Graviton Robot Vacuum Main Brush Gear HCDM2289 for Neato D75 80 85 D3–D8

Neato D75, D80, D85 & D3–D8 Main Brush Gear

This replacement main brush gear fits Neato robot vacuums including the D75, D80, D85 and D3 through D8 models. It restores the brush drive when the original gear is worn, stripped or missing. The part is made from a durable material designed for a long service life. Accurate dimensions allow straightforward installation without modification.

Check your Neato model before ordering

Confirm that your robot vacuum is one of the listed Neato D75, D80, D85 or D3 to D8 units. The gear is specific to the main brush module and will not fit other brush assemblies or brands. Verify the existing gear is the source of the noise or drive loss before replacing it. No tools beyond a small screwdriver are typically required for the swap.

Low friction design keeps motor load light

The gear meshes smoothly with the motor pinion, so the brush motor runs at normal current draw. Operation stays quiet because the tooth profile matches the original specification. No extra lubrication is needed and the material resists wear under daily cleaning cycles. Power consumption and thermal load remain unchanged from the factory part.
