Check with a local appliance parts supplier. You may have to contact Rug Doctor directly to determine availability and source.

You will need to pull the roller out and clean it. I think some of the strings are tangle up at the end of this roller. (Most rollers will come apart at the end for cleaning.) Make sure that the strings are not tangle up on the belt pulley as well. I hope this will help you.

More than likely there is gunk underneath the endcaps. In the small airdriven attachment those end caps come off. It's likely true of the beater brush underneath too.

Where does the piece go to rise and lower the brush


HI There,

The part that raises and lowers the height adjustment goes underneath of the hood on the vacuum cleaner, and is held on by the carpet height adjustment know on the top of the hood.

I've done a repair below that explains how to get the hood off of the roller brush housing, and replace the knob next to it which is the rug/floor selector knob which is the one right next to the height adjustment part. The repair on your machine will be the exact same process however. Hope this helped you:

Hello,

If you've already changed the belts and the machine still won't run, it can really be only a few things.

The first thing you should check to make sure that the roller brush is good. You may do this by removing the bottom plate, and then taking the roller brush out of the vacuum2_bing.gif. Hold the bar using just your fingertips on the very ends of the brush on the bearing caps. With just holding the bearing caps with your fingers, use your thumbs to try and spin the bar. Does it spin freely without any resistance? If no, then you'll need to replace the roller brush. Here's a direct link to the exact roller brush for your Hoover Windtunnel Self-Propelled:
Hoover Windtunnel Agitator Brush Part # 48414069

If the roller brush spins freely several times on each spin, then your machine may possibly have a bad Rug / Floor actuator arm. This part controls the internal pulley that stops the roller brush when you turn it from carpet to floor mode.

I'm guessing that this is probably a more likely cause of your brushes not spinning. Here's how you can check this part:

Step 1. Make sure that the vacuum is unplugged. Turn the machine upside down so that the brushes are facing upwards. I find the easiest way to do this is to put the brushes on top of a counter top or work bench with the handle of the vacuum resting on the floor. Remove the four screws that hold the bottom plate in place. Remove the bottom plate, both belts and then the roller brush from the machine:


391f9a0.jpg
Step 2. There are 3 screws that hold the top brush cover in place that need to be removed. On the right side the screw is down below the transmission to the right. There's also a screw in the agitator tray, in the middle that needs to be removed. NOTE: This small screw in the agitator tray is only present on some models, you's may or may not have this little screw, but all models will have all other screws circled. I have circled both screws that need to be removed:


a2c6df2.jpg
The screws on the left side that need to be removed are also circled. One screw holds the upper brush cover on, and the other two screws secure the hose in place. Remove all three screws as well as the transparent hose cover:


e00d104.jpg
Step 3. After all of these screws have been removed, there are two clips that are the last things holding the top brush cover onto the vacuum. Use a flat head screwdriver to push these clips off on both the left and right sides. The right side clip is near the pulley that the flat belt2_bing.gif rides on, and the left side clip is next to the internal hose.


b39ff0c.jpg
Step 4. Once both of these clips have been pushed so the unhook from the lower agitator housing, remove the top cover. On the top you'll see two selector knows, one for the height adjustment, the other that controls the rug / floor setting. Turn the cover over and look at the opposite side of the knob that controls the rug / floor selector. There should be an arm that extends out that looks like this:



305a968.jpg
Sometimes this arm will break off, which will prevent the actuator arm from activating the rug carpet setting. The machine basically will always be set to bare surface floor mode. Is this arm broken off on yours? If yes, then here's how you can remove it from the machine.

Take your flathead screw driver, and place it underneath of the of selector knob on the top of the cover. Simply lightly pry upwards to separate the knob from the arm underneath:


a638606.jpg
Replace the actuator arm with a new one and see if this fixed your problem. If this was not the problem, there's really only one other possible thing it could be, but I rarely see this go bad. Please let me know if this fixed your problem, or if it is something else wrong. I'll be happy to then walk you through the last remaining possible problem.

I really hope that this repair was helpful to you. If you did find it to be helpful, help other Fixya users with the same problem find this repair by rating it helpful. You can do this by clicking on the thumbs up icons in the top of the repair.

Thank you very much,

Riccar 8000 Series Brush Won't Engage


Greetings from GoVacuum,

It sounds like you have a bad part called the Clutch Rubber Pad Holder Assembly on the inside of your roller brush. I believe that the problem you are having is that the roller brush does not spin, but the belt is properly installed and engaged, correct? This can only be something inside the clutch mechanism in the roller brush itself has gone bad. The easiest way to fix this is to purchase a new roller brush assembly, which can be purchased here; Riccar 8000 Series Roller Brush With Rug/Floor Switch. I realize that this is a rather expensive part at $43.00, but it may be worth it for you to avoid the aggravation of having to take apart the roller brush piece by piece. To test out this part, and verify that it has gone bad what you need to do is turn the vacuum upside down and remove the bottom plate. Then make sure the vacuum is in the Carpet setting on the Rug / Floor switch on the top of the vacuum. Now while the bottom plate is off, turn the vacuum cleaner on. Can you see the belt spinning on the brush? Is the brush roll itself not spinning? If the belt is spinning on the pulley, but the brush itself is not spinning, this indicates that it's bad.

