Yea I’ve noticed if the vehicle is very dirty with dirt , it is not as effective. You need water rinse and scrub first then use the steamer for extra finishing touches .
Yeah. That’s what we do with the Vapor Rino. It has a extractor hookup. But it really doesn’t do that well on deep cleaning. So we use hot water extraction and then follow that up with the steam extraction with the Vapor Rino.
