Brush will not spin

Your answer is yes the brush should be spinning at all times if it's not spinning then you probably need a new vacuum belt

Lubricate each end of the roller brush with motor oil. Bearings inside the roller brush need lubrication for the brush to turn easily. Remove any pieces of thread that have wrapped around the roller brush. If it does not spin after doing the above steps, then either the belt is slipping or the bearings are severely damaged in the roller brush. Then you need either a smaller belt or a new roller brush.

Remove brush bar cover...is the belt broken, cut or stretched to the point of being ineffective? Is the brush bar full of hair or string?
Pull the belt forward...does the pulley spin? Turn the cleaner on
and see if the pulley spins...if it does I think a new belt will be needed.
Be sure to buy the right one.

The belt is rubbing the foot plate.Check to see if the foot plate is damaged.Allso check the bearings in the brush bar are free and spin without the belt on.If you cant spin the brush bar by hand with the belt not attached then your bearings are seized.Get a new brush bar

HI There,

Usually when the belt breaks immediately, this indicates that your roller brush has gone bad and needs to be replaced. I have never seen the motor shaft being damaged and causing belts to break before. When the roller brush can't spin because it's bearings have worn out, the motor shaft continues to try and turn the belt, but since the belt can't spin the motor shaft at that point burns right through the belt.

To make sure that it's your roller brush, remove the brush from the vacuum cleaner, and hold it using just your two pointer finger tips, holding just the bearings caps at the end of the bar, and not the bar itself.

Try to spin the brush using your thumbs. Does the brush spin freely without resistance? It should spin completely around 3-4 times on each spin. If it doesn't spin, then your bar is bad.

If the brush doesn spin, and it continues to break belts, this means that the belt is being installed incorrectly, and is being pinched by the roller brush. Pull the belt forwards after installing to make sure the brush spins freely.

Hope this helped you,

Hi There,

When a belt breaks immediately after installing it, this can ONLY mean one of two things. The first is that the belt was put back on incorrectly, and it may be pinched underneath of the beater bar. This would cause it to break immediately, but I seriously doubt after 4 belts that you put the belt on wrong all 4 times.

The second, and more probable cause is that your roller brush has gone bad. This could be why the belt broke in the first place. In order to test to make sure the brush is bad, unscrew the bottom plate, and remove the brush like you were changing the belt.

Hold the brush at the very end on both sides, using only your finger tips. While holding just the bearing caps, try spinning the bar with your thumbs. Does the brush spin freely in your hands? It should spin completely around 4-5 times on each spin. If the brush will not spin, or if you feel any resistance to it spinning, this is the reason why your belt continues to break.

If the brush can not spin, the motor shaft will continue to try and spin the belt, but since the brush doesn't spin, and the belt doesn't move, the motor shaft will just burn right through the back end of the belt.

If your machine is actually the model that's listed on this Fixya repair page, the Dirt Devil Featherlite model M085845, then your machine uses the following roller brush:
Dirt Devil Plastic Brush Roll for Model 085845 Part # 2-881020-000

The next time that change the belt, install the brush back into the machine, but this time pull up on the belt towards the brush to make sure that the belt spins freely, and spins the brush as well. If the belt doesn't spin the brush, there's some issue, and the belt will break as soon as you turn the machine on.

I hope this helped you. If you find out that you don't need a new brush, feel free to use the comment section here on the repair page and let me know, I'd be happy to walk you through some more advanced diagnosing. If you found this helpful, please be so kind and rate my repair and / or leave feedback for me.

Thanks so much,

Hi There,

Here's how you can replace the belt on your Eureka SmartVac 4870. I have taken pictures of the repair to help you better with this.

Here's what you'll need in order to complete this repair:

- Eureka Style R Extended Life Replacement Belt, Part 61110
- Eureka SmartVac Model 4870 Roller Brush Assembly, Part 61520 (Only if the brush no longer spins, or the brushes are worn out)
- Phillips head screw driver

Step 1. Turn the vacuum upside down so that the brush roller is facing upwards. Unscrew the three screws that I've highlighted in red.




