Okay, that could be, but I wouldn't buy a robot hoover that cleans in chaos. For about 250 Swiss francs you can get the Xiaomi Dreame D9 hoover robot, which can clean the flat with a system. The Dreame D9 model is also much quieter than the iRobot Roomba 698 at around 60 dBa.

A robot that cleans according to the chaos principle (drive in everywhere until the sensors react and then turn around and continue chaotically). The result for a robot with laser navigation is that it cleans in a systematic way. Everyone has to know for themselves, but a Dreame D9 for about 250 Swiss francs, which cleans just as well as a Roborock S6 that costs about 400 to 500, the price / performance of the Dreame D9 is incredibly good.

Here is an objective and detailed video where you can find out more about the Roomba 698.
