I cleaned the inside of my 2011 Nox today. It has not been done in at least 6 months. The Husky liners I purchased for them was well worth their high price. It is the first time I have spent the extra for liners and have always had floor mats in my vehicles. These make it a breeze to clean and very little dirt get by the liners. I had to vacuum a little near the edge closest to the doors but have never spent this little amount of time cleaning the floor/carpet area. I recommend them if anyone has been debating getting them.
