Car detailing/vacuum options for the garage?

[C2 Turbo]

Looking to get a system where I can vacuum/detail our cars? Wall mounted vs one with may be wheels that can be dragged around, options?

Thanks

I find a canister/shop vac to be the most useful.

A wall mount can be somewhat useful in the since that you don't have to move/push/pull/store the canister. But instead, drag 25' of hose around everywhere!
