Fact is carpet is filthy. I don't care if you vacuum it every 2 hours, and shampoo it every day. It is just filthy. You can't get it clean. It may look clean, but it is not. I would not have a camper with carpet, and I will not have carpet in my house. tile, and hardwoods are so much easier to keep clean it is just unreal.
Also. for you folks with allergies. You really think that filthy carpet is helping you? Nope, it is not. My son had / has allergies. Had to take a shot every week. We pulled the carpet up, got the hardwoods refinished, and soon after. he was able to stop taking his shots.
