Last time I used my Bissell Pet Hair Remover vacuum it smelled like something was burning and it left a black mark on the carpet. What should I do?

roller brush jammed yp with lint , cords and rubbish
clean and replace the belt
take it to a vacuum repair shop

If the burning smell was like rubber burning it is probably the belt. If you only used it a few times I suggest bringing it back to place of purchase. A belt should not go after just a few times of use. Besides if anything is burning after just a few uses I would return it.

Don't have a solution to the whole odor problem. But my machine smells musty or moldy so I have taken the dirty solution tank and turned it upside down and shook it filled with detergent. You can see the white pipe, or that's what I call it open so additional water drains out. But a bigger problem with my machine occured about 3 weeks ago. I was using my machine and when I picked it up off the carpet there was a black liquid that had come from the bottom of the machine. Which is not good given I have white carpet. I contacted the Bissell Company and they had me send the machine to them and they provided a prepaid shipping label. Also the company send me a bottle of pet and stain remover to get the stain out. As of yet the stain has not been totally removed. A bit of advice so this doesn't happen to you is to put a towel under the machine when using. I say this because I'm not sure if it is connected to the bad smell and thinking it might be a black moldy liquid. Hope this helps.

We had the same problem, and it turned out that the roller wheel height setting had broken, for no apparent reason, and was "floppy" so we had to lock it in to one setting with epoxy.

Limits utility, but it works. Sort of.

it sounds like something is backwards. the brush should only rotate when using it on carpet, it should never rotate on the bare floors. check the belt for propper installation

the brush is always turning on the machine even when your using the tools. try not to set it down on thick carpet , or if you can set it on the linoleum.

If you have followed the instructions.And your not happy i would return it.Get a repacement.

The burning smell is caused by the heat generated from friction. Belts stretch and thus are worn out and must be replaced. When you do it (it is very easy) you have to remove the roller brush completely, anyway, clean it at the ends of the shaft of any pet hair and/or carpet threads. Also clean the area in the housing where the shafts rest. This will keep it rotating smoothly and your cleaner will operate more efficiently.

put a BOUNCE sheet inside the filter

Does it smell like anythings burning if it's on for a while?

It could be that the belt is just stretched out and not keeping enough tension on the brush while its on the carpet. Once you tilt the vacuum up, there's no more friction, so it spins freely. I've had a few that did that.
