Eureka boss 4d 5893 AVZ Brush roll is not turning. Belt is on properly and I believe it's seated correctly on both sides. When the brush roll is removed, only one side seems to rotate, while the other side remains stationary. I am aware of the reset button and it trips when I turn the unit on. Shouldn't the roll be able to turn freely when it's put on, and turned off?

I've posted the steps below, but I am also going to give you a link to the manual, as it includes pictures that might be helpful. Look for page 4.

1) Use handle release to lower handle flat
onto floor (Fig. 1).
2) Remove 4 screws from brush roll cover.
(Fig. 2).
3) Lift off brush roll cover. (Fig. 3).
4) Remove brush roll and belt. Thread new
belt around motor shaft and brush roll
(Fig. 4).
5) Insert left end of brush roll first. Make
sure end cap fits into base. Pull right
side of brush roll to stretch belt and
insert right end cap into base (Fig. 5).
Make sure it slides into position.
6) Rotate brush roll 2 turns to center belt.
7) Replace brush roll cover (Fig. 3).
8) Replace 4 screws (Fig. 6).

Check to see that the beater brush is not frozen up. Pull the brush and clean it, spraying some WD40 on each end piece that holds the brush in place. Also be sure the belt is properly installed so that the brush turns in the correct direction. If the brush is not turning or not turning in the correct direction, it will not beat the dirt from the carpet so that it can be picked up by the vacuum's suction.

This unit has a reset button on the side of the hood. Recline handle, turn power switch on, pressing down in carpet mode, press reset buttonon the side of the hood, the brush should turn on.

Good luck

I have been searching the machine for something which could be rubbing against the belt to cause it to fray and break as often as it does. So far, I haven't found anything. I have heard that the belts, called ribbon belts, are terrible! I find that the belts break faster when I use the hose. I haven't found a way to make a belt last longer.

Take either the plate over the brush roll off, if it doesn't come off, then the top cover comes off, should be 2 or 3 screws on the top to remove. Then you can get to the belt and brush roll. Check the brush roll, make sure the ends turn freely, if not replace it. The belt is either broke or stretched to the point that it won't turn the roll, replace it.

I just replaced the belt on my Eureka The Boss Smart Vac (Model 4870D). I purchased a namebrand Eureka R belt from a local vendor. I did my best to follow the instructions printed on the bottom of the machine. I turned on the vacuum cleaner and the belt brush was spinning! I dropped it into vacuuming floor mode and the belt wouldn't spin no matter what level I put it on.

I called the manufacturer (1-800-282-2886) and spoke with a very nice woman on the phone. While I was speaking with her I noticed that a silver screw was lodged within the "brush roll control" yellow selector switch. With some shaking it became dislodged and I was able to put the "brush roll control" into the hard floors setting and turn the "carpet height adjustment" all the way to the right, so that it was facing the word "low." I then followed the instructions for replacing the belt again.. (1) remove base plate (2) remove brush roll (3) place new belt around motor shaft and then around brush roll (4) insert left side of brush roll before right side (5) rotate brush roll to be sure belt is centered (6) replace base plate, making sure to insert under 4 little tabs before securing with screws.

It appears that it is very important that the carpet height and brush control adjustment are set to their highest point possible (hardwood setting) in order to get the brush to roll in a carpet setting.

"R" is the correct belt for the 4870 and should be correct for all other 4800 models.

Thank you for posting your problem to this website. If I hadn't seen that others were having trouble, I would have just given up. I hope this long post helps someone that was in my situation.

The top comes off to get to the belt and brush roll. Did you check the brush roll to make sure that the ends turn freely, or is one not turning, the belt is a lon life "U" part #61120A. The brush roll is what drives the vacuum, but if brush roll or belt is bad, then it won't drive it.

If the model number is 5892AVZ, either the brush roll is bad or the brush roll motor isn't coming on to drive the brush roll. There is a circuit breaker, make sure it didn't trip, reset it if it has.

There is also a reset button on the side at the bottom. Good luck.
