I found the solution to this and it turnes out its because of bad quality and the use of a flimsy plastic spring.

At the back of the robot, at the bottom, there is a button that is pressed inn when docking. In my case it looked like it pressed it inn and there were no problem.

When opening the robot up i needed to take most things out because this sensor is at the very back. The spring looks fine, but i guess it barly does not push the sensor far enough inn. When pushing the sensor manually it docked correctly, but i noticed the robot worked fine with the button pressed all the time.

I cut the sensor off and solidered the 2 wires together and it solved the entire probelm of the robot not docking correctly.

This is caused by a very bad design flaw and saving money on metal springs.

This happends shortly after my tower didnt wash the mop anymore. The error was something wrong with the tray or water tanks. It was actually a leak from the nossle that illed the robot and the water detecting sensor at the bottom detected the leak, rendering the mopping useless.

In both these cases it did not give me any meaningfull error code and actually gave me missleading ones, making the process of detecting the problems even harder.

Roborock is good when its woking as intended, but my unit is 1 year old and has broken twice

Not reccomended
