Water tank

The water tank is the reservoir with a valve that feeds the mop. It cracks along the seams, loses its seal, and the valve gums up from hard water.

Tanks for Xiaomi and Mijia, Roborock, Dreame, iLife and Ecovacs. Price depends on the model.

Check the O-ring and the valve first — both are cheaper than the tank and are more often the cause. A crack in the shell shows up against the light if you fill it and hold it over a sink.

About the water

Put nothing but water in it. Cleaning liquids leave a residue that eventually stops the valve from sealing.
