Simply slide frame connector into the telescopic handle and it locks into place with an easy-to-open push button. Frames have hook and loop strips which can be used with wet or dry microfiber pads. Frame swivels to provide full 360º range of motion, or can be locked in place. 16 and 22 inch sizes are available in the new and improved smooth surface aluminum frame, which prevents moisture, debris, and dirt collection in the frame. In addition, the velcro strips are channel _t, and therefore replaceable. 36 inch frame has grooves to increase its rigidity for smoother cleaning.
