D20 Pro Plus

Does the robot notify you when your water tank is running low or depleted ?

Yes it does

Really? I have let my water tank run low and depleted many times just doing mopping option only but still no notification about water tank.

There is a floating sensor in the water tank, check if it’s stuck.

Alfredo is right check your floating sensor

Hi,

Could you please confirm whether your model is the D10 Plus Gen 2 or D20 Pro Plus? The base stations for these two models do not include a clean water tank, but the robot's small water tank does not display an error message when it's low on water.
