Please add a cleaning solution to the floor cleaner tank and do not exceed the MAX mark before using the MACH V1 series. If the MACH V1 series triggers an insufficient cleaning solution error when there is a cleaning solution in the floor cleaner tank, this error could be caused by the cleaning solution being unable to dispense from the floor cleaner tank or the floor cleaner tank could be leaking.
Please try the following troubleshooting steps to verify if the issue can be resolved:
- If the floor cleaner tank is leaking, please confirm whether there is a black rubber plug (diaphragm valve) at the bottom of the floor cleaner tank. If you are unsure, please email eufy support and provide a clear photo of the bottom of the floor cleaner tank.
- Check whether the floor cleaner tank is able to dispense cleaning solutions without issues. Please remove the floor cleaner tank, press both sides of the diaphragm valve at the bottom of the floor cleaner tank with your hands, and then expose the cleaner outlet in the middle to verify if the cleaning solution can be dispensed due to gravity. (Keep the diaphragm valve facing down)
- If the cleaning solution is able to dispense without issues, please install the floor cleaner tank back into the vacuum cleaner, turn on the floor cleaner switch, enable smart mode, and increase the vacuum cleaner's suction power by holding down the trigger on the vacuum cleaner for five minutes to observe if the cleaning solution is being dispensed from the floor cleaner tank.
