This frame was designed to be the centerpiece for the Vac-Sweep 280 model cleaners making it very important to the cleaning process. This frame is the center housing unit to which all the parts for the cleaner are attached. The part was also designed to be lightweight preventing it from bogging down the cleaner and giving it better maneuverability around your pool. This frame is white and has one opening in which the vacuum tube can be fitted. This is the unit that gives the cleaner the power to suck and pull up dirt, debris, and other forms of mulch off your pools surface, while then dispersing this debris into the all-purpose zippered bag for disposal.
