The electrostatic cleaners are great but the refill pads are pricey. I've been using washcloths (old ones or cheap new ones) for dry dusting and picking up hair. I spray a dry cloth with Endust on both sides and when one side's dirty I turn it over and use the other side. For wet mopping add a little ammonia or dishwashing liquid and 1/2 cup of water to an empty baby wipe container and put five or six washcloths in for ready to use wet pads as needed. Throw dirty cloths in wash as needed. Never by replacements again. Even cut old towels to fit and use the same way.
