Firmware update failed?

Whether you're using a robot vacuum or a H14 / H15 series wet dry vacuum — if you've run into a firmware update failure, or the update gets stuck, please run through these quick checks first:



1. Check the battery level
• Make sure the robot is charged to at least 15%. If the battery is too low, the firmware won’t be able to update properly.

2. Check the Wi‑Fi signal
• Make sure the robot is in an area with a strong and stable Wi‑Fi signal. Weak or unstable signals can cause the firmware download to time out and fail.
.
3. Try the update again
• Once the battery is sufficient and the Wi‑Fi signal is stable, try upgrading the firmware through the APP again.
• If you see any new error messages, take a screenshot — they’ll be helpful for troubleshooting later.


If the issue still isn't resolved after checking these:
Please contact our customer service, or DM us here with your UID and SN. Our technical team can check your device remotely and push the update directly from the backend if needed.
