Just by what you explained I can tell that it needs to be replaced. The belt doesn't have to be broken to need replacing, if it is stretched and worn then it will slip on the motor shaft and not turn the brush roll and get hot. Here is a link to the belts you need and the manual which has instructions:

The motor spins the belt, and the belt spins the roller. It can either be the roller or the belt on your vacuum. When you take out your roller and spin it between your hands, does it turn or is it seized up?

If it's the roller, you can get it here:

If it's the belt, you can get it here:
http://www.crucialvacuum.com/Eureka-R-Belt-Long-Life-p/eureka_r_belt_long_life.htm

Crucial Vacuum manufactures parts (filters, hoses, belts, etc) that fit the Eureka for typically 1/3 of the price & they have free shipping. They also have how-to videos on youtube to help you replace the part!

Have a Eureka "the boss" smartvac, won't pick up anything when I try to vacuum carpet. Any suggestions on how to fic this problem?


1st) make sure your yellow dial at the top by handle is in floor position
2nd) make sure your brush roll spins when handle is reclined in operating position. (disengage brushroll control by flipping the "switch" towards you)
3rd) check belt to make sure it is not broken
4th) check the brush roll for debris caught in it
5th) check lower hose

Change the belt


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.

Thank you very much,

Chris J.

Brush roller spins until it touches the carpet, then stops.


That means that the belt is stretched or worn. Here is a link to the replacement belts you need and a manual which has instructions:

Eureka 4870: Brush roller turns even in hose setting.


You either have the wrong size belt, most likely too small, or you have installed a new belt incorrectly. When you open the cover on the bottom of your vac, you will see the pulley that moves as you flip the switch from floors to carpet. The belt does not go around this pulley. When activated(carpet) the pulley puts tension on the belt causing it to turn the roller. When switched back to hard floors, the belt looses tension allowing motor to cause suction but disabling roller. Also, the dial on top of vac is only to direct suction, not for disabling roller

New brushroll for eureka smartvac 4870; bristles too long to turn


HI Don't forget that you have a height adjustment control so its better to put it in the highest position - if this is not allowing the roller brush to move properly on the carpet then switch the vacuum off, and lightly trim with scissors on the brush lines. Avoid cutting everything down though - a slight trim should improve things. Generally though when brushes appear too long its usually because the height adjustment dial hasn't been set upwards.

Any belts that can sub. for the RR


Applied the electrical tape to the motor shaft as suggested by another poster. The tape ripped off, but the sticky residue left provides enough friction to grab the belt and cause the beter brush to turn correctly. Thanks

In Carpet setting, the vacuum brush does not spin


I put 3 turns of electrical tape around the area of the beater bar that meets the vacuum belt. This solved the problem short of replacing the beater bar.
