I have an air mover and think it's a really good investment. I live up in MN so the carpets NEED to be dry in the winter before going outside. The air mover really helps. I'll usually only use it on larger vehicles(vans, suv's) but have used on some smaller cars as well. On a van I'll leave the back and side doors open to keep the air circulating and not so humid. But still on occaison, when a customer needs a vehicle sooner I'll run the floot heat and close it up a little to dry quicker. Hope this helps
