Roidmi Eve Plus Battery Issues - Expensive Repairs After Limited Use

I bought a Roidmi Eve Plus robot vacuum 2.5 years ago. Less than a year later, it malfunctioned, and I was told it was a battery issue. After getting it back from service, I used it for about a month, but then an earthquake occurred, and I couldn't live in my home for an extended period. When I finally returned and tried to use the robot again, it didn't work. The service center now tells me it's another battery issue, and since the warranty has expired, it will cost ₺6,000 to repair. My money feels wasted, as I couldn't even use the vacuum for a full year.
