Vacuum Cleaners Discussions

When shutting down my Dyson DC24 Ball mini theres a tiny squeak noise exhibited from the motor as it is about to stop.  The shutting down sound is quite rough, but it has never sounded smooth like some other makes of vacuum cleaner I have used.

Is there a problem with the bearings?  I think that there was a noise similar on a Dyson DC05 cyliner that I had.  I used to hear an odd noise on a Dyson DC03 but I thought it was the clutch on that machine.

This machine is pretty loud for such a tiny small wattage machine but I am happy with it overall. Any ideas on the squeak sound?  Thanks.

I didnt post in my orginal post at the beginning that the machine was making a squeaky type on start up as well. The machine is turned on and then 4 seconds after this sqeaking sound was happening for only around 8 seconds, then it disappeared. I thought it was the motor arcing but now I think it was linked to a bearing or something.  I have to say that Dysons are not good at supressing motor noise.
