Hello,
Thank you very much for providing such detailed feedback about your experience with the Z60 Ultra Roller SA. We sincerely apologize for any disappointment you have felt with the mopping experience and model differences, as this is not the experience we aim to deliver.
Firstly, regarding the model configuration differences you mentioned, we completely understand your disappointment. Different versions with suffixes (such as Ultra Complete and SA version) do indeed have specific distinctions in accessory packages and some feature designs. We have carefully noted your feedback about "unclear product comparisons" and will forward it to the relevant department to improve future product descriptions, ensuring consumers can make more informed choices. You can refer to the following link to view the differences between the Z60 Ultra Roller SA and the Z60 Ultra Roller Complete:

Regarding the "dirty water tank not collecting water" and "overflowing" issues you described, these are usually related to the seal of the water tank or the state of the suction port. We suggest you try the following steps for quick troubleshooting:
Check if the dirty water outlet and filter components are clogged, and clean them promptly.
Open the top cover of the dirty water tank to check if the sealing ring is loose or deformed. Ensure it is manually reset and clean it with a cloth.
After emptying the dirty water, make sure the tank latch is properly secured.
Press down on the dirty water tank after placing it back in the base station to ensure it is installed correctly.
If these steps do not solve the issue, use a dry cloth to wipe the liquid level sensor (metal shrapnel) on the cleaning tray.
If the issues persist after the above troubleshooting, please send the device's SN code, purchase invoice, and the photos of the issues you captured (as attached in the post) to our after-sales support team. Rest assured, we are committed to providing you with a satisfactory solution.
