Please note that the suction tube connects to the bottom of the dirty water tank. After removing the dirty water tank, you will have a clear view of the suction tube and the suction tube should be clear of any debris. If there is any debris blocking the suction tube, it will cause the MACH V1 series to trigger an error and the vacuum cleaner will stop working.
Please try the following troubleshooting steps to verify if the issue can be resolved:
- Please upgrade the vacuum cleaner's firmware to the latest firmware version by going to the eufy Clean app > tap the upper right corner on the app's main interface to proceed to the Settings interface > tap Firmware Update.
- Remove the dirty water tank to check if there is any debris in the suction tube. If necessary, please use the included cleaning tool to clean the suction tube.
