Generic problem for all Vacuums
I replaced the belt on
Posted by piggytail on May 01, 2008
I replaced the belt on my Dirt Devil Featherlite Bagless Vacuum and the brush roller rubs and makes a very loud noise when turned on. I have gone exactly by the manual instructions and made sure the belt and end caps were on correctly, but the bristles still rub the back and it makes a very loud noise. Without the brush roller in the vacuum, it sounds and runs normal. What could the problem be?

Hello,
I would advise you to ALWAYS to FIRST UNPLUG YOUR VACUUM before beginning any service procedure.
The Royal Dirt Devil Featherlite Bagless Vacuum has just bushings in the ends of the brushroll and not bearings and once the bushings are bad I suggest that you replace the brushroll in the vacuum and put a new belt on the vacuum as well. There is no way to repair the bushing s in order to it to work properly. The suggested belt change is every 4 to 6 months and to store the extra belts in a Ziploc bag in the refrigerator to keep them fresh. Suggest looking at a local vac dealer. So if you need further assistance, please feel free to contact your local vacuum cleaner dealer in your area or in the yellow pages, or contact the factory phone number or website to further assist you with your questions.

SOURCE: ratchet noise, beater will not turn, belt not

Ok, so I had the same ratching noise and took the advice of many sites directing me to clean the brush. But like most I cleaned the brush and the noise continues and the brush does not spin. Reluctant to take it to get serviced I dug a little deeper and now it works just fine. This is what you need to do as removing any hair from just the brush part will not be enough.
Remove the entire brush bar from the bottom of the Dyson, this means pulling the bar out of the drive belt. This is not to difficult just use a little muscle as the belt will stretch. Once the bar is out grasp hold of the two plastic end caps on the brush bar which the brush bar actual spins in. These two caps are connected by a slim metal rod which runs through the brush bar. Place one hand on each side and begin to twist and pull until one of the caps comes off. Once the cap is off of the one side you can pull the other cap from the other side through the brush bar as this cap will be the one attached to the slim bar I mentioned above. If like mine you will see a ton of hair wrapped around these caps and inside the ends of the brush bar. Clean them out as best as possible.
After you clean it out, run the cap with the rod back through the brush bar, attach the other cap and twist and push together. Make sure the caps lineup which each other just like they were when you pulled it out. You'll notice how much more freely the brush bar spins between the two caps then before you cleaned it. Now, pull on the drive belt and feed the brush bar back through and attach as it was to begin with. This did the trick for me.

Sounds like you either have a very clean floor, and only dust remains OR, you have dust and baby powder on the floor clogging the hepa filter. THIS time wash the filter with water, then check for blockage in your waste gate area.
