Supported 3irobotix Devices

Shenzhen 3irobotix Co.,Ltd. produces white-label vacuum robots. They are sold under various brands. For example Cecotec Conga or Viomi. Since they are basically the same products, hopefully, Valetudo will eventually support all of them.

For now however, there’s only experimental support for the Viomi-branded ones which run a customized firmware including a miio interface.
