I sold those
I sold those Dirt Hunter Sanyos in my vacuum shop. 1999 to 2002. My sister-in-law bought one and used it till 2008 and replaced it with a lower end Dyson. I was not really impressed with them, being I'm a Kirby and Lux man. They did not sell very well, but then again my shop didn't do that well either. The Sanyo bagged models that were Panasonic Jet-Flo clones were much better. I think I had two left at the time my shop closed down. I think I sold them on ebay the next year.
If it cleans well, keep it. If not, donate it to a charity thrift store if you have one near by.
