I'm with you for size, just more frequent.A dedicated floor dust mop on an extension pole is what I use every 2 months. I presoaked it for a week in bleach to dissipate any chemicals that might have been on it initially.
I use 4"x10" acrylic scrub pads on an extension of PVC to do little touch ups every couple of days. Once or twice I week I just get in and scrub everything by hand.
