I have a Dyson v/6 and the nozzle does not engage like it should, the duster did not come as pictured just a long hose, will never buy again.
Pros
For these vacuums it is recommended that new Dyson crevice nozzles be cleaned every 2-3 months. And please remember that after rinsing, the filter is completely dry before you put it back in the vacuum cleaner.
