A robotic vacuum cleaner caught fire and burned down a house in Perth, leaving a 25-year-old man with severe burns across most of his body. It's the first time fire investigators in Western Australia have recorded an incident like this The Guardian.

Lachie Perrem, a technician, was in his kitchen in Brabham on Thursday, 2 July 2026 when the vacuum suddenly malfunctioned and ignited. Emergency crews arrived at 5pm and needed more than two hours to put out the fire news.com.au. Perrem suffered burns to about 75% of his body and was treated at Fiona Stanley Hospital. Another person was also injured. His fiancée and others living in the house lost their home 7NEWS.

Fire investigators determined the vacuum malfunctioned by accident. Now they are trying to figure out what exactly went wrong — either a problem with the battery or a problem with the electrical wiring. This matters because different types of faults are handled differently by safety regulators and can lead to different product recalls.

Robot vacuums have a battery inside them called a lithium-ion battery. These batteries have caught fire before in other devices like electric scooters and power tools. What makes this case unusual is the type of product. Robot vacuums usually sit plugged in and charging for many hours — often overnight or while people are away from home. That's the worst time for a fault to occur, because no one is around to stop the fire before it spreads. The fire started in the kitchen, which suggests the vacuum may have been running rather than just sitting idle while charging.

When investigators figure out what caused the fault, their findings could matter to robot vacuum owners everywhere. If it was a problem with the battery itself, they may need to recall the specific model or make robot vacuums safer overall. If it was a wiring problem, it points to a manufacturing mistake that might affect how other similar devices are made. Either way, safety regulators and insurance companies around the world will be paying attention, since millions of people now use robot vacuums in their homes.

Perrem's mother started a fundraising campaign on Saturday to help with medical costs and help the family rebuild. By Tuesday evening, it had raised more than $26,000.

This incident is unusual because robot vacuums are such common household items that we generally trust to work safely. The fact that one has now caused a serious fire is a reminder that even everyday appliances can sometimes fail in dangerous ways.
