Yes, but just the D4 variety, not D2,D3, or E

The main thing to remember about this great vacuum you have is to always dry out the bowl or at the very least keep the bowl separate from the vacuum (top). The D4 motor was and still is the biggest and best motor EVER put in a vacuum, but if you let the moisture sit on this motor by not drying the bowl then what will happen is the spring loaded carbon brushes that make contact with the motors armature will ever so slightly 'stick to the armature. Then when you go to turn the vacuum on the motor will not even have the needed chance to begin it's rotation.Electricity in a motor has to move it's counterparts or it will instantly short circuit. Now believe it or not, as powerful as this motor is, if it can't move it will short. Ironically, you can do one thing ritualistically each and every time you use you Rainbow so that what I just described will never happen:
Under the top part f the vacuum you will see a pot pie shaped thing with a nut in the center. This is the heart of the Rainbow and it is called the separator. Very simply grab it and give it a spin. That's it! Now you have done the one and only thing to be sure the motor is not going to stick. Yep it was that simple, but if I didn't explain it's importance you would never know why they quit making this great vacuum and instead make the latest and supposedly greatest 'brushless' model E2. Stupid in my opinion. All they had to do was put a message on the top somewhere saying, " Before operating, unplug 110V plug, flip top and spin separator by hand to be sure it is free"

How do I change the bag in a Kenmore Whispertone 300


Read the instructions.
My new replacement bags have the instructions right one one side of the bag itself. or if you have the book read the instructions.
Mine is a Kenmore Whisper tone but not 300 so I won't pass on my instructions but my bags fit different Whisper tone Vacs.

Rainbow power head works but canister dont model d4


Chances are the motor died or went bad.
You would have to get a new motor.
You can find one here:

Rainbow D4 SE motor 120V

Or a more cost effective refurbished D4 motor unit here:

D4 Rainbow leaking water around the water basin while running. Already replaced the seal. Still leaking.


Clean the water separator. Use a tooth brush if you do not have the Rainbow separator cleaning brush. It is the same thing, and works perfectly. :-)

I want to take apart and clean my D4C Rainbow and my E series 1 speed, I bought both of them on Ebay, and both have odors,( They are suppose to be the vacuum that cleans and purifies the air) that leaves...


Sorry, but a Rainbow D4 has no filtration at all. The E series has a HEPA filter that needs replacing. You can put liquid Lysol in the water on the D4 and that will help

I just purchased a rainbow D4C, after purchasing i was told i should have purchased the SE model. whats the difference?


There is only one difference between the D4 and the D4 SE, which stands for D4 (Special Edition). It is the exhaust plug screws in on an SE and snaps in on a regular D4.

Then the SE-PE came along, which stands for (Special Edition-Performance Edition) which has a more powerful motor, with larger motor brushes, for more power and runs on 9.8 amps, where the regular SE and D4 run on 8.8 amps. It also has the newer PN-2 power nozzle, which is very much like the latest E and E2 series Rainbow vacuums, instead of the earlier rectangular ones, that have the bottom metal plate, which will rust. You can upgrade your D4 to one of these, though you will need the electric hose with gas pump style handle, with the built in power corn in it.

They are all D4 models.

If you have any more questions let me know. I am a Rainbow seller, and a Rainbow expert also.

Thank you,
Ralph

I don't have instructions for the Rainbow shampooer. I'm not sure how much water to put in, or whether I put water in both reservoirs. Does anyone know?


Water only goes into the cub in the handle. The dirty water gets put into the bowl on the canister part.

Older Rainbow Noisy
Posted by Capt_Troll on May 06, 2008
I Have an Older Rainbow (i think it's a d4)
my Old roommate ran it once without water.
it Still works now (with water), but
it's Very noisy on start up
Also I Can't seem to remove the separator (no instructions) but the nut at the end of it appears to free spin the motor when i try to turn it.
Can I Take this apart and Clean/lube it? And if so how? Or is this thing on its last legs? Thanks



Hello,
I would advise you to ALWAYS to FIRST UNPLUG YOUR VACUUM before beginning any service procedure. Rainbow E Series Canister Wet/Dry Vacuum. The Rainbow D4 is an older Rainbow Vacuum and the part where the separator is part of the armature, the separator should be able to be removed and that might be one of the things making noise. As normal maintenance the separator should be removed and cleaned after every use and re-installed, then place a newspaper or towel under the motor unit and turn on the Rainbow and spin the moisture out of the motor unit. This should be done every time you use it. Other wise the Rainbow has 3 fans in the bottom of the motor and if they are weak they will make noise from the motor unit as well. Watch out… the repair of the Rainbow D4 may exceed the cost of a new motor of which will solve your problem of noise and separator --- compare the cost and the labor and make a decision. If you have further questions please feel free to contact your local vacuum cleaner dealer. . So if you need further assistance, please feel free to contact your local vacuum cleaner dealer in your area or in the yellow pages, or contact the factory phone number or website to further assist you with your questions.
