CCS or Vacaway. Specifically Genie's Potion, Padcap Pro and Blaze or Intensity Green, Quantum Green, Intensity Red, Blast, Pee Radicator, Encap Green, Cyclone, and Spot N Boost (regular and green).
