Is it wise to use a vax machine to clean the carpets of my 2004 Bailey Senator? I use the van for working away as well as holidays and the campsite I'm on gets quite muddy in the winter. I always remove my shoes on a mat by the door but working 12 hrs a day means the van can get a little messy. I would only use one on a hot day, when there's a good chance of it drying quickly. Thanks for your help!
