Hi @Tim481975,
Welcome to the Dyson Community!
An unusual odour could occasionally occur as your machine’s carbon filter works to absorb environmental odours including pets, furniture, newly renovated houses, or a humid home.
If you continue to use your machine as normal, we would expect the smell to subside within 1-2 days. However, in some cases this may take a little longer.
If the odour persists, please visit Dyson.com and click the round purple button to launch the Dyson Digital Assistant. Then click the agent icon in the bottom left corner of the chat window to start a conversation with our Customer Care team. Our experts will be happy to take some further details and discuss your options.
Hope this helps!
