Broken wheel

This is a Gen 5 Outsize Absolute with approximately three months of use.

This is the third time that I’ve had this happen. Previous instances were with a V7 and V11. Ironically, the V11 was replaced under warranty for this same issue.

I called Dyson Customer Service and was informed that the brush head is on back order.

What is the root cause of this failure? Is it a poor design or are these parts truly prone to failing this soon?
