In a perfect world, you'd never have to clean anything manually. The dirty dishes would rinse themselves, and the laundry would stack into perfectly folded layers in your closet. All the dust and dog hair in your living room would collect into a pile and then jump into the trash can...which would also empty all by itself.
*Sigh.* That sure does sound nice, doesn't it?
Unfortunately, we do not have that kind of luxury. Unless you can afford to hire a cleaning service to tidy home every single day, you've probably had to deal with a fair number of messes in your life.
So you have to clean your house (or probably should, anyway), but it doesn't have to be a gigantic chore that looms over you for your entire life. There are ways to make it easier!
