BATTERY-POWERED CORDLESS CLEANING SYSTEM |
摘要 |
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. |
