Question about Dyson DC11 All Floors Bagless Canister Cyclonic Vacuum

1 Answer

Dirt and hairs not going into cylinder

The suction on my Dyson is very powerful, but all of the dirt and hairs are getting trapped on top of the filter. I washed the old filter, but the problem continued. A replacement filter failed to solve the problem. All of the seals seem sound. Can anyone tell me how this is happening (it would seem impossible) and what I can do to rectify it?

Thanks in advance,

Pete

It's not the filter that's the problem.  Air should go first to the cyclones, then to the filter, so the filter catches only those finest dust particles that are not trapped in the cyclones.  The most likely cause of the problem is that the cyclone pack is not properly seated, with the result that at least some of the dirt-bearing air is going directly to the filter rather than passing through the cyclones first.

    Second thought...  It may also be that some internal part of the cyclone is missing. It is not unknown for seals to get lost during the emptying process. Check with your manual and make sure all the parts are present and correct.

    I've just had the same problem: very good suction but most of the dust ends up in the filter instead of stopping in the dirt bin. It turns out that I had lost a coloured piece that fits into the bottom of the bin with rubber seals on it. Easily replaced on eBay with a second hand part!

Brand new dyson DC40 has no suction at bottom


Hi Marin, it's Jack at Dyson.

DC40 is a powerful mid-size Dyson upright vacuums, and we wouldn't expect you to have any concerns about performance on hard flooring or carpet. As long as the machine is used and maintained as described in the User guide we would not anticipate a change in performance, and we're on hand to help if Dyson owners need assistance.

It's important to note that for effective pickup, the cleaner head needs to form a close seal with the floor surface. Simply placing a hand under the cleaner head does not give an accurate idea of suction as you're not creating a seal, as you would be when you place your hand right across the end of the wand or hose. If you turn on and recline the vacuum, turn off the brush bar then lower the cleaner head onto something like a sheet of newspaper, you should see the newspaper held tightly against the soleplate by the vacuum's powerful suction.

We're keen to discuss this with you, and to help ensure your DC40 is working as well as it should be. Please email your full contact details to my colleagues at askdysonUS@dyson.com, and one of our experts will be in touch as soon as possible to provide further assistance.

Dyson DC25 is barely picking up, but what it is picking up is not going into the cannister,


Your problem is posted in the wrong category, so probably no-one reading here (Telescopes and Binoculars etc) will have the solution.

No suction


check for clogs and maybe the brush roller is too caught up with hair and fabric from the carpet.

Suction is not as it used to be


take out beater bar and pop end cap off and clean out inside of beater bar.

Every time i VACUUM THE DIRT AND HAIR GET STUCK ON TOP OF THE FILTER WHICH IS LOCATED UNDERNEATH THE CANISTER//


There is a black gasket type thing that fits on the bottom of the cyclone part that is supposed to keep dirt and hair from getting down to that filter. Yours is probably missing - mine was. I called Dyson and they sent me a new cyclone for free.

No suction - Dyson vacuum


Hi If the Dyson is throwing out dirt at the back, it could be three possibilities:
1) The main floor head suction channel is blocked. Check the sole plate where the beater bar is, or if you have a cylinder/pull along model check the floor heads and main extension pipes.
2) Check all the inspection tubes especially the bottom part where the main handle hose is. Also check the filters are clean as well as the Cyclone shroud honeycombs are completely unclogged. Use of the upholstery brush is ideal for dust removal on the cyclones.
3) Check the main inspection areas on the Dyson as sometimes a back log of clogged dirt can get stuck. Also check the dust channel points when then bin is taken out.
Hope all this helps!

Obstruction in the hose?
Your vac has developed a hairball possibly.... when a piece of flexible media ie.... cardboard, plastic etc... gets lodged in the hose, and begins collecting hair & dust to the point it no longer has enough draft to pull debris from the floor.

Holes in top of dirt bin keep clogging


Make sure that your filter is clean. The holes are normally clogged.
