I'm sorry to hear you're having difficulties with your DC15 Animal. Your cleaner is equipped with a safety device which shuts off the brushbar if it gets tangled with a rug fringe, shoelace etc. After making sure the brushbar is free of threads, hair or other obstructions, you'll be able to reset the cleaner and get the brushbar running again. The easiest way to do this is to follow the steps shown in our guide:http://www.dyson.co.uk/support/help.asp?article=915&product=DC15-ANIMAL
Please note, the brushbar will never rotate when the cleaner is standing in the upright position, or if you've turned it off using the red brush control switch located next to the purple on/off switch.
By following these steps, you should be able to resolve your issue without further assistance. However, if you've tried this and are still concerned, it's probably best if you get in touch with us directly. You can call us free on 08002980298 (UK), or 1866MYDYSON (US).
