Question about Vacuums

Roll brush stops on contact with carpet

I have a Eureka Boss SmartVac (4870 series) that is having problems with the roll brush. It rolls fine until it has contact with the carpet then it stops until it lift up on the vacuum a bit. I have it set on the highest carpet setting (my carpet is not that high nor that plush), I have cleaned the belt area with alcohol as well as the belt, oiled the roll brush ends (they move freely.) I changed the belt once before and it helped the problem for only a little while before the symptoms started again. Do I really need to change the belt every month on this vacuum? Surely there has to be a better solution, these belts are aprox. $6 ea. I called the company (not too helpful) and they mentioned the possibility of adjusting a tensioner. Is that something I can do myself if that is the problem? Please help; I'm very frstrated with my less than 2 yr. old vacuum.

    What would cause this if the belt is in the correct position (its the original belt in the same position as when it was purchased)?

    I have the same problem with mine. It is very frustrating. I think the engineers who design this piece of junk out smarted themselves. In an attempt to save the motor from strain, I think they made the vacuum unusable.

There could be a problem witht the tensioned. Take off the top cover and try to see why it isn't pushing the belt when the handle is tilted back. Hopefully the belt is in the proper position, I have seen where the belt was put on the wrong side of the pulley it is supposed to ride on.

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

Does the vacuum lose suction when in the floor mode if the belt is broken?


To put it simply, no. By floor mode I'm assuming you're stopping the brush roll from turning so that you can clean hard surface floors instead of carpet. When the brush roll doesn't turn you do lose agitation which vibrates the carpet so that the dirt is more easily picked up by the vacuum. But you don't lose suction because the brush is not turning.

Brush roll belt stops turning when in position to vacuum. Does turn when vacuum is turned onto side. Belt is in tact, brush roll is fine. What's going on?


I think I know what the problem is with your machine. It's a rather lengthy repair, and I'll be happy to photograph it for you (like I do on most of my Fixya answers), but I'd like to know before doing all of that if you still need help, or if you've already fixed it.

Thanks,

CJ

My Eureka The boss Smartvac Model #4870 roller brush won't turn even on the highest setting and the belt smells hot. we took the belt off. How can you tell if it needs replaced?


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:

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:

The brush does not spin when making contact with carpeting


I tried the electrical-tape-around-the-wooden-spindle technique. After a minute or so, it's back to functioning normally.
