A:Answer Hi Slick! The Pro Power takes a genuine Dirt Devil style 15 belt. It is available online using part number 1SN0220001. To replace the belt: Turn your vacuum over. Use a Phillips screwdriver to take off the 6 screws. Remove the bottom plate. Next, Slip belt around the brushroll in area without bristles and metal pin. Each end of the brushroll will fit into pockets on each side of the nozzle. Put the plate back on and screw together. Hope this helps! ~Kenya, Dirt Devil Customer Care
