Hello, thank you for providing a review. We apologize for the inconvenience caused as you are facing a run-time issue with the machine. We can imagine how frustrating and disappointing this must be for you. This does not fall in line with the iconic service standards we aim to provide our customers. However, we strive to provide the best experience for our customers. Please be informed that the overall run time can increase and decrease depending on the power mode and tool being used. Dyson V8 gives 40 minutes run time on ‘Powerful’ mode and 7 minutes on ‘Max’ mode. Rest assured, we are committed to assisting you. We would also like to look further into this for you. For detailed information, please feel free to email us at askdysonUS@dyson.com and include ‘Dyson Review’ in the subject line for prompt attention to this matter.
