Has anyone tried a different roller that ‘MAY FIT’ and found a compatible one? I have the HV300 26 and have counted on it for years. Had taken it apart several times in the past and cleaned it out. My daughters help out by cutting the hair out with scissors. It’s been done so much that the white casings have completely worn. They’ve been shaved down by scissors and now the roller is loose! I’d love to keep this vacuum if there were any roller brush out there that would fit? Even if I could order those white end caps (haven’t found that either). Any suggestions?
