I wouldn't hit any part of your car inside or out with that much pressure. I use a carpet shampooer on my floor mats, and interior carpeting. I use about 1/4 or an 1/8 of the amount of shop you'd normally use, so it's mostly a water wash.
And get a good old sponge or rag to wash your car, a little TLC is way better than a power tool.
