Advolution™ 20 and 20XP cord electric burnishers are designed to maximize performance, productivity, and operator ease. Both models feature the unique Flex Floor™ Technology, enabling the motor to pivot and hug floor contours. Advolution also utilizes a patented gas spring technology that precisely regulates the head pressure for a maximum shine on hard floor surfaces. This exclusive patent also enables the machine to be smaller and more maneuverable.
