Hi Greg,
This dry power nozzle came along later in the early 90s, when they added a disposable bag to these cleaners. I think any shop vac liner should fit. This light gray/blue and then a white/green which matched the final white/green Cleanmore that was discontinued after 1995 when the turtle shaped cleaners replaced them in '96.
My machine just has a cloth filter, but I plan to make a covering for it with a HEPA bag, since there is no way to fit a bag on these 80s models.
I don't have the Spraymate attachment, but I'd like to get one in the matching colors. All I have is the floor cleaning tool, but I'd like the upholstery tool as well as the squeegee and other vacuuming attachments. But any 1-1/4" tools will fit.
