I think it was a really good investment. The vacuum cleaner was with a friend who no longer uses it. It appeared to be in perfect condition until I noticed the brush and belt were worn out. I have decided to replace it for $30, the most that can happen is that it doesn't work and I will invest in a new commercial vacuum for myself. It appears that Sanitaire's "brand name" is nowhere on this product. However, it fits perfectly and works just as well. Would recommend and buy again if needed.
