Abstract
A rechargeable vacuum cleaner comprises a main body, at least two sets of rechargeable batteries for driving a motor in the main body and a power-supply control unit. The power-supply control unit is coupled with the sets of rechargeable batteries and the motor for affecting a set of rechargeable batteries of higher voltage to supply power to the motor and for preventing the set of rechargeable batteries charging another set of rechargeable batteries of lower voltage. The power-supply control unit includes a silicon assembly (being a bridge rectifier) or a diode. The rechargeable vacuum cleaner can be of two piece type (with a detachable unit) or a two piece type. Therefore, the rechargeable vacuum cleaner can lengthen the operating time and prevent damaging the batteries.
