• 1.After cleaning is completed, the device automatically enters sleep mode, cutting off power supply to the main brush motor and retaining only a micro-power wake-up channel, which reduces standby power consumption to the milliwatt level. The soft-start technology is adopted to gradually boost the voltage during startup, avoiding current surges that may damage the motor and battery, thus extending the device’s battery life and service lifespan.
• 2.Built-in high-efficiency DC-DC step-down chips accurately convert the battery voltage range into the operating voltage required for the motor, Hall sensor, and control chip. With low output ripple, it prevents motor jitter and prolongs the service life of the device.
• 3.Integrated with four major protection mechanisms: overcurrent, overheating, short circuit, and motor lock protection. Equipped with a PPTC self-recovery fuse, it can limit the current within milliseconds when the main brush is jammed, and automatically resets after the foreign object is removed without manual intervention. It effectively solves the pain point of "motor burnout caused by brush jamming" and improves product durability.
• 4.It collects operating data through current-sensing resistors and temperature sensors, and transmits the data back to the main control chip in real time, supporting the display of main brush status (rotational speed/load/temperature) on the APP. Once an abnormality (such as motor lock or overheating) is detected, it immediately triggers shutdown protection and sends an alert to ensure safe usage.
