2-in-1 thread trimmer: The integrated design of thread suction and cutting head keeps residual thread within 1mm for excellent cutting, leaving no residue on garments and automatically collecting all threads in the tray. Precise thread trimming: Offers great advantages over manual work, ensuring it does not cut clothes, overlock seams, or stretch seams, creating a perfect trimming effect for finished garments and reducing efficiency and cost. Innovative design: Features an original square design with 35% increased capacity, all-round noise reduction and sound insulation for a quieter environment, handle structure for convenient use, and real-time temperature/speed display for clear data and accurate speed regulation. Brushless motor: Utilizes brushless motors for both vacuum cleaner and handheld components, with a lifespan approximately ten times that of traditional motors, less vibration to prevent hand soreness, and low energy consumption. Protection mechanism: Includes a negative pressure check valve that opens when the filter is clogged or installed incorrectly, supplementing air flow to prevent damage to the motor and computer board from overload and overheating.
