Rust has started to form on the knives just where the blades are fused to the handles - right at the seams. Looks like rust starts from the inside of the handle. Unless design is changed, don't know how replacement knives will be any different. Too bad since knives are sharp and set is designed beautifully. Answer:

I was hoping by going with Hoover again I would get another great product. Boy was I wrong!! The dirt cup on this vacuum needs to be emptied often, at least every time I vacuum and sometimes more. The suction is horrible. Lots of dirt gets left behind. It smells like rubber is burning every time I use it. The cord is way too short so I am constantly changing outlets. I am going back to a bagged vacuum. TRUST ME, DON'T BUY THIS VACUUM!!! Answer:
