When using a pad washer to clean I'm getting great results on the cleaning part but the drying part isn't so good. How dry should the pad be when done with the cleaning process? Are you able to put the pad back to work immediately? I do the extra step of running the pad on the domed plastic attached to the top of the bucket. Do you switch the pad to a rotary and spin it wide open? A PC would most likely destroy the pad if used full speed.
