Eureka 2991AVZ Bagless Upright Cyclonic Vacuum\015 I have a Eureka Boss 4D pet Fresh vacuum. It worked great but now when I use it I get a harsh burning rubber smell, and the side of the vaccuum feels like it’s going to catch fire. It still has suction….but I can only use it for 2 minutes at a time before the smell is back.\015

How to Identify and Fix Common Vacuum Problems ?

Our sources include academic articles, blog posts, and personal essays from experienced Vacuum Technicians :

If you`re smelling rubber, the belt has either burned out and snapped or the belt has become so stretched out that the roller is not moving and the vacuum belt is getting super heated from the motors RPM.
Overheating due to clogged exhaust filter

The exhaust filter can also get clogged, causing a problem with the motor cooling. Therefore, you should also check the exhaust filter if the vacuum cleaner smells burnt. It is usually located on the top or back of the unit, right where the exhaust air comes out.

According to Lorna Smith from robot vacuum cleaner retailer Eufy Clean, a smell coming from even a bagless vacuum cleaner is usually generated from the reproduction of fermentation bacteria, and is closely linked to your habits and how you use it.
There are four primary culprits of vacuum cleaner odors. They are pet hair, mold, a burned belt, and too much dirt, Oh So Spotless reports. Pet hair, dander, and any attached urine all smell outside the vacuum and continue to smell once inside.
A plastic burning smell in house situation can occur from a number of sources. Faulty wiring or an overheated appliance can have an odor that smells like burning plastic. If it`s coming from your HVAC system, it could be from an overheated blower motor — possibly due to heavy dust buildup or a clogged air filter.
A strong odor from the shellac that coats the copper coil windings is an indicator that the motor is about to or has burnt out. If the motor is still running, even if it turns on and off by itself as it is heating and cooling, you can still run the motor until it gives up for good.
As the cleaner head and filter fills with dirt and debris over time, all the built-up debris begins to emit a burnt-smelling odour. You may need to remove and clean out the vacuum`s filter. We need to advise you to stop using your machine and request that you contact your local customer support team.
Bagless Vacuums are Not Hygienic and Diminish Filtration, Suction and Cleaning Performance – Without bags to hold nearly all the captured dirt, the microfilters on bagless vacuums quickly clog from excessive dirt build-up and must be replaced often or a loss of suction and cleaning effectiveness will occur.
For bagless vacuum cleaners: Remove and clean the dust bin/canister. If possible, wash it in warm water. You may be able to remove and wash the hose, wand and accessory heads too, if they`re very dirty.
Even though vacuum cleaners are great for removing dirt and dust from your home, it is necessary to maintain them properly to keep them doing an efficient cleaning job. Dirt accumulates over time, and if not removed regularly, it results in an unpleasant odour coming from your cleaner while you are using it.
A clogged air filter can`t leave anything clean and will eventually break down from the inside causing the vacuum to first smell, and eventually not suck well causing it to break.
If you can smell burning, particularly if you don`t know what`s causing it, it`s vital you dial 999 immediately. Just because you can see it, doesn`t mean it won`t get out of control. Even if for some reason you don`t feel like it`s an emergency or not worth our time, trust us, it is!
If you have phantosmia, the odors can vary from smells that almost make you sick to really pleasant scents. But most people with phantosmia tend to detect bad smells. The odors have been described as “burned,” “foul,” “rotten,” “sewage,” or “chemical.” You may be smelling it from one or both of your nostrils.
When a thermal cut off activates, it shuts the motor down. This prevents the motor from overheating to a point where it will no longer function and will need replacing.
According to the U.S. Consumer Product Safety Commission, certain models of the Bissell Multi-Surface Wet Dry Vacuum are being recalled because the battery pack can overheat, start smoking, and poses a fire hazard.
In many cases, the smoke you see is actually mechanical pump oil vapor. Many people tend to think that whenever there is smoke emitting from the pump, it means there is something wrong with the machine. But, oil vapor or oil mist is a natural by-product of creating vacuum in an oil sealed mechanical pump.
Vacuum cleaners are often designed to turn themselves off if they hit a thermal cut-off point. Basically, if the machine is starting to overheat, there is an automatic system in place to prevent damage to your vacuum or other issues. The most common cause of overheating is blockage.
A damp or musty smell is caused when dust in the cyclone has come into contact with water. It may not be a direct contact with water, for example when vacuuming pet hair that is slightly damp, this moisture will combine with the dust in the cyclone causing the smell.
This usually happens because the filters need washing or your machine is blocked. If your machine continues to overheat, please refrain from using it until it has cooled down sufficiently and then carry out the performance checks.
Bagless Vacuum Cleaners

No need to worry about keeping bags on hand or where to find more. There is no extra expense for buying bags. If your bagless vacuum has a clear cylinder or tray, it`s cool to actually see all of the dust and dirt particles swirling around in the dust cylinder under high pressure.

