Wyze robot vacuum displays C7 and stops; often associated with fan or suction issues.

Safety first: Turn off the robot and remove it from the dock. Remove the dustbin before working on the suction path.

• Empty and clean dustbin: Remove the dustbin and empty it completely. Clean the bin and filter area with a dry brush. Do not wash HEPA filters unless the manual explicitly allows it.
• Check suction inlet: Inspect the opening where the dustbin connects to the robot. Remove any clogs or packed dust using a small brush or compressed air.
• Inspect filter: A heavily clogged filter can overload the fan. Tap the filter gently to remove dust or replace it if it is very dirty or damaged.
• Test suction: Reinstall the dustbin, power on the robot, and start a cleaning cycle. Listen for the fan motor; it should spin up smoothly.
• If C7 remains or fan is silent: The vacuum fan motor or its wiring may have failed. Accessing the fan typically requires removing the top cover and internal panels. This is an advanced repair; contact Wyze support for service or replacement options.
