ECO Mode
When the ECO mode button is pressed, the control signal is transmitted to Control board (EB2) via port J1-5 (Brush
PWM) and J1-6 (Vacuum PWM) to control the output of brush motor (M1) and vacuum motor (M2). And the brush
and vacuum output MOSFET of Control board (EB2) will lower the voltage of brush motor and vacuum motor to
about 18.5V via PWM regulation, reducing the current draw of brush motor and vacuum motor to reduce power
consumption and thus achieve energy saving.
