I have a ten-year-old DC26. Although I have never really used this head attachment much, preferring the simpler floor attachment, I started using the turbine head recently - exactly the same one that’s shown in the video on the Dyson webpage for this model.
However it suddenly stopped working today because of the on/off button - the grey button which blocks the air flow when pushed (again, as at the end of the video). The button now turns itself off after 5 or 10 seconds, presumably on a slight bump that loosens the button.
I was hoping to find a maintenance run-down for the turbine head to see if the thing is salvageable. Is it worth taking apart or is this a known problem?
Thanks
