These reinforced belts fit the Panasonic power nozzles that use a cog type belt. This design provides positive power transfer from the motor to the brush roll. It can not stretch and slip. This package contains two belts even though each typically lasts three to five years. For Panasonic canister models MC-V9620, MC-V9634, MC-V9635, MC-V9644 and MC-V9647.

This belt also fits many Kenmore (Sears), Hayden and Royal power nozzles which are made by Panasonic. These power nozzles are sometimes refered to as "Whirlpool power nozzles" since they originally designed and manufactured them.
