Roller not spinning on hard floors

Roller Brush not spinning when switched over to hard floor use. I put coffee grounds on the kitchen floor and it just scatters and barely picks up. I can't find the instruction manual. Only had this Dyson for 2 weeks. What's up? Now I have to be a mechanic after paying all that money.

After 2 weeks it should be still under warranty. but my guess is you have hair etc wrapped around the brush tip vac so you can see brush(es) remove all string,hair etc... from around the brush area (may have to remove bottom to get all the hair etc... stuck around it. it also may have been jammed up pretty tight and continued use could snap the belt or burn out motor

2013 Oreck Vacuum . How can I check to see if it is stopped up?


If it scatters the dirt then it's definitely clogged up at the nozzle just behind the roller brush. Turn the sweeper upside down and stand it on the handle. Then look under the roller brush. I have two Oreck's in my house. You can take a screwdriver to loosen the clog and dump out the dirt. Don't try to pick up pine needles as these are sticky and will quickly clog up any vacuum sweeper.

Tip

Brush won't turn after cleaning out debris, belt is fine.


I have the Dyson Animal, the purple one. I frequently have to take the bottom apart where the brush is at to cut all the threads and hair off the brush. This last time it would not spin afterward. As far as I know there is no reset button, however, I did find out that it was switched to bare floors and THAT is WHY the brush was not spinning. Once I switched it back to carpet all was well. I have had this for years and never knew that the brush did not spin when it was on bare floor setting. Hope this helps!

Rubber strip on sole plate?


Hello,

There could be a few things that would cause your Dyson to have no suction. I will give you detailed step by step instructions along with pictures on how you can diagnose this.

Possible Problem #1. The first problem is extremely common. In fact, we probably see between 2-3 of these problems every week. It mostly happens after people take the bottom plate off the vacuum in order to cleanicon1.png the roller brush. What happens is when they reinstall the bottom plate, they put it on on incorrectly. It's actually very easy to do. When the bottom plate (soleplate) is installed wrong, there will be a gap between the bottom plate, and the agitator housing, or the purple tray the roller brush sits in. This will cause the soleplate to be a few inches higher off the ground then it should be, preventing the brushes from even hitting the carpet. This makes it seem to the user that vacuum has lost suction power because without the brushes hitting the carpet, the machine will not pick up very well on floors, but when they use the attachment hose there's plenty of suction power.

Here's a picture of the WRONG way to install the bottom plate. Notice the gap in between the two housings:


9739790.jpg
Here's another picture, that is the RIGHT way to install the soleplate:


8b953d0.jpg
I would say probably 6 times out of 10 this is the problem with the customers machine. If you checked the soleplate and it is installed correctly, move on to the second possible problem.

Possible Problem # 2. Turn the vacuum cleaner upside down so the brush roller is facing upwards. I found the easiest way to work on it is to put it on a counter top or work bench. On the left hand side behind the roller brush you should see a flexible transparent hose that goes from the motor to the agitator housing. This hose actually has a lot of strain on it when the vacuum cleaner is in the reclined position. When the first few series of Dyson DC07 models came out, they didn't make this hose long enough, so when the vacuum was in the reclined position, it would put too much stress on the hose, and cause the hose to actually crack, usually right where the end of the hose that goes into the agitator housing. Examine your hose and see if you have any visible cracks in this hose. If you need to you may just remove the entire hose assembly by pulling on it. It will easily come right out of the machine so you can inspect it better. Here's a picture of where the hose usually cracks:


54cb5e5.jpg
This would also explain why the vacuum works fine when using the attachments, but not on the floors. The attachment hose uses a different suction channel, and when the machine is in the upright position, no suction goes through this hose. If you do find a crack in this hose, the this hose needs to be replaced. Here's a direct link to that hose on our GoVacuum website.
Dyson DC-07 & DC-14 Upright Replacement Internal Hose Part # 904219

Possible Problem #3. I would suspect that this may not be the problem, but if neither of the solutions above worked, then try this one. Dyson's in general are prone to clogging. There are a few clog ports throughout the vacuum cleaner that were added there due to Dyson prototypes becoming clogged at these points. Here are pictures of how and where to check for these clogs. Simply remove the suction port covers at both of these locations:

be63721.jpg

Possible Problem #4. If none of the above solutions worked for you, try this last one. The Dyson DC07 models use a clutch mechanism that stops the roller brush from spinning when changed from carpet mode to bare floor mode. This clutch mechanism is a notorious problem with all Dyson models, in fact they were such a problem that Dyson had to redesign the DC07 model to a non-clutch system. Even if yours is one of the newer ones that don't use a clutch, yours still has a belt inside. You can tell if your model uses a clutch or not by the shape of the roller brush. If your brush is a perfect cylinder shape, yours does NOT have a clutch. To check and see if the clutch or the belt have gone bad, first release the handle on the vacuum as if you were vacuuming carpets. Make sure the machine is set to carpet mode. Now while the handle has been released, turn the machine upside down and see if the brushes are spinning. If the brushes are spinning then turn the vacuum right side up and put the brushes on the floor. Can you still hear the brushes spinning when they are hitting the carpet? If yes, then this is not the problem. If the brushes however are NOT spinning, this indicates either your brush roll, clutch, or belt have gone bad.

