As high voltage is applied to the lifting mat, it takes on a negative charge and the ground plane becomes positive. Any dust present under the mat will take on a positive charge and will then be attracted to the negatively charged collection mat. A dust print that is transferred to the lifting mat will appear as a precise mirror image of the original print and lifts made from rough-surfaced floor tile or irregular flooring of any kind are facilitated using this method. 2' x 3' Lifing mats are perfect for searching large areas at one time.
