Re: 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

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.
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.
http://geeksquad.fixya.com/ThreadView.aspx?prdid=19674&thid=576894 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.
