its a Butler upholstery tool with internal bypass adjustment.
any photo i post can be used by anyone, i never really care.
this a Buffalo fabric which I find the easiest clean of all fabrics but it does water mark really easily if you do spot removal.
this was a 5 seater corner unit with another stain the same size on the other end, took me an hour to clean with like you can see really good results..... pity it was still damp when i left as it tends to dry really slowly
