Another time, I had a power supply unit that was - apparently - overheating. Quite an accomplishment in the Finnish conditions! I reported this to Worx Support within my original 3-year warranty, and even though there was a bit of back-and-forth (and I actually ended up ghosting them for 6 months because the power supply MOSTLY worked), they eventually decided to send me a new charger for free. I've written about this case here before: https://www.koskila.net/frequently-asked-robot-lawn-mower-questions/#faq-question-1656256829995 Much appreciated.
