Your sweeper may have overheated. I don't know what brand you have but I hope you weren't trying to vacuum pine needles from the Christmas tree. Pine needles are sticky and will clog up any vacuum sweeper. Check your sweeper to make sure the tubes (hose & pipes that carry dirt) are clean and clear. I used to service Oreck vacuum sweepers.
