My old DC 24 no longer works. The motor was running but I could see that the brush head was not spinning, causing the roller to brake rather than clean thoroughly. Pressing the red reset button didn't help. After much research I found out that the head has its own motor and can die by itself. I went to a few stores but couldn't find anything I liked as much, including the new Dysons that are too big for my closet. I got lucky with my research and found out that I can always buy a new head set for this old DC 24! Expensive but worth it and a lot less than a new car. Easy install even for this old lady and works great again. Old off, new on. Note: There is no reset button on the new build, but I understand it reboots after every shutdown.
