Flex XC3401VRG-25 Dual-Action Polisher W/ 25 FT Power Cord Pads do not rotate, they oscillate, or jiggle, in a random pattern designed to simulate hand application. The bale-style handle which puts your hands at the 6 o'clock and 12 o'clock position which most professionals prefer. Very solid "feel", like it could operate all day without stopping! Seven function microprocessor to ensure consistent speed. Auto shut-off carbon brushes automatically shut off the motor when they wear down to prevent damage.
