Question about Dreame X50 Ultra Complete

You need to change the water in the robot vacuum's docking station periodically, but the exact frequency depends on usage. Generally, you should refill the clean water tank and empty the dirty water tank after each mopping session to maintain cleanliness and prevent bacterial growth. The docking station automatically refills the water tank and cleans the mop pads, but you will need to manually refill the clean water tank when it is empty.
