Robot vacuum does not respond to remote control or app commands, but buttons on the robot work.

Safety first: No internal work is needed for initial troubleshooting.

• 1. Check remote batteries: Replace the batteries in the SilverCrest remote control and ensure there is a clear line of sight to the robot (if IR remote).
• 2. Verify Wi‑Fi: Confirm the robot shows as online in the app. If offline, reboot your router and the robot.
• 3. Re‑pair device: Remove the robot from the SilverCrest app and add it again using the pairing procedure.
• 4. Check server status: If multiple users report issues, the SilverCrest cloud service may be temporarily unavailable; try again later.
• 5. Hardware check (advanced): If only your robot is affected and never appears online, the internal Wi‑Fi module or antenna may be faulty and require replacement.