Bagless vacuums can save you money because you don`t have to buy replacement bags. But like bagged vacuums, they have filters that need periodic cleaning or—for HEPA filters—replacing, probably more often than with a bagged vacuum.
Place the removed vacuum parts in a sink or tub filled with warm, soapy water. Soak and rinse everything well with hot water. Use a faucet sprayer to quickly remove tough dirt and sticky residue. If needed, scrub with a sponge or microfiber cloth.
Don`t be tempted to reuse vacuum cleaner bags. Your motives may be pure, but your air won`t be, and your vacuum cleaner may bite the dust (pun intended) years before its time.

The original belt on my upright Kenmore Progressive broke and I replaced it with the spare that was in the vacuum. The vacuum and spare belt are about 10 years old. Then the spare broke after one vacuuming session and there was a burning smell coming from the vacuum. I ordered new belts and replaced it with the new belt. It seems to be working fine with no smell. I checked the belt after I vacuumed the family room and although it was in tact, the belt was very hot. Is that normal? Should t
ANSWER : The belt heats up due to the friction, as well as being in contact with the shaft of a hot motor. It is normal.

I purchased a brand new Eureka Pet vacuum, sorry don’t know exact name but it the one that has the self cleaning duster on it. Last night I used the vacuum on my carpet, it was working fine until I accidently sucked up the corner of a scarf that was hanging off a couch. I shut the vacuum off, pulled out the scarf and and resumed vacuuming. Much to my dismay the suction on the vacuum had ceased. Can you tell me if there is a reset button on the vacuum? The vacuum does not appear to be damage
ANSWER : If the motor is running, there should be suction. Possible problems depend on whether it’s a canister or upright and are:
.A clog in the hose, UR or canister. Detach hose. Drop small coin in one end and lift hose causing it to roll out the other. If it does, no clog in hose. Drop same coin into hose opening on power head. If it rolls out, no clog in PN.
.Broken fan blades, UR. Needs to be taken to shop for repair/replacement.
.
.A reset button is for use if the motor isn’t running, so won’t have anything to do with the suction.

Burning Smell Hi, I have a Rainbow E series that when I run the vacuum there is a burning smell. I have cleaned the entire unit and filter but still have the smell? I am afraid that the motor will burn out?
ANSWER : Check the carbon motor brushes, there might be arcing on the armature. New brushes may help if the armature is ok.

Dirt devil vacuum cleaner–trouble vacuuming dirt and pet hair on carpeting –is the problem with the spinning brush which contacts the floor,  not contacting the carpeting??  I thought (when I bought this vacuum) that the aforementioned brush was adjustable to various heights of carpeting.  Sometimes, it seems like nothing is being vacuumed up –unless I have just put a new bag on the vacuum… Do I need or can I replace the spinning brush on the bottom of the vacuum so it kicks up and vacuums
ANSWER : Try replacing the belt. Rubber belts stretch out after about a year.

Burning Smell coming from the moter
ANSWER : 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.

Bissell lift off pet revolution vacuum smells bad when I vacuum!
ANSWER : Put a BOUNCE sheet inside the filter

Vacuum smells I have a 6 year old rainbow vacuum model E and it smells terrible everytime I use it. Probably because often times i don’t remove the water basin after vacuuming and just let it sit. It’s my own fault however now I don’t know what to do to get rid of this terrible smell. I’ve water cleaned the hepa filter, not able to remove the separator screw to clean. Can you give me some suggestions?
ANSWER : In addition to vinegar, baking soda (sodium bicarbonate) is also an excellent remedy for many odour problems.

Try generously sprinkling baking soda on a rug you wish to clean, and afterwards, vacuum up the spot.

Rugs, and dirt may be broomed beforehand, and you may want to spread the soda over a large enough area to avoid having a small “clean spot”.

Repeat as necessary, and buy the bigger boxes of baking/washing soda. It has many more great uses that you can discover.

Vorwerk ET 340 – been great but now noticing strong burning smell after vacuuming some hair from the bathroom. Bag is nearly empty. Gave it a rest then unscrewed the cover housing the motor and all looks clean (dust is sucked up the pipe and doesn’t appear to get near the motor). When I restarted it, burning smell still there. Are there any filters that might need changing? What could be causing the smell? Could the hair have gotten caught somewhere? Thanks.
ANSWER : Jessica,.
.Try changing the dirt bag..Check if the motor gets hot after operation. You can come to check it by touching outside the motor housing. If it is hot or just warm..Is the smell of burning hair or something else? May be rubber or plastic???.Please check and confirm.
