I don't remember the exact purchase date, but it was over 6 years ago. I have kept it stored without ever using it. I thought it would be a waste to keep it without using it, so I'm putting it up for sale. The bag and the dust bag are clean and beautiful, but the outer bag (photos 6 and 7), which was stored separately, has yellow discoloration. I think it can be cleaned with bleach, but I will include it if you need it, so please let me know after purchase. Thank you.
