Why does not my rainbow vacuum will not pick up dirt

The answer is simple...vacuums with filters allow air and anything finer than the size of the filter holes to pass through...if you hold a light over your bag and turn the vac on, you will see an explosion of fine dust coming from the bag...Vacs work on airflow, so the less air flowing through the bag, the less dirt you pick up...clogged bag = no airflow=no cleaning. Bagless vacs should have the filters cleaned after every use, and the canister emptied and washed. Buy a Rainbow to eliminate these problems.

Do you have the water level set right? Is there an elbow missing inside the tank?

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,

<p>Did you recently remove the brush roll? If you installed the brush roll in backwards, then this can happen.

The Rainbow must have water as this is the only way it filters the dirt before the motor. If you don't use water, all the dirt will go through the motor and could create serious issues. We have a cleaning service that will clean your Rainbow inside and out making it like new. Call us for details.

Hi There I would suggest you have a blockage in your head. Turn it over and remove the base plate. I suspect you will have a build up of muck and junk there. Remove it all and check your Rainbow belt while your there.

Have you tried cleaning out under te plastic cover? Remove it as you would when you replace the belt I get stuff caught in there or just inside hard metal tube there is a small magnet that will catch things and sometimes block it up. Use hose to **** it all out and clean. I find this helpful when it doesn't want to pick up as well I know it is time to clean it up.

Hi,
Here is a tip that I wrote about my Bissel but I bet you have the same problem and the hose is clogged...

Your Rainbow might have been damaged. It would be advisable to take the machine to a shop and have them do a cleaning on it. The water is the filter, and there is a separator between the water and the motor. The separator only prevents the water from entering the motor. The dirt that goes in the water is no longer airbourne, so it cannot enter. Without water, the dirt is still airbourne and some of it could have entered. I am sure that most of what was picked up landed in the basin. Is the separator(the little nut on the bottom of cleaner holds this in) full of fluff? Take off the separator nut(there should be a wrench/toothbrush tucked in under the cleaner that is used to remove separator and clean it.) Is there fluff visible up in the machine? If so, definitely take it to a shop. The separator must be cleaned after every use. Never store water in the basin. Those are the 2 main rules for care and use of your Rainbow. Well, good luck with your Rainbow. They are truly great vacuums. Let me know if this helped you. Thanks Rene(the VAcuum Doctor)

tell your vacuum shop.
