Dirty filters on DC24 - easy to wash clean and dry by radiator for 24 hours |

Do you use carpet fresh or suck up fine powder for some other reason? I ask that because it's apparent that even large debris are not being thrown from the airstream. The physics of a Dyson are really fascinating. Lowering the airflow in a system like that starts a positive feedback system whereby particles increasingly escape the system and hit the filter, thus further reducing airflow, thus further decreasing the removal of particles by the cyclones, and so on. Your puzzle here is a "chicken or the egg" quandry, but my first guess is that something got sucked up that lowered the airflow and led to the situation shown in your photos. Or did the machine tip over? |

Can you think of any circumstance that would cause moisture to get into the machine, such as damp carpets or wet debris? I bet that would reduce airflow either internally by obstructing the shroud or inner passages or clogging the filter. I think you could test this by applying an airflow meter to your machine and to a brand new machine as a baseline. If airflow is reduced, I think you have your answer. If it isn't, then my hypothesis is incorrect. |

Hmmm... I have the odd hair or two make it to the filter but nothing that significant. |

I wasn't suggesting that moisture was anything other than a potential occult perpetrator of reduced airflow. I have ten Dysons in my collection. I've never had the problems you have. I've credited my good care of the machines, frequent checking of the pre-filters, and never using anything that would likely get through the cyclones to the filter such as carpet powders or moisture with this. I've helped lots of friends with their Dysons that have clogged pre-filters. All of them (not enough to be more than anecdotal) have either gotten wet or sucked up carpet fresh. The one time I got a lot of dirt on a pre-filter in one machine was when I let someone borrow my DC07 Carpet, and she sucked up carpet powder in it. It wasn't the same until I disassembled it and blew the cyclone assembly out with an air compressor. Meanwhile, the pre-filter repeatedly collected a lot of dust. |
