Burning smell when i vacuum.

pets in house? check all hose passages for "hairball" clog...and check the drivebelt that spins the brush...(some have an electric motor to spin the brush, thus no belt)

If you smell something burning unplug until problem is found and fixed, suspect if no suction hose is blocked and if brush wheel it or the belt may be causing the smell, a bad or failing motor is less likely but possible.

rollers are probably stuck the belt is burning check for restrictions in you hoses as well as in the vacuum as well if nothing else works a repairman

Change all 4 of the filters, and wash the dirt container with soap, water and a little bleach. The only other thing that would cause a bad smell would be the actual motor, but that would be more of a burning smell. Good luck!

Take the front off the vacuum and check inside both the front portion and the canister for additonal clogs. Sometimes something will get caught in the impellor, causing the motor to overheat. Since there's little suction and the smell, I'd guess this is what happened.

Sounds like your belt can either be rubbing against something or its stretched out. Either way you should check into getting the belt changed.

I have the same vacuum. The burning smell is letting you know that your belt is either broken or about to break. I have had mine for a year and have had to replace the belt 5 times. Now I have to replace the brush roller 'cause it broke under normal use. My next vacuum will be a Dyson Ball.

the motor inside is going bad.

About once a month as I have German Shep dogs and cuz of the hair I check all the hoses to make sure they are free of dust bunnies. I also take the bottom plate off the roller, turn the lever to losen the belt and take the roller off. Clean/cut all the strings, hair etc off the roller , check the belt for cracks and burns and replace if need be. Put the roller cover back on, and reconnect the belt.

Then on the side of the machine where the bag attaches, this also slides out to clean. Sometimes heavier items will get stuck in there so that dog hair and larger items cannot pass to the bag and it clogs. This will make your suction very low.

Also a good check inside the bag compartment and clean with the attachment hose if need be, helps a great deal with ordor and dust when turned on. Especially if you have dogs/dander and hair. Ive also put carpet fresh inside my bag to keep the doggy ordor down.

If by "suction" you mean it's not picking up dirt and debris on carpet, odds are your belt needs replacement, and the belt has burned, causing the burning smell. Ensure that your brushroll spins free, and replace the belt. (Belts should be replaced in any vacuum with a rubber belt every 3-6 months, regardless of use.)

If you mean that you are not having any airflow at the end of the hose, you most likely have a clog in the main hose and the burning smell is caused by your motor overheating. Ensure that there is nothing blocking the hoses.

If you have suction in the hose, and your brushroll is turning, there may be a clog in the head area behind the brushroll. Look in the hose that your wand plugs into, and ensure that it is also clear.
