Roborock robot vacuum only supports 2.4G WiFi. However,since most routers support both have 2.4G and 5G, in order to ensure the machine's stability, it is recommended to switch to 2.4G WiFi when using the robot by following the instructions of your router setup. 7-Weeks of Hands-Free Cleaning: The Auto-Empty Dock Pure empties the robot automatically after cleanup, so you don’t have to do it manually or frequently. With its 2.5L dust bag it stores up to seven weeks of debris. Perfect gifts for families and friends.
