Old ways of cleaning vs. new ways. Which is better?

Now we have all these innovations in cleaning to make our job cleaning the house easier. Swiffer mops (and sweepers), Lysol wipes, Windex wipes, toilet brushes w/ disposable heads (some that can even flush down the toilet!), ect... I hate to spend the extra money that these things cost, but I find myself feeling the need to use them just for the fact that they are more sanitary in many instances. I keep hearing that sponges harbor bacteria, so I use the Lysol wipes. I can't stand the thought of keeping and reusing something that I've put in my toilet, so I use the ones with the disposable heads. Mop heads get really gross, so I use swiffer. I find that I spend more money for these things, and money is tight with us, but I don't know any other way that is so sanitary. What do you think?
