In Brabham, Perth, Lachie Perrem, 25, suffered burns to about 75% of his body when a robot vacuum exploded after a leaking lithium-ion battery ignited while he cooked, destroying his home and prompting investigations into the device. His mother, Fiona Perrem, has shared new details of the incident and says he’s waking from an induced coma and making progress after multiple surgeries, with a GoFundMe raising over $40,000 to help with medical and living costs.
