Lefant M2S Pro Robot Vacuum and Mop ,10000Pa, 240Min, Self-Emptying,190° PSD Obstacle Avoidance, dToF LiDAR Multi-Floor Mapping, APP Customized Cleaning, Carpet Detection, 5200mAh Battery

I bought a vacuum in January. By August it would no longer charge and completely died. I emailed back and forth with Lefant for about 2 weeks. I did absolutely everything they said except when they told me to pick apart glue attached to a battery wire so I could unplug and plug it back in. After they had no more solutions for me they did not send a new vacuum they instead stopped replying to my messages.
