    摘要: A battery-powered cleaning implement for cleaning a target surface by using at least one of a motor-driven beater bar or motor-driven vacuum fan. The cleaning implement has a cutoff voltage below which the beater bar and/or said fan is/are no longer operable to clean. The cleaning implement has a control which reduces voltage provided by the battery/ies to the motor before the cutoff voltage is reached. The reduction in voltage provided to the beater bar and/or fan vacuum reduces the rotational velocity, providing an audible signal to a user that said voltage provided to said motor is being depleted.
