Functional description

The device consists of a charging station and a battery-powered cleaning robot.
The mobile cleaning robot obtains its energy from a built-in rechargeable battery. The cleaning robot can clean for up to 120 minutes with a single battery charge. It automatically returns to the charging station to re-charge when the battery charge decreases.
The cleaning robot moves systematically. It scans the room with a laser sensor (LiDAR) and then cleans the room step-by-step. It avoids obstacles that are at least as high as the LiDAR tower.
The flat design of the cleaning robot allows it to clean under furniture such as beds, sofas and cupboards. The cleaning robot has fall sensors that detect stairs and steps and prevent falls, as well as collision sensors that detect and avoid obstacles.
The battery for the cleaning robot is charged in the charging station.
If the cleaning robot starts the cleaning work from the charging station, it returns to the charging station when the battery charge is insufficient.
As soon as the charging process is finished, the clean-ing robot automatically leaves the charging station and continues the cleaning work. The cleaning robot also re-turns to the charging station when it has finished clean-ing.
