Dyson animal, have to hold ON switch for it to work
Pull the wand out of the Vac. Need to use a small Torx bit to take out 2 screws hidden behind the wand storage. Once screws are out, there are 4 push-clips which need to be un-latched. Pry the power panel off and you will expose the two switches (one for power, one for the brushes). Push the power switch down and it should "release" and go back to clicking when pushed. Re-assemble. Took about 5 minutes to fix.
