Question about Eureka The Boss SmartVac Upright Vacuum Cleaner 4870MZ
When upright, the brushroll spins fine. As soon as I start to vacuum carpet, the brushroll stops as the friction with the carpet increases. I have installed a new belt so that doesn't appear to be the problem.
Hi, it's Cindy from Crucial Vacuum.
Since you have replaced your Eureka 4870MZ 9200 Proheat 2x vacuum's belt, the issue may either be caused by your roller or the position of your belt. It sounds like as soon as your vacuum is lowered, the belt is either slipping or wear on the end caps is causing your roller to stop. This will cause the burning smell since your motor is now straining against the abrupt stop. Try taking off your roller and checking the conditions of the end cap or try to reinstall your belt. I have included an instructional video: http://youtu.be/rji0fl9hytY

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.

I tried the electrical-tape-around-the-wooden-spindle technique. After a minute or so, it's back to functioning normally.

if the belt has been slipping it may have pollished the moteror brush shaft and it just slips. take a small piece of sand paper or enery cloth and ruffen up the shaft to give it some grip.
if the metal shaft of the motor has been heated up due to slippage it will take some doing to ruffun it as the shaft will be hardend due to heat
