The mats came with my 2021. I have had CJ/TJ's for over 40 years and only hosed them out after I had painted inside the tube with a liner of some sort. I can't see dragging a hose into a vehicle with carpet just to spray out the mats. I always take the mat out of my vehicles and then spray them off. I happen to run a Car Wash company so I have the luxury of unlimited free washes. We have automatic mat washers. I ran the OEM mat through (even with the plug sticking out) and it was more flexible and fit through the machine. The weathertec mats in my wife's grand cherokee will not fit through the machine. Yesterday I cut out the plug portion that sticks out below the mat and did the two plug fix described on another thread. Works great and should fly right through an automatic mat washer.
