No spinning in the power head

Check the electric cord on the power head.

There are a few problems with this head which we frequently encounter.

One, the motor get's clogged up and the brushes get stuck in the motor.
The red top circuit breaker fails, and under load, the motor will stop.

Take the 2 wires off of the breaker in the power head, and short them together to find out once you have cleaned out the motor which will be a mess inside.

The belt if worn will not operate the power head if you put your foot on it and see if the brush spins.

The belt is a major problem as well as the replacement of the motor.

The motors are 45.00 CAD and belts 4.00 Cad.

The yoke on the power head also gets clogged and needs cleaned out.

Try these procedures and I hope all works out for you!

Attach hose with out power head to the rear of unit and turn unit on. This is a pretty effective way of eliminating anything that may be in hose. Also check belt on power head. P.S don't forget to put rear cover back on rainbow,

You'll need to open the vacuum head and remove the beater bar. Clean up the bearings at each end of the beater bar and reassemble the head.

Possible bearing in the motor or brush roll is locked up. Check to see if the light comes on. If it does not, then you have an electrical problem but that is a separate problem from the belt being tight. Let us know if you need service....www.rainvac.com

You can check the belt. If you rainbow belt is broken the power head will seem to spit dirt back out.

Try putting on a new belt.

Even though the belt is intact it can still be stretched and if it is it won't turn the brush roll when it's on the carpet. Here is a link to the belt you need and to a manual you can view:

Are you talking about the large power head (ised for floors) or the smaller power head (for upholstery)?

If you are talking about the large one the first thing I would check is the belt (accessed by turning the tiny lock knob on the bottom with a flathead screwdriver).

If the belt looks ok the next thing I would check is make sure an accumulation of hair hasn't built up on the ends of the roller....take the roller out and turn the roller by hand holding onto one of the ends...it shoudl move freely....

hello lilbutmunch1,
The brush is motor/belt driven so you probably either broke the belt or it shifted off the motor or brush shaft. I suggest you unplug it,flip it over and look for screws that hold the baseplate together.. remove those screws and seperate the baseplate to gain access to the brush and motor head. Once open, it should be fairly obvious what the problem is.. a broken belt, a belt that has shifted or the brush won't spin freely due to an obstruction. Hope this helps..
