Integrated thread suction and cutting head keeps residual threads within 1mm, ensuring clean cuts. Cut threads are automatically collected in the cutting tray, leaving no residue on garments and eliminating extra cleanup. Precise trimming outperforms manual work by not cutting clothes, overlock seams, or stretch seams. It creates perfect thread trimming effects, ensures finished garment quality, and reduces production time and costs. Innovative square design increases capacity by 35% compared to older models. Features all-round noise reduction and sound insulation for a quieter workspace, plus a handle for easy installation and use. Brushless motors in both vacuum and handheld units offer about ten times longer lifespan than traditional motors. They produce less vibration, preventing hand discomfort even with prolonged use, and consume low energy. Protection mechanism: when filter is clogged or installed incorrectly, a negative pressure check valve opens to supplement airflow, preventing motor and circuit board damage from overload or overheating.
