We have a Giant Vac model 956. The unit is one year old and it is still sold new by Giant Vac. So I called 3 dealers and all of them said that the bag is not available anymore and their is NO replacement, I tried calling Giant Vac and 3 "tech" agents said the same thing, not available, sorry. We use the machine for getting around houses and tight spots and it works well, but not without a bag. Anyone have any ideas?
