A tradesman in Australia is reportedly in critical condition following an explosion caused by his robot vacuum cleaner. The incident, which occurred in his kitchen, has left him with severe injuries, necessitating multiple surgeries, including skin grafts. His mother has shared details about the explosion, indicating that it was triggered while he was cooking. The device has been sent for investigation to the state's building and energy office. Experts have noted that lithium-ion batteries can fail and cause thermal runaway, leading to violent explosions. While there have been previous incidents involving vacuum cleaners, this is the first reported case involving a robot vacuum. The report has limited confirmation from reliable sources, and further investigation is ongoing to understand the circumstances surrounding the explosion and the safety of such devices.
