My dyson makes funny nosie when iput it on - Dyson Bagless Upright Vacuum DC41 Animal

The usual: take it apart (the easily removed items, dustbin, etc) looks for blockages in the suction path (there are several bends where stuff tends to get stuck. Clever Dyson engineers usually make these sticky spots easy to get to for clearing.

Otherwise, have you ever cleaned the cyclone head? Dyson's (and all centrifugal vacuums) are susceptible to dust clogs because of damp dirt or high humidity. This often build up in the head, unseen, to the point where there isn't enough air flow to maintain suction, regardless of any advertising campaign. Check youtube for videos on "cleaning Dyson vacuums". Some of them are pretty funny.

If none of that helps it might be time to replace the motor (or upgrade) depending on your preferences. Most parts for Dysons are available either direct from Dyson or online through various outlets.

The clutch has belts in it which lose elasticity and should be replaced frequently for proper performance. The brush bar also gets hair and debris that works its way into the bearings and main shaft. Check this area thoroughly and clean or replace as necessary.

Hi there,
Most likely you have a damaged commutator. I used to change the brushes on the dyson vacuums but what i found is that it is almost never completely successful. THe Dyson motor is not as good quality as say a miele and when the brushes go they normally cause damage to the commutator. THe best bet is to replace the motor. If you were able to swap the brushes a motor change will be easy for you. If you are in Australia you can get the motors from VacuumSpot or Nelson Vacuums.

Hi there SmartAlec here. The noise is coming from the clutch, you have either got something caught in the roller or maybe the bearings are siezed in the brush roller. I have made a video to show you how to fix either problem. If the video is helpful please take the time to rate this solution or leave a comment. If you need filters or parts for your Dyson dc07 you can buy online at vacuumspot or nelsonvacuums.

make sure the filters are pushed it all the way and the pipe work is clear

That's the clutch. An extremely hard piece to replace. Your vacuum is pretty much a paper weight.

It might be that the drive belt is stretched, broken or worn. It can cause the brush to not turn and it will make funny noises. I would try changing the belt. You can get a replacement here:

Dyson DC17 Belt

You need to clean your roller and replace the clutch assembly that drives the belts. poorly designed vacuum with many flaws.
