Albertporter, I haven't tried a felt-type brush since back in the days of the Discwasher D4 system. The Milty Duo-Pad does look interesting. I didn't see that it came with a brush for cleaning the pads?I use the red plastic cover of the Duo-Pad for that purpose.
The cover must be removed to access the pad. When the pad has completed the job of picking up lint, I use the edge of the cover to sweep the pad clean.
The Milty Duo-Pad works much better than the Disc Washer, at least as I remember.
