This Machine was made by Steam Services,, Ed York. Its called the Pro, Electric unit that had a #2 blower and a 3 stage vac I think. The Drag tool weighed #65 pounds. And had to pull it as you were backing up,pulling the handle up and so the weight was over the vacuum head. then push down on the handle and move forward. then lift up and pull back spraying the jets and pulling back. I had 1 for years, the only drag was carying the Dam heavy drag wand. Great for extracting water from carpet though. The price at that time was around $4,000 for this stainless steel unit. postaldave.
