Please make sure to always complete the following preparation steps prior to using the MACH vacuum cleaner:

1. Fill the clean water tank with tap water: place your fingers against the groove on the upper end of the water tank, pull it outward to remove the water tank, then open the rubber cover and fill it with clean tap water. Please make sure the water level does not exceed the MAX water line.
2. Install the clean water tank: After filling the clean water tank with tap water, tilt the water tank slightly, align it with the installation hole, then install it back into the vacuum.

3. Add floor cleaner: after removing the cleaning solution tank, tilt the cleaning solution tank slightly, and add floor cleaner. Please make sure the amount of the floor cleaner does not overflow, and only use eufy cleaning solution as non-eufy cleaning solutions may damage the vacuum cleaner.
4. Reinstall the cleaning solution tank: simply attach the bottom of the cleaning solution tank to the vacuum.
