Re: Steamer as sole detailing tool?
I don't think I could ever see myself 'washing' an entire car with steam
But I use steam on nearly all my interior details. Exterior mainly for removing someone else's wax from the cracks / emblems
and as you've discovered, a high quality commercial continous fill steam cleaner is buck$$$
you can get cheapies for $100 range (that work ok), better stuff in the $300 range (steam is a little more dry, usually more attachments), the vx5000 is around $800 (used to be $700) and over $1000 you typically start seeing the commercial grade machines with continous fill
