Make sure you have a good bag installed in the vacuum and the door is properly in place. Remove the attachment hose from the bag chamber and turn the machine on. You should have good suction coming from the hose inlet. If you don't you have a problem in the bag chamber. Bad bag, door is not on correct, door is defective, dirty secondary filter.

Connect the hose back to the machine and pull the other end out from the bottom, and turn the machine on. You should have good suction there. If you don't you have a clog or hole in the attachment hose and it needs to be unclogged or relplaced.

Reconnect the to the bottom. Flip the mahine upside down. Take the screws out of the bottom plate and remove. Remove the brushroller and belt. Turn the machine on and you should have suction at the inlet coming off the brushhousing. It you don't, then you have a clog in the nozzle hose and it needs to be removed. It will probably be more accessable from the bottom side since that is the way that it entered.

Sometimes a suction problem can be confused with an brush problem. The belts on that machine should be replaced every 6 to 8 months because they will strentch and wear. This is an inexpensive maitainance that will dramatically improve its function. Part Numbers are 38528-035 and 38528-034

Riccar 8995 no suction


I think you mean it's an 8955, Riccar has not had a 8995 model. If there is no suction in the hose it has to have something clogging it. Open the little round opening on the back of the vacuum where the hose attaches to see if you have suction there.

Hi there,

Sorry to hear you're having difficulties with your DC28. If it doesn't seem to be picking up as well as usual, it's possible that there's a blockage in the system, and you may need to give the filters a wash. The easiest way to check for and remove any blockages is to follow the steps shown in our online support guide:

http://www.dyson.com/support/help.asp?article=1231&product=DC28-ANIMAL

The correct way to wash the filters is shown in the video below. Under normal use, this should be done at least once every 3-6 months. Use cold water without any detergents, and ensure the filters are totally dry before replacing them - this may take up to 24 hours.

http://www.dyson.com/support/help.asp?article=1456&product=DC28-ANIMAL

Hopefully, by clearing any obstructions and washing the filters, you should be able to resolve your issue without further assistance. However, if you've tried this and are still concerned, it's probably best if you get in touch with us directly. One of our experts will be happy to run through some troubleshooting over the phone with you recommend the best course of action.

I've bought a dyson dc07 upright vacuum and need to know how to get suction through the hose as opposed to the main machine.


Hi there,

When the cleaner is standing in the upright position, it's engineered to divert suction automatically from the cleaner head to the hose. The correct way to use the hose, wand and dusting tools is shown in the user guide:

http://media.dyson.com/downloads/us/floorcare/manuals/dc07_opmanual_usa.pdf

If there doesn't seem to be any suction coming through the hose when the cleaner is standing upright, you may need to check the machine for blockages. The easiest way to do this is to follow the steps shown in our online support guide:

http://www.dyson.com/support/help.asp?article=4&product=DC07-SY-HEPA_US

It's also a good idea to give the filter a wash, as demonstrated in the video below. Under normal use, this should be done at least once every 3-6 months. Use cold water without any detergents, and always make sure the filter is totally dry before replacing it - this may take up to 24 hours.

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).

Very little suction in hose no tears in hose


Hi there, SmartAlec from NelsonVacuums.com.au . I have fixed hundreds of Dyson DC07 vacuum cleaners over the last few years and i would say there are 2 possible causes for the loss of suction.
1st is that the filter looks clean but is actually worn anyway. The way to tell is remove the washable filter from your vacuum cleaner. Take out the foam insert this seems to last longer that the other part. Hold up the plastic cage to the light and look at the white part (well it used to be white anyway) you should be able to see light through it. If you cant see through it you need to replace it. Here is a link to that filter for purchase . To verify this is the problem just run the vacuum without the filter in you should see an improvement - note do not actually **** up material the filter is there for a good reason.
2nd problem is that you have a blockage in your radix assembly. If you take off the whole dirt bin and feel the suction on the upright part where the chamber joins the vacuum (basically bypassing the radix) if there is good suction here you will either need to replace the cyclone top or dismantle and clean it. (it is very difficult to clean as it doesn't completely dissassemble)
Hope this helps - If you want more help send me a message
HAPPY VACUUMING ! :)

Very little suction? Someone give me an answer please.


You must have something obstructing the airflow. There is sometimes a small trap door under the vacuum where the brush is located. Open that door and see if there is something jammed in it. If you don't have the door, then there is an obstruction somewhere in the vacuum. You should also look in the hose.

No suction


have u checked all of the filters. I know that when not all the filters r clean the machine will turn on but then it will sound louder and still have no suction. Most times there is a filter under dirt container thats sits above motor and if this filter is not clean the motor cannot breath. Thus no suction
