If the Xiaomi Truclean W10 Ultra Wet Dry Vacuum doesn't work, please refer to the following steps to troubleshoot the issue:
1. Check if the battery level is sufficient, please use the vacuum after a full charge;
2. The battery has an overheating protection mechanism and check if the vacuum has enabled this feature. Please let the battery temperature cool down and try it again;
3. Make sure all components of the vacuum including the clean water tank, dirty water tank, and roller brushbar are properly assembled;
4. Please check the dirtiness status of the dirty water tank. If the dirty water tank is full, it may cause the vacuum to fail to work. Please clean it in time;
5. Please clean the suction port of the floor brush or the pipeline of the dirty water outlet and check the roller brushbar whether there are any tangled hair, debris, or obstructions;
6. Sometimes a simple restart can resolve the issues. Unplug and turn off the vacuum, wait for a few minutes, and then turn it back on;
7. Please perform the factory reset, which will erase all your previous settings and the cleaning history.
If the above troubleshooting methods can’t resolve the issue, please contact our local official service center or your seller for further assistance. They will help you in this regard.
