Minuteman ambassador jr. shampoo extractor

roro, There are two possibilites: One is that each hose does something different (suck and exhaust) or both suck. Find the one that sucks. That should be the one that you hook tools to now. If the attachment has an electrical connection, it will be needed to do scrubbing. If the shampoo unit is from a different brand, you'll have to make up something to do that. If you do, be certain that the connection is fully taped up so no liquid can get to it!!
