Bought Tineco Pure One S12EX in early 2022, about a month before the waranty expired it has issue where when using full stand the roller having trouble rolling as if power cut off intermittence. Reported to Tineco for warranty a little late as I need to go for outstation and they quoted RM180 to replace the pole or whatever you call it.

Ended up I open it up, trace the issue to be corroded pins. Using sand paper to polish the pins and it worked like new again.

Anyway, just avoid Tineco.
