Question about Dirt Devil Reaction Twin Cyclone Upright Vacuum

Dirt Devil Dual Cyclone - low suction, can't find clog, trying to take apart

I have an upright Dirt Devil Dual Reaction Twin Cyclone (model R110000). It seems to have a clog, as I only get very wussy suction from both the main part and the hose attachment. Using a sink drain unclogger (hey, it was handy!) I\'ve plumbed all throughout the hoses -- from the brush area up to the cannister entrance, and from the tool attachment all the way up the hose and tube to the cannister entrance. That doesn\'t mean, however, that the little metal ribbon I was using didn\'t just push THROUGH a clog. That said, anyplace I can actually see into the tubes/hoses seems clear. AND there buggeruction at the entrance to the HEPA filter.

So my thinking is that there might still be an un-visualized clog just BELOW the joint where the airway has the flapper (the one that switches from main airflow to tool airflow). But that\'s a ****** of a place to get to to double-check. Is there any way to access or detach that section of the hose? I\'ve tried going in through the front panel of the upright part (the one you\'re looking at if you take the cannisters off the machine), but even after loosening all the visible screws the panel still seems attached at the bottom somewhere. Peeking behind that panel, I can see a screw that might be holding the hose connection onto the back, right at the place where there MIGHT be a clog... If I could just get in there and unscrew that screw, MAYBE I could detach the hose and look inside... Or maybe this isn\'t the way to go at all. lol

I need some professional insights here. Thanks for any help you can offer!!

Hi There
After the extensive checks you have carried out. May I respectfully suggest you check all your air filters, as a 'clogged up ' filter will produce the same kind of symptons as a blocked pipe. There is a very strong possibility that a filter on the machine is clogged and that's what is casing your problem

Testimonial: "I even checked the unit without the filter in place, and the low suction problem was not resolved."

    Hi, Peter -- I'm sorry, I should have specified that the HEPA filter was recently cleaned. It still looks good, and there's still suction at that part of the airway. Unless there's another filter somewhere else...?

  • wthillers Apr 13, 2014

    Update: I've about decided it's not a clog issue in the hoses or tubes. So I put everything back together and tested again. Weak suction still. HOWEVER.. I noticed that the cyclone cannisters don't have any "spin," and that would usually mean not enough airflow, hinting at a dirty filter. So, following your suggestion, I simply removed the HEPA filter and tested again. Still no spin in the cannisters. So if there's not enough airflow in the cannisters and it's NOT the filter, what's left: the fan motor?

  • wthillers Apr 13, 2014

    P.S. The unit is picking up some dirt and hair since there is SOME suction, and the brushes are spinning. It's getting deposited in the cannisters but just sitting there; that's how I could tell there was no "cyclonic" activity.

  • wthillers Apr 13, 2014

    P.P.S But a lot of heavier material just stays down in the brushes.

  • wthillers Apr 28, 2014

    Hi, can anyone offer a suggestion? No clogs; brushes are spinning; HEPA filter is clean; and still, there's really low suction, not enough airflow in the cannisters to make a "cyclone", and the motor sounds a little high-pitched like it's working too hard. Is there any possible problem I should check with the motor itself?

  • wthillers May 01, 2014

    And just to repeat: I also tested the machine without the HEPA filter in it, and that made no difference in the low suction problem.

My dirt devil reaction is spitting out dirt everywhere. how do i fix this?

Sound like you have an obstruction in the suction path. check the foot (bottom) check for suction at the hose for blockage. the blockage is where you lose suction.

Dirt Devil Reaction Dual Cyclonic- M110000, "cyclones" not spinni

If the filters have been washed and installed back in instantly there wont be any suction. Check the top filters have been cleaned thoroughly and also check inspection tubes/hose and dust channels to check for a clog. Also check the sole plate / bottom of where the beater bar as there may be a clog somewhere.

When the vaccum is running the motor gets hot & smells & is very noisy.

Sounds like yu may have a clog, either in the inlet by the brush roll, or the hose. If the hose comes loose, see if there is suction there. If no suction then it is clogged. If suction, then the inlet maybe clogged.
