Question about Eureka Smartvac 4870 Bagged Upright Vacuum

Open Question

Eureka 4870 cuts off after 1-2 minutes

I have a Eureka SmartVac 4870, about 18 months old. I just started having a problem in which the vacuum shuts off after running for a minute or so. The power button stays in the "ON" position, but if I press down on it a bit, the vacuum will kick back on some, as if it's "Shorting".
However, I don't think a loose wire is the problem, because if I first start it when cold, and wiggle the power cord, bang on the housing, or tap on the power switch, it will keep running until a minute or so has passed.

I've already changed the bag/cleared the tubes/cleaned the roller/cleaned the filters/changed the belt, to no effect.

1) What could be the causes?

2) Can anyone direct me to a pdf of manuals/parts lists for this?

SOURCE: My Eureka The boss Smartvac Model #4870 roller

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:

Eureka Boss 4870gz shuts off (thermal protector) after 2 or 3 min


wiggle the cord while running the vac. if it cuts off from that, then you most likely have a bad switch or cord. if the motor was bad, you would smell it. it smells aweful.

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 the Boss SmartVac just turned off and won't turn on


Make sure it is not the electrical outlet that has tripped. If not then you basically have 3 choices. Cord, switch, motor. A service tech. should be able to diagnose.

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.
