Remove 4 screws on top and remove this cover. Belt and roller are easily accessable.

Is there a belt for the Eureka 4388 B-2 Model"

Hello,

Your Eureka Whirlwind model 4489 uses the Eureka Style U belt. There are several different U belts that Eureka makes, including a generic one that's made by Eureka under the Smart Choice name. Eureka also makes a Eureka Style U belt Extended Life, apparently increase the life of your Belt.

Here are links to all of the Eureka U belts that will fit your model:

i have never heard of any belts in a vacuum cleaner

Hi Please visit http://www.eureka.com/parts.jsp and enter 450 into the first box on the page where you put the model number. This will gve you two options, one is for the PDF user manual, the other for parts.
Alternatively if you are trying to get into the drive belt locate four screws, two at the front and two at the back on top of the hood. Once undone, the hood should pop off easily to reveal the brush roll and drive belt. If the belt is intact check that the dust channel is completely free of blockages.
Dont forget to rate thanks!

If you torn the macine over, at the bottom of the sweeper you will see the belt on on side. You have to take the bottom part apart and remove the brushes to replace the belt. I hope this helps.

I no more use Eureka 4331 (Boss Lite). But the most common reason for not picking up dirt might be the vacuum bag might be full. Need to be Clean or replace as recommended by the manufacturer or The air filter traps particles as the air travels through the vacuum cleaner. If the filter is clogged, the vacuum cleaner will not have proper suction. If your vacuum filter is clogged, refer to your owner's manual for cleaning instructions. I recommend having Eureka Power Speed for yourself.

You did not say which brand and model number you have, and they are different. Belts go around the brush roll and the motor shaft on most models.
