I don't know how much help this is - I have tile and I don't know what a HAHN steamer is, but I have a Shark Steam Mop that I LOVE. It is a little different and takes some getting used to but it is great. Over time it got up tar that my husband tracked in. I had tried EVERYTHING to get it up and finally gave up. After a couple weeks using the mop I noticed the stain was gone. Good luck!
