Brushless motor configuration: Both the suction and handle motors are brushless, offering a lifespan approximately ten times longer than traditional motors, with low vibration and energy consumption for comfortable, prolonged use. Core performance parameters: Features a brushless single-drum motor with 330W maximum power and 28,000 rpm maximum speed, combined with 10kPa high vacuum and a 30L square barrel design, operating at less than 65dB for a quiet environment. Features details design: Square design increases capacity by 35%, includes noise reduction and sound insulation, a handle-type structure, and real-time temperature and speed display, with automatic thread collection in the tray to eliminate cleaning needs. Automatic thread trimmer: Suction and trimmer heads are fully integrated for automatic trimming without damaging clothing or cutting overlock or cover stitches, keeping residual thread under 1mm for optimal garment quality and timeliness. Precautions: Includes a negative pressure check valve that opens if the filter clogs or is improperly installed, preventing motor and computer board damage from overload and overheating by replenishing airflow.
