Our old Dyson still worked but the power button had to be pressed by hand which is a bit tricky when cleaning. After speaking to a Dyson employee she said it was too old to replace and that they no longer make our particular model but would be happy to offer a 20% discount on a few other models (oh my god thanks but those models were both wireless and nothing compared to what I had). My husband took it apart, we ordered a tank switch and it was the perfect fix for about $7!
