First thing is to check all your hoses, and filters. Filters rob your vacuum of air flow which equals power.. I don't think that you have a clog so much as I am inclined to think that you have dirty filters. In a wet vac, you can rinse your filters out, but they will eventually need replaced. It's a good idea to have an extra filter around for such an instance.

Why does (it) have very poor suction?


The filter can be clogged but look clean. Most models have two filters. Replace them both every few years.

Have suction but belt not moving


Are you referring to the drive belt on the power head? Remove the power head and try vacuum without it, if it picks up fine, the problem in in the power head/hose assembly, could have a blockage inside the head of the hoses attached to the head. If those are all OK, look for an air leak in the system. at/around the bag, canister, loose clamps, etc.

My rainboe has no suction


<p>The hose could be clogged. <a href="http://www.rainvac.com/rainbow-vacuum-schematics"></a>Check the suction on the main unit without any hoses connected. If that seems good, then connect a hose and check suction again at the end of hose. If suction is still good and you are having issues when using the power nozzle, then open up the bottom of the power nozzle to check for clog.</p>

I have a model DC3 rainbow thar has lost suction. what can i do to fix it


Check suction at intake without any hose connected. If that is good, then connect hose and check suction again. If that is poor, then you have a clog. If still good, then check power nozzle by getting into the belt area.

Rainbow Vacuum loss of suction


If it is not the Hepa filter, you can check it by removing it running machine and seeing if there is a difference. It is always good to have your unit serviced about every 5 - 8 years or so.

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

My vacuum will not pick up even fuzz on the carpet


If the suction is strong through the hose and its still not picking up, then something is definately clogged despite the strong suction and rolle brush. Check all inspection tubes including the main dirt channel behind the roller brush. You may find something that keeps getting in the way when dirt or hair is trying to bypass through.

Weak suction on rainbow se vacuum


Check for clogs in the nozzle air passages (remove bottom plate)
Check for clogs in the wand
Check for clogs in the hose (trow in a pebble or a penny and see if it comes out the other end)
Make sure separator is clean.
Remove exhaust cap (sometimes there is a sponge in the cap that gets disty and does not let the air pass through).Have in mind that it will not pick up well if the suction and the belt is good but brush roll bristles are worn and too short.

Good Luck,
Rocky

Rainbow D3C Low suction


You might check the carbon brushes on the motor, it could be that the motor is not running fast enough, which would mean replacing the motor. With the hose off, do you have good suction where the motor goes into the vac? If it is good there, then either the powerhead isn't working or the hose is clogged.
