Battery-powered cordless cleaning system
First Claim
1. A cleaning system comprising:
- a rotor;
an agitator;
a rechargeable battery;
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 configured tooutput 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 in a first direction,receive the user-activated signal,upon receiving the user-activated signal, maintain output of the first pulse-width modulated signal at the first duty cycle while outputting the second pulse-width modulated signal at a third duty cycle to control the brush motor at a second speed in the first direction, wherein the second duty cycle and the third duty cycle are different; and
and indicator indicating that the brush motor is operating at least one selected from the group consisting of the first speed and second speed.

Abstract
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.
