So my cleaner stopped working at the 11th month of a 1 year warranty. Emailed Vevor and they immediately replied and connected me up to the Chinese manufacturer. They said send a video showing what's up. I did. They very quickly asked if I could pull the bottom off and look at the circuit board and take a pic. They sent a video of how to disassemble. I looked and saw a resistor was damaged. Sent a pic. They said send a pic of the part number on the board. They said a new board is on its way shortly. 2 days later they send tracking number. 2 days later at 9:30am DSL delivers it, from China. It looks updated with a fan on it. Popped it in and bingo, all good. Wow!
