My daughter’s Dyson also shuts down After a few seconds, but nothing to do with battery or contacts of it, but the button on the handle is broken inside the handheld. Tried to put it apart, but quite difficult. Question at DYSON, why don’t you release your technical information for this website for instance. We WANT the right to repair,this means : Fred technical information, repair manual and affordable spare parts. When so, we will promote Dyson as a sustainable company. If not, at everyone : buy something else ! And one day , I hope soon, manufacturer will be forced to do it. Let’s promote sustainable index for consumergoods as soon as possible.
