    • A cleaning system comprising a rotor; an agitator; a rechargeable battery having a housing and at least two cells within the housing; a suction motor receiving power from the rechargeable battery, the suction motor coupled to the rotor; a brush motor receiving power from the rechargeable battery, the brush motor coupled to the agitator; a user-controlled switch configured to generate a user-activated signal in response to user manipulation; and a controller. The controller configured to output a first pulse-width modulated signal at a first duty cycle to control the suction motor, output a second pulse-width modulated signal at a second duty cycle to control the brush motor at a first speed, receive the user-activated signal, and upon receiving the user-activated signal, output the second pulse-width modulated signal at a third duty cycle to control the brush motor at a second speed.
    • 一种清洁系统,包括转子; 搅拌器 可充电电池,其具有外壳和壳体内的至少两个电池; 从所述可再充电电池接收电力的抽吸马达,所述抽吸马达联接到所述转子; 从所述可再充电电池接收电力的刷马达,所述刷马达耦合到所述搅拌器; 被配置为响应于用户操纵而产生用户激活信号的用户控制开关; 和控制器。 所述控制器被配置为以第一占空比输出第一脉冲宽度调制信号以控制所述抽吸马达,以第二占空比输出第二脉冲宽度调制信号,以一速度控制所述刷马达, 并且在接收到用户激活的信号时,以第三占空比输出第二脉冲宽度调制信号,以第二速度控制刷马达。
