How often should I shampoo my rugs?

I just moved and I have beautiful new carpeting. I already make people leave their shoes at the door. I also heard too much shampooing attracts more dirt. How often should I shampoo my rugs?How often should I shampoo my rugs?
As long as they wear socks, you should be good shampooing once a year or so, but if you allow barefoot, the carpet people told me that the oil from your skin will make the dirt stick more to the carpetHow often should I shampoo my rugs?
It just depends on how much company you have. I'm sure everyone who walks in your door won't remove their shoes. I bought a carpet shampooer and use it about every 3 months or so. BUT................I have alot of people in my house!
if you make people remove thier shoes like we did in Hawaii and you vacuum daily and I mean daily no need to shampoo ,the carpet has protection from stains that can be removed in the shampooing process


personally I would not have carpet as it is nasty stuff ,dirt ,allergens etc but if you follow the program you are on it should be fine


removing shoes at the door is ancient Japanese custom
