Manual electrostatic vacuum / Manual electrostatic vacuum

Triboelectrification is a common phenomenon, and maybe too common to not be neglected. It is based on a simple theory that static attracts objects that we designed this revolutionary Manual Electrostatic Vacuum. The working process is easy: rub the vacuum repetitively so the friction between the plastic ring and the nylon fabric in the front of the vacuum produces static electricity. It’s safe and environmental-friendly.
