Do you own a vacuum to clean the inside of your car out?

I just got some minor body work done on my car and before I had that done, I cleaned the car out. It needs a major detailing inside. I need to do a good vacuuming, wiping the dashboard, etc.

Do you own a vacuum for the inside of your car or do you use one at a car wash, or do you have people do it for you?

I am considering buying a vacuum for the inside of the car (as part of my renewed effort to keep my car clean LOL).