If you decide that you'd rather just replace the rubber gasket inside of the roller brush, here's a detailed repair solution for you on how to replace this part;

Step 1: Remove the roller brush from the vacuum cleaner completely. If you need help with this step, please see my repair solution for the belt change on your model here; http://www.fixya.com/support/t4184186-replace_belt_riccar

Step 2: Once the roller brush has been removed, turn the brush on it's side, so the metal end that has 2 teeth protruding out is on top, and the end that has the rubber cap is downwards. Use a flat head screw driver to remove the clip on that outside of the brush;


7c5e20c.jpg
Step 3: Remove the clip on the outside of the brush with a screw driver, then remove the metal end cap from the brush. The entire roller brush is spring loaded, so you'll need to apply some downward force to these parts so they don't just shoot off. It's really the easiest if you lay out the pieces to the roller brush in the order that they were taken off, to make it easier when you are reinstalling these pieces. After removing the metal cap at the end, this is what you should see:

23dd8af.jpg
Step 4: There is a small plastic washer underneath of the metal cap. Remove the washer, and the plastic part underneath of the washer that has two teeth protruding outwards. This is how the brush should look after this step;


d940b1d.jpg

Step 5: After removing the plastic part with the teeth, the next part of the brush is the metal part which is called the Inside Metal Cam. The Inside metal cam is the part that the actuator arm for the rug / floor switch connects into. Remove the Inside Metal Cam from the brush. This is how it should look after this step;


fd04308.jpg
Step 6: The next part underneath of the Inside Metal Cam is called the Agitator Pulley Clutch. This is the part that the belt rides on. Remove the Agitator Pulley Clutch from the roller brush. This is how it should look after the Agitator Pulley Clutch has been removed;


f634050.jpg
Step 7: The next part that needs to be removed is called the Agitator Compression Spring which is used to spring load the entire roller brush. Simply slide this spring off the Agitator Shaft, and this is how it should look;


02b8973.jpg

Step 8: After the Agitator Compression Spring has been removed, turn the roller brush on the side, and remove the Agitator Shaft from the roller brush. This is done by simply pulling the other side of the brush end which is covered by a rubber boot. This will remove the long metal shaft which is sticking up. This is how it pulls out;


dec4f58.jpg
After the shaft has been removed, the other end of the brush should look like this;


0c192ff.jpg
Step 9: The next part that needs to be removed is probably the part that's worn out on your vacuum. The part is called the Clutch Rubber Pad Holder Assembly, Riccar Part Number C012-0400. The way the roller brush works is, when you move the Rug / Floor switch to Floors, the clutch (the parts that you just took apart) loosens up so that the belt is still turning, but the pulley that it spins on is not tight against the brush. When you select the switch to carpets, the clutch then tightens the pulley against the Clutch Rubber Pad Holder Assembly so the when the belt spins on the pulley, it's also now going to spin the brush. Over time this part gets heated up, and the rubber wears down to a point where the pulley will no longer stick to it, which causes the exact problem that you have, where the belt is installed correctly, but will not spin the brush. Simply use a flat head screw driver and pry directly on top of the brush strip, and remove the Clutch Rubber Pad Holder Assembly;

rsz_1riccar_repair-9(1).jpg This is how the part looks by itself; t1riccar_repair-14.jpg?732892 If you're interested in purchasing this part, you may contact your local Riccar dealer, or we can also supply you this part. Once again this part is called the Clutch Rubber Pad Holder Assembly, Riccar part number C012-0400. Please just email me at chris.jones@govacuum.com for pricing on this part if you need it. I hope that this repair solution was helpful for you. If this didn't fix it, please contact me, I'd be more then happy to try and help you diagnosis this problem further.

While vacuuming a rug on high (carpet setting) the power suddenly decreased. Now it will only run with low power, not picking up items on carpet


It sounds like you burned the belt. Turn the unit over, remove the cover plate where you see the brushes. On the side of the brush roller is where the belt is located. The belt should be very tight on the roller. Also, you may see little black rubber pieces stuck to the area where the end of the roller is or in the part where the belt runs. Get your owners manual out and read how to change the belt. I'll bet when you ran over the carpet it hung on some of the nap and hung the brush roller up for a second or so. That's all it takes sometimes to fry the belt on some vacumes. Sometimes new vacumes come with a new belt. Look in the bag or box and install it.

Brush roller does not rotate around


If the rotating brush doesn't turn, then it's almost a certianty that the belt (which connects the rotating brush to the motor pulley of the vacuum) is either horribly stretched or just plain broken. Either way, it needs to be replaced. The correct Hoover belt part # for your vacuum is 38528040 (changed from the original part number of 38528027). This is a very common Hoover belt, but would recommend your best source as being a local, independently-owned vacuum dealer dealer (as opposed to a deprtment / big box store, both of which carry very limited belts).

Bottom roller bush does not spin


Sounds as if the v-belt came off the idler arm or you broke the v-belt. Either way, take the 4 screws out of the plate around the roller brush and make certain the belt is there and that it sits on the idler wheel. If you remove the roller brush you'll see the wheel. Pay attention to how the ends of the roller brush go back into the vacuum when inserting it and put the plate back on. Also check the thicker main belt is in place as well, it's to the left of the v-belt.

Also, the roller brush should stop when you put it in the upright position. Next time just stand it upright so the throw rug doesn't get drawn quite so far into the vacuum.
