I use the VX5000, I use 1Z Deep plastic cleaner as a pre-treat on the doors and other areas that need it. On the carpet, I pre-treat with Megs APC Diluted 10:1, let it soak in and then I take the wand with the big triangle brush and a white terry towel and go over the carpet with the steam, switching out towels as necessary. I usually go back with the vac after that to fluff the carpet.
On the doors, dash and wheel, I use the wand by itself, and a microfiber towel to wipe any excess moisture.
I love mine.
