Question about Eureka Vacuums
My Eureka upright model 4703 that I have owned for over 3 years started to smoke today. The smoke was coming out of the belt area where the belt connects with he motor. I opened it up and cleaned out the brush and belt area, tried it out again, but it still started to smoke after about a minute of use. My guess is that it's coming from the motor shaft slipping under the belt, causing the belt to burn. The belt doesn't look too worn. Would replacing the belt fix this issue? Or is it time for a new vacuum?

SOURCE: smoking belt
Belt is slipping because the bearings on the beater brushes, which it turns, are jammed or full of dust.
Alternatively the belt has stretched after being overheated and needs replacing because it now slips.

belt doesnt have to be broken, check the metal arm on the vacuum, see if there is build up of old rubber from previous belts, clean the arm that spins the belt and double check to make sure u have the correct belt

SOURCE: Burning smell and smoke
I ran into a scenario similar to this at work. With the burning smell and smoke combined, it leaves only one problem remaining; the motor. The motor and the pulley that enables the belt to spin could be malfunctioning (causing friction between the 2 parts) and thus causes the burning smell and the smoke. I'd highly advise not to touch either part after having the unit on (YOU WILL BURN YOURSELF).
The only other likely possibility is to make sure there aren't any hairs caught in or around the motor and the bearings of the agitator.

SOURCE: Vacuum motor shaft too hot
Check the brush roll ends, will they turn easily or is one frozen. If so, you need to replace the brush roll. If the motor turns on, it and the belt are trying to turn the brush roll and can't. Also check the ends where the brush roll sits in and make sure it hasn't overheated and melted., If it did you will have to replave the base.

Make sure everything is dried off, I encountered the same symptoms once when I had some water remaining in the rotating brush after wiping the machine down.
