Hello Guenther.daverda
Roomba 980 works with iAdapt 2.0 Navigation and re-maps your home every time it cleans. The map is not saved. For this reason, it is not possible to clean individual rooms specifically.
You can control this with a robot with Imprint Technology such as Roomba i7150/i75158 or i7558+.
You can find the devices here:
iRobot Roomba i7158
iRobot Roomba i7+ (i7558)
Spartano84's answer is also correct. Roomba has what is called the 'spot function'. Roomba can be placed in the desired location and then cleans the area of approximately 1 to 2 m2 by activating the spot function.
