No, there's no need. The base tank can last several weeks without any problem. The robot will fill itself up automatically.

Hello Tanjavera
Thank you for your question. The robot's water tank automatically fills itself with fresh water at the suction and refill station. How often you need to refill the 3 litre fresh water tank in the station depends entirely on your cleaning behaviour - how often you want to wet clean, how large the area is, what level of liquid you choose depending on the area, etc.

There is no dirty water tank (as with the new Roomba Combo 10 Max), which has to be emptied manually.

If you have any further questions or uncertainties, just get in touch :) You can also reach us by phone on +41 62 746 06 74 or by email at service@irobotics.ch.

Best regards,
Your iRobot Team
