How clean are you?

I grew up in a really clean house. So clean that you literally could eat off the floor and it was probably more sanitary than most peoples kitchen counters. My mom is a nut about cleaning. Last year she spent an entire 3 days cleaning out the grout between her kitchen tiles. She put foaming bleach on every single grout line and scrubbed until it was abnormally white. And for her birthday all she asked for was a power washer to clean out the concrete seams in her driveway. Who does that? Apparently my mother. Well, because of her crazy obsession I've always wondered what is normal or sufficient in terms of cleanliness. How often do you clean your bathroom? How often should you change your sheets? Carpet cleaning? When do you replace your rugs? My mother said you should never go a week without deep cleaning your bathroom (for those who are not familiar with her standard of "deep", we are talking about soft scrub, sponges, down on your hands and knees scrubbing the floor clean). Changing your sheets is the same-- not a day over a week. Do people really pay attention to grout? These are the questions that are driving me insane with worry when I don't make it to cleaning my bathroom for a week and a half. So please share with me your feelings about cleaning and what you were taught.

p.s. A little note for my former roomates: You are probably thinking, "Katie clean?, her room was a fire hazard with all her clothes strewn about, but I have to say those years were my rebellion from so much cleaning as a child. I'm much better now!
