I have had a Dyson DC14 Animal vacuum for about six years now. Recently, it has begun making a terrible rattling noise from the brush head area. The noise is only present when the brush is rotating and occurs regardless of using it on carpet or hard flooring. I have taken things apart several times, seen no obvious problems and reassembled it. I have Googled this and seen it is a common problem. I have done the online recommended fixes: I bought a new brushroll (did not solve the problem), made sure there are no loose parts, hair clogs or blockages (did not solve the problem), replaced the belt (did not solve the problem) removed the endcaps from the brushroll and sprayed with it Teflon lube (did not solve the problem).
Does anyone have this problem or know of a solution? I really like the Dyson vacuum but this noise is driving me nuts.
