Either the wind suction tunnels on top of the clear cannisters need to be cleaned out or the round foam filter between the bottom if the cannisters and the part with the roller bar is clogged.

SOURCE: dyson blowing top of cyclone air release valve.
It sounds like the same problem I was having. I had loss of suction through he hose then all of the air was coming out through the vent/valve on top of canister. If you are looking at your dyson from the back, look at the bottom. You will see a purple plastic tab on the bottom left. That allows you to remove the plastic u-shaped hose that goes from the hose to the bottom of the dyson. I just removed that and found it was completley blocked. I removed it and the dyson has no loss of suction orair through top valve/vent. I hope this helps. I never post but i'm just excited that I got my dyson working perfectly again.

Hi.
Try cleaning out the vortex this will sort out poor suction.

SOURCE: dyson suction loss
make sure the filters in the bottom are clean, then remove the canister and you will need to clean it thouroughly, pay close attention to the upper section inside where the "cones" come togetheri have read that they are prone to clog up here and lose suction, google dyson suction loss or how to clean a dyson ect...pay attention to getting the rod that releases the bottom to dump back in the correct place or it will not work right. a few write ups tell about this!

Hi its Darran at Dyson.
It would be worth checking that the brush bar is turning when the machine is in the vacuuming position. If it is not turning, please press the re-set switch located on the cleanerhead.
If this starts the brush bar turning but does not solve the problem, please check the cleanerhead for blockages and remobve any threads or hair trapped around the brush bar.
Shoudl you need any further help or advice, please contact our Helpline on 1866MYDYSON.
Kind regards
Darran
