Same here. Luckily I was too lazy to get rid of it, yet. Now I can actually get some money out of it. Not sure to be happy about it, though.

The mentioning of Valetudo should be more at the top to make people aware of the existing alternatives.

My aged Roborock S5 suddenly stopped working a year ago and only cleaned a very small segment making it effectively useless. Since I knew that data is exchanged with the manufacturer I suspected them to actively prevent the device from working properly to make me buy a new one. Thanks to Valetudo the device is working back again just fine. Meaning there never was a hardware (or software) failure, but a remote issue.
