Product Description

This is the original Dyson DC40 cleaner head assembly (part number 92364401), the complete motorized brush roll unit that sits at the base of your DC40 upright vacuum. It includes the brush roll, motor, and supporting components necessary for deep carpet cleaning. This is a genuine OEM Dyson part designed to restore full cleaning performance to DC40 models.

The cleaner head assembly is precision-engineered for the DC40 and is not interchangeable with other DC series models like the DC65 or DC33, or cordless V series vacuums. Dyson brush rolls are model-specific and designed to work with the exact motor speed and power delivery of each machine.

DC40 Compatibility: This assembly is engineered exclusively for Dyson DC40 upright cleaners. The DC40 is Dyson's mid-range corded upright, positioned between the DC33 and DC65 in the DC series lineup. Part 92364401 is the factory-original replacement.
