Question

Why do I get the error message: Please check clean water tank?

---

Answer

The use of a chemical cleaning agent in the fresh water (not permitted) or fresh water that is too calcareous (which may have been in the tank for 1-2 days or longer) can cause the detectors in the water tank to become dirty or corroded. As a result, the robot mop may have problems recognising the water level and therefore displays the error message Please check clean water tank.

Remedy

Mix half a teaspoon of table salt with water in the fresh water tank (alternatively, 2-3 drops of pH-neutral detergent can be used). Shake the tank well, leave to stand for 10-15 minutes and shake again. After cleaning, pour out the water again and then rinse the tank with clear water. Then dry the contacts + / -.

More information

Distilled or demineralised water must also not be used for cleaning. In this case, the detectors also do not recognise water because the pH value is too low.