The roll brush will not turn when on floor. Too much pressure stops brush. Changed belts and still not working


Turn the belt inside out. This problem stems from a design flaw in the mechanism that turns the hoover from bare floor to carpet. After taking it apart I realized that the spring that pushes the belt tight (to make roller spin) is not any where near strong enough to keep the brush rolling. My solution was to turn the belt inside out (there by essentially shortening the belt and allowing enough pressure to be applied to the roller to keep it spinning. Horrible design flaw. I am an engineer and find this pathetic. Hope this helps someone.

Can't get the belt to engage for carpet cleaningwith my riccar


I will attempt to walk you through the belt change on your Riccar 8955 upright vacuum cleaner. I have taken pictures for you for each step to ensure that it's done properly. What you'll need to have handy for this repair;

- Phillips Head Screw Driver
- Riccar 4000 / 8000 Series Belt
- Riccar 8000 Series Roller Brush With Clutch Assembly (only if the brushes have worn down, not necessary if brushes are still long)

Step 1: Make sure the vacuum2_bing.gif cleaner is unpluged, and turn the vacuum cleaner upside down so the bottom plate is upwards. It's easiest to do on a work bench or counter top.


a83c268.jpg
Step 2: Unsrew the two metal screws on the metal bottom plate with your Phillips head screw driver, and remove the bottom plate from the vacuum cleaner so the belt is completely exposed with the roller brush.

Step 3: Remove the belt guard that sits to the left of the roller brush, and is a metal part that protects any dirt & debris from going over to the belt. Here's a picture of that part being removed;


6cb6693.jpg
Step 4: Remove the Rug / Floor actuator arm from the clutch on the right hand side of the roller brush. Simply pull the metal actuator arm to the left of the brush and out of the circle that it sits in. Here's a picture of that;


fa36553.jpg
Step 5: Once you have removed the actuator arm for the clutch, as well as the belt guard, lift staight up on the roller brush and remove the roller brush from the vacuum cleaner:


bec4491.jpg
Step 6: Once you have removed the roller brush, and the old belt from the vacuum cleaner, take one new belt and wrap it around the metal pin in the back of vacuum cleaners2_bing.gif agitator housing. Here's a picture of where that pin is located with the belt wrapped around it;


f76bd31.jpg
Step 7: Once you have the belt wrapped around the metal pin (this is the shaft to the motor that actually spins the belt), but the other end of the belt through your new roller brush;


68efbd6.jpg
Step 8: There is a specific way that the roller brush has to be inserted. If the roller brush is not put in properly, this can cause all sorts of problems including the brush not spinning, and continously having to replace belts2_bing.gif. You can see on the end cap of the roller brush (the right side where the belt rides) that there is two little teeth that protrude out of the end cap as well as an indentation on the opposite side;


96719f8.jpg
Step 9: With the roller brush inserted through the belt, posistion the two teeth facing downwards. You can see in the vacuum cleaner where the roller brush sits, a little groove down inside of the housing. These two teeth need to straddle that groove. Also make sure that the little ring, or circle that the clutch actuator arm sits into, is facing upwards completely. It should be directly on top of the two teeth. Stretch the belt using the roller brush as leverage down into the agitator housing of the vacuum cleaner, making sure that the two teeth are facing downwards straddling the little groove. After the brush is back into the vacuum cleaner, take the metal actuator arm from the rug / floor switch, and insert it back into the metal ring (or hole) on the roller brush;

837f4a1.jpg
Step 10: Replace the metal belt guard that rests to the left of the belt. You'll notice on the belt guard that there are two little 90 degree notches on both sides. These notches need to face towards the belt or to the right. Here's a picture of the belt guard being put back into place;




72dd966.jpg
Step 11: After inserting the belt guard back into the vacuum, turn the vacuum cleaner over so the top of the agitator housing is facing you. Change the the rug / floor switch from bare floors to the carpet setting, and the turn the vacuum upside again so the brush and belt are exposed:


91e54c7.jpg
Step 12: With the vacuum set to the carpet setting, pull the belt forwards to ensure that the brush is spinning freely. If the belts do not spin freely, repeat steps 2-10.

The belt is intact but the aggitator doesn't spin anymore. Had a horrible rubber smell, went to change belt. Not the problem. Anyone know what could be wrong? Dirt Devil bagless w/dirt indicator


Even though your belt is intact it still could be worn. if you tilt the vac up (roller off the floor and the roller spins, replace the belt. on most vacuums the life of the belt for optimum performance should be 9- 12 months. If your vac has a carpet / bare floor selection, check to make sure it is in carpet mode.

Eureka 4870: Brush roller turns even in hose setting.


You either have the wrong size belt, most likely too small, or you have installed a new belt incorrectly. When you open the cover on the bottom of your vac, you will see the pulley that moves as you flip the switch from floors to carpet. The belt does not go around this pulley. When activated(carpet) the pulley puts tension on the belt causing it to turn the roller. When switched back to hard floors, the belt looses tension allowing motor to cause suction but disabling roller. Also, the dial on top of vac is only to direct suction, not for disabling roller

Installing a belt


1. Unplug the vacuum
2. Take the bottom cover over the brush off by removing the 3 screws
3. Switch the brush roll control lever to bare floor
4. Take the roller brush out
5. Put the belt around the small pulley from the motor
6. As you are putting the roller brush back in put the belt around the space on the roller brush - center the belt on that space - THE BELT WILL NOT BE TIGHT BUT THAT'S NORMAL
7. Reinstall the bottom cover with the 3 screws

THE BELT DOES NOT GO AROUND THE SILVER PULLEY CONNECTED TO THE BRUSH ROLL CONTROL LEVER
