vacuum motor burning out??

[Use Less]

My quite-old Eureka mighty mite canister vac started acting up today. It smelled hot-burning rubber sort of smell- & the motor seemed to be revving down. I changed the bag, cleaned the filters and tried again. It seemed to run better, but still smells awful. It won't be worth a trip to a repairperson. Is there more I could do to fix/stretch its life a bit? I'm reasonably handy, but its not worth hours of work to me. Thanks, Sue

Generally rubber smell is belt that drives roller,you will have to unscrew bottom and check.

I'd guess the brush is obstructed and the belt is burning