Step 2. Remove the bottom plate after unscrew the three red highlighted screws. Once you remove the bottom plate, you'll have full access to the roller brush and belt area. Remove the roller brush by pulling straight up on the roller brush itself. Discard old belt, and test roller brush to ensure that it spins freely by holding the very end of each side, also called the bearing caps with just your finger tips. Try spinning the brush with your thumbs. The brush should spin several times around with each spin. If you notice the brush doesn't spin at all, or if you feel some resistance when you spin the brush, this means that your bearings are either gone, or will be soon. It may be time to consider a new roller brush at this time.



Step 3. Remove the new Eureka Style R belt from the packaging, and wrap one end around the the metal pin, on the opposite side of the roller brush. This pin is actually the motor shaft that spins the belt, which spins the brush.



Step 4. Wrap the other end of the belt through the side of the roller brush that has the pulley, and use the roller brush to stretch the brush roll back into the agitator housing. Make sure the end caps fit in the housing correctly by making sure there are no gaps between the roller brush housing and the end caps of the roller brush.



Step 5. After reinstalling the roller brush back into the housing with the belt attached, pull the belt forwards towards the brush. The brush should spin when you do this. Make sure that the belt is not pinched underneath of the roller brush or this will cause the belt to break immediately when you turn the vacuum back on.

Step 6. Reinstall the bottom plate, making sure that the little notches on the front end of the bottom plate tucked underneath of the reverse notches on the bottom housing of the vacuum cleaner. Tighten all 3 screws back into the bottom plate. Make sure the vacuum is set to carpet mode, and turn the vacuum on.

If you have any questions about this repair, or if you notice that the roller brush stops when the brushes hit the carpeting, please just use the clarification request form here on the Fixya repair page. I will then be happy to walk you through a little more advanced repair of replacing the clutch in the Eureka SmartVac that controls the rug/floor switch. Most of the time though the belt will be all the vacuum needs.

I hope that this was helpful information to you. If this helped you, please be so kind and rate the repair as helpful by clicking on the thumbs up icons in the top corner of this repair.

Greetings,

When a brand new belt breaks in 5 seconds, this can only mean 1 of 2 things.

1. The roller brush itself may be bad and need replacing. If the roller brush's bearings lock up, and the brush can no longer spin freely, this will cause the belt to burn up immediately after you turn the vacuum on. You may test your roller brush by taking it out of the vacuum, and hold it on the very ends of the brush with your fingertips. Make sure you are only holding the bearing caps and not the brush itself. While holding the two bearing caps with your pointer fingers, try to spin the brush with your thumbs. Does the brush spin freely? If no, then you'll need to buy a new roller bush for your vacuum, unfortunately the bearings are not sold separately on Hoover vacuums. If the brush did spin freely (you should get at least 7 rotations out of one spin) then see reason number 2 below.

Your model uses Hoover Agitator Brush Part 48414132.

2. The belt was installed incorrectly. When a belt breaks immediately like this it can also be a result of it not being installed properly. When installing the next belt, after you have put the roller brush back into place, pull forward on the belt to make sure that the brush spins when you're pulling forward. Sometimes I pinch the belt underneath of the brush roller, and it will not spin freely, and will burn immediately if the belt is pinched.

It really can only be one of these two problems. I hope that this repair solution was helpful to you. If you need me to clarify something, please just request clarification here. If it did help, please be sure to rate my repair Helpful. Thank you so much!

Check your brush. It is likely that the brush is broken and will not spin. Hold the brush by the end caps and spin the brush and if it will not spin freely that is your issue.

belt could be melted to the motor that spins the brush, try free spinning the brush with your hand to see if the brush spins freely, if it does not the brush bearings could be frozen, or just need a simple new belt...hope this helps
