Because I am awake at this ungodly hour and have just read that endless other thread about slack things you do, I saw this:
Some people don't have bits that need mopping? My whole house is floorboards and tiles (we have no carpet) so I mop. In my case, I don't need to own a vacuum cleaner.
I have only ever known to vacuum before mopping to get all the chunky bits (like, crumbs, hair and dust). Wouldn't mopping without vacuuming first just push all the chunky bits around the floor and even though you have mopped, the floor would still look....errrrr.....dirty?
Are my mother and I (and a couple of other people I know) the only ones who always vacuum before they mop?
