Last month I had ordered 2 ShakeOut bags, 1 for this and the other as a spare, from commercialvacuums.com for around $9.88 each plus shipping, grand total was $25 . I had to clean everything and the Quick Kleen chamber couldn't be polished, Oh well. I had cleaned the fan, calibrated the brushes. As of right now, I'm in the market for a Sanitaire Sc684F hood.
