How do you clean the carpet in your RV?

We have had the Alfa for a little more than two years. When we bought her the carpets were pretty clean. Ugly, but clean. On two of our service stops at Alfateers, the carpets were done as part of their regular customer service. When we were there last time, the machine was not working.

So, by now the carpets were really in need of attention. At the house, we have either had a rug cleaning company come in, or rented one of the machines and shampooed the house carpets ourselves. I thought about that, but the Rug Doctor machines are so big I didn't think one would fit easily in the RV. I guess they have hand tools and upholstery attachments, but getting the basic machine in seemed difficult.

Since my daughter has two boys and a golden retriever, and light carpets, she also has a nice Hoover rug cleaning machine with a long hose hand-tool attachment. We used it Tuesday on the Alfa's rugs. I thought it would be a quick and easy task.  NOT! Craig did all the hard work because I have a "touchy" back. Bending and crawling around on the floor is just not something I can do without hurting for days after. So, I don't do that part, but I did help with the vacuuming and moving the machine from place to place.

Craig did a pretty good job and because we are sleeping at her house while they are gone, there is plenty of time to let it dry. Today while the boys are in school we will go over to the RV park and put things back in order. The Alfa looks like it has been picked up and turned over right now.

My question for other RV owners is "how do you clean your carpets?" Will the truck based carpet cleaners come to an RV park and do it for a reasonable amount? I know you can have a car detailed. Is there such a thing as an RV wash that will also do the rugs?

We (or should I say Craig) can do it, but I would like to hear about our options.

Of course, we are penny pinchers, so,  whatever the options are, we will probably keep doing it ourselves. We take our shoes off about 80% of the time, but during set up and tear down it just isn't practical. It also seems that any little smudge attracts black dust. We have had the exhaust system checked and we don't have any leaks, but diesel dust still seems to seep in and settle on everything.
When I run a cloth along the edges of hard surfaces like the window frames, my cloth picks it up.

Does anyone else notice this?
