I bought this to lay outside our pop up camper door. The rule is, you take your shoes off on the ground at the edge of the mat, then walk over it barefoot to enter the camper. It keeps the camper carpet nice and dirt free, and if the rules are followed, the mat stays clean, too. By the end of the weekend, there is always some dirt on it, but it is easy to hose off. I love how it folds up nice and small. Although I have trouble getting it to fold up so I can use the handles, but that doesn't really matter. I just stick it in the camper until next time anyway. I'm going to buy another one to give us even more clean space outside the camper. So far it has held together very well.
