Ian, I have to phone the US later today so I will try and find out about the rotovac, I havent a clue as I dont ever use one, nor would do.....Gary, I will get some names of some machines for you but there are quite a few......The Ninja isnt that well thought of over there although I have heard good things said about them over here......... Bridge Point, Steamway, Steam Genie are a few suppliers that might have web sites to look through..... Steamways isnt the best of sites but does show and go through all you need to see.... and you can see my truck mount too..... best, Dave.
