Could be bearings and or brushes. For me it sounds like it could be leaning more to bearings. Don't quote me on that, I'm no expert. | ||

Rattling/grinding noise in the hose mode
I am having a similar noise issue in the hose mode with my Ultimate G Diamond. For me, I believe there is a loose bushing for the headlight hood. When I hold the headlight hood down while in operation, the noise stops. Soon after letting go, the rattling noise starts again. I'm thinking it's the plastic bushing, maybe it has worn out or loosened somehow. Have you tried holding down (or completely flipping open) the headlight while in hose mode to see if this changes the sound? Hope this helps...

What you are describing is exactly what I'm experiencing. When I use my Ultimate G Diamond in upright mode, that vibration noise does not happen. It only happens in canister mode (with the hose). Pressure applied to the headlight while vacuuming in canister mode stops the vibrations. Also, flipping open the headlight hood all the way, while vacuuming in canister mode, sometimes prevents the sound from happening.
Kirby motors kick into a higher speed while being used in the canister mode to improve suction through the hose. This must be the culprit! Has this helped you locate the source of your noise? | ||
