A:Answer Hi Charlotte, We're sorry to hear you are experiencing issues with your Curise, and want to help. When plugging the charger into the unit make sure your vacuum is switched off. If not, it will turn on when plugging the charger in. If this is not the simple fix, please reach out to our Cordless Customer Service team at 1-888-679-2121, or message us on Facebook. We hope this helps. - Jenna
