Hello,

There are several things that this could be. Probably the most common problem that we see when customers come in with this problem is actually a fairly simple problem to fix. Here are just a few things that this could be.

The fist possible problem is a VERY common problem actually.

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 clean 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:

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

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 wheri don't seem to get suction on the bare floor mode - 54cb5e5.jpgusually cracks:

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.

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 i don't seem to get suction on the bare floor mode - 8b33cd4.jpg. Simply remove the suction port coversi don't seem to get suction on the bare floor mode - be63721.jpg these locations:

If you are getting suction power from the hose, but the vacuum still doesn't pick up on the floors, I think that these solutions should fix your problem. If you just replaced the clutch mechanism, the roller brush should be fine, but turn the vacuum over on it's side and make sure that the roller brush is actually spinning while it's on carpet mode. If none of these problems fixed your Dyson, please use the Clarification Request, or leave another comment here on the Fixya repair page, and I'll be happy to further diagnosis the vacuum cleaner with you.

We too were experiencing loss of suction with our Dyson DC07. After several failed attempts to diagnose and repair it myself, I finally gave in and took it to a vacuum specialty store. They immediately noticed that the bottom gasket to an internal component, the one with all the tiny holes in it, was missing. Though uncommon, they believe that it may have fallen off while emptying the canister and shaking dust out of the holes, simply falling into the trash barrel unnoticed. Since the gasket was not in place, further issues ensued. The filter(s) became excessively clogged, the upper housing was full of lint that was never intended to get there, and the motor would overheat. I was unable to find the gasket advertised on the Dyson sight but they do have an 800 number listed on the housing. Ordering it directly might save you a service charge.

Inspect the bottom lip to see if your gasket is still in place once you remove it from the clear housing.

Good luck

Mt dyson has too much suction


Hi there, it's Jack at Dyson.

Eureka Optima Lightweight suction weak on bare floor, hose only works when dial is turn to floor?


I think it is normal. My favorite setting is the dial is turned to bare floor. If you set your vacuum to hose, then you need to adjust the height (do not set the dial to the bare floor).

Hi there,

I'm sorry to hear you're having difficulty using your DC24 on this particular flooring. The cleaner head is designed to adjust automatically to suit the surface being cleaned, and the cleaner's powerful suction causes the soleplate to seal closely with the flooring for high pick-up of dirt and debris. You may find on certain floor types that this makes the cleaner feel a little heavy to push.

Reassuringly, it sounds as if your cleaner is working correctly - however, if you wish to discuss your issue further with one of our experts, please get in touch with us directly. You can call us free on 08002980298 (UK), or 1866MYDYSON (US).

Kind regards,

When the vacum is set on the bare floor mode, the on/off light blinks and the roller brushes stop working


This is normal. The roller brushes aren't needes on bare floors. They are used to brush lint, hair, etc. from the carpet that the suction itself wouldn't get.

959bd34.jpg This is the entire assembly that you would need to replace. According to the technician that serviced mine, DC18 is prone to fail in this area due to owner's use or abuse in my case (LOL). He said forcing the handle to stand upright after you finished vacuuming puts a stress on the plastic hook that rotates the valve from floor mode to wand mode. The trick there is when you replace the handle to upright, you have to step down on the wheel to the floor. It cost me $70 to have it replace. Since I still have it on warranty, only the labor is no charge. The damage on my machine I admitted is not workmanship or material defect but improper use of the machine. I hope this helps. Just beware of some Dyson Authorized Service Center that wheel and deal you for something like, the carpet fresh powder caused your machine to clogged and blah blah. You will know if the problem they tell you is not even close to the ones I discussed.

Vacuum not picking up dirt


The neck in your power head is likely clogged. Disconnect from the wand and look inside. Also check the wand.Since you have suction on the bare floor the hose is likely not blocked.
