Brand new pure i9 robot vacuum has error code E21 and red battery symbol.

Has been on charge for a couple of days and tried to connect to the app but now has this error code.

  • Try taking them out and plugging them back in. Maybe they are poorly seated.

  • Yeah I tried that but same problem, I have now returned it to the store for a replacement, they tested it also and same problem. It was a battery malfunction.
