Welcome to the Bunnings Workshop community @Hawkfan. It's fantastic to have you join us and many thanks for your feedback.
Your experience with the Ryobi One+ 18V Cordless Blower Vac doesn’t sound typical. I have discussed it with the Ryobi team and they would encourage you to return it to the store of purchase to be assessed. The team in-store would be more than happy to assist you with locating your proof of purchase.
Could you please reply to my private message on the additional details of your purchase?
