Re: odor of burt rubber

Take the brushroller out and hold both ends without touching the wooden part. Spin the brushroll. If it doesn't keep spinning on it's own after you let go, the bearings are shot and you need a new brushroll. Go here for more helpful links...

I have a vax bagless upright mach 5 no power at all

usually...burt rubber smells indicate burning rubber.... the belt will get hot and smell like this if the brush rollers are hard to turn due to hair or string getting caught in the roller and especially at the ends of the roller where the axle of the roller meets the vacuume cleaner .... ya gotta take the whole brush off and clean it... if you use it on damp floors ( like carpet where snow was tracked in) the metal parts can rust and cause it to bind. if the vac no longer turns on at all.... you probably blew an internal fuze (if it has one) or burnt out the wiring..... fuzes are replaceable but wires require a vacuume cleaner repair person.

Burnt rubber smell when vacuuming

This could be a few things:

A. If your model has a floor selector switch (Bare floor/tools - Carpet) your clutch could be worn. (there is a rubber clutch pad between your cam and roller shell) - Fix would be to replace the clutch pad and belt.

B. If you don't have one of the above models, your belt could be stretched. The belt slipping could cause a rubber burning smell. Fix - Change belt.

C. Have you got any new carpet you are vacuuming or have you moved? Some of the newer style frieze carpets can cause burning rubber smell. The fibers of the carpet are longer and cause the brush to slow down causing the belt to burn. (Imagine brushing long hair with a thick brush, the hair easily gets tangled in the brush, same effect with this carpet.) Some of the newer rugs can do this as well. Some newer carpets with the thicker felt backing and/or the "pet padding" under the carpet can too. it doesn't allow enough air to flow through causing the cleaner head to seal itself to the carpet causing a burning smell. The fix is Move to another home, replace your carpets or replace your vacuum. The vacuum is the cheaper option but be cautious as most vacuums now do this with these carpets. We have had really good response from customers using the Simplicity Tandem Air models, (Synchrony and Synergy models.)

Hope this helps, if you need to talk further feel free to contact me.

Vacuim sweeper motor has a high pitch squeal otherwise runs fine

If you can notice a smell of burned rubber near the sweeper, then you most likely have a slightly stretched belt. The belt would be spinning against the beater brush, causing the squeaking noise -- as it heats up, the belt will begin to smoke, or at least give off the smell of burned rubber. This will be the most noticeable if you use the vacuum for a few minutes and then turn it off -- most times the suction from the vacuum will pull the smell into the vacuum and keep you from noticing it until it has been going on for quite some time. Replacing the belt should fix the problem.
Before going out and buying the belt, you might want to check between the belt and the beater brush -- if there is a lot of debris between the belt and the beater brush, it will cause the same type of slipping as a stretched belt, and could also be the cause of your problem. Either way, to fix the issue, you have to open the bottom of the vacuum and take a look at the belt -- if it looks to be in good shape, move it around a little. If it has a lot of room to move, it's probably stretched. If you notice a big hair clog under the belt, this is most likely to be your problem -- clean that out and you should be good to go.

Kirby upright smells like a foot. Changed the bags. We had to move it to the garage for storage beacuse it made the closet smell like bad shoes. Gets strong when used

Check the brush for accumulated hair, and other debris. If the brush is belt driven check the condition of the belt, over time the rubber deteriorates and melts when heated up during use creating a burning rubber odor.

When its in use there is a burning odor

If it is a rubber smell, the belt is slipping and should be repalced. If the smell is a sharp electrical burning odor, the motor brushes are sparking and the motor may be damaged.

Every so often I get a smell of burning from my g4 Kirby vacuum. I noticed it's when I'm vacuuming a fairly new rug on this house I clean. Should I be concerned?

If it is a smell of burning rubber - most likely your vacuum belt is overdue for replacement.

At this point - remove the brush roller, remove the old belt, clean off your brush roller and remove any string or hair that may be bound up around it (usually around where the belt goes or on the sides), and put on a new belt. Your Kirby should act good as new if your bag is replaced at the same time.

If the brush roller has too much string and hair wrapped around it, many times the brush roller will not spin as fast as the belt is driving it and you will get that burning smell.

Makes a loud noise like a grinding noise then smokes comes out and it smells like burning rubber? When I take the (rod) brush off with the belt then run the vacuum there is no more noise? Please help me...

Your belt is worn and stretched and so it is slipping on the motor drive shaft. That is why it is noisy and smells like burning rubber. You simply need to replace the belt. You can get replacement belts here:

Burning Smell coming from the moter

This could be a motor problem. There is always a slight blue arcing that occurs when an electrical motor runs and can be visible through the exhaust vent, but any excessive arcing indicates a problem. If the carbon brushes are sticking, this will cause excessive arcing and can be corrected by an experience service person, but if there is any electrical failure, the motor would have to be replaced. There are no parts available for these motors and the expense of replacing an armature (the likely culprit) would be more than the motor. This could also be as simple as a worn belt, but usually, belts will not produce the smell your describing. When a motor is burning out, it will produce an acrid odor that will linger for a long time.

Burning smell

Hi. What does the burning smell of? Is it 'rubbery', or is it acrid and 'chemically'?! The most common item to 'burn' is the belt which drives the rotating brush at the front. Does your cleaner have a belt? This would give a burning rubber smell. The instructions should explain how to change the belt - have a close look and see if the belt has been slipping on the motor spindle. If it has, then it'll probably be worn at this point and should be replaced. A common cause of this happening is the brush bar getting caught in something - edge or rug, etc - and being forced to a standstill. If the smell is more 'acrid', it could be a problem with the motor. This is a repair service job.
