Ahh the good ol electronics on vacuums selling the product again...

not to worry, your feature is working properly, your vacuum is working fine too.

Imagine if you will making a circle with your pointer finger and your thumb. Now put a string or thread across in a straight line there. The string would be the size of the beam of light that the sensor uses. Your finger and thumb are about the size of the tube that the dirt and dust is passing by. Unless the dirt passes and cuts through the beam of light, then it will register. otherwise if it passes around the beam of light, the sensor thinks your carpet is clean.

The opposite sometimes will happen too where it will stay constant red. That means that the sensor is completely covered in dirt and will not register anymore.

Hope this helps.

Red "DIRTY" light is on most of time, even after going over and over what should be clean carpets. Head is lifted, getting good suction. Got a solution?


The sensor that detects the dirt can get dirty causing the light to stay on. Hold the vacuum up in the air or position the vacuum in a way to observe the light when the vacuum is running but the nozzle assembly is not on the floor so it cannot be picking up any dirt. If the light will not go off it's likely the sensor needs cleaned.

The dirt sensor light stays green. It won't turn red, even when I know I'm picking up a lot of dirt.

You can test the board by crossing the 2 connectors to "close" the circuit for the mic (small black and blue wire) while vac is running and light should go to red every time you complete the circuit. WARNING: There will be exposed electrical points on board that could cause an electrical shock!!! or damage to board if not just crossing mic connections.

Green light on comes on when the vacuum is off the ground


It's supposed to do that. There's a small, very sensitive microphone in the elbow of the dirt passage coming off the back of the machine. As long as it's in contact with a dirty floor, the smallest piece of dirt going up through the hose will turn the light to red. Once all the dirt particles have been passed through, it turns back to green.

Vaccum cleaner not picking up (116.36933/Aspiradora)


Joan,

I had a similar problem with my upright and just resolved it today. Mine was also picking up with the beater bar, but not as good as it should and it had very little suction at the hose.

I did everything it said to do in my owners manual...
I looked into every entry to the dirt cup.
I checked for blockages into the bottom of the vacuum.
I cleaned the HEPA and regular filters and dirt cup - still no success.
I made sure the belt was working properly.

I finally sat and looked at how things should get into the clear dirt cup (bagless model).

I finally realized it had to be a blockage in the hose.

I completely detached the hose from the vacuum - this took some muscle.
Took the hose outside and used my high pressure nozzle on my garden hose to spray out the hose. It took a few seconds before a pretty large & stiff piece of paper (2"x2") and much more very dirty stuff finally blew out...
No wonder the vacuum had no suction!!!

The paper that was blocking the hose reminds me of a piece found under a Reese's Peanut Butter Cup! YIKES, it was probably candy causing yet more problems besides the extra pounds!!!

Hope this helps - I'm not an expert, just a frustrated cleaning fanatic who hates it when mechanical things don't work right!

Good LUCK!

Red light stays on


It sounds like the plates inside the vacuum that detect the dirt have become dirty. I don't remember where they are, but I think they're accessible if you remove a certain hose. Again, I don't know which hose it is.

Vacuum stopped working


Hi Melisa
Because it has a dirty fan system where dirt is picked up and put through the fan impeller before it goes up the back spine and into the bag, it sounds like stones or hard dust has entered the fan and bounced off into the motor. Sadly this is one of the most common factors like Orecks that have a dirty fan system. It would have to be repaired unless you know how to take it apart and clear it. The green light certainly sounds like something you picked up with the Oreck and it has affected the motor.

Dirt finder sensor stopped working


I had the same problem with a hoover windtunnel 6200 - u5477-900. I removed the flexible hose from top of the plastic tube running vertically along the right side of the back of the vacuum. When I used a flashlight to look into the plastic tube, I could see a clog at the bottom, where the flexible hose curved frontwards towards the brushes. I then removed the 2 screws holding the vertical plastic tube to the vacuum. When I disconnected the plastic tube from the flexible hose at the bottom, I found a clog of dirt and dog hair. After removing the clog and reassembling, the clean / dirty light now moves back and forth from red to green.

Embedded Dirt Finder green light won't come back on - stays red


The dirt sensor is a motion detector. After it gets dirty it will either stay red or stay green. You can have the vacuum serviced at your local vac shop and possibly get this fixed. Sometimes they are as good as new and sometimes they are not repairable. It will not effect anything else though.
