Your machine is a little different from my red one. mine has a stretch hose nearly the same as the world vac, and I believe it had the same method of attaching to the machine. But, yours looks like it takes the much longer regular plastic hose found on the somewhat-rare 7800 series (i.e., the world vac bravo II, special edition bravo II; machines with the hose-to-floor switch on the base). But if it shares the exact same base as my VIP, then it would be plausable it takes the world vac hose end.
Easiest way to tell is I believe the world vac's hose end was flat, whereas the 7800's had a curve to them. So see what your machine has.
Both hoses are still available, can't site any sources but I know they're still avail.
OR, as I just had a revelation now, I only made that assumption about you having a different hose from seeing the hose hook on the handle, but maybe it's possible the handle was replaced with a bravo one, and your machine does use the world vac's stretch??
