Hi C.,
I have cleaned houses for a living for many years and have found some tried and true things for hardwood floors. I had a house will all hardwood too, so I've lived it.
First, a good vacuum with a hardwood floor attachement. Do not sweep your wood floors, all you're doing is moving the dust and hair around. I don't like the Rumba or automatic type vacuums, they are round, corners are not. Vacuum your floors first, it gets up all the hair, dust, crushed cereal and toast crumbs.
Second, microfiber, microfiber, microfiber. It's going to be your best friend. Don't bother with a cheap version of a microfiber mop. Spend the money and get a good quailty microfiber pad. The mop handle its self doesn't matter, the mop head does. Good quality microfiber is amazing. Make sure you have more than one head, you will want to change them often. Use them to wet mop your floors when needed or to do a dry mop/quick pick up when you don't want to take the time to break out the vacuum.
Do not use a steam cleaner on wood floors. Steam/moisture will expand the wood each time you clean the floors. When it dries and contracts, the wood is damaged. Over time, your floors will be ruined.
Don't bother with swiffer wet jets or anything like that for cleaning, they don't do the job that microfiber does, and worse, they leave a coating on your floor that only attracts more dust and dirt. Good old microfiber, water and a little disinfectant will do the trick. I use lemon Pine-Sol, I like the way it smells.
One quick note on microfiber. Microfiber is designed to pick up dust and dirt by naturally using a bit of the static electricity in the air to grab the dirt. Wash them in the washing machine, but do not use fabric softener. You can dry them in the dryer if you choose, but no static dryer sheets. I hang dry my rags and mop heads. If you use fabric softener and/or dryer sheets, they coat the microfiber. Dryer sheets are designed to repel dust, (hence that's why we use the used ones to dust our tv and computer screens). The coating on the microfiber will repel dust, not attract it.
I'm happy to offer any other suggestions if you need more answers. Happy cleaning!
