Best cleaner for cloth seat interior and carpets

[996ttalot]

What would you recommend for our garage - we have a number of cars coming in where te seats are cloth and are showing signs of general stains etc. also to be used for carpets and headlining.

Would want to be able to turn the car around as part of other work so don't want the seats damp etc afterwards for too long.

Have seen the normal vet n vac and also steam cleaners. What solutions do you need to use etc.

Budget up to £500 or so
