The Dirt Devil Cogged Belt – Vision (RY912427) is a precision-engineered replacement belt designed for upright vacuums in the Dirt Devil “Vision” series. This cogged (ribbed) belt transfers motor power to the brush roll with improved grip, ensuring the brush spins at the correct speed for deep cleaning. When your vacuum’s brush stops rotating or cleaning performance drops, this belt is the direct part you need.

Manufactured from high-quality rubber composite with reinforced tensile cord, this cogged belt offers better flexibility and durability compared to plain flat belts. The ribbed (cog) design reduces slippage and heat buildup, maintaining consistent tension under load. Its precise dimensions and tooth profile match OEM specifications to ensure reliable operation.

This belt is compatible with a variety of Dirt Devil Vision upright vacuums that originally used the RY912427 (also known as RO-912427) cog belt. Installation is straightforward: remove the old belt, route this cogged belt onto the motor and brush roll pulleys, then reassemble the vacuum. With correct installation, users will notice restored brush roll spin, improved edge-to-edge cleaning, and enhanced suction recovery on thick pile carpets.

It’s perfect for scheduled maintenance cycles or restoring performance in used/vintage units. Technicians and DIYers alike will use this belt to bring worn machines back to OEM-level cleaning performance.
