everytime I use it? It was only bought in Feb/March this year. Its an upright Hoover (hate it so much! but couldnt afford a replacement Miele) I have checked the bag is not full, the filters are clear, and yet it still makes an awful burning smell. I am wondering if its because I am using paper hoover bags and not the HEPA fabric filter ones. I put washing poweder in my hoover bags as it helps with any pet smells. Could this be the reason?
