I had one of those. I just can't remember what its called....
.....and that of course is a really helpful answer
I seem to recall it was quite a good machine with plenty of suction but was a really really heavy machine.. It was awkward as well as it had to be completely empty to put in the van because you roll it into the van on its back.
I inherited the machine first day of buying my business hence why I can't recall the manufacturers name.
