Question about Dreame X50 Master

The base station cannot be operated without a fresh water connection as it relies on the automatic refilling and emptying of water. This requires a connection to the water pipe to fill the water tank and dispose of the dirty water.

The AI answer is not quite right. You can use the robot as normal even if you don't have the water connected :) of course you just can't wet clean then ;) but vacuuming works without any problems
