The vacuum intermittently loses connection to the smart app or Wi-Fi features (if the model supports it).

Safety first: This is a low-voltage communication issue; no special electrical safety beyond normal appliance use is required.

• Improve Wi-Fi signal: Move the charging dock closer to your router or use a Wi-Fi extender.
• Reboot router and dock: Power cycle your router and unplug the dock for 1 minute, then reconnect.
• Re-pair device: In the Levoit app, remove the vacuum and add it again following the pairing instructions.
• Check for firmware updates: Update the vacuum’s firmware via the app if available.
• If connectivity remains unstable: The Wi-Fi module on the dock or vacuum PCB may be faulty and require replacement.
