With years of use, you will collect a layer of "micro dust" on the impeller (the fan part) which reduces the efficiency. A toothbrush and some mild cleaner with gently scrubbing will restore it's power.
The impeller is that parts that spins that you can see when you take the top off to fill the water tank.
Hope this is the answer that you need!

Is the water seal in place or missing? Another cause would be a bad motor, running at a slower speed will mean low suction. If it is a motor, then you would have to replace it. Is the suction low at machine without the hose, if it is ok then may be a clog in the hose.

Cannot separate water basin from motor


You need to unlock the latches on either side of the water basin.
If they rusted or froze into place you may have to break them.
There are two latches on either side of the water basin.

The equipment does not start and a strangeous sound is heard when you try to start it and then nothing is heard.


  • I can guess that it is a burn out motor . Lift the top off of the basin where the water goes and look at the bottom of it. There you will see the separator and this turns when it is running. Turn on the machine just for 5 to 7 seconds to see if the separator is turning and by what your telling me it may turn for a second and then stop. This is a seized motor and it is mostly due to age on vacuums but with the rainbow they also have condensation getting in there so it can happen even quicker. If you did not take the separator apart everything you finished vacuuming then it had condensation on it for along time after you finish vacuuming and we all know what happens to metal when we get it wet and let it sit.....that's right RUST! It may not be all visible but it rusts up inside where it is seized. If in fact it is seized then you are looking at getting a new motor and depending on the age of your rainbow you may want to just move on and get something newer with more suction as they do not have the suction that the new machines have today with all the improvement they have made in the last five years....cyclonic action etc.
  • Thanks for the question and good luck.
  • Please try to remember to give me a good rating if this was helpful info. Thanks again.

MY RAINBOW VACUUM HAS LOST SUCTION POWER AND i DON'T KNOW WHY


Your Rainbow E series has lost suction power, because you need a new hepa filter, ot your water basin gasket is messed up, or the center motor gasket is messed up or out of position.

Make sure your water basin is not cracked or broken, also.

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

Thank you,

Need to replace clips that hold motor to the basin on Rainbow vacuum


There are small brass colored pin going through the latch half way between the upper portion and lower portion, where it is attached to main body of the Rainbow. Take a small nail or dowel put it directly on one end of the brass pin and tap till it comes out. Put the new latch where the old one was and insert the pin till it stops. Then tap slowly so as it pushes though the other side you can line up the hole. When the pin is flush, you are done.

My Rainbow has no suction

If it is an earlier model, everything applies, except for the filter. They do not have filters, on any of the earlier models.

Rainbow water not spinning


All Rainbows - remove the hose and turn it on without the hose plugged in - if works better - hose is clogged

If it works bad even with the hose out:
E-series Rainbow - take HEPA filter cartridge and try then. If helps - you need new HEPA (you can get it here)

SE Rainbow vacuums - remove exhaust cap

and you may find a dirty sponge in there - just remove it and it may help.

If none of that made any difference - you may need it to be checked. If you do not mind shipping - our info is HERE

Rainbow vacuum-water not spinning


Remove hose and turn on the unit with nothing on the intake - see if it helps - feel the suction with hand.

a) If it works fine without the hose - look for a clog in the hose, wand or the nozzle

b) If the suction is weak even without the hose:
Clean the separator,
If this is e-series or E2 Rainbow - remove HEPA and try vacuuming without it (sometimes it is too dirty so stops good airflow). New HEPAs HERE.
If this is SE Rainbow - remove exhaust cap and if there is a sponge - take it out

Still no luck - It has to be serviced

Good Luck,
Rocky

Need to know how to install rainbow water pan latch and spring latch

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 latch can be replaced but I believe it is a pop rivet that holds and replaces the old latch and to replace the new latch, I have seen it done but if you don’t have the right tools you may want to contact your local vacuum cleaner dealer in your area, it can be done. 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.
