Question about Rainbow E series Canister Wet/Dry Vacuum

Rainbow dc4 vacume

My vacume is making a sound and smell like the belt is slipping.

I'm pretty good at fixing things but I would love to find a blow up exploded view of my vacume to remove the bottom section. Do you know where I can find this info. I removed the separator and the 4 screws holding the bottom plastic section. Must I remove the nut under the separator to remove this bottom section?

Thanks in advance,

Take off the round flat water seal, carefully, you will have to glue it back on, remove those screw to take off the bottom piece.

When using, smells like vacuum is burning. This is without the powerless attached. What do I need to do?

It is most likely the belt. The belts stretch out over time and start slipping. When they slip they burn. Also check to make sure nothing is keeping the roller brush from spinning.

The response by Lynnette is in reference to the power nozzle....if you are having this issue with the main unit, then it could be the armature is starting to go bad. Have your Rainbow in front of you and give us a call. We can walk you through some steps to narrow it down.

I took the vacuum apart and cleaned it. Now there is an odor coming from the round filter and the vacuum is not picking anything up.

  • hi there
  • Does the odor smell like burnt rubber....if so you may have burned out the belt which is common. The filter can smell if you have pets and the machine will blow the odor back in to the room after the filter gets older.Check to see that the roller brush is spinning when it is turned on if not shut it off and try to turn it manually with your hands. If it turns very easily the belt gone if it is almost impossible to turn you need a new roller brush.You can replace the filter to help with the smell but if it is the belt you smell it will go away in time. Also make sure that you have the container on perfectly as if it is not it will not create a perfect seal and you will have very little suction. The other thing you can check is the hose to see if the suction is good through it. If the hose has good suction then the power head may be plugged with something and you will need to get a screwdriver and take the bottom plate off the same way as if you were changing the belt and then you can look for a blockage as well as access the belt and roller brush. I hope this was helpful to you ...good luck

Work well but smell like a burning belt

If it smells like burning rubber, the belt is probably worn and slipping. If it's another burning smell, your motor windings are probably shorting and will burn out soon

It might be a slipping rubber belt, is the brush roller moving when you look underneath? If it's a self propelled machine there might be another slipping belt. Friction from fast rubbing rubber can smell like it is burning.

My rainbow isn't sucking very well and the power head smells like

Hi there SmartAlec from here. I think that if it is not doing a good job the most likely cause is that the belt in the powerbrush is broken. If you turn the unit on does the brush under the head turn (really quickly). If it does not it will be the belt. Just remove the cover and slip a new belt on. This should improve results about a million times. Hope this helps. Happy vacuuming :)
p.s. dont hesitate to send me a follow up request if this doesnt help. That machine should work nothing short of amazing.

Rainbow Vacuum smells like something is burning.

Your belt is worn and that is why there is a burnt rubber smell. You need to change your belt. You can find a replacement belt and instructions here:

Rainbow will not come back on

Bad idea.... I think the foam got through the separator and into the fan system. When it dried it hardened and now it need to be taken apart and cleaned.

Turn it on for less than 1 sec and if you hear motor making humming sound - it is ALIVE and cleaning (maybe new fan blades too) may be all that it needs. If no sound at all it may be KAPUT. You must have smelled something burning when you turned on and it did not work.

for D4 and SE models - When cleaning I would recommend to replace bearings as they are not that expensive and if you took it apart - maybe a good idea to replace them. Also you probably will need a new gasket as when taking old one off (it is glued) it may rip apart.

For e-series - you will need a new HEPA filter.

Suden loud noise when vacuming carpet


Check that brush roller (beater bar) is free to turn with no obstruction.
If it is still noisey after doing this try this site for Dyson repair manuals.
