Question about Rainbow E series Canister Wet/Dry Vacuum

Rainbow Vacuum Cleaner starts slow smells hot

Cleaner is actually SE model. When I turn on my cleaner it starts at a slow speed--then the motor heats up and smells HOT as it struggles to come up to speed. I don't want to burn it out and I've taken the cleaner apart but I can't see what the problem is. It seems like the impeller is slowed by something (rust maybe) but I can't get it apart enough to see what is under the impeller. Can't figure out who to get bottom apart. Sound like scale, rust or bearings? Help? Ideas?

    We have same model with the same problem. Motor started to smell bad. I took the vacuum apart to the point of reaching the motor and it appears the bottom will not come off. There must be some secret to how this can be done.

    I have a similar problem. Mine does not have sucking power through the hose as well. The stuff that gets sucked up, gets stuck underneath the cover for the roller. I also have tried everything I can think of, I have not taken the vacuum apart, figured this would mess with the warranty. I thought the motors had a lifetime warranty. I am in the process of contacting rainbow, if I find out any information, I will post it and let you know.

I would suggest that your motor bearings are packing up. You will eventually harm the windings by overheating (although there is a thermal limiter). The bearing replacement is a job for a service shop unless you are pretty handy.

Sounds like the motor is going bad and will eventually not start. I am in the process of changing the motor in mine too and they are not cheap. just search around for a motor

I have a steam vac spinscrub carpet cleaner works good but it just started smelling like it was burning and started to smoke

Anytime someone says they smell something burning on any type of vacuum cleaner of carpet cleaner etc. All I can think of is the belt is rubbing on plastic which would cause the sense of something burning because you possibly are smelling the belt........

The Motor has locked up due to over heating. Once that happens the only way to go is either replace the motor drive or get a new cleaner. Do not try and keep energizing the Vacuum as you could blow circuit-breakers or start an electrical fire.

My Model 2961 Eureka wont take power now?


Anytime that you smell that electrical burning smell on a vacuum cleaner, this is the motor going bad. There are two distinctive burning smells in fixing vacuum cleaners, the electrical burning smell which is the motor, and a rubber burning smell which is the belt.

The bagless vacuums cleaners in general, their motors last usually no more then 3-5 years. The motor in bagless vacuums work much harder then the motors in their bagged counterparts.

The motors in Eureka vacuums can range in price from $70-$120. If you can provide me with the exact model number on your vacuum cleaner (can be found on the bottom or the back of the machine on the sticker that also contains the serial number) I will be able to get you the part number, and price of the motor that's used in your vacuum.

It may be worth considering to just get a new vacuum cleaner at this point. If you'd like me to give you a personalized recommendation specifically for your unique cleaning needs, I'd be honored to do so. Please just let me know what types of floors you have mostly in the home and I'll be happy to share my knowledge of vacuum cleaners.

I hope this was helpful to you. If you found this helpful, please be sure to rate the repair helpful so other Fixya users that have this same problem can easily find the answer.

Thanks so much,
